hey there caligirl- some strains are harder to clone than others, but i've never had or heard of anyone else having any specific problem cloning plants grown from feminized seed.
U can pretty much clone anything U like to, as long as U know how. It take a bit of practice but cloning in general it's easy. Just a very few strain will give hard time.
i'm just about ready to try some jacki white clones, i know one is rooted in the most kindest way lol, and checking yesterday looked quite smug and leafy with herself, was in small pot of dirt. i remember years ago i tried about 7 fem clones of ? grew tp about 16 inches then hermied. ps these are fems. jacky white is a top shed outdoor producer.
