  1. Hi guys, I'm going to buy a spare bulb. Got a Lumatek Aurora 315 Ballast. Read here and there the Philips Green Power are top notch bulbs. Actually, they're a bit cheaper than the Lumatek bulbs. So which one would you choose ? Thanks !
  2. a 600w grow light? Im only asking as I dont really see it to be fair. I grow (or have grown) with all manner of lights, but not CMH, I use CFL for veg only as the buddage is a bit light any airier than HPS, even when you pound the plants with lumens... I would assume the same principal with CMH, but stand ready to be corrected... Surly the 315w would have the same efrect as CFL lumenwise? After all I understand the 'closer to daylight' spctrums etc. The same can be said the for PAR of CFL on paper, but you just need the light, its pretty much as simple as that. WE tried sulphur plasma for a while as well, the bit I still dont get is; if the light is so close to daylight, then are there two bulbs needed again?...Surely if it was 'that close' then one bulb would suffice, after all its not like the sun changes bulb, it just gets either closer or further from the equator... I would have thought that the PAR of the CMH would make up, at best, the odd 85w to equal a 400w HID - but taking that to a 600w HID comparrisson makes me dubious... after nearly 30 years of cannabis cultivation I have seen and grown with many things but I aint never seen a light that performs equally to a light twice its lumencount. I like to big up my grow style as much as the next man, thats why, like everyoine else, Im posting here - but really? 315 is the new 600? - Spock with a beard? ! think not.
  3. Sorry if I’m posting in the wrong place or this question has already been asked. My current setup is 4, 315W CMH with exodus bulbs. Went down to my local shop to buy the Philips 942’s & 930’s after reading the thread and he’s recommended me to buy 2 x 600W Daylight CMH bulbs and showed me the spectrum which looked very impressive. (I’ll post it below) Could anyone help me out please and let me know which is best: Stick with exodus upgrade to Philips for £800 upgrade to the 600W for £200
  4. hello and welcome to The Cave, This will hopefully be a record of a successful grow but, I'm promising nothing more than a really good go from a crazy old bear. First the Space(s): I will update each space as we reach it (veg and flower are also separate) Nursery is a small cupboard with mish mash lighting and clip on fans for air (not ideal but it is only a nursery) The lighting for the seedling stage is 1/2 a T5 4 tube (half is fookeded) Nutrients and compost : Thanks to @Intense Nutrients Matt for kindly helping out so I could run the full organix range on this run! Top man So, I'll be using ; Granules Runzyme Foundation Grow Bloom These will run according to schedule, I will make any adjustments as we go but from what I have seen that won't necessarily be required... we shall see. Compost: Clover Multi-Purpose (on it's own for seedlings) Wormcast Kelp Meal Dolomite lime Ecothrive charge Other information: Water - my water is horrendous out of the tap (very mg heavy) I amend it with Canna Mono Calcium to a ratio of 3.5 : 1 Cal : mg I add this information as I get asked a lot about water and I hope this will be a good reference point for future enquiries. Ok thats it for the intro on space etc .... heres the pics, 2 of each got dropped in for a soak and all came up! Out of the gates and we have 4 runners Cheeky shot to show non destructive seed removal Runty PM on the right was the last to show and has been a tad slow in getting herself going but its only very early and everyone is alive!!! and now , in keeping with bear necessities... We have the "Pandometer" for measuring level of excitement Week 1 rating is .......... back in a week to see if its getting the Panda up SSAS (Stay Safe and Stoned) Obie

    300w CFL for Germination and seedlings. 315w CDM/CMH 400 HPS
  6. Hi, I'm looking for a CMH 315W digital ballast. What is a good brand? In the Netherlands the number of Brands (I could find) is very limited DimLux Lucilu Lumatek Hortilight .... Please advice me Thanks, Tracker06
  7. Help needed! Currently I am using 400W HSP in a 0.80 x 0.80 x 1.60 m (approx. 2.6 x 2.6 x 5 ft) tent. But I want to switch to CMH/CDM/LEC. After a lot of reading, I decided to start with a Philips 315W 930 Agro for veg. and flower. But I need help to find the right one. Suppliers simply use the same terms for different types of lamps, see the list. But usually they don't show pictures of the box or the type printed on the bulb. How can I be sure I'm buying the right one? Can someone explain what to look for? As far as I understand the box and Bulb should both state "Greenpower" and "CDM-TP", see image. Is this correct? Thanks, Tracker06 Picture found on the internet
