No,the way Ive always grown is in 3 gal buckets,I give them 2 liters of feed every 3/4/5 days.I know its not the done thing but it works for me-until now of course,Ive obviously watered them drunk then watered them again next day without checking first.Doh!Wont do that again though,the 2 plants are a fecking mess! ;-(
