Ok i got a 10x20 shed growing weed in it heres my illustration you think having bout 20 dual 4ft flourescents will be good enough for lets say 300-500 plants(keep in mind there are 2 levels of growing, and only growing them for 2-3 months then me and 2 friends are splitting them up and growing them outdoors). Any help is much appreciated going to be on here alot the shed comes soon.
I am thinking no. Intially it might work but as soon as they start growing, it wont be enough light. 300-500 healthy plants is alot to ask of shop lights that at most (if u buy 40watt bulbs) put out 80watts a piece 80x20=1600watts. 1600watts =114000lumens. Which sounds like alot. BUT when youre spreading that out over 300+ plants.. It wont work. You need more light.
ok so last night we decided we are only going with 1 layer of plants, for extra light we going to put some cfl's in the middle facing out towards them(rotating plants periodically) still not enough light??? who knows
More CFL's then i assume, dont want to buy some fancy lights when we are only growing them for a short period of time till there about 2-3 feet then taking them outside know what im sayiing but thanks though +rep
ok so with one layer how many plants is it? and im not saying to spend more on fancy lighting. but you need enough for them to survive. how many plants are you going to have and how big they will be and ill tell you how much light you need.
300 plants 3 foot tall....going to my friends to figure out all what we are using and ill post in about half an hour thanks for taking the time to post
ok so 300 plants 3ft tall. you're going to need alot of shop lights. it might be cheaper to go HID(MetalHalide). Ill tell you why. with a 4ft tube floro unless you special order t12 grow tubes. 40 watts and 2000 lumens is the most ull get from it. and considering you need 3000 lumens per plant at 3ft, that would mean you would need 2 fixtures for ever 3 plants. Idk bro.. you might be biting off more than you can chew. 300 plants is also alot for your space. IF your set on doing it then you probably should get like 3-4 100watt or bigger Metal halides. thatll be the best way to go. actually ( i edited this) I just went on the web and looked at specs for a 100 watt MH and you only get 9000 lumen and you would need 100 of those to produce proper lighting for 300 plants 3ft tall. I think at the begining you wont need a bunch of light cause theyre sprouts but once they get full size.. youll need every bit of it. getting 9 1000watt MH fixtures will be optimimal for you cause of your space and you have to think about heat/venting/electric bill/etc. you have alot of work to do haha
Have you ever grown before? 300 plants is way too many to manage, let alone the Jail time if you get caught with that many.
This will be my 4th year, I've spent plenty of time on know how to grow it except for thiss many and trying to figure out how much light i need....i grow in a country where its legal. I have my MJ license.
they r fucking gay i grow 600+ i use a 10-22 you should be all right i use 15 shop lighting so you r ok just go for it.
