  1. Please move if posted in wrong place Hi everyone. Been reading on here for a while found a lot of helpful information that’s helped me with my first few attempts. Long story short I started growing to help my mum who had terminal cancer with pain relief, fast forward 18 months and I’m now on my 4th grow. I’m struggling to achieve gpw and think this is down to my environment. I have a 1.2m bloomroom loft tent. I have a 6 inch outtake with a rhino filter. Currently using passive intake with a bit of ducting from room below. Running a 600w hps with dimmable omega ballast. X2 oscillating fans, humidifier for veg. 700w oil filled rad for lights off. My fan is a rhino thermostatic but I don’t think the temp control is very reliable. I’ve been using 11l pots with pure canna coco. Using canna range a and b, rhiz, cannazym, boost and pk. Swapped pk for bloombastic on current grow as advised by someone better than me lol. Watering every 2 days up to 2.5L in flower! Don’t seem to be getting the growth I would like in veg and seems to take forever for them to gain size! Now for the questions please! Do I need an intake fan? If so what size? Recommendations on fan controllers for intake outake and heater? Or easiest way to control them all? Would I be better doing 9x6.5l? Less veg time? If so would I put them straight under hps from cutting? A lot more info to share with you guys if you need any to help me! Sorry to ask so many questions on my first post! Thanks in advance
  2. Hi, I’ve been making a lot of changes to my growing setup and would be grateful for any advice I can get on the ventilation especially if anyone is familiar with this size tent. Up to now I’ve been growing with LED’s in 2 DS60’s but I got rid of them all for this grow and bought a 120 x 60 with HPS lights so I could make better use of the space and equipment. I’m just about getting away with one 600w HPS using passive intake from the attic and 5” extraction to a vent also in the attic but temps hover around 30 so it’s borderline. The Prima Klima 125mm fan that I’m using for extraction has a temp probe on it so I was thinking of moving that to the intake so it could click in when temps hit the high 20’s. Then I’ll go get another, larger Prima Klima. I’ve never looked to adjust the speed so a 2 speed basic model will do the job fine. Thing is, what size would I need to move to make a big difference in temps ? Would a 150mm make a big difference or should I go bigger ? Cheers..
  3. Hi All I hail from the emerald isle, though spent most adult life in London. Had to come back here (northern part) a few years ago. I'm just starting out growing. Last summer, without any reading, bought an AK Automatic x 2. Tried the papertowl thing, but forgot to water it. It died. Second seed, straight to soil in summer (indoors during night, day outside) autoflowering. Came on a serious pace, til i killed it by overwatering, and putting in a pot with no drainage. Got three narcotherapy autos from barneys seeds. Got a 300w cfl dual, planted seeds, two in small pots with numerous airholes all round in 50/50 mylar, and one straight into an 18.6L fabric grow bag. The one in the grow bag was three times the size of the other two, it was at least ten inches from seed around week three I think, then because I just had the lamp suspended above plants balanced precariously on a mirror, and ikea box (didn't know about grow tents), it collapsed, and two small plants were killed, and the big one, was cut in half. I kept it growing, moved it into a 50cmx50cmx100cm black orchid tent, with fan, but no extractors, just vents open, for airflow, as there is little scent from it. Started nutrients, but fucked that up as well, as I realised i ordered the Canna hydro specific nutes. Anyway, she is fighting to the last, and a mate gave me a scientific level microscope with four different lens strengths. Strong enough to pick up the striations in metal. So, I'll use that to check up on her trichomes (I've been reading round the clock and watching videos, as I'm disabled, so have the time to devote, well, all my time, to learning very quickly, and am taking great delight in simply growing something I KNOW the strain, and having the pleasure, in due course, of smoking something I knew as a tiny seed.) for the right time to harvest......need to read and watch more about drying and curing... Anyway, I'm sorry if this should have all been posted in different sections, but my disability affects my, er thinking, so sometimes if i don't put it down when i think of it, i forget entirely. I just need some advice. Being an all in sort of person, I bought 3 lamps, apart from the beginner cfl. They are a dual 600 hps, a 600 veg hps or mh..one red and one blue. Also bought a cheap chinese "80 watt true output" led multi spectrum, as the price was ridiculous, but reviews good, and thought it would be an experiment. But to get to the point. As I said, the black orchid tent 50x50x100, which I'm super pleased with as i got it from the ventilation hub on ebay, over 25 cheaper than on amazon, is i think, only suitable for one plant? As cash is a bit tight, I can't at the moment order a large black orchid suitable for up to four to five plants, so after watching a vid on youtube about making your own grow space using cardboard, I ordered two double thickness cardboard wardrobes (used by movers