  8. Hello all, I posted ups a thread a few weeks ago but it got massively off topic and I have had time to do some more research. Previously I have grown 8 plants (Autos) in soil in a converted walk-in wardrobe under 2 x 600w HPS. I have since moved and it would be better suited to go inside a tent so was wondering the best size to go for?: 2 x 630w (dual) CMH lights? I was thinking around a 1.2m x 2.2m x 2m tent? Thats giving me room for 8 plants with the reservoir outside the tent? Or would 2 x 315w be enough? 1 x 630w (dual) CMH light in a 1.2m x 1.2m x 2m tent allowing 4 plants and the reservoir outside the tent also? Or would 1 x 315w be enough? Secondly, I'm stuck between the Alien RDWC or the Alien Easyfeed? Cost isn't a factor, what matters is quality, ease or grow and speed really. Like I said, I'm happy to pay extra for the RDWC plus I don't need to deal with loads of soil either. Lastly, for the above two tents, what size RDWC or Easyfeed pot size would be best? I was thinking around the 20litre mark? Cheers
  9. Well a bit of a latecomer to the Dinafem X Intense Nutrients grow off show but finally here we go. First of all a big thankyou to @Dinafem-Mark and @Intense Nutrients Matt for making this happen and supplying the seeds and Intense nutrients Organix range. I've been looking forward to this as i've never grown any Dinafem before but these Blueberry and Ocean Grown cookies sound delicious, also new to the Intense Nutrients Organix range although for my current grow in flower i have been using Organix Grow and Bloom with excellent results so far and the plants seem to love it. This grow i will be using the Organix Granules, Grow, Bloom, Foundation and Runzyme kindly sent to me for this competition by @Intense Nutrients Matt. As a quick rundown this grow will hopefully be just 1 each of the Blueberry and Ocean Grown Cookies in compost, ighting for veg will be T5's, 250w and 400MH, mixed spectrum 400w HPS and a 315w CMH 930 Agro Lamp for flowering in a Scrog. This grow will be started in my DR90 tent for i expect most of vegging and then the girls will be transferred into my main 90cm x 90cm x 210cm Growdrobe for rest of veg then flowering. Only one seed has just broken ground so far so tomorrow will be Day 1 for her, i'm sure the other will appear anytime just now. Before i start the diary here is a rundown of my setup, equipment and methods used. New eqipment has also been purchased for the DR90 tent as you will read below, so all new environment and things for this grow but all should be good. SECRET JARDIN DR90 TENT & INTAKE/EXTRACTION. So this grow will be started in my Secret Jardin DR90 tent, i've owned this for around 10 years but this will only be my second grow with it so its virtually new and kept in its original bag, as some of you know i usually grow in my 90cm x 90cm growdrobe but that is currently occupied with a grow in flowering for a few weeks yet. So same size tent as my normal growspace but a little less headroom. Now i used to use Variacs to control the intake/extraction but i have just purchased a SMSCom Hybrid controller to control the environment in there. The Hybrid is a superb device and does its job perfectly controlling the temps in there. When i used to use Variacs i sometimes had to slow the fans further at light off in cold times but this Hybrid controls everything light on or off to keep a stable temp at all times. The Intake and Extraction fans controlled by the Hybrid are both 5" Rucks although the intake is not as powerful. The Hybrid did cost me just under £250 but its worth every penny in my opinion it also has a feature where every hour at only light off it will crank up the speeds of the fans one notch just to remove that extra moisture in the air that builds up at lights off, i can see this being very useful in flowering when a high RH is not good, this feature does not have to be used and the unit comes complete with a shade to cover the sensor if not required. Fans are completely silent with no humming whatsover like the Variacs. The Hybrid has solved the variable temps in the tent and this means i can leave it and forget, good thing too in summer with higher temps it will raise the fans speed on its own to keep temps stable. The growdrobe is actually a walk-in wardrobe with 3 brick walls and the door so i suppose this explains why the growdrobe runs cooler than the tent although its in the same room. The Carbon filter is a 5" Rhino Pro and everything is connected up with Phonic Acoustic