before you take any clippings, make sure you have your clone medium ready either rockwool, or peat pellets, and also your choice of root hormone. There are several threads here about what to use and what luck others have had. So depending on if your going hydro you will want rockwool, if your in soil then peat, others have just put the clippings with root hormone directly in the the medium they use (when using soil). I wouldnt take any clippings unless your mother plant is about 6 weeks into veg, i'm sure people have taken them earlier but its mostly a personal choice.