to put your shirts into straight off the peg), and planned to join them together. They are double thickness and measure 50+ (few extra cms) square at the bottom, and over 80cm tall. I worked out , as I'm shite with number stuff, that no matter what way I join them, they will have still the 50cm width, but a 100mm length. As they only cost under £8quid a wardrobe, getting another two, and joining all together, will give 100mm length and width i.e. 1m squared. Already bought the black/white reflective lining, plus have enough mylar to ensure total coverage of reflective material. I also (I also have OCD and paranoia lol) bought polystyrene to insulate the cardboard before attaching the mylar. Now, and again apologies for not posting in relevant forums, as I'm pressed for time to return the lights..i.e. the dual 600, which I don't need, or all three for something smaller. Already got the dimmable digi ballast (refurbed from manufacturer choice of 200 400 or 600w), but need to know if I put all the boxes together to make a diy home made grow space, to accommodate four plants, do I need 600w lamps? I'll be going the blue and red phase hid's. Or should I get 400w lamps instead? Last but not least, can you point me in the direction of how to set up an extractor fan and ducting. Got the ducting and the filter, but looking at the online fans, I can't see how to connect them up. Recommendations on the cheapest, but decent quality fans would be appreciated, as this will be a full time activity, albeit on a small scale. My brain needs simple explanations, as due to some brain trauma, memory is shot, and I need childlike step by step instructions. A lot are advertised as inline fans, so I figure they are connected by ducting at one end, then attached to the filter at an exhaust port, but what about the intake? Is it simply a short piece of ducting material sucking in air? Or am I missing something? Finally, in a set up like this, what be the recommended intake intake fan? The filter is 4", a hefty piece of gear. Also, last one, I put four seeds in an electric propagator two days ago using a root riot pod, soaked in rain water then squeezed, surrounded by compost. One has germinated already. Should I now give them lighting, (they're in bedroom, so just get room light) I have a cfl 55watt doing nothing in particular, and could easily hang this over them... Sorry for all the questions....its just that Ive only three days left to request a return on the lamps, so input on that alone would be useful. As for the rest, you can redirect me to the proper forum. Being disabled (mentally and physically), basically, groups of people I avoid, or all people on certain days, but can walk to an extent, and move in short spaces, means I have full time to devote to learning about these little beauties, reading and watching, and it has given me a whole new Major interest. I could buy the finished project, but what prices they charge are galling, plus I could never enjoy it not knowing Exactly what it is.........I was only interested to this extent in motorbikes before, hence injuries, but this has been like an awakening. Again, my apologies for cramming so much into an intro post, but just need some guidance on the lamps. The rest, I'll read all your posts. But planted three peyote critical (photos) and a violator kush, but that got left out overnight after 24hours soaking, and i gave it a squeeze to make sure it wasn't fag ash, but planted now, but I might have fucked it. My trip to specsavers is long over due.
  4. Hi guys! Super excited to grow my own bud! Been reading this forum for a little while which has been very helpful but thought I would start my own topic for some personalized help. Right! So... I have just purchased my seeds (LowRyder #1 They didn't have and #2s) and tent which is a 60x60x140. I am now looking for recommendations for Lights, fans & filters. Once I get the whole setup sorted then I will then start looking into what soil, nutrients etc that i will need any recommendations on those would be amazing too! The budget for the lights, fans & filter is around £120 if that helps?! Light wise I would like to keep the heat/electric bill low don't fancy a knock on the door haha! Looking forward to talking with you (Supper excited for this, has took me 3years to convince the Girlfriend!!) and getting some answers! *Just to add I will be growing 1 plant maybe two but no more than that, Can you grow from start to finish with a full spec LED? I can also go more than 120 but that's a good starting point Cheers! JordySmoke
  5. I recently bought this grow tent and need advice on what else to buy, there are many bundles for sales with fans, lights etc but they are really expensive What would you recommend? All I have is the tent at the moment total newbie https://www.amazon.co.uk/Black-Orchid-Hydro-Hydroponic-80x80x160/dp/B01LYTASLZ/ref=sr_1_9?s=outdoors&ie=UTF8&qid=1530424769&sr=1-9&keywords=black+orchid+grow+room

We have put together an itinerary of the equipment we have gone for and think is necessary to get everything setup. This is now our final step before committing and spending alot of money on this, we would appreciate any feedback and advice from you guys, what do you think of the list? have we forgotten anything? would you change anything? reasons for changing any equipment? Any other valuable information?