ducting. A pick here of my DR90 and Air Cooled Hood connected. > And my new SMSCom Hybrid controller which fully controls the environment silently. > LIGHTING FOR TENT- SEEDLING/VEGGING. The lighting for the tent in eary veg will be a Maxibright T5 4 tube fluorescent, 96w of power (24w each tube) and measures 59cm(W), 37cm(D) and 6cm(D), on/off switch and is wired to a Maxiswitch 2-way contactor (10Amps) and Grasslin timer, i have 2 of these units and i really recommend them for vegging as the keep the plants short, give off little heat and the light spread is great, i've vegged for 3 weeks using these units in the past and the result was very stocky healthy looking plants, they seem to love the light spectrum. Later on in veg i will swap the T5's for a 250w MH then a 400w MH, after that maybe a 400w mixed spectrum HPS all in a 5" Air-cooled hood. Pic of one of my T5's setup in my main room. > So the tent is ready to go, temps at light on even under the 400w MH is no more than 26c, light off around 21c. Once vegging is nearly done the girls wil be transferred to my main growdrobe, set as below. > GROWDROBE & INTAKE/EXTRACTION. The room is a converted walk-in wardrobe, The drobe measures 3ft x 3ft 7ft and covered top to bottom in the Orca Grow film, everything is covered including the shelves and door. Easy to put up as its much stronger than mylar and almost impossible to tear, no glue or paste was used in the room as i stapled it on with a heavy duty staple gun. It's very bright in the room and the Orca is very easy to clean as spillages just wipe off being as its waterproof. Temperatures are always stable at around 27c lights on, about 22c off. Intake is a 5" twin speed Ruck fan fully controlled by a 3A 0-240v Variac and the extraction is a 5"Ruck fan with STR Voltage stepping fan controller with a 5" Carboair carbon filter connected to 90 degree bend and Acoustic ducting. Air circulation is x2 6" clip on fans. Thermometer/Hygrometer. There is a steel Scrog net i made to fit the growdrobe which will also be used this grow once the plants are in there. My growdrobe with Scrog net fitted > 3a 0-240v Variac and STR Voltage stepping controller. > LIGHTING FOR GROWDROBE- FLOWERING. Light for Flowering will be the Maxiibright 315w CMH system with the 930 Master Greenpower Agro lamp, i did used to own the 942 lamp too for veg but ths blew a few weeks ago and decided not to replace it and just veg under MH. The shade is a Maxibright Focus cmh dedicated reflecftor.(old pic, ignore the 942 lamp and shade adaptor as they are not used now) > SOIL/NUTRIENTS This grow the soil will be the Clover Multipurpose compost, only my third time using this but my previous grows had no issues so i'm going to carry on using this for now. I've used PM compost for years with great success and also used Jacks Magic successfully but found it a bit rich for some plants. Nutrients will be Intense Nutrients Organix Grow, Bloom, OG Granules, Foundation and Runzyme kindly supplied by @Intense Nutrients Matt SEEDS. The seeds used for this grow will be a single Dinafem Blueberry Cookie and a single Dinafem Ocean Grown Cookie. 5 of each of these seeds were generously sent for this comp by @Dinafem-Mark I'll only be germinating the two seeds (one of each) as i do like growing two plants in a Scrog which perfectly fills my space with 2 big pots. The other 8 seeds will be started at a later date, probably next grow if they turn out tasty. BLUEBERRY COOKIES > Blueberry Cookies by Dinafem Seeds is a feminisedcannabis seed descended from a Girl Scout Cookies and our elite mother Blueberry. Fully aware of the immense popularity of the Cookies family across the USA, our team of breeders put their hearts into creating a hybrid that would bring the amazing traits of this world-renowned strain to their limit. Born in San Francisco Bay, Girl Scout Cookies was named after her delicious uncanny scent reminiscent of freshly-baked cookies. Is there any better match for this sweet cocktail than a Blueberry with mouth-watering aromas of fresh blueberries? After a long cross-breeding process aimed at only selecting the traits that would outdo the original ones, our team of breeders has created Blueberry Cookies, a hard-hitting hybrid called to surprise the palates of hard-to-impress veterans. Morphology Blueberry Cookies grows into mid-sized plants that can reach 3 meters in optimal conditions when cultivated outdoors. Her branches are solid and her internodes are rather large, meaning light can easily penetrate the canopy and reach the lower branches giving way to evenly distributed, elongated, amazingly thick, and resin-packed flowers. All Cookies hybrids