The h2o2 can inhibit root growth on clones, not sure about using the roottech gel but unless someone says something else I wouldn't do it. But if you do end up throwing the gel in only use 1ml per gal as it is super concentrated. Now on the other hand I know people that just take clones and dip them in rooting solution then throw them in the cloner with just ph correct water. Just remember root rot is usually caused by high res temps
