Hey greenearth, figured id put my two cents in. As far as naturally feminizing your seeds ive heard of hormone solutions you can use to soak the seed in but the cheapest and most effective way ive come across is the banana peel method. You take a banana, peel it, wrap the peels in paper towels, and place them in a bag with the seeds you wish to feminize. Open the bag every 2-3 days to allow new air in, change the banana peels every 4 days, and do this for about 8-12 days straight. The longer you do this the higher chances for females. Id wrap the seeds as well, you dont want to start germinating by accident or before the process is complete. The process takes place as the banana peels rot, producing a hormone known as ethylene. This hormone is what feminizes the seeds and is also found in the liquid solutions i talked about earlier. I proved this to myself on my last grow; 4 white widow seeds and 4 bagseed put in for 9 days and 6 came up female. Would have left them in for longer if it werent for time constraints. Hope this helps...