are famous for the purple nuances covering them, but this one in particular, thanks to her Blueberry side, is a spectacular display of reddish, violet, and purplish hues. Besides, with a moderate calyx-to-leaf ratio, trimming her will not be a pain in the ass. We recommend safekeeping her sugar leaves for the delicious resin on them can be used to make incredible concentrates. Expect extremely thick and heavy spiky-looking buds with large calyxes, a rarity that ordinary Kush genetics don’t generally have. She’s indeed so beautiful that even us, the Dinafem team, can’t stop staring at her. Yield Blueberry Cookies is noted for the density and weight of her buds. The best things are said to come in small packages, a saying we totally agree with. Despite their reduced size, her flowers are remarkably compact and come with a thick coating of frosty resin glands and off-the-charts aromas. Aromas and flavours The popularity of the Cookies family stems primarily from their enticing aroma and no wonder. While U.S. Kush strains just offered earthy and fuelly tastes with some coffee undernotes, the Cookies smell like pie. They’re so delicious that they make you want to take a big bite out of their dried buds. That’s why our team of breeders thought the fruity perfume of Blueberry will make the best companion. This is how Blueberry Cookies was born: a tasty fruit pie with intense nuances of wild berries dancing together in a cake-like, Indica background. While growing, buds give off a strong yet fresh fruity scent. However, after the curing and drying, it turns much sweeter, more or less like smelling pastries. Effects Coming from a U.S. family of genetics, it couldn‘t be otherwise. Blueberry Cookies delivers a crushing head and body high. Thanks to her Indica dominance and her 18% THC levels (with 0.1% CBD), this strain produces a highly narcotic and muscle-relaxing effect. Cultivation Blueberry Cookies is very easy to grow and thrives outdoors. She is incredibly vigorous, meaning she loves stretching during the growth stage. Outdoor growers will obtain bigger yields for this plant shows her full potential when grown in the open air. So, without nosy neighbours nearby, she should be put no limits. Direct sunlight will help Blueberry Cookies fully develop. There’s a big difference between a vigorous growth and a weak flower development produced by the lack of sunlight. This beautiful purplish plant, in particular, copes well with outdoor conditions. If provided with a bit of attention, a standard feeding regime, and a warm environment (also suitable for northern climates), she’s sure to produce top-quality crops by early October. Flowering wraps up in 55-60 days indoors, where we recommend using organic growing methods so as not to modify her tastes and aromas, which, along with her mind-blowing effect, are the main reason why we should all grow her this year.

The popularity of the Cookies family stems primarily from their original taste as well as from the quality and exclusive traits that have earned them a well-deserved place among the most important U.S. cannabis heavyweights along with OG Kush and Sour Diesel. And the truth is that those who try her extraordinary tastes and aromas get instantly addicted to them For that very reason, no sooner did we get our hands on an elite clone of Girl Scout Cookies than we knew something really special had to be done. And is there anything more special than crossing the most famous Girl Scout of the west coast and another Californian all-time classic as is the incredible OG Kush? From this powerful marriage comes Ocean Grown Cookies. As always, it became our obsession to bring the best Cali taste to the highest pitch of perfection. And that's exactly what Ocean Grown Cookies is: a cannabis jewel born close to the Pacific boasting the strong scent that has pushed American strains to their legendary status. Morphology Ocean Grown Cookies grows into mid-sized plants that can reach 3 meters in optimal conditions when cultivated outdoors. Her branches are thin yet solid, although using stakes during the vegging period is highly advisable for they'll let more light into the canopy and the plant will, therefore, produce more pointy and bulky buds overflowing with highly resinous trichomes. They’ll also prove useful for preventing the branches from snapping due to the weight of the flowers. This plant is the perfect blend of Girl Scout Cookies and OG Kush. With rather long internodes, she acquires a beautiful purplish colouring that makes her a sight to behold. Besides, those who find trimming a nuisance will love hearing that she presents an adequate calyx-to-leaf ratio.

