Op gets absolutely scammed when buying Marijuana seeds (125$ for 3 seeds). Cope, seethe, and mald in the 200+ comments when people point out he overpaid for trash genetics AND he couldn't even finish a soil grow.

the real dwc advice

good for 4-8 lights.

you need a water chiller

doesnt scale well over eight lights, and the extra equipment isnt worth the money under four lights. the yield and growth rate are bar none, but if your relative humidity drop under 55 (esp under 45) you will see leaf drooping because vpd issues are exaggerated under dwc

if you run a sealed room you are gonna need a swamp cooler in veg-early flower or a badass ultrasonic fogger to keep RH levels high. i used a fogger, but get used to wiping crust off everything in the room, even if you feed RO water to your fogger.
