Re: DIY Biochar
Lump charcoal refined(broken up to smaller pieces) to biochar size can hold a fair amount moisture.
Biochar is lump charcoal crushed and repurposed for growing plants.
The smaller the charcoal particle size the more moisture it will hold.
The larger size of the charcoal the the less moisture it will hold.
Same with perlite.
The smaller the particle size the more moisture it will hold.
And the larger particle size the less moisture it will hold.
Perlite is a fantastic medium for hydroponics .
Both materials mentioned above will hold up to 40% +moisture and nutrients for your plants.
The op in the first post is spot on ...how to make lump/biochar.
