  1. All my autos are flowering now. One, a critical banana smoothie from taste budz is already done. All my filtered spaces are full though. I had to move a sweet berry cough into the area I was going to dry in as it’s almost the same height as me. I don’t know what plant is what, I had written it on the pots but it’s seems to have rubbed off. I had a few watermelon punch in there so I think I can tell them apart. Other than that there is a gelato and a back to the future 2. it’s like opening a tent door to Christmas
  2. 4 Weeks 1.5l Pots Subbie Seeds

    From the album UGORG, UK420 Subbie Seeds Coco Grow

    1 month on from seed. Plan to whittle these numbers down considerably once the females show. Holding off topping for now in the hope they tell me sooner.
  3. Survived 3 Hot Nights Alone Hurray!

    From the album UGORG, UK420 Subbie Seeds Coco Grow

    Have dialled lights to 240W (375W fixtures) since thought they looked a bit under the cosh and maybe light too intense.
  4. Seedlings Under LED

  5. Hi i have three vero 29s hooked up to my mw hlg240h. When I soldered the chips I got a little problem with easily covering the top of he wire with tin, the bottom usually made contact and sticks. The thing is some of my cobs light up correctly and glow like little suns but some of the cobs have like a line on them which is not lighting up,but on other it does. What might be the cause of ti and possible way to fix it please?
  6. Atreum Hydra 1000 LED grow light - UK Full-spectrum 100w LED grow light samsung meanwell driver 2.7 https://ledgrowlights.co.uk/collections/atreum-lighting/products/atreum-hydra-1000 Atreum Hydra 1000 LED grow light Hope everyone's liking the new site and our new ranges... We're very pleased to be working once more with Atreum Lighting as they release this fantastic little 100W board (that we fell in love with the moment we saw). Not only does it have a unique OLED display showing exact wattage being consumed, but as you can see the diodes have been spaced so they provide a really nice, even spread. An all-round cracking little light for many applications really. We did some PAR testing in a 50cm x 50cm area, have a ganders. Migro did a nice video showing off this light. Well worth checking out, but bear in mind that it does in-fact have a conformal coating (making the boards water resistant), contrary to what's said.

