how do you clone with the bubbler set up and what are your success rates? i'm currently doing this and still havn't gotten a goo success rate yet. i use a shoe box size plastic tupperware spray painted black on the outside, a small heating pad underneath on low to keep temps btwn 75-85, and a 5 inch airstone. there are six plants at all time in there. out of the last batch 4 of them rotted after 7 days and the other two are still in there w no roots?!?!?
