i have had 100% success in the bubble cloners and so has all my peeps i personally know that use them, and when i trans plant into any medium they have all survived. must be my luck or something. i dont even look at them for a 2 week period then i look and there are root systems to the base of the water. my uncle doesnt even light tproof his cloners and they still work. i wonder why people have trouble with them... must be their climate humid or something or probably strain, or maybe method of taking the cut. ? that chem x chunck is gonna be some fire huh. sweet. i didnt notice krome grew her out. i only notice the white and the other white well his are all white by the end hehehe
