Before I had a real garden and used the plastic grow bags or other containers I just used ProMix or other mix straight. But I am wondering if the additional aeration from the porous pouch do I need to "heavy" up the mix a bit to hold more water?

I would also like to extend the mix some if possible? If I had compost leftover I would throw that in but used what I had available in the garden.

I was thinking of using 2/3-3/4 Promix and the rest of something else if I could find a cheap alternative?

Any ideas? And thanks!

You are on the right track, Promix would be too light by itself and dry out incredibly fast in Root pouches. Experienced this myself year before last. Some high quality compost would be a good additive imo. Also mulch is a necessity where im at in CA.