    Such hope in the air! Let's fill this tent!
  8. Lights On Action

    From the album UGORG, UK420 Subbie Seeds Coco Grow

    None of my purple Jamaican bag seed germinated and a few Footloose never made it. The subbies seeds had a 100% germination and although I know the Footloose will be good the Psychosis x Animal Stomper and Smile x Blues has got me really excited. Potted on seedling pots and fed with 2ml Growers Ark root tonic, 1ml Grow A&B. Lights are Scope version 1 375W fixtures. Dialled down to 280W gives 300umols at 100cm. Must remember to be really careful with overdoing the LEDs...
  9. Diy led lights (F series strips) T his is a diy thread, for the diy guys, to diy a diy led grow light..Its the cheapest way to get a decent led light. Im not going to get too deep here. This is a basic guide with parts list with product codes to google, rather than a how to build it.. “what wattage do I need for my space” Strips. The Samsung f series strip. This features 144 Lm561C S6 bin leds. Driving them at the currents listed in the parts lists will achieve 2.2-2.35 ish µMol/j at system level. Warning! Don’t be fooled by the cheaper boards/strips.Genuine strips have the Samsung logo and are fully CE compliant. Heres the parts numbers for the strips.Google will give you the supplier. 3000K SI-B8V521560WW 3500K SI-B8U521560WW 4000K SI-B8T521560WW 3000k and 3500k will do veg and flower for weed, just buy whatever’s in stock. 4000k might be useful for mums or lettuce, micro greens etc Strips cost £28 each or you can get a discount on ten+ (including vat which they will add at the checkout) Drivers are easy to find, again just google the part number in the lists. TME is the best place to get them. Ill put rough prices so you know whats the right price to pay. heatsinks you want U channel aluminium. 1 3/4” wide 1” high and 590mm long. This is a very common size and easy to get. Framework you want 1/2” by 1” Unequal aluminium angle(Or whatever you can get. staiir nosing work great). For the length you need it a little smaller than your tent. So 60cm tent get 40cm angle. 1.2m tent get 1m angle. Just get it as big as possible.If your tent is 1.2m or bigger build it in two lights. Max spread is the game here. More points/angles of light over the area = “penetration”. The metal work you can buy cut to order online, or a local shop will do you it cheaper. Heat sinks cost around £4-5 each and framework is a couple quid. All the wiring/wagos/bolts ect be found easy on shitbay/scamazon. Or any local electrics shop. Make sure you get solid core wire. And your power cable is a 10amp one. Are you still here? Heres a chart, I think it makes sense Heres a list just in-case it doesn't. Prices are the max you want to pay really, you should get it a bit less if you get the metal cheap. . 150w. Total cost - 130ish l 2x F series strips. l 1x HLG-120H-48A driver (£40 max) l 2x heatsinks l 2x unequal angle. l 2m 18awg or 20awg solid core wire. l 2x 3 way wago connector. l Old kettle lead for the plug. l 3 core cable connector. l 20mm thermal tape roll l Bolts/nuts/rivets (whatever you want to use) 210w. Total cost - 170ish l 3x F series strips. l 1x HLG-185H-48A driver (£45 max) l 3x heatsinks l 2x unequal angle. l 3m 18awg or 20awg solid core wire. l 2x 5 way wago connector. l Old kettle lead for the plug. l 3 core cable connector. l 20mm thermal tape roll. l Bolts/nuts/rivets (whatever you want to use) 265w. Total cost 220ish l 4x F series strips. l 1x HLG-240H-48A driver (£55 max) l 4x heatsinks l 2x unequal angle. l 4m 18awg or 20awg solid core wire. l 2x 5 way wago connector. l Old kettle lead for the plug. l 3 core cable connector. l 20mm thermal tape roll. l Bolts/nuts/rivets (whatever you want to use) 350w. Total cost 280 ish l 5x F series strips. l 1x HLG-320H-48A driver (£80 max) l 5x heatsinks l 2x unequal angle. l 5m 18awg or 20awg solid core wire. l 2x 6 way terminal block l Old kettle lead for the plug. l 3 core cable connector. l 20mm thermal tape roll. l Bolts/nuts/rivets (whatever you want to use) 420w. Total cost 340 ish l 210w kit parts x2. 530w Total cost 440 ish l 265w kits parts x2. 700w Total cost 520 ish l 350w kit parts x2. The build its self is self explanatory really. Mount the strips last so you don’t damage them. Get the tape lined up right before sticking it as it WILL NOT come off once on. Wiring is the only tricky bit. Its a parallel wired system. All negatives from the strips go the the negative on the driver and all positives from the strips go to the positive on the driver. Here a quick paint wiring diagram, to show how to do it. I don’t mind helping out, if you have a question, just post it on the thread. It is a low voltage system (47V) but still be careful, take time stripping wires right, cable tie them to the frame. If you can see any exposed core you have fucked it, try again. DISCLAIMER- key accepts no responsibility for damage caused to persons, or property. This is not electrical advise, just a parts guide. Don’t pm me asking where to get stuff , post questions in this thread. PMs will be ignored. @mods Any issues with this please let me know.
