If you get non-feminized, grow them until you can get a few good cuttings off each plant, root the cuttings, as soon as they root, put them in a different area with 12 on / 12 off lighting. Make sure the dark period is really dark.

They'll show their gender and die, but if you labeled which plant each cutting came from, you can cull males before they get a chance to release massive amounts of pollen.
Mustelid Reviewed by Mustelid on . 2 very simple questions Noob to the site, done my research, but can't seem to find answers to these specific questions. 1. Non-feminized white widow seeds are way cheaper. Wouldn't it be cost effective to just buy ten non-feminized seeds, then wait two or three weeks to see which ones are female? 2. I plan on using Fox Farms Ocean Forest mixed with Miracle-gro brand Perlite. What is the ideal ratio? Rating: 5
