I get 100% females from un-feminized seeds all the time, environment is much more important than genetics for controlling male/female.
Really? How...
the fan will help alot in building strong stem structure on the plants i use a small 3inch fan that blows underside of lights but also hit seedlings tops. i have no problems with extra males in the garden because of my praticesThe fan will help with stem strength a tiny bit. The male-stress it induces is far from worth it. Supercrop instead. The plants will stay shorter, be more vigorous and have vastly improved nutrient uptake abilities. Wind-whipped plants will still be tall and scrawny with poor nute delivery, they just resist tipping over a bit better. Supercropping FTW
It doesn't matter that your seeds are fem. Femenized seeds are just inbred forced-hermie females, there's no magic going on with them. Despite the name a fem seed can produce either a female, hermie or male! Fem seeds just slant the odds in favor of getting females, doesn't mean you will get them automatically.
