Just wondering if anyone uses Superthrive and have noticed any differences with using it. This seems to be one of those it either works Excellent or not a bit. If anyone has any personal experiences with noticeable differences I'd love to hear it and how to use it if so.. Mainly wondering b/c I have 2 bottles of it sitting around. Read a long time ago it supposedly would help during replanting of some cactus awhile back. I have no idea if it actually worked or not though.
