If we are talking about the 5 gallon buckets . The ones you can add on to the system, then yes it is possible. Oh yea and a big light. 1000 HPS hortilux eye. I have 6 plants in about 7 gallons and got 8 oz's off one plant. When they are tight one or two will be dominant. You can build that system for a lot less. The better hortilux is going to double my yeild. I think I'm looking at a little over a pound this time. The trichomes are coming and the buds are getting fat at 6 weeks.
