Superthrive is a mystery! It's a vitamin packed solution that only takes a drop or two per gallon to make a difference in your orchids! People swear by it! I use it when I transplant orchids, or when I have an orchid that's not doing so well.. they get a bath of SuperThrive and Physan solution to perk them up and make them healthy again! Most people use it by the drop in their fertilizer solution.. the best Cattleya grower I know uses this product, and his stuff is OUTSTANDING! Try it.. you'll like it, and a little goes a long way!
