Please do not trim. Leaving them out of a good system is not good either. Been there done that. Have extra's now that i was trying to save for the next round but I don't think they will make it.
Once those roots start to come out they must be dealt with soon. If they start to dry and they will, the clones are stunted and take a long time to recover if at all.

Oh good idea. I am going to get mine in a bubble cloner I have with just neoprene collars so they can grow and still be good to go into netpots when needed. This will save me so much time.

Thanks you for making me think about this problem. Got to go now.
