Pro-mix / Bulk garden soil / Bagged potting Soil... Help!

Here the deal, 6 month per year i live on a frozen land and all the nursery store are closed. So i have to squirrel all my gear/nute and of course, medium.

I would like to be able to mix my medium in the summer time, and store it in my outdoor shed (non heated) in 5gallon container and use them to grow indoor in the winter season...

Option 1: My first idea was to hook up my trailer and buy a ''tractor bucket'' of garden soil... it go for about 30$. Then mix it up perlite/bone powder/casting, store the mix in 5gallon container and they will be ready for winter..


Option 2:
Buy Bagged potting soil (Myke (mycorrhizae) or wtv), add some perlite, store in container.


Option 3:
Never used Pro-Mix, heard this is a soil less medium? Maybe less trouble to store but still have to add casting/bone meal...



The thing is, i would like to ''dispose'' of my medium in my outdoor vegetable garden, its a ''in ground'' garden, not potted or anything. Do pro-mix is usable in garden?

Promix is referred to as a soil-less medium because it doesn't actually contain soil but sphagnum peat moss as well as perlite and vermiculite. When you open the bag though, it looks just like soil. So it's not going to be any easier or any more difficult to store than soil. I get the Promix HP (high porosity), but for every two parts of Promix I add one part perlite so it breathes even better. I have a new plastic garbage pail and I mix the combination in the fall for the winter. Although others might frown on this, I re-use the Promix (after flushing it well) because I don't want to be outside freezing my ass off in the winter mixing more of it. (I use it twice). I'm guessing your vegetable garden would welcome it, as long as you can explain the white perlite pebbles to nosy visitors to your garden.
