I plead the 5th amendment I will not answer but you probably can add biochar, perlite, azomite, rice husks, crushed oyster shells and bat/rat/chicken you know....I wish someone strong would come help me turn my compost pile....he said feebly.
We have free compost where I live, too. I have thought about using it for cannabis, but decided against it. My thinking is that we don't know what's in it. It's usually made from plant matter that's collected from the community. It probably shouldn't be used for anything that's ingested. I think it's best used for landscaping.
Plants grow well in compost. It's essential in nature. I make compost for my flower garden. It looks and feels like dark, rich soil. I doubt it has all the nutrients cannabis needs. So, even though I have some that I made myself, I use Fox Farm soil with amendments.
At a very cool garden in pyin oo lywin myanmar they burned compost before using it on their plants and orchids. British occupying soldiers built this replica of Kew Gardens and a local took over when they left. Gorgeous orchids, lots of separation so people weren't crowded together.
Good compost is rotted vegetable matter. Note the use of the past tense.
That does sound very cool. I have never even thought of burning compost, so I'll do some research about it.
There's a lot more to compost than water and carbon dioxide.
