Hi Anthony,
i'm guessing you've got them in wet kitchen paper at the minute?, i'd be a bit worried about using dirt from the garden, i remember trying this the very first time i found a seed in some bud, the amount of insects n bugs that was in that little container was unreal, if possible i'd try and get down to the Garden centre as soon as possible, just get some cheap compost from there, or do you have either root riot cubes or perlite laying about the house?
Peace