  7. Hi all, im new to the forum and excited to be here, a friend @maverick40band I are looking to start up a personal grow and are looking for some good advice/ information, we are fed up with unreliable, poor quality or overpriced products out there and would like to have a clean tasty reliable source of our own. At the moment we are completely undecided on the best way to set up our tent. Hydroponics or soil grow? Potsizes? Light types? Fan/ extractor sizes? Nutrients? We are looking at a 1.2 x 1.2 x 2.4 tent and would like to grow 8 plants, is this tent adequate for the quantity and if so what equipment is needed to setup the tent to achieve a perfect grow environment? We do have some ideas of our own but would like some fresh ideas from experienced growers to compare notes and to see if we are on the right lines. I won't tell you what we have in mind as i feel we will benefit more from the knowledge and experience of this forum. Any advice on the equipment you would recommend, what and where to buy from, things often not thought about when setting up, recommendations on soil or hydroponics (pros and cons), or just any information you would like to share would be greatly appreciated. We are fairly new to this, we have a couple of 1-2 plant grows under our belts, so we are looking for as much knowledge as possible. Thanks for taking the time to read my post and I look forward to hearing from you all.

    hi guys can someone plz help ive recently wired up a twin variac fan controller, had some major issues at the start but rebuilt it from strach using a multi-meter testing as i go.. now i think ive sussed it but my variacs after time just continue to get hotter and hotter i turned them off when they reached 35C... i think they are wired correctly ive check various threads on here and it seems all good checked it with the multi-meter reads what it should when it should... now i did arc the variacs early one (school boy error very high) could this have damaged them to cause this... ive not earthed the variac themselves ive seen a few people commenting on here but it doesnt appear in any of the steps or photos??? i have netural to a output live e input live c the netural runs straight into the rely then branching off to the atc800+, variacs & neutral out to the fans
  9. Looks like I might have a stroke of luck with a friend in need that will be living in one of my spare rooms temporarily. Just had my annual gas check done and signed off, so should be safe to get a grow on. My friend has a 7 ft x 7 ft tent and some experience growing. I know that it's in his interests to keep things quiet. He is a very private person with a healthy amount of paranoia, for a good reason. I was originally wanting to set up inside the house, but my friend noticed I have a large garage that was bricked up years ago (now basically a large outbuilding) He seems to think this would be a better idea. I'm not so sure, it would mean having to have electricity and sockets wired in there, so there are extra costs straight away. I know there are fans that run almost silently, but I'm worried about my neighbours noticing anything suspicious. I used to let them use my garden as a way through when they were doing some work in their own garden and also to let them in my shed to borrow the odd gardening tool. I've started locking my shed door now and want to cool things off with them a bit as they have pissed me off a bit lately. Won't bore you all with the reasons why Wanting to grow in as natural medium as possible and was wondering what the optimum number of plants would be in the 7 x 7? Also what lighting, extractor and fan size I would need? Many thanks in advance. I would take the time to read up more, but have an illness which has got worse over the years that leaves me easily fatigued and causes problems with my vision when reading/trying to concentrate
  10. Hi There, Been studying how to do an indoor grow for ages saved up a bit of cash and have decided to go for it. So first grow is about to start Bubble Kush Auto seeds arriving tomorrow. So first thing first the room specs. DR60 Secret Jardin tent (small i know but its the only space i got) 1 x P150 PLATINUM LED 2X 2FT Full spectrum fluoros attached vertically in rear corners facing it 1x 4 inch fan and carbon filter with ducting pulling hot air out. 1x six-inch desk top fan for air movement in tent. 1 x exhale co2 bag (i know its not necessary but inquisitiveness got the better of me) Will be growing in soil - start with bio-bizz light with added ecothrive charge , nutrients will be bio grow , bloom etc. Been running tent for 2 days now empty to get the environment right Temps range from 20 - 28 degrees ( high temp is with all lights on and in bloom mode) i think the fluoros are a bit overkill but potentially good for vegging turn them off when switch to bloom. have extraction fan come on for 15 minutes every 15 so could even run it constantly to get temp down. humidity is averaging 56% Any way question with the C02 BAG instead of the exhaust just dumping the warm air out side wasting the co2 was thinking can i recycyle the exhuast back into the inlet thus sealing the room kinda, maybe even put another 4-inch fan on the inlet to move air abit quicker thus cooling it ? DO you think this is the right thing to do to use as much of that c02 as possible ?
