xcrispi Reviewed by xcrispi on . Can I grow White Widow in a 3' space? I have 5 feet of space. I planed a SOG grow, with the DWC tubs and 1000w HPS light in a cool tube, I am left with only 3 feet. Is it possible? I can shorten the tubs but at the most I would only get another 6". what do you think? Rating: 5
