For those of you who like using organic material on your orchids, I have found this item and have been using it with very good success. "Essential Plus provides a safe alternative to the use of chemical hormones like IBA and NAA for the propagation of cuttings and production of faster rooting and greater root mass." My phalaenopsis seem to be growing much better roots and some that I thought were on their way out have "perked up". I purchased a case of 12 32 oz. bottles; this is the smallest quantity they would allow me to buy. I have placed on sale, at my cost plus shipping, some of the extra product. I've posted the item in the "Orchids for Sale/Trade" section of the Trading Post.
