I have never heard of lighting having to do anything with the sexes of your plants. ...

Whether your plants are male or female has to do with genetics, much like humans. In fact you can even buy seeds guaranteed to be 100% female plants. They can gaurantee this because the plant those seeds came from has a genetic code which only allows it to produce female seeds.

So, whatever percentage of your plants are male/female has been predetermined by the genetic code their mother passed on to them.
seriousgrower Reviewed by seriousgrower on . Few Questions i started my seeds under 24h/light, now for about 5 days it's been under 24 hours light, in doing my research i should have put them under 12 hours to make females. Am i doomed to have a crop of males? or if i change the light regiment to 12 now am i still safe? ALSO, what are the chanses of haveing a decent strain if the seeds are from dimes ive purchased and taken them out??? :confused: and is there a way of finding the strain without having to find a professional???