  10. Alright folks! Hope this finds you well! So awhile back the good people at Dutch Passion @DutchPassionTony gifted me some auto seeds to run, I usually do a few autos over the winter as its easier to leave the lights on that faff about with heaters etc.. So here's what they generously sent me, So first I prepped some pots, once again I'm reusing the ecothrive soul, broken up and recharged with some plant life cycle and charge, like so.. These were left to sit a few weeks before I put a few seeds into soak, After an overnight soak I popped them into some jiffy plugs and stuck em under the T5 to sprout, 12ish hours later we have life! Once all 3 had chucked there shells and had leaves out they were transferred to the 12/15(i forget) L fabric pots and placed upstairs in the veg tent under the 4000k Sammy strips on top of a heated blanket, Excuse the crap pictures, new phone/camera and still learning.. Anyway a few days later, Now 4000k strips are great for veg but I figured something more appropriate for flowering would be necessary, with that in mind I took out 2 of the strips and replaced with 3 x qx75w boards supplied by our fantastic sponsor @diyleduk these boards are full spectrum with more deep and far red in the mix, So 1 75w board per plant plus a bit of crossover light from the strips, the boards are on a separate 185w driver so slightly under run, I may upgrade that later.. Here are the girls yesterday, If they look a little sad it's coz the temps in the loft have bottomed out these past few days but I have a plan to remedy that (a dodgee one not the cunning sort). Anyways if you got this far thanks for reading! As always looks/laffs/bantz is what this diary is all about and hopefully showcasing some amazing new genetics from our friends at Dutch Passion. Please feel.free to steer me right when I appear to be going wrong! It will happen! Thanks for looking, nice1 ta
  11. Hello all, I've currently got 2 monsters growing well in DWC. My current light is Viaspar 450w. As the plants exploded in growth quicker than expected in the late veg state, and are now in the early stages of blooming (flowering has started), I've upgraded to a bigger tent for both height, width, and climate control. The current (new) tent is 1000x1000x180. I purchased a new Marshydro TS1000 with the new tent. My big question is, should I change the lighting in the new tent to the TS1000 or keep growing this batch under the Viaspar 450 lights, as that is what they are used to. The current light distance is around 40cm and growth has stabilized. I don't want to shock them at this point with a 550w light spike if it will be a danger to them. Even if this new spectrum will be better for harvest. Does anyone know anything about switching lights at this stage? This is my first hydro grow and everything has gone great so far (except for the late veg growth spurt) and I don't want to fuck things up for them in the last stages Any input would be really appreciated!
  12. Hi everyone, first run is well underway with some second hand Mars hydro TS2000w leds absolutely love them they’ve outdone themselves for the price I paid. They are 350w each and as said so far I’m very happy. I’m currently in week 2 of flower. for my next run I’d like to upgrade my lights to something more substantial.. my grow tent is a 2.4m x 1.2m footprint. the two contenders I’ve narrowed it down to are: 2 x Mars hydro FC4800 (480w) or The slightly more expensive option 2 x lumatek zeus 600w pros. both look great lights and if the TS2000’s are anything to go by then the fc4800 will be great. im just trying to work out of the lumateks are worth the extra pennies. any advice is appreciated cheers guys
  13. Welcome growers.. This is my micro grow in the shed stealth style! (Attempt) I've been growing outdoors in the UK for the last 5 years with only a cabinet to get my seedlings going. Done the odd seed to harvest with CFLs but nothing special. Then I came across the QX-75 LED board from @diyleduk which looked made to measure for my cabinet and ideal for temps being in the shed. Never using an led before excited to get going was a understatement. Yesterday I received my QX-75 LED through the door from @diyleduk and it's obvious these lights are miles above anything iv seen before for light output to wattage! On full power 75w is crazy bright! Couldn't believe how bright it was. Would like to say a massive thank you to Adam for sorting it out! The light QX-75 Each QX board has 128 leds in total. 120x LM301H (3500k) 6x LM351H (660nm deep red) 2x (730nm far red) And looks pretty The driver has a nice length of cable to reach outside my cabinet and the dimmer switch is a very easy way to adjust wattage The cabinet I decided the cabinet needed upgrading ready for the new light to give me the best chance possible.. Dimensions, 35x35x80cm I put a mini tube heater in and usb fan to help control temps. Then decided I know longer like access from the side. Swapped set up around so I could get to the plants from the front. Both pc fans have acoustic ducting attached. The bottom one bringing in air through the bottom of the shed The top one is connected to my 4" rvk fan that's boxed in for silence sitting on a rhino carbon filter. I then insulted the cabinet.. I put the inkbird probe under shade from the light. Attached a wac1 step controller to my 4" rvk to reduce noise further. Then yesterday I got to do the exciting part.. getting the light in and set up
  14. ThinkGrow Mode-I Full Spectrum LED Grow light We're the first ones in the country to get our hands on this very nicely built LED fixture, from ThinkGrow. Extremely compact for 720 watts and at a very reasonable price, this lamp kicks out 1829µmol/s at 2.54 µmol/j and has a specially designed V-shape panel in which the LEDs are mounted. This widens the total beam-angle provided by the diodes, allowing for closer hanging than HPS - similar to strip fixtures but with a much smaller form-factor (just 11cm wide) - making this light ideal for multi-fixture applications in larger spaces. Fully compatible with TrolMaster. controller, waterproof (IP66) and 5 year warranty. https://ledgrowlights.co.uk/collections/thinkgrow-led-grow-lights/products/thinkgrow-model-i Currently £945.95 We'll get some PAR testing done for this as soon as we're over this current busy period.

