Yeah, that's what I'm saying, coir and wood pellets can simply be hydrated and then used because the processes that make them in the factory result in a sterilized, cooked product.  Doing your own pasteurization gives you piece of mind and can get rid of contams that may happen when you're mixing in gypsum or hydrating it. 



What part of the process cooks coir?

For the OP:

Research is great and all, but 10 tubs?  Seriously?

I did this research on a much smaller scale, using a couple jars of spawn I didn't really have much use for.  What happened was my unpasteurized coir substrates colonized very rapidly, and then...didn't fruit.  At all.  Ever.

Good luck with those 10 tubs.

I've just been reading through some sites on how they process coir. I don't believe there's any kind of heat treatment. I doubt contamination would be an issue even with unpasteurized coir. I'd be more concerned with yield.

Yeah my mistake, it's the wood pellets that are heat treated.  In any case, the bucket tek doesn't do much against contams if you try it with dirty substrates, coir is simply naturally contaminate resistant.  That's interesting that cooking it increased yields, I've never tried doing it without proper pasteurization so I wouldn't know the difference.

Yeah the heat treatment is supposed to increase yield by breaking down the substrate some, particularly with uncomposted substrates. I wouldn't be surprised if they colonized a little faster for the same reason. It's kind of counterintuitive at first but the more nutritious a substrate is to the mycelium the more slowly and thoroughly it colonizes it.

It makes sense given the fact that cubensis prefers to grow off fermented grass that has shot through the gut of a cow rather than having evolved specifically for breaking down coconut husks.  I used to have unlimited free HPOO and that stuff had amazing yields on all sorts of species, I definitely am bummed that that connection dried up.  :lol:

I gotta say I'm very surprised at the yields coir gives, especially considering it's low biodegradability. In nature it supposedly takes 20 years to break down. I suspect the pasteurization is an important part of that.
