What your going to want to do is to get your mother plants growing if you dont have them already. while you are growing your mother plants you will want to apply some LST (low stress training) by tying down the branches or the main stalk to get more tops. there is pleanty of info. on this site about it. lets say 5 of those 10 seed are female, out of those five mothers you will be cloning, all at the same time. once your mothers have the amount of tops you want (i.e. 10 tops off of 4 plants will give you 40 clones), you will want to take all the cutting of off ALL BUT ONE mother plant. the reason for saving this other is so you can produce more clones in the future and keep the strain.
once you have cut all your clones, let them root (its a good idea to always over estimate your amount of clones due to the fact some clones wont root). the reason to take all the clones at the same time is that they will all have the same life cycle, which will result in a nice, even canopy through their grow and all your plants will yield at the same time. hope this helps. good luck.
