I did a search on bing about coir and magnesium content and found some info
on Wikipedia. seems many fungi growers use coir, probably on a commercial level.
coir is rich in potassium , low in magnesium ( very good for cube production ).
adding some calcium might be helpful, gypsum -calcium sulfate or calcium carbonate
(edit - many have used pickling lime - calcium hydroxide)
probably be best. avoid calcium with 10% or more magnesium.
High mag content interfers with psilocin production.
young coir is cellulose older coconuts husks are turned to lignin later.
I wonder if coir can be enhanced by addin an organic like worm castings?
or if the grain based spawn provides enough nutes to max out each flush?
just some ideas , I am still learning. got a few blocks of coir when my Burma are ready.
very nice thread
