I did the moist paper towel method and banged them between two plates, stuck them in my airing cupboard for 2 days and kept them moist and hey presto, done! they want no light until their leaves come through, just warmth, but as seeds they need to be in DARK! as long as they are spaced apart so their roots don't tangle, 3 in a bag is fine. remember to be incredible gentle when handling them too as they are extremely delicate as seeds
good luck! you're not that far behind me (my girls have just started showing their first propper leaves) and I'm on my first grow too
