yo i made like 3 bubble cloners for under 50 bucks from walmart a few months back and its been the best method of cloning i've seen yet. my clones root in 6 to ten days then its off to the coco. i use hygrozyme in me ro water and it seemed to knock a couple of days of my root time and it keeps the slime down too. definetly go with the heater i use a grow pad from the hydro store. peace