  11. I have a friend who is doing their first legal grow in America, however his internet has crashed so he has contacted me to try and find a solution. The Problem is heat! It is a stealth cabinet grow currently with a 125w dual spectrum for 2 plants in 5l pots. They understand that this might not be the best set up but its what they have. Apparently temps usually sit around 85'F or 29.5'C which is quite hot on its own but temps have reached 111'F or 44'C on the odd occasion. The temps are being measured at the average height of the plant, Apparently they are around 2 weeks old (from sprouting) and are an autoflower strain. They haven't browned or discolored and are still a health green and growing daily, however some of the leaves are curling up at the edges and some apparently seem to be almost spiraling around ( not curling under but twisting sideways) not massively but a little. There are 2 80mm PC fans ,one intake and one outtake, which more than cover the cfm needed for the space. So what do you think he should do to reduce the temps? Add two more PC Fans? Also if they were do do this, roughly speaking one fan is in a bottom corner and the other is in the opposite top corner, would the two extra fans if they were to be attached on the opposite side of the cabinet be placed so that the intake are both at the front and outake both at the back or so that both intakes are say bottom right on each side, so from the front one would be near the front and one near the back? Add a PC fan inside to increase circulation? Reduce light hours as they are currently running 20/4 - 20 on and 4 off Also can anyone recommend any threads about building scrubbers/ carbon filters? Would a carbon cooker hood filter work? As apparently it has started smelling not of full flower but a smell they would like to remove. Thanks in advance for any replies!
  12. Hi, looking for a bit of help I have been slowly building my grow rooms up my loft It is a bit of an annoying shape with the trusses going across but I have just built around them I have insulated the rafters using foil bubble insulation then built my rooms from 50mm celotex, hopefully this will be enough to keep a stable environment. I have a bit of an idea of how I want to kit out the rooms but obviously with very little experience ( I had a small drobe about 8 years ago, which wasn't very successful) I am not sure if it will all work or it is the best choice I only want to do this once and do it right.. I am hoping this is were the knowledge of UK420 will come and help Anyway onto the rooms, still need to finally seal them all up and put some liner down on the floors then figure away to stick some mylar to the walls Excuse the mess ( and the roughness ) it is still a work in progress Flowering room at the back and veg room to the left. I have a space to the left of the flowering room that I am going to use for a drying room, but this requires some more work. Flowering Room The dimensions are 118cm deep and 167cm wide Height is 195cm at the peak and 160cm at its lowest I want to run a light in between each of the trusses to allow the best light spread I am hoping for two 600w ? not sure if this will be to much and I would need to go with two 400w ? Hopefully I have the height to get away with 600w ? Fan size I have absolutely no idea, I understand I need a good sized fan to cope with the light and for the extra temps that loft growing brings. Noise is a concern as well, I basically don't want to hear it at all when the hatch is shut at the dead of night when it is silent in the house (and the neighbours) I am not sure if I can do this RVK`s in a box and acoustic ducting ? or do I need to be looking at quieter fans ? They will be connected up to a speed controller whether I build one or buy one I haven't decided yet Veg/Clone/Mum Room The dimensions are 118cm deep and 105cm wide Height is 160cm at its highest and 81cm at its lowest I have 51cm either side of the trusses Light wise for here initially I am planning on two 2ft T5`s for seedlings and clones Not sure on the light spread of the T5`s so would I need the 4 tube or could I use the 2 tube ? Once they have grown up a bit I am wanting to change the lights out for a hps / mh to veg them until they are ready to go into there final pots in the flowering room. not sure on the wattage I need to go for here and again fan size, which I suppose will depend on what wattage of light I want to run. Looking to get everything ordered up asap so I can get up and running, all ready picked up some physosister and no names during the ugorg 420 offer cant wait to give them a try Any help is well appreciated
  13. now then people looking for some shopping advice. looking to buy a new extractor fan and filter already know i'm getting a 5" rhino filter 125mm x 300mm. i've got 1.2m x1.2m x2.0m tent i'm hoping that a 5" fan and filter should be sound. so gone to my locle and got a couple of choices in terms of fans this is what i got to choose from rvk fans tt fans vk fans wk pro fans vko fans max fan pro rhino twin fan ram fans hctt powered fans so there the choices not sure which is the best for the space i've got cheers for any input
  14. We all put up with them or endure them at some point, it's not like indoor cultivation started yesterday, is the the best alternative? they are all pretty much the same I don't care what brand name they printed on them. Is this the usual British trait of :- this is what we have always used, there not the best but they do the job? I'm sure they were not designed for the extensive use that indoor garden demands. An oscillating axial fan would be more up to the task in my book, anyways I've searched every where for a specifically designed fan but can only find the "same old" with different names claiming they are the best. Is there anyone out there that can point me in the right direction of decent alternative please, (not towers) or am I fanning up the wrong tree and dreaming of the perfect world again.
