This year for the first time I have been using Superthrive, Nitrozyme &
O.G.P. on my orchids, I would like to think my plants look healthier & I
have certainly noticed increased flower numbers on my Phals. as well as
previously non flowering Phals producing blooms.

Has anyone else used hydroponic additives on their orchids & which ones do
you use/recommend?

( I am not growing my orchids hydroponically, I use bark chippings.)
