has anyone ever used pro mix organic? If so is it any good?
I've been using the promix herb & vegetable mix for years. I usually get a month to 6 weeks before I have to feed. And usually by then it's time to pot up. It can be a little hot for sativa dominant plants, you'll get a bit of nitrogen excess, but mine grew through it, just had dark green leaves. You'll want to stay away from the flowering plant blend, it is
waaaay high in nitrogen.
I would add more perlite if it's staying too wet for you, but I've never had a problem. I water by the weight method.
I use it, and unless someone shows me something better for a comparable price I'm going to keep using it.
