Hellou , I need your opinion , how many autoflower plants can I put in a 240x120 tent with 2x hps 600w lights? how many liters should the pot be? and how much the yield can be?
Best thing you can do is look at diaries in 8x4 tents and gauge what looks good and what worked from these guys. If yields your concern - I’d go photoperiods. Autos are just inconsistent.. and less yield.. you’ll have some you chop at day 70 and some will go to day 110.
Go photoperiod - go 5 weeks in Veg. Then flip. Most will be done in 8-9 weeks after flip. That’s 100 days for better bud and more of it.
I’d put my yield at 4 pounds easily from an 8x4 with photoperiods. Autos.. won’t even try to guess
