Just for giggles I set up a grow space in the basement to see what I could do. In order to assure that I got at least two or three females I planted 10. It's been a month and they are growing at a slow rate but seem healthy. It occurred to me that they are a bit crowded because there are so many of them. My land lady said that I should put them on 12/12 to get them to flower so that I could chuck the boys and focus the light and effort on the females. I switched the light to 12/12 a couple of days ago. My question is, when should I expect to see signs of flowers?
