This is my second grow but first in a proper medium. I wasnt planning on reusing the pro mix.
At the time I didn't know that pro mix hp, ewc etc were available in small bags but I found a place that carries them. In the meantime I have 3.8 cuft to use up first.
My hydro guy uses a simple mix for his soil.
Pro mix, ewc, and Gaia green sand. Cooks it when he remembers but he says it kicks ass.
Next time around.
