Powder against gel

This is a rooting powder, and in use that is a different thing from a rooting gel: you dip the cut into the powder rather than applying gel to it. Both are in this category, and it is not a question of which is better but of how you work and how many cuttings you take at once. Read the directions on the product page, because a powder is dosed differently from the liquid you may be used to.
