I've been thinking about some people saying the cuttings die after they cup them. Some of mine have been in cups for about a week and they are thriving - no gnats either!! I haven't watered them since, but I did use tepid water instead of cold from the faucet. I'm thinking that may have something to do with it - pouring water that is 15-20 colder then room temp would shock me!! What about the little roots?
That's what I've been doing.
