In all my readings here it seems that a high percentage of folks like using coir for substrate and casings. While there is a few "grow stores" in town that probaly carry it, I was just wondering if there was an equally good north american product that compares.

any help appreciated

for use a substrate proly only worm castings would be on par with coir,
peat ain't gonna cut it.
peat's ok though as a casing,
just understand that nothing is quite the same,
not exactly interchangeable in every regard.

Only for the substrate and only if you weren't already planning on using straw or poo or a mix thereof, people have posted good results using critter country. Its a straw based kitty litter. I point this out cause it seems to be pretty easy for most people to get at pet stores. Other similar brands too. You can get coir at pet stores too, but its more $$$ there. Also on eBay.

Yup ,shredded,,,It has lots of fine fibres which mycelium love ...A 3 dollar bag goes a long way ..Just remove the larger chunks ..The nutritional value is similar to coir..
As a substrate with verm and poo - it's excellent, or just spawned heavily by itself ..
I'm using some now with a couple o grows and maybe a hundred times so far....
i think it's actually superior to coir ,except for having to sift out the chunkie chunks...

What kind of mulch do you use? Any brand name that you can pass on that I can look up?

Thanks

P.S: I'm also curious (but dont want to make a whole other thread) can long grass like quack grass ,which grows 3 feet high and has invaded my garden be cut, dried, and treated like wheat straw? I removed PILES of this sneaky grass last spring and just composted it. Has anyone had success using mature grass stalks (not lawn clippings) as a straw substitute?

This also brings up the thought, what about using canary reed grass (grows locally) also known as the DMT bearing Phylaris grass as a wheat straw substitute? Can the alkaloids in the grass be assimilated by the mushroom mycelium?

more random thoughts

I was meaning using the dried, chopped, pasteurized grass AS an alternative additive to a bulk substrate mix. I'm trying to tink of local materials that might work.

Some very cool readings about grass in Space Cowboys posting:

http://mycotopia.net...read.php?t=6556 chapter 4

actual pdf file is: http://mycotopia.net...39&d=1135019290

The whole chapter describes alternative substrates for mushroom cultivation.

Those grass materials will work great.

I'd really like to explore what locally generated fibers can have good results. Every area has their special ones that work best.

Here's a current example of how well mycelium takes to shredded mulch.

BRF cake,crumbled and mixed with the Mulch in a gallon ziplock, then cased with
more mulch ...Spitting out some chunky boomers...

mulch can be a LOT of different materials, from leaves to grass to bark.

Well specifically Hardwood Mulch is pretty uniform ,in that it's primarily sapwood thats shredded from sawmills ,,I have not seen much bark in the mix...From the many different places i have purchased , it all seems very similar but the tree type proly quite variable...

I am having some incredible luck with shredded cardboard pasteurized with worm castings. I just take the big cardboard jiffy pots, used for plants, tear them up in little pieces and mix castings in with them. Then dump boiling water in, let it soak overnight, drain and let it dry for a day in the sun. It seems to soak up the water soluble nutes in the castings. I put a little straw on the bottom, then my mycellium, then a layer of cardboard, another light layer of straw with some more castings, more myc, then the last layer of cardboard. The myc is tearing it up! I am going to try mixing in some shredded hardwood mulch on my next bulk though, I am having horrible luck with coir. I got this brand called Big Daddy from the hydro store and it doesn't seem to be doing me any good. Any body else have any experience with this brand?
