if you are looking for a good mother, i would get a standard 10 pack of seeds, grow em out until they show preflowers, keep the best female for the mother and have fun. a mother grown from a standard seed will have a better chance not to hermie from stress than a feminised seed. its really up to you personally though. if you are tight on space and can't grow a large amount of males/females to pick the best mother, fem seeds would rock. i mean grow 4-5 fem plants, keep the best looker for the mom and grow out the other few for the ganja
