Fertilizing in Semi-Hydro Help!

[alexdg]

Hello to all,

I just transfered a couple of my orchids to Semi-Hydro. I was just hoping to get some clarifications how to fertilize this setup. I was previously using an Orchid Fertilizer 25-10-10 by PLANT PROD. Can this be used in Semi Hydro as well?

If not, I was thinking of purchasing Dyna-Gro (5-9-7). But before I do this...do we need to strictly use RO water to distribute this fertilizer or can this be mixed with regular city water?

At what interval should I fertilize? I used to fertilize every 2 weeks with 25-10-10 by PLANT PROD.


Any help and informations is always appreciated.

Thanks all!
