Hi! Everybody talk about pound but we should talk in gpw!!! Gpw is a good scale but there is so many factor we should take in consideration! First vegg time: you can't compare a grow with 4 weeks vegg and one with 2 or 3 month vegg! Second CO2 same you can't compare a grow with and without...

Thanks!!!...but I need proof! A grow log would be great...i know lm/w is not the best way to compare light but it help a lot! What I am looking for is gpw (and quality of course but quality is not 100% related to lights) the best light for me is the one who grow the highest gpw! So which led are...

You are welcome! You know I am a crazy French grower who believe we are a big family! What kind of driver do you have!? 21w each is pretty high for young plants so you can stay like this for 2 weeks before start to increase intensity! You will know when you will need more light! Have a lifted one

Hi! Do you have your light at minimum intensity!?? Young plants do not need a lot of light! Just adjust intensity to minimum and then adjust the distance between plant and led! Add 10% more light every 4/5 days! Have a lifted one

Hi! 31°C is about 90°F!

Hi! If it is heat that you need just use a small HPS!(plus you will get extra IR) there is 100w HPS but maybe there is smaller ones! Cobs won't add that much heat unless you use it at full power! Do you have your qb's drivers inside the tent or outside? Did you tried to use pc fans to remove the...

Hi! How much does those COB cost? And why 90 CRI? They are only 129 lm/w @1400mA! I guess cxb3590 3500k CD or even DB now would be much better in efficiency and more effective than those and they cost 30$ each or around! So why did you choose the citizen? It is just a question as I wasn't on RIU...

Hi! 4x4x80...what inches or centimetres??? But 4x4 is 16ft2 so 30w/ft2 I let you do the math! But I guess 4 qb's is what most use for this size! There is a thread on DIY qb's if it is what you want to do! Have a lifted one

Hi! You are right there is not a lot of information about his drying process...i guess it is a fabrication secret!!! I guess it is depend on what do you use...fresh or cured buds and trim or both! If you make live resin you will need to dry and cure the final product but with cured material you...

Hi! People use 3000/3500°k for bloom and some even 4000°k and for pure vegg you can use 4000/5000°k 3500k and 4000k for both! There is 6500°k COB but it is only usefull to keep short and bushy mother plants! Or if you plan on growing a real landrace sativa it help a lot with stretch who can be...

If you have 30w per ft2 it is good imho! You are in the good growers club! 42 x16(for a 4x4)=672g from a 4x4 sounds legit to me! From 480w it is more than honourable! It is what I pull on average and I grow since 1998! I don't say I am a pro but I have experience in commercial grows and there is...

I agree with it! 4 plants in a 4x4 in 10gallon pot! I have 6 in my 4x4 in 8 gallon cause I don't have vegg room atm so I need a fast vegg(just got 1ft2 for seedling) I use to grow 16 in 2 gallon and before that 32 in 1 gallon! Now it is big pots no till and worms! Have a lifted one

Hi! Not at 50w! If you run them at 25w you will go scratch the 2gpw!!! 10 COB per plants wow you must grow monster plants...i get same weight on average on 5/6 (3/4 sat dom and 6/7 indica dom)weeks vegg plants but you can't see the floor and the top is a carpet of buds! Growmau5 almost reach...

Hi! For a 5x8 so 40ft2 you will need 40x30= 1200w! You need this to bloom! I would say 800w to vegg so with 3 hlg-240 you should be fine but 3 inches between diodes and plants looks a bit close unless you dimmed down a the lower intensity! 8 or 10 inches would be better I guess! I have cobs so I...

Hi! 400w HPS over 6ft2 is a bit too much...how many grams did you get on average with HPS???(dry weight) With a more efficient light like COB or qb or strips at low current you should be able to get over 1gpw so 6ft2 x 30w = 180w so you will be able to harvest depend on your skills between 180...

Hi! 100w is not that good..half of it is! You can find better option even on aliexpress! I use my cxb3590 (137w max) at 50w max and I can dim it to 5w mini and I get 1.3/1.4gpw (organic soil no co2 no a/c only an extractor and a fan in 8 gallon pot and in 110days from seeds to harvest) i use to...
