Hope your running co2 in that sealed up room..

Sorry to change the subject, but dang 36 per light, You should be able to cut that down to 16 or even 9 and get the same yeild.

Word purpberry

it works for me my friend. about a pound a half per light. and im never running the same strain. and yes, we are running co2, just added it, hence the sealing of the room and running into humidity problems

and as far as yeilding as much with less plants, yeah it can be done, but with longer veg time.

i know your not gonna argue against SOG being the best commercial way to grow. my club has 1000+ members, not really close to our plant count. so thats not a concern...

i was thinking about switching to 50+ plants per light... ive got 910 grams off of on tray, id be hard pressed to do get close to that with a lesser plant count.

here a couple cell pics so yall know im not bullshitting you.

(keep note i didnt set these rooms up. ive recently came into this mess. lol making LOTS of changes)
