I was wondering what type of yeilds an average grower would yeild with one of these and a strain like kush.(http://www.pi-rack.nl/pi-rack.htm)
what kind of grow conditions, setup, medium, lights, grow period duration, feeding etc.... the question, as you ask it, is FAR to "general" to accurately get you any awnser. more info and you might get some shots in the dark
4 gallons is hardly nessesary for 12 inches. of plant growth. I had 3 bushy plants about 1.3 feet high at one time. The entire yeild was roughly 5 ounces. Great potency though.
