I have looked for related topics online and I can't seem to find much.

Which is recommended? Which do you personally use?
This will be used outdoors. I'm new too this, so any help would be appreciated.

don't buy it...make it! :black dirt, fireplace ash & charcoal, manure(preferably cow), straw or forest litter, grass clippings, kitchen scraps, fish bone meal, bat guano, azomite, ground oyster shells, etc. ...to really get it going, get some biodynamic compost starter from josephine porter institute for applied biodynamics- it's cheap, yet worth more than gold! just get it and apply to the pile...it'll take a few months to get the finished product, but you'll have the best soil in the county for sure...it comes out in the overwhelming gushy smells, and the best possible taste!

I will avoid the compost which is labeled Peat Free with all the extra items then.
I have never heard about 'Biodynamic Compost' before.

Does anyone else have opinions on these compost types?
Is there a certain type of compost I should buy, I will be avoiding Miracle-Gro.
