So I’m going to switch from pure liquid hydro to Promix, my question is, which Promix is preferable?
Promix HP or BX are good choices. I would stay away from any that have time release fertilizer added
I use the BX. They are about the same
I love the pro mix vegetable and herb mix I’ve used it on all my grows and get great results with it. It’s cheap and i add a couple things to it like manure and some trace minerals it 14.95 for 2cubic yards here
