Small volume straw pasteurisation tutorial [not realy a growlog].
#2252057 - 01/19/04 03:39 AM (20 years, 14 days ago) |

Put the straw and/or dung into an oven tray thats deep enougth to fit the amount of straw and/or dung required.
Then pour warm water over the straw and/or dung, until its deep enougth to submerge the straw and/or dung into.
Submerge it by placeing something onto it thats heavy enougth to sink it. I use wall tiles for this, but you can use a variety of items. Then place in the oven at 170?F / 75?C for one hour. Don?t exceed 170?F / 75?C, the temperature should be held stable by your ovens own thermostate. After 1 or 2 hour take the baking tray out and place it at an angle that allows it to drain of excess water, 1 hour is normally enougth. After it?s cold (might take several hours) you can spawn it.
Once drained its ready to use.
You can then move the straw to another tray, and spawn it, here i used 500ml of millet spawn.
You then mix the spawn and straw together, but dont compact is too much, just lightly firm it. And i always add a thin layer of unspawned straw to the top.
This is the filter method i use (click here)
nearly colonised --------------------------------
Now the straw is fully colonised, it's time to case.
Here I'm using, Multipurpose compost(untreated, unfertilized, peat free) and Verm 50/50 with a hand full of crushed oyster shell (the sort you find at farm stores in the chicken feed section) Mixed up and nuked in an 800w microwave for 2 mins on full, shaken and nuked again for another 3 mins on full, then cooled.
Then a layer is spread over the straw. I like to pour it on around the edges first, as the shrinking straw creates an air gap there. This i do so that it fills the air gap, and sits a bit thicker all around the edge(about 1 to 2 inches), making it less likely for pins to form there, and herds them towards the middle of the casing. Then I give it a good spray with sprng water and h2o2 rebag, and place back into the incubator for a few days.
-----------------------------------------------------------
The casing layer is now colonised enougth to fruit from, a little too far actually, as there are pins forming in the lower left section. This is due to light pollution.
So into the fruiting chamber, next update soon -------------------------------------------------------------- Pins

Nice Pics.
Cool idea.
The mask is for filtering correct? Do you just poke a bunch of holes underneath of it?

Yeah, i just glue it on, then cut out the bit beneath the mask. Before i was glueing on strips of tyvek, but i thought id give the masks a try. Hopefully they'll do an ok job.

i noticed you use wbs to spawn, can you use PF Tek style jars for the same thing?

Yes, you just need to break them up or grate them. I much preffer millet though, as its falls apart with ease, with limited mycelium damage.

Great idea! I find pasteurizing straw in a big pot to be such a chore. Shame my ovens lowest temp is 90?C though

When you spawn to the straw like that, I noticed the wbs just sitting on top, did you mix that into the straw layer? Also, after that point do you just place back in the incubator? How long does it usually take to incubate something of that size?

Yes, I mix it in, that picture is just to show how much really.
After i mix it in, i add a thin layer of unspawned straw to the top, then bag it, and incubate. Normally another week or two to colonise, then case, bag, back ikn the incubator again for 5 days, then fruit

What do you think the best way to break up the PF Tek style jars might be? You mentioned about grating them, which I have seen done in other threads, but to what size do you suggest? Largest?
The other ways that i've broken them up has been to place them in a large zip-lock style baggy and just use my hands through the bag to break them up to malt ball size cubes.
What might be your handiest way?

I would stick to using a zip lock baggie to break them up in. I've also seen the grater used, but seems a bit unclean to me, if you were to do that, I would use largest holes on the grater.
I've never actually done this, as i moved over to millet quite quickly.

I've never had any problems breaking BRF cakes or millet up with my hands (wash your hands with anti-bacterial soap first) although I moved on to millet after my first grow as it's FAR superior to cakes.
BRF cakes are a waste of time IMO.

Will you post the results of your project? I'd be interested in seeing how much of this small over pasteurization can yield.

No problem, I'll keep it going till the last fruit. At the moment, its about 70 % colonised, so no long untill casing time.

Yes, I love the smell, reminds me of damp woodland 
A little update uptop, casing colonised and into fruiting chamber.

Thanks, these (click) mex b were grown using the same method, same temps ext. Only difference was the spawn, in this thread i used millet, in the linked thread i used perrenial rye grass seed.

Whats the logic of adding the thin layer of straw? How thin?
How does the filter thing compare to foil or plastic covers? Did you have problems with nasties falling in during incubation? Is that why you started using the filters? Ive been tryin to figure out a way to easily cure that problem myself. I was gonna buy a hepa but this may work well.
That casing mix has no nutrition. correct? Does it change color when it dries? Im lookin for a simple casing recipe.
Thanks

I add the thin layer of straw over the mixed spawn so that once the top is colonised, I know the that the deeper substrate is also well colonised, rather than the spawn at the surface just growing faster due to better air, and making it look as though the whole bulk tray is ready.
I find the filters to be good, and speed up colonisation a little, due to better air exchange, though just the bags alone seems to work ok too, just not as fast.
I havent really had many problems with nasty in bulk straw mixes, but i have a clean room with a hepa and carbon air filter were i do all the mixing.
The casing mix i use has some nutrient value, as i use multipurpose compost instead of coir, but not a lot of nuts still.
Its 50% multipurpose, 50% verm with a hand full of oystershell. I mix it up, add boiling water untill its as wet as i need. Nuked for 2 mins on full, shake, and nuke again for 2 or 3 mins on full. Colled and used.

Its a massive help, I dont regret the money spent at all, in fact, i think I'm going to spend more on a better hepa (larger)
I do all my work in a small room I have converted into a lab. Nice and white and washerbal :-) Turn the hepa on for an hour before work, and it cleans all the air in no time.