Besides, those who find trimming a nuisance will love hearing that she presents an adequate calyx-to-leaf ratio. Aromas and flavours It is thanks to this that Cookies hybrids have carved out a place among the most reputed strains of all time: their tastes and scents are simply amazing. We wondered whether we’d manage to give the already incredible aromas of Girl Scout Cookies a twist by crossing her with OG Kush, another world reference for quality U.S. flavours and predecessor of GSC. We soon realised, though, that this was indeed a winning bet. That’s how Ocean Grown Cookies was born; a mind-blowing strain noted for her potency and distinctive aroma, hallmark of the west coast: a blend of earthy and Kushy scents with sweet and fruity undernotes. This strain provides U.S. cannabis enthusiasts with a breath of fresh air because she still keeps the traditional Kush background intact thanks to the OG Kush genes in her. Something in between the typical diesel scents of the U.S. family and the innovative sweet and fruity tastes, similar to those of pastries, that are killing it right now across the States. This perfectly balanced blend makes Ocean Grown Cookies a great choice for seasoned palates looking for new and surprising flavours who don’t want to give up on the intense aftertaste of Californian Kush hybrids. Effects The high delivered by Ocean Grown Cookies can only be described with one word: devastating. Her crushing THC levels of around 20% and her almost non-existent CBD content (approx. 0.1%) make her particularly powerful. Her psychoactive effect is incredibly potent, narcotic, and long-lasting. Expect a gentle blow of euphoria that goes straight to the head and turns into a nice feel of physical relaxation over time. Powerful, hard-hitting, and sedative, in true Californian style. Cultivation Despite coping well with northern chilly climates, she does prefer warm Mediterranean-like environments or greenhouses. However, given her medium size and bushy form, she’s the perfect candidate for growing indoors. By meeting her basic needs, we'll easily obtain great results with her. For the delicious taste of Ocean Grown Cookies to remain untouched, organic growing practices are highly recommended. Besides, given her Indica dominance, this jewel is not a heavy feeder, so a standard diet should suffice. This way, we’ll maximize her incredible scents. We promise: it’ll be worth it!

  10. Hello all, I posted a similar question a few weeks ago but the thread went very out of topic so thought I would ask again in the lighting section. i have previously grown 8 in soil before in a converted walk in wardrobe but with 2 x Lumatek 600w HPS and all was good with the grows. This time I’m investing in some CMH lights, tent and RDWC (first time) setup (Alien). Looking to grow 8 in 20ish litre pots. So I’m either looking to do the following if the space is correct or what size tent and lights do I need? This is pretty much what I was thinking and also posted in the Hydro section but it’s more suited in here or environment I guess? 2 x 630w (dual) CMH lights. I was thinking around a 1.2m x 2.2m x 2m tent? Thats giving me room for 8 plants with the reservoir outside the tent? Or would 2 x 315w (Single) CMH be enough? I could throw in a few corner LED lights also maybe or perhaps 3 x 315w (single) CMH lights? 1 x 630w (dual) CMH light in a 1.2m x 1.2m x 2m tent allowing 4 plants and the reservoir outside the tent also? This isn’t ideal really as would like 8 on the go to be honest. I’m not fussed about the cost really, just want quality, ease of growth and speed. With regards to the CMH, what are the better brands? Like I have mentioned, looking for dual ones ideally with the ballast built into the hood but being built in is not essential. Cheers all, Hop
