Take a couple of extra cuttings and give it a try on a couple and do what you normally do to the rest of them. See which ones root fastest. I started using a drop per quart of superthrive in the water that I mist the dome with and I swear they root a couple of days faster.
yeah, I've been misting with 1/4 str solution for my last couple of batches. They don't root mch faster that I can tell, but they come out looking great the whole way through, no heavy wilting or yellowing.