  15. Hello Again My Friends, I wonder if any of you have had any experience with acoustic fans? I've tried Ruck Box acoustic fans they seemed to work to a degree, I just was thinking perhaps some of you may have had experience of using different brands and could tell me if there's anything quieter they would recommend? Thanks BR
  16. Well it's hot again today and, while I've already got control of my temps, I'd love some 420 peer reviewed advice! So, I've got the following setup : 2 TentsMother/Clone Tent (M)​Using T5s Flower Tent (F) 2 FansRVK 125 Low Power Rhino 150 High Power 1 CF - in (F) 1 Extracted Reflector - in (F) 1 Primair In/Out fan controller 2 Intakes from outside Loads of Ducting Acoustic & NormalSo much my house looks like a scene from Brazil! Initially, I ran them as 2 separate air flows / systems; (M) had a passive in and the 125 RVK extracting; 150 Rhino was extracting (F) and it too had a passive intake. This setup worked fine - that's to say the temperatures are easy to control, albeit manually, through the min/idle speeds on the primair. However, because they are separate systems I was a little reluctant to rely on the primair's temperature sensor to automatically adjust the fan speeds. So on hot days, like this morning, I have to manually adjust the min/idle speeds to increase the extraction and keep the temperatures down. In the hope of automating the speeds, I've connected them into a single system: Exhausted of (M) is now connected to the in of (F) Only been connected for 48 hours and I think I've almost found the sweet spot in the (F) tent to position the sensor & the temperature setting for the primair. So if I've got the temps sorted, what am I asking? Well I'd like some feed back on the whole idea of using the Mother tent's exhaust as an in for the Flower tent? Also the exact arrangement of how I use the 2 intake from outside with the fan and the ducting. Time for a little diagram or 2... Here's the current configuration: | OUTSIDE | =====V==========================V========= | | | | | ----->-----Y ---V--- ^ | | | 125 | | | (M) >---->@-->- ------V------ | | | | ------- 150 | (F) | -<----@<----| | ------------- Note how I've positioned the 125 RVK fan before the intake from outside that feeds the Flower tent. Idea being, the flower's 150 fan is much more powerful and so, when required, draws additional fresh air from both intakes. But I'm no Air flow / aerodynamics expert so was a touch concerned the Y piece will allow for the flow air to push fresh air back-out. It appears that it doesn't, but is there anything I should be aware of if I'm using this configuration? An alternative layout I'm considering is the following: | OUTSIDE | =====V==========================V========= | | | | | ----->-----Y ---V--- ^ | | | | 125 | (M) >-------->- @ | | | ------- ------V------ | | 150 | (F) | -<----@<----| | ------------- Note how the 125 is now AFTER the Y piece. I'm worried this might cause the insufficient air to be extracted from the mother, guess I'll have to suck it and see! Has anyone tried this setup before and have any advice? Or can you suggest any other arrangements that would be worth trying?
  17. fans

    Cant get my temps down, got intake and exhaust fan providing over 100 air changes per hour, but cannot get temp below 30C. What else can I do?