  11. Hello all, New house, new grow equipment needed! I have grown successfully grown 8 a few times in a corridor like walk in wardrobe in the past using 2 x 600w HPS Digital Lumatek's but this time im going a little more advanced and changing from soil to RDWC and HPS to CMH while monitoring using some sensors, some code and a Raspberry Pi. Im looking for the best and within budget (£350 each, not including bulbs) 630w fixture. So far I have found the following and was wondering which is best really. As you can see, some are a little over budget but I could have a think about it. Also, as the grow goes along I intend on putting in some 30w'ish tall corner LED lights to supplement the grow while in flowing, bit like the X80 Flower Bar's by Kind. I would be growing in a 1.2m x 2.6 x 2.2m tent apart from if I went down the Nanolux 1000w CMH path which would then be a 1.4m x 1.4m x 2.2nm. Just wondering if you could let me know which are the better ones out of the list below. I have tried to make it as user friendly as possible and like I mentioned before, as im growing in a tent this time I would rather not have an external ballast as the principle of using a tent this time is to make it easy to take down etc so I don't want to be screwing ballasts into walls etc ideally. £349.99 - Nanolux CMH 630w Full Fixture light kit - No lamps - Fixture £249.95 - SuperBright CDM Reflector 2 x 315W - No lamps - Fixture £249. 95 - LUMii Solar 630w Double-Ended (DE) CDM Grow Light - No lamps - Fixture £449.95 - Maxibright Twin 630w CDM Grow Light Kit - With Lamps (930 Elite Agro & 942 Mastercolour Veg & Flower) - Ballast £324.95 - Lumatek Tekken Pro Miro 630w DE CMH Full Kit - With Lamps - Ballast £474.95 - Nanolux CMH 1000w Full Fixture light kit - With Lamp - Fixture (single CMH and 1.4m x 1.4m x 2.2m Tent) £239.99 - SunStream 945 Watt Ceramic Metal Halide CMH Double Ended Grow System with Bulb (945W CMH DE) - Fixture
  12. Hello again all! Getting back into growing again after around 4/5 years of buying due to house move etc. I know this is the lighting section but these questions etc will help decide the light system I go for due to the size of the tent. So instead of soil, this time I’m going with either a Bottom Fed or DWC Kit by Alien or IWS) The kits I have narrowed down to so far are either these: 8 Pot XL EasyFeed System 30L system by Alien EasyFeed IWS 8- Pot R-DWC Pro Undercurrent System - With 25mm IWS Flexi Pipe 4 Pot XL EasyFeed System 30L system by Alien EasyFeed ccvv IWS 4-Pot R-DWC Pro Undercurrent System - With 25mm IWS Flexi Pipe Now this brings me to the lighting/tent size. As you can see I would need a 2m x 1m for the the 8-pot systems or a 1.2m x 1.2m for the 4-pot system (I think?) Lighting wise, in the past I have used from cheap 400w magnetic ballasts to 2 x digital Lumatek ballasts with HPS snd MH bulbs. This time it’s CHM 315w or LED (LED prob from @diyleduk on here or a recommended pre built LED from a good supplier). In the 2 x 1m I think I would struggle with just 2 x 315m CMH or 2 x 400w LED? From my old calculations and research I could really do with 2 x 600w min for that space? In the 1.2m x 1.2 or 1.0m X 1.0m I could get away with either 1 x CMH 315w or 1 x 600w LED? What do you think regarding the 8 pot system and lighting intentions?
  13. Here is a blog that we're especially proud of, being that we've created a downloadable cost calculator that allows you to input all the variables such as wattage, timer cycles and energy prices as they change. We initially had a beautifully presented equation, but alas, 'computer said no'. "How much does my light cost to run? With lights by far being the most energy consuming piece of equipment in your grow room, that’s a significant chunk off your monthly electricity bill. You can either go through our simple mathematical equation, or download our electricity cost calculator we’ve created to determine the cost of running any given light over a grow cycle and see how much you’ll save on electricity alone..........." https://diyleduk.com/blogs/news/how-to-work-out-your-running-costs-with-calculator-download -Craig
  14. Finally can get this going Again this diary is for the single Trainwreck I have going in a multi strain grow. Didnt look like this thread was going to happen, after popping a single Trainwreck into damp coco this seedling popped in 2 days It didn’t look great one of the tiniest things I’ve seen and looked a runt from the go then day 4 veg it starts to pick up. At this point it was potted up with all mix and put under the 315cmh today day 7 veg it’s finally starting to go. Today 1st watering with intense nutrients foundation 2ml ltr.
