yeah, I've been using Super Thrive for the last two years. (well, schick, one bottle of this stuff should last a decade) and it SEEMS to help. I only bought it and started using it cuz others , on many web sites, had reccommended it Can't hurt right? (too much)
what really annoys me is the package and the promises it makes, its total Bull Caca and with all the talk of guarantees on the package, there actually isn't one.
if you read it all closely if you want to take them up on their " guarantee", you have to write them and tell them how you were growing things. I guess then they'll decide if you deserve your five bucks back if your a good enough gardener.
I think you might be better off saving eggshells to make some homemade Calcium phosphte.
or starting a compost pile.
Happy Gardening, you hot heads.
