fox farm: solubles: can I use them standalone, no liquids?

[wannagrowthebest]

if not, why not?

I wanna get away from buying water, lugging water around, and piling up so much plastic--wanna go all powdered.

note, GH has their powdered formulas, anybody using just those?

It says you can use the solubles as stand alone but the NPK values are shitty for a stand alone fert if you ask me. I've not tried it but give it a go and see what happens. Report back if you can.
