I have started 10 different varieties of leaves about 2 wks. ago. I put the little plastic cups in ziplock baggies under fluorescent lights. I open the baggies every day or two to let in fresh air. I noticed the medium is pretty dry to the touch, but there is alot of condensation in the plastic. Should I leave it alone or spritz with water? I also noticed some of the leaf pieces are wilting. What should I do for them? Thank you for your help.