Spider Farmer LED grow lights Full-spectrum 100w 200w 400w 700w LED grow light samsung meanwell driver spider farmer https://ledgrowlights.co.uk/collections/spider-farmer-led-grow-lights I've been impressed by the quality of the current Spider Farmer LED's on offer and thought they would be a nice budget option to the range we're putting together.

  17. Telos LED grow light bundle Full specrum led grow light uk made meanwell driver https://ledgrowlights.co.uk/collections/telos-led-grow-lights/products/telos-10-pro-led-grow-light-bundle It's no secret here how much we love the Telos Pro range. The quality is just second to none.... To make things easier for customers wanting to use more than just a single unit, we've put together a neat little bundle. They're incredibly powerful for the wattage and give really good spread when multiple units are used and spaced out appropriately. 9 x Telos 10 Pro in 3 x 3m area: Two of these in a 1.2m tent uses only 570 watts at the wall and as you can see, even when hung at 25 inches it's putting out some serious intensity. Now, for some people used to using 1000W HPS in this space, this would be an exceptional replacement. Bit too intense for most people in this space though. 1m x 2m is personally where I think these would do best.
  18. Hi. I see Samsung now produce a horticultural range of LED strips called L2. Anyone tried them yet? They use the white LED's around the (4990K ~ 5820K) range, and have added red diodes. Pretty sure they use the same drivers as the older strips (3000k etc) £31 each for the 58cm strips. Here's them in action on a custom U.S. made LED rig: Which retails for around $900 US, but could be made for around £400 from Digikey and some DIY. 8 strips is over kill but those numbers are pretty amazing. Looks cool, just wondered if they were as good as they claim to be. E2A: Parts number at Digikey is: ‎SL-B8R5C9H2AWW‎
  19. I want to order lights from MARS HYDRO but theres two sites. EU and UK. EU iis cheaper but do they give an UK plug automatically? Also are they legit? I want to buy the TS600W its got great price and it's just what I need.
  20. Once more unto the breach.. Come one, come all and join me on this wintery auto adventure. Firstly, I'd like to say a big thank you to the Sweet Seeds guys for sorting me out the seeds to compete. Hopefully this becomes a diary to be proud of. Now, when I first joined this forum I trawled through diaries expanding my knowledge and found Sweet Seeds kept popping up! So I focused in on SS diaries and came across @McHazy's competition diary! "McHazy's Quest for a Sweet Seeds Grinder" (Think of this as a tribute ). Which intrigued me; how special can a grinder be ? Needless to say it's an elusive cop &Winning it certainly adds to the mysticism of it. Since then I've found myself longing for it, my tattered old grinder seemed to do the trick, before I found out about the SS grinder.. Now onto what we're all here for! The Lineup My official, final lineup for the competition is: Cream Caramel auto, Cream Mandarine auto & Blackjack auto The Setup 60x60x140 tent (soon to be a 75x75x200) 4" extraction/filter (RAM/Rhino) Passive intake 1' Tube heater (hopefully that'll cut it ) Biobizz AllMix Biobizz Grow/Bloom 9L fabric pots Considering this is only my 3rd grow and 1st attempt through the winter, I'm not very prepared for what I'm about to face. It's also safe to say I've got next to NO IDEA what I'm doing! BUT HEY-HO IT IS WHAT IT IS. Thanks for stopping by! P&L Flav

