not ever heard of radiation to feminise seeds - the most common methods are to stress the plant - this can as im sure you are aware be done by inducing
Light stress
Heat stress
Cold stress
Fertiliser stress
GorillaSeedBank Reviewed by GorillaSeedBank on . Wierd seeds this year? Don't know about the rest of you, but I like to use fem seeds for the new strains I want to try. Last years seeds were great, 100% germination, strong growth, great form. This year.......... When I was in school I did experiments with radiation and germinatiion, this years seeds came out exactly like the very high radiation dose group of seeds I had seen years ago. Anybody else see a group of bad seeds? Rating: 5
