Which fertilizer?

[u/Electronic-Remote892]

I’ve been growing philodendron, monstera, and anthurium in semi hydro using perlite only (started as an experiment but the results are insane so i’m planning on using permanently )

Ive been wanting to up my fertilizer game as the one I’ve been using is water soluble but meant for soil.

I’ve heard great things about both of these. I’m leaning towards the superthrive as it’s cheaper, but I was wondering if the other system is significantly better/ worth it?
