I'm glad to finally see some technical criticism of Superthrive :thumbsup: ... I've ridiculed the stuff for years, but not being a botanist, etc., I couldn't legitimately say 'why' it's no good, only that I don't like it ... I was surprised to see it doesn't even help rooting, I did mistakenly give it credit for that ... it's hard to look at a Superthrive label, and not recollect old-time medicine shows ... wonder how it works for baldness and impotence ?
