I plan on growing a couple plants 24" high then flowering them. Whould 4L be alright if I flower at 24". how about 36"?
Hell, I wish I'd used 5 gallon pails instead of the 3 gallon pails I'm using, I started flowering around your height and I have to water every third day. It's a pain in the ass. I will be using 5 gallon pails next time around.
