I have a Rex begonia (Super Curl) that I took some leaf cuttings from for the first time (thanks to the great instructions from this forum). The little plants are finally visible, but I'm wondering whether I should keep them under plastic for awhile until they are larger or remove the plastic. I know these guys don't like to get too wet, but like humidity so....not sure what's best. They are under fluorescent lights in the basement at the moment with my other baby plants.
