I just transplanted 12 clones from cups to 4g pots. Should I water them now to get some moisture in the new soil?
I think you're supposed to water them a lot. I've heard it's impossible to overwater transplants. But don't take my word for it as I'm not positive...
You shouldn't let the soil dry. Did you water the soil before transplanting? Or did you just put them into dry soil? Pre-watered soil with humidity dome is a good idea.
