With what he said, do you disagree?  |
Sure we can chat...
I use all three materials that you mentioned.
I make my own biochar like you by soaking(charging) the broken up store bought lump charcoal pieces in a slurry of organic ferts.
Same charging process with the medium perlite I use.
I choose lump because it is already made and in a bag.
I could choose to do a burn pit and make my own ....So what is the difference between what is in the bag and what is left in the pit?
Something more controlled and scientific a better product?
The end result is whatever you want to call it.
A quick internet read keywords/"water retention of perlite/crushed charcoal/lump charcoal will give a better understanding of just how much moisture these substances are able to absorb and release.
Another Youtube search "how to make biochar/charcoal " will further help forum members understand the process.
