Aaaaaahhhhhhhh.............Take the biggest stemmed ones with least amount of bud on it and clone those........After you harvest leave some bottom branches on it and you'll be able to reveg it..............sometimes a plant loses it's hybrid vigor but some say no...................i've come to the conclusion to take clones before i flower no matter what kinda of strain it is and whether i'm gonna keep it or them...............Ya never know whether it's gonna be a whopper....lol..........If you keep alot of clones you have a better selection of picking the healthiest plants you can...........
