i was thinking if it's cardboard then why pay $16 for it... surely it could be made here for cheaper, i'll still keep looking though and run some trials. I've looked on google and we dont have poplar here so if I want the steam pasturised poplar i'll only be able to get it from beautiful mushrooms. Are you located far from

Soak some MDF for a few days :P 

Although maybe don't considering it's banned in the US. 

Chip board?  Surely they aren't all bound with a glue. 

I spoke to a visual merchandiser as they were throwing out some birch, but they wanted to sell it to me.  Turns out it was about $20 a log and they were actually putting it in storage to use again.  I know birch isn't poplar.

MDF is no good, found this on wiki

Formaldehyde resins are commonly used to bind MDF together, and testing has consistently revealed that MDF products emit urea-formaldehyde and other volatile organic compounds that pose health risks at sufficient concentrations, for at least several months after manufacture.[4][5][6] Urea-formaldehyde is always being slowly released from the surface of MDF. When painting it is good idea to coat the whole of the product in order to seal in the urea-formaldehyde. Wax and oil finishes may be used as finishes but they are less effective at sealing in the urea-formaldehyde.[2]

here's a good link http://www.timber.net.au/index.php/timber-wood-products-reconstituted-panel.html

Masonite  -

Masonite is formed using the Mason method,[5] in which wood chips are disintegrated by saturating them with 100psi steam, then increasing the steam or air pressure to 400psi and suddenly releasing them through an orfice to atmospheric pressure. Forming the fibers into boards on a screen, the boards are then pressed and heated to form the finished product with a smooth burnished finish. (Later a dry process with two burnished surfaces was also used.) The original lignin in the wood serves to bond the fibers without any added adhesive. The long fibers give Masonite a high bending strength, tensile strength, density and stability. Unlike other composite wood panels, no formaldehyde-based resins are used to bind the fibers in Masonite.

Yeah, or just use saw dust :P

It's going to be cheaper.

Poplar grows everywhere here, it's a weed on the roadsides.

Looks to me like pulverised wood mixed with coir.

I went through the rigamarole of testing out all kinds of woods with exotic spawn when I worked in the USA. Alder=oak=poplar for growing spawn, so far as growth rate was concerned. Oak was a a bit more acidic but not to the point of detriment. We did not grow mushrooms directly from this spawn substrate trial. I do know they went on to grow mushrooms from alder substrates outside of the spawn test. I imagine substitute any of your local usable hardwood and your gonna be fine.

CONTAMINATION

So I got too excited about trying this product and I forgot to bleach the bath tub :(

However this did show me there is a small error in the instructions on the pack. It only says soak in a clean sink and the average joe would wipe out their sink with a cloth and the sink would be full of contams. This sort of kit should be done in a storage tub that's been wiped out with a 10% bleach solution.

Green mould to the thousands LOL probably should have posted a pic but just imagine some green cardboard.

will try again soon.
I also have some sterile grain waiting to be knocked up so i'll through some dried spawn in and see what happens.

Any sign of dried spawn sprouting some mycelium?

1.  Did it say to soak in hot water, like a bit of a pasteurisation?
2.  Don't chuck out the contammed lot, see what comes of it outside.

1. No the thick sheets of pulverised poplar had already been steam sterilised before packaging apparently.

2. yeah i'd agree with you on putting it outside, however it's like 10% humidity here at the moment and 31C it'll die, plus I already chucked it. No biggie I can buy another packet if I want. I still have 4 others that i'll be more careful with.