  15. Hi I am very new to growing weed and still have a lot to learn-i'm just half way through my first grow and as I think it's going pretty well (touch wood) I'm sure I can still improve my tent. It's 2/1/2 ten with wilma 8x18l system filled with clay pebbles. I have 4 auto vertigo plants from paradise seeds on left and 8 quick ones from royal queen seeds on the right. I use 2x mars hydro tsw2000 panels and they are doing a good job so far but it looks like they are not enough to get a max potential of them plants. I read a lot on this forum and a lot of websites plus all youtube growing diaries and my mate grows for years in soil under hps lights. Now to the point: These mars panels give very good light but I don't believe in what they claim that they flower 90/90cm as I have measured light intensity with my phone (I know its not best tool but shows the difference) 10" directly below the panel light appears to 4-5 time more intensive then just 4" to the side of it. When I was looking for best light for my tent (and value for money) I though 90/90cm will be ok but my plants take all the space of that tent now and I started thinking of upgrading my light. I don't really want to get rid of them panels as they aro good just don't cover 100% of my growing space(and I have paid nearly 500 quid for them. First idea was to get one more led panel but my mate suggested hps as he knows them well as he was growing under them for years (they were old street light etc up to 800W) but as I was going through the forum CMH got my attention. Does it make sense to push my led panels close to the sides of the tent and set them on a slight angle and place CMH bulb right in the centre of the tent with more of the flatter reflector to cover more surface? ps. Are there any less powerful cmh bulbs then 315W or can they be dimmable? That's how it lokks now (week ago in termns of plants themselfs):
  16. Well i'm not happy at all with these CMH lights, the 942 Daylight lamp has just died after only around 3600 hours of use! Luckily i went into the growroom just before the light was due to come on as i took some pictures to update my grow diary, pics took the light came on and as soon as it got to its full brightness it suddenly went off. I did not touch anything and waited for the bulb to cool, not long as it had only just come on. Looking at the lamp from underneath i could see a brown mark on the ball thingy inside the the lap so i unscrewed it. I put my 930 Agro lamp in and the light came on perfectly and stayed on. The 942 lamp is obviously blown or something, i cant say that brown patch was there before but it looks suspicious, i do know it does not work now and not happy at all as these lamps cost around £100 each last time i checked. I purchased the whole CMH kit back in 2017 but the 942 lamp has only had around 3600 hours of use i'd say. I've done around 5 grows with it, i use T5 lighting for the first couple of weeks and average 4 weeks of 942 lamp veg, then maybe up to a couple of weeks under the 942 at the start of flowering... So thats roughly 28 days of 20hrs use which is 560hrs, 14 days of 12hrs = 168 so total average for a grow 728hrs.. 5 grows use is only 3640hrs use and they say the average life of these lamps are 20,000 hrs! Has anyone else had one of these lamps die prematurely? Looking at the box of the 942 lamp it says manafactured in 2016 although i did not purchase it until mid 2017. I suppose i can't do anything about it now as Philips or the growshop would not interested. I'm just glad i was in the growroom as it was due to come on and i saw it go off after a couple of minutes. The plants are at Day 7 into flowe so the 930 Agro was due to go in there soon anyhow. Thing is, now i'm expecting the 930 to go soon too as its not had so many hours use yet. Here a picture of my CMH kit and both lamps. > See the brown mark on the bulbous thing? >
  17. Hi guys, finally got around to getting a small tent for my 2 somango xl's. They're currently under a little 10/15w ikea led, which in fairness has worked wonders for them up to this point. But the time has come for an upgrade and I need them to start putting on size in veg now if I want smoke by christmas. They've also just been transplanted to 6.5 litre pots, will likely repot before flower to something bigger (maybe 15l+? depending what fits). Hoping to pull 7 oz's at least between the two plants. Have explored options with LED, liking the minimal heat and low energy costs. Would like something at least 200 actual watts, would an led of this power achieve the 7oz goal? Also open the hps/cmh, just not sure which ones are a good safe brand, a lot of shite online. Would appreciate some real world recommendations from you guys!
