"Fem seeds are for pussies" says the new TGA shirt. I don't think being feminine is necessarily a bad thing, but I do agree that feminized seeds are less than ideal. Here's why:
1) Feminized seed is produced using hermaphrodite pollen. Hermaphrodites should be avoided as they can herm from stress at any point and turn your sensi crop into a feminized seed F2 crop. I think most are growing sensi for high yielding sticky buds, not seeded calyxs.
2) Males add genetic diversity to a cross. feminized seed is a narrowing of the given gene pool (especially when females are seeded with their own herm pollen)
3) Its a short cut. Most short cuts are due to impatient modern humans and generally detract from quality of the end product, if not downright contaminate it. (ie synth nutes, trimming machines, BHO hash, pesticides, etc)
I could go on and on about why I choose not to use feminized seed. But the main reason I think to stay away is because there are plenty of REAL breeding projects going on all around the world that are using FABULOUS males AND females and actually progressing the game. To me feminized seed is just reshuffling the deck and not really doing breeding at all. I understand that from a home growers standpoint, its nice to not have to cull males. However, if all these HACKS keep polluting the cannabis gene pool with herm feminized pollens, ruderalis, etc. breeders will have to protect their prized males and the value that the males hold may go higher than 'kill em and get em out of the way' status. By the way I mostly grow from clone, but I avoid clones from feminized seed lines whenever possible, except for the original OG, I love her and she came from a feminized seed source in SoCal.
