True,,,,but it is possible to get over 2lbs a plant, indoors, under 1k MH/HPS lamps in a 10'x5'x5' area - Time is factor here as they would be a pure sativa, like maybe Aryjan's ultra haze #1 (we've done it).LOL YEA MAN.. aha thats if u had all the space in the world to grow and all that shit.. Preferably outdoors. IMO
