What about AirTerra? They told me it’s granulated 1-5mm size. Is that good?If it's small enough, I don't see why not. Black Owl biochar is a good brand.
I was using fire place ashes and screening the char from ash. Then, put it in a pillow case and smash them with a rock and hammer. You don't want to bust up your side-walk doing this! Then, you can charge it and add it to your compost. I think that char is more important when you have low organic matter, like ground soil. Also, you should ask @DonBrennon about using too much char. I think that he is still around?Ok, so small is better? Do you know where I can get black owl biochar in Canada? Ontario, specifically. Thanks
yeah, I'm going to stick to just under 5% biochar, seems like the magic number. Thanks!I was using fire place ashes and screening the char from ash.
