absolutly, ive had good luck wit sunshine mix #4 and promix hp, technically this is still hydroponic, because its not really soil, just peatmoss, perlite and vermiculite, but it looks and feels like soil soo... most call it that. you can mix what ever you want into it, but if using generall hydro, make sure it drains well.( at least as well as when you open the bag, if not better.
p.s. thanx guru
