yes.. 3 gallons is fine.. BUT if you are growing outside.. I would use nothing less than 5 gallons.... (although you can use 1 gallon or smaller if that is WHAT YOU MUST DO... but its lame) LOL

Garden Knowm Reviewed by Garden Knowm on . cola question I was wondering if anybody could go into detail as how to get clones with only one big cola and not a bunch of little buds. I dont really have a lot of space and seems like the best way to go but I was wondering if it would be worth it since I only have a 100 watt hps. Its in a cool tube though that is warm to the touch so i think i could get it within a couple inches of them. Rating: 5