  18. Morning everyone There's a few threads on here about the Ecotechnics Fan Controller but I thought I'd start my own I was looking at fan controllers for ages when @@Jiffa recommended the Ecotechnics, I was a bit dubious as I had read loads of reports of this controller making fans hum and actually creating more hassle than they were saving. Well I've had it a little while now and I have to say I'm super impressed. I have an 8" TD silent for extraction and a 6" TD Silent as my active intake and I have a 1000w Halogen heater at the end of my intake. You can controll just about everything you need from one controller. My temp is set to 20 degrees and I can even set how many degrees above this when my heater goes off. I've currently got it set to + 2 degrees so when it hits 22 it will turn the heater back off giving me great control over environment and costs. You can also set your max temp so fans increase to bring it back into range. You can also set your max fan speed which is great if you need to keep noise below a certain level, I have mine set to Max 80% (I know my fan can deal with temps at 80%) which means in the summer my fans won't sound like a jet engine if temps are to high. You can also switch the lights off on the controller to prevent lights interfering with your dark cycle should you want to place the controller in your tent. I've had no issues with fans humming, I can only say this for my setup though. Another good point about this controller is the amount of sockets it saves me. I have my extraction, intake and heater all ran by the one plug to the controller, great if your short of sockets like I am in my garage. One of the reasons I fancied this controller over others is the heater option, really does give you total environment control. So it's a big thumbs up from me, get them setup correctly and they completely manage your environment for you. Cheers T, x
  19. Hi people, im very new to this but with a lot of research and forum reading ive set myself up with some equipment, some nutrients and a 1.2, 1.2, 2.0 grow tent. Firstly I wanted some help with any ideas regarding extraction and a velux window, the window has a blind shutter on it but Icant just put my pipes out the window or near it, I was thinking of fitting my pipes to a box and placing the box below the window as there is a window sill would this be a good idea and has anyone had any eperience with blowing out of a velux window and keeping it well hidden. Secondly. My fans There basic filter kit fans, not rvk fans just basic fans I have one which came with the filter and one I bought from ebay seperately, I know there both over 300cfm and I know they wont last long but I was wondering if they could handle a 600watt cool tube set up, its difficult getting an idea with no grows under my belt, I understand im better blowing through a cooltube possibly so the fan isnt getting as hot as sucking but can I go ahead with that kind of set up, obviously ill be running the filter on a seperate fan and extracting and the cool tube from a cold room and blowing out the same velux window. Any help would be greatly appreciated, Cheers
  20. Hi guys, It's my first grow and I'm in first week of veg, I think ha ha. Basically I'm trying to find out whether my airflow set-up is correct. So here's what I got..... 6 plants in a 1.2 x 1.2 x 2.0m tent, growing in coco under a 600w hps. I have a 4" intake at 187m3/hr or 110cfm and a 5" outtake at 280m3/hr or 164cfm ( i think conversions are correct) Will the above fans provide with correct air exchanges? My temps are currently around 26/27 celsius, humidity is on the floor, the digital meter just has 2 horizontal lines on it which I assume means zero . Struggling to get my head around the airflow and the only examples I can find on the web are for completely different/more advanced set-ups. I've always been a believer that anybody can learn anything - if you can't understand something then it may be because somebody isn't explaining it in the right way. Can anybody give me a quick tutorial that is easy to understand......? Many thanks in advance
  21. Okay, first of all I would like to welcome everyone, as im a newbie in growing. My budget is £200 I planning on making a small tent, with a light . I am about to do SOIL and not hydroponics. What my problem is, I couldn't find a decent AND cheap fan for this. My friend told me, to buy a PC power supply and a few PC fans, place them in the right orientation and it will make in/out airflow, still being cheap. So the tent will cost me £60, the light will be the same~. So out of 80£, I gotta buy the seeds(10-12£ each) I want TWO plants, both auto-flowering and fans. I think I can get the earth etc easily. I cannot do HPS lights, neither I want. I like CFL lights and they don't overheat, neither CFLs need a ballast. So, I would like to take suggestions, what are you guys think? Any advices before I buy all of these in once? More specially, about how to get the fans right. Would be awesome, if you give me links where I can get the fans/stuff you are telling me about. I would prefer only UK sites. Sorry for the bad english, trying my best. Please be sensitive, thats my first grow and would like to have some decent buds from it. Cheers
  22. grow room 60cm x 60cm x 160 cm 3pots inside 9L each. 1 autoflowering : chocolate heaven <-----attitude seed bank 1 autoflowering : cheese auto <-----attitude seed bank 1 Arjan Haze #3 <-----greenhouseseeds 1 HPS 400 Watt 2 Cfl 13 Watt Each I had them first 2 weeks under the Cfl's and 1 week now running under Hps.I had the lights run 18/6 but because of the fans noise i changed the light cycle to 16/8. 2 fans installed.One sucking inside , one extracting.The one which is for extracting is connected to the cooltube and because it makes a lot of noise i close it at night. The sucking fan runs for 18 hours in this stage and when i see buds i will change it to 24 hours to have nice air flow to prevent mold. I would like to know your opinion about the light schedule and about the fans.I will try to upload some pictures tommorow so you can have a better view of my growroom.
