Hmmm... i have also been thinking about that and iv found that lots of people are looking into the effect of cfl lights its been said that cfl lights force the plants to pick a gender when it starts to flower and its said that it increases the chance of the plants being females by 80% i will have to do some more reading but with that and picking out the males at the right time and good care I'm sure its quite possible to make sure all the plants are females before they get to the stage where there stems are starting to get compact and start Turing into one mass plant i would love to see other peoples advise on this and ideas or info please and thank you


And as you can tell in the first picture you can see the background is of the same area as the last picture and you can tell the 2nd one is a marijuana plant i can find more pictures of this
