Ok sorry to keep bugging people about this but the leaf cuttings that I took about 2 weeks ago have pretty much all turned black. the base of the leaf is still white but the part that used to be green is now black. I have it in a rasberry container sitting in a tray of water. they are sitting under a 42W compact flourescent bulb for 19 hrs/day. The soil mix is 50/50 milled sphagnum moss and perlite and is wet enough that if you picked some up water would drip out of it. The bases of the leaves is about 1/6-1/8 inch below the surface. Is the blackness normal or am i doing something wrong? and if i am can i do anything to save them thanks in advance
