if you are using feminized seeds and there not "popping" up, it is something that you are doing wrong, out of 10 feaminized seeds you should get a minimum of 9 but generally 10 outa 10, unless you bought off some crap website or unreliable store/person
All i do is get a cup with some soil in it, take a pencil and push it into the soil about 1/2" -1" and then drop the seed in the hole cover it up pack it lightly and water it but not too much then within 1-12 days you should see them sprouting. Make sure you have a good temp, keep above 70F i'd say 73-74
