I've grew fem seeds since they were first available. It's saved me a bunch of money because I don't have to transplant males into a expensive soil mix....also space for indoors. Mainly people like regular seeds to use to chuck pollen or breeders use. They've a lil cheaper and would be ok outdoors if you wasn't planting in container or beds....good guerilla growing with regular seeds. Unless I'm chucking pollen I don't need males myself. Most fem seeds have a lil trouble when they pop sometimes the seed hull will stick on the seedling. I use tweezers and very carefully slide the hull off when needed. After you get them growing it's on....females is what I like!!!!!!