  22. Welcome to my new grow..... I'm on a mission this time. My Landlord is about to start building a new house next to ours, so we have lost our privacy We are definitely gonna move out in the next month or so, and supplies are running low, so I wanna grow some strains that I know can deliver a sizable harvest so we can move halfway through and get a good result. Right off the bat, I'm gonna do a Daiquiri Lime.... consistently a winner as I managed half a kilo last time I grew her. Toofless Alien did well last time, and I really love smoking Night Queen (my last seed). So on 26th June, I put up the tent, and made up three 20L airpots with H&G Coco and soaked them in a EC 0.6 nute mix. I planted the seeds and covered the pots with cling film and some dark card, leaving them under a couple of Skyline 400Ws for warmth. I didn't have quite enough coco (as always) so I ordered some more to top up the pots in a week or two. The seedlings sprouted on the 28th 29th and 30th.... Toofless Alien first, then Night Queen, then the Daiquiri. Here they are on day 5/4/3.... Then the new Coco arrived, so I topped up the pots, and thought I may as well fill another airpot up and plant a new Think Different from the batch of seeds I won from AFN. I also received a new Skyline 400W unit (thanks Mate!) so I had my 3 seedlings under a Skyline each, while I waited for the TD to sprout. She eventually showed her head on the 10th June, 12 days after the Alien.... so a bit of nute juggling will be going on these next few months! Here they are now..... Toofless Alien day 17 she really is flying away! Night Queen day 16 looking really good and healthy. Daiquiri Lime day 15 she started sluggishly and has now picked up. She did this before, so no worries They older ones are on an EC 0.8 nute mix and the TD is on EC 0.7. Think Different day 4 early days yet! I have now put a Photon 126 over the TD. She should take off! Hope you enjoy following this grow, more updates on the way!
  23. Hey 420 Can anybody give me advice regarding hanging heights with Zeus pro for veg & flower. it recommends 18 - 24” on @diyleduk but is this at full power? if so, could you half the hanging height and half the power e.g 10” at 50% power.... making more efficient on electricity etc. I’ve currently got mine in early veg at 19” from canopy at 75% power. Growth seems ok but They’re only a week old from rooted clone. I’m not sure if they could do with more or if I’m giving them too much... My lux meter is reading around 30,000 in the middle but it advises on the net optimal veg is 15,000 - 50,000 any help much appreciated guys!! thanks
  24. Easy all I've got some issues happening on one of my plants that I can't work out the cause. There's two plants in my tent at the mo, and one of them is doing a lot better than the other, although I can't how there is much different between them - they are both in the same pot of living soil (think it's about 80 ish litres, I made by connecting together 3 airpots so not sure of exact size). I think my first guess was light burn, but the leaves should start praying rather than drooping if so? The light is pretty powerful though and I've not really got it up to 100% yet (Lumatek Zeus 600w). Also I think the problem got a bit worse when I did try it on 100% for half a day recently. I've also been considering under/over watering, which fits with the drooping leaves but not sure if it fits with the discolouration on the edges? The soil seems a bit on the dry side at times recently but it's hard to tell properly as it's now dense with roots and I can't get my fingers in there properly to check it out anymore. I've measured it with one of the £4 moisture/PH meters on sticks you can get from B&Q, and it doesn't seem too bad, at times a bit too wet and at other times a little too dry. Not massively so, but I don't know how accurate those things are at measuring it. I'm mainly watering with blumats, which I'm still fiddling with quite a lot, probably not helping the situation... Finally I've been considering wind burn too, as the damage does seem to be nearest the fans in the tent, vaguely anyway. But the leaves have been barely moving, just a tickle really. The fan wasn't ever pointed directly at the plants, and the branches definitely were nowhere near swaying, so I doubt the air movement has been too strong really. I have seen some fungus gnats from time to time, but only one recently, and that wasn't actually inside the tent but in the room the tent is in. There's a shit load of rove beetles in the pot though, and earlier in the cycle it was also treated with nematodes and hypoaspis miles (I got a bit of a thing about fungus gnats a couple of months ago... probably didn't need to worry so much to be honest but I've got a colony of rove beetles now thanks to @FarmerPalmersNT's post on the subject so I'm not expecting to have much trouble from them really. Environment has been a work in progress, lights on temps are around 28c ish, and RH is around 45% now. I think the humidity is rising to 85% at some points though according to my hydrometer , presumably just after lights off (not entirely sure I trust the readings from this, it's pretty old and the external probe has defo conked it). Min temp is showing around 21c. So not great... but I can't afford to buy/run a humidifier or any other heating gear really so I'm hoping for the best like this... I'm a proper beginner in case you couldn't tell so any pointers will be greatly appreciated. I'm gonna get a grow diary going at some point as it sounds like the best way to receive advice, but not able to do that just yet. Cheers!
  25. Hi lads did someone attempted to wire drivers safely outside the box for better cooling ? Im curious if it can be done safely. My setup involves arctic 64 plus fans, vero 29s and some hlg 240h /2100 b. I have pretty weird box design and would like to use metal shelf rack inside the box as a construction that would allow me to split the box into two separate storeys. first would be veg second bloom. The light isolation would not be an issue, but I want to avoid electrocuting myself so I would like to learn how those cobs are grounded or if only driver needs to be grounded. here is a noobie diagram of what I have and want to do : https://imgur.com/ZvkSX8U I would be very happy if you share your thoughts with me about this, my original thought was using one storey lighted up during the day and other during the night ( with light isolation between them, so one would have light and other darkness.
