If you want to root your keikis quickly, you can use another product the same company sells for rooting the keikis. I never used either of them, but if one works so well, the other is bound too. The option is to spray your plant with 100 ppm IAA or NAA, both are auxins that will promote root development. Also consider 100 ppm Vitamin B complex (Vit B1 promotes root growth).