  18. Am I ok to use a 945w De CMH alongside 2x HPS running at 250w for vegging my 8 stardawg babies? What problems could I face or what would I benefit? Also, when I flip to flower (12/12) I will crank the 2 HPS lights to 600W. That’s 2x 600w hps and the 945 de CMH over 8 plants that live in 60/40 coco. Any advice would be much appreciated
  19. Hello y’all. So I’m starting my first grow on a 2.5x2.5x5 tent and I still couldn’t decide which light to choose, online is just so much information it makes it hard to just choose one. Looking to buy a full lighting system for less then 200£ that will give me killer buds in this small space. It doesn't need to be led necessarily but since I live in a shared house I think it would be more cost effective. Open to any suggestions; my goal is to get some killer frosty buds to myself without going bankrupt. Thank you in advance everyone
  20. Hi All, As it says above really, what spectrum CMH do you guys recommend to go alongside 2 x 400v 600w Philips Green Powers in a 1.2m x 2.4m tent? The CMH will be in a Maxi Horizon reflector... Ta Fax
  21. Hi all, I am a bit of a newbie grower am only on my 4th run and could use some advice regarding lighting setups and energy cost. Any help would be much appreciated. My previous setup was 1 x 600w HPS and 1 x 400 HPS both on magnetic ballasts in a 2x2 metre tent (6.5ftx6.5ft) for 18 plants. I had good success on this the only problem was the electric prices, they were extortionate. I decided to switch on this run to LED lighting as it was a lot more energy efficient so i purchased a 1200w Bestva duel chip LED. In this setup i only run 12 plants used a part of the tent and supplemented the 1200w LED with 2 homemade 300w LED's. I was expecting to see a drop in yield compared to the HPS's but on week 5 of flower it feels as if it was not worth the time and effort with what im looking to get off them. For the next time i am going to go back to 18 plants, use the whole tent and add more light. Here is where i need advice. My 1st thought was to buy another 1200w bestva and run both of them but after reading some reviews on here it seems as if the brand is a load of shit and judging by my yield i agree with them. I now am looking a CMH lights and was wondering if 1 x 315 CMH plus 1 x 1200w in that space would be enough. What are CMH's like on the electric? So would i be better off either having in a 2x2m tent: 2 x 1200w Bestva duel chips LED's 1 x 1200w LED & 1 x 315w CMH 2 x 315w CHM Or would it be better to go to 1 x 1000w HPS and purchase a digital ballast. I know HPS are the best but with running multiple fans to keep the heat down i cant be having a £3000 electric bill. So i am looking for something which is gonna be best on the electric and for my yields. Any advice is appreciated. Thanks
  22. Been a while so I thought I'd do another guided tour of my pc grow. Here's the spec list: Cab: Standard PC tower case 18x8x20 inches (WxDxH) Lamp: 100w Philips Mastercolour Elite 930 Ceramic Metal Halide running on a Tridonic PCI digital ballast Medium: Canna Coco Pro+ Nutes: Canna Coco A+B The regime is perpetual, so the light is on 12/12 permanently with a new plant added to the cab every month or so. I start from seed but take cuttings as soon as possible so I can keep the cycle going. After a little break earlier this year I am now ready to start another cycle, so sit tight and I'll show you how I grow in a 1 cubic foot space.
  23. Newbie on here but been growing for percy for several years, not a novice but by no means a master gardener. I've been trying to grow bud to the same standard that I can purchase, ie some serious sticky stinky dank. I grow in a 1.2 with 1000hps, in soil, usually 4-8 pots depending on time. I have around 12 completed grows, all with reasonable results, yeild wise (from 23-34 oz). My temps, water/feeding, air circulation, rh etc are all pretty good and consistent with the odd hiccup due to weather. I have only ever grown with feminised seeds and now know this is a mistake in my quest for icky. I also know 1000hps with 7' ceilings is not helping. That said I have still grown acceptable bud that gets you high, but nothing close to the import treasures I can buy locally. My next grow will be using reg seeds from either FDM, Ugorg, ACE or Oni, maybe subcool or purple caper. So hopefully thats the genetics sorted. I have also swapped out my 1000hps for 2xcmh, which should bring some UV to the potency party. I have been pretty unimpressed with every female bean I have grown in regard to it being high grade. They have all got me stoned. But that's like saying electric white is great cider cos it still gets you pissed.... I'm hoping some more experienced soul's on here might be able to reassure me that I'm not on a hopeless quest or even give me some pointers in the general direction of where the fire lives.....
  24. I’ve read through the post about cmh 315. Didn’t quite make the whole 200 + pages though quite a lot of mixed reviews.. anybody got got any pictures of bud or links to diary’s with people using them. Interested in the quality of the bud. Im getting a bigger tent 2.4 x 2.4 and was wondering would 6 cmhs be a good light source in this size tent? thanks
  25. Hello! pictured are some zkittzo & Sour Orange Diesel sprouted. It has begun!
