Sup Bowser,
Actually, no need to clone in the dark. I have found that cloning under a humidity dome and a cheap floro works just fine. The important part is too keep the humidity up high and the overall temps above 80F if possible. I clone using cheap Jiffy pellets and I usually see roots in about 7-10 days. I actually tried leaving the clones under bright lights and found that they wilted my plants almost immediately. Low light and high humidity works every time for me. Hope this helps.
