Topping / fimming Parsley

I was given a few Parsley cuttings from a local greenhouse, I have them rooting in my aerocloner and they are already showing roots after just 48 hours (why cant MJ be that easy?) They are just tiny cuttings with only 3 leaves each, 2 off the nodes and 1 in the center from the stalk. There so small cause they were actually selling them as food but gave me some when I said I wanted to try to root and grow them.
My question is can I use a HST technique such as topping or fimming to encourage branching?

well if parsley floats your boat!!! seriously though, i think most plants will improve from some of the same techniques that are applied to our lovely lady MJ! parsley is the same basic structure right, stems which grow nodes and leafy? this is strictly my opinion, but I dont think it will hurt. besides, if they show roots that fast after cloning, just clone some more and do some tests. should be fun, and legal, so you can grow a bunch!

Hit it with a week whacker that will speed up the braching... we can call it the fiwwi method (fuck i weed whacked it) JK
