I have used Superthrive for several years
on orchids and found it very good.
So far I do not believe that Powerthrive is
available in the States. Is it made by the
same company?

Powerthrive is a growth and bloom
enhancer that contains vitamin B1 . It is
made by Garden Friendly Products of
Vancouver, British Columbia. I don't believe
it is available in the U.S.A.
Cheers,
