Nice write ups Fabio. I like the linked one here
http://www.freesporeprints.org/smf/index.php?topic=48.0

So you pasteurize the sawdust/chips in boiling water for ten minutes? then add the water and substrate into the rubbermaid bin to sit and cool. Shaking helps evenly distribute the water onto the substrate?

Then you do the inoculation by pouring out your grain spawn onto the substrate and then bagging it?

What is your spawn ratio?

Also I know it's a lot of questions, but what do you think of those bags? They look like the SacO2 bags from Europe. I heard they're one of the best in the industry.

Hello Jeremy, hi all :smile:

The term i prefer to use is boil :smile:

i boil them 10 minutes to rehydrate better, then i pour the hot (dark brown) water with the woodchips into the bin with chopped "tronchetti"(=the ultra pressed sawdust used for wood burning ovens or fireplaces). Mix and let cool. Is important you shake hardly a minute or two. The water in something like 20 seconds will be totally absorbed by the pressed dried tronchetti.

Then i inocule when cool, mixing the grain spawn with the pasteurized substrate. I mix it shaking the box with the closed lid.

I suggest to use a plastic bin A LOT bigger than the amount of substrate your are pasteurizing <-more space means easy shake.

My spawn ratio is really high, never calculated, but i'm sure it will work also with lower ratios.

Yes a part are SacO2 mycobags, a part are common freezer bags for food (i mean the one with blue milk caps)

I've to make a comparison with Unicorn spawnbags, but i'm sure the oxygenation is far better or SacO2. Unlucky they accept a minimum orders of 1000 bags per time..

Fabio :smile:
