Filter bags
    #15927777 - 03/10/12 12:42 AM (12 years, 10 months ago)

I'm about to buy some bags from this site: http://www.mycelia.be/en/sales-products/e/category/lab-supplies/microsacs , but after reading the online manual: http://www.saco2.com/pdf/saco2.pdf; I'm a bit confused.

Thought maybe U guys could help me out.

Check out the third page of that manual above. There are 2 types of filters:
#1 wide - for substrate production
#2 narrow - for spawn production

So the thing I do not get is... the difference between substrate and spawn production? :ashamed: And why should those 2 have differnt filters?
I know it may sound stupid but I always thought that after inoculation with spore syringe or using a colonized grain as spawn is the same thing that one could call MYCELIUM PRODUCTION or MYCELIUM GROWING...

Or maybe using spore syringe is in fact substrate production and using spawn - spawn production?
Or colonizing grain for intended use as grain spawn is spawn production, and colonizing grain from which fruits would be grown without any further actions but simply by placing it in fruiting conditions, is substrate production? And if so why there should be different types of filters?

So please, let one of U experienced cultivators enlighten me :wink:

Hmm that pdf link doesn't work unless you strip the last invisible character off it - but substrate bags/filters are for bulk growing - it's what you spawn to. Spawn grain gets sterilized & substrate gets pasteurized - different temps & times. So they've designed filters differently for each according to the amount of moisture in each I guess...

One more thing, why not sterilize both spawn grain and substrate? Why substrate should be pasteurized and only grain spawn sterilized?

When you're knocking up jars with spores or live tissue you do it in a completely controlled environment (the jars, in theory), where you don't want any other fungi/bacteria develop, since they have perfect conditions in the jars.
So you sterilize the jars to kill any type of bacteria/fungi INSIDE your jar, to let spores\live tissue get develop over the spawn with no competition (in theory).
Since sterilizing is killing organisms, your wanted strain can develop with no competition (no organisms in the jar = ONLY your wanted organism is in the jar = no organisms to fight for colonizing the jar, easy win).

When you pasteurize your substrate you do it for this main reasons:
1. colonized jars are more resistant to contamination, which means it can survive, develop and do well in un-sterilized substrate.
2. you try to reduce the amount of "bad" contamination sources (molds, bacteria) but still keep the "good" factors of the substrate (other sorts of bacteria and of course nutrients in the substrate).
3. sterilized substrate is heaven for molds and bacteria, since they have no other life form to compete against (that's why you take extra caution steps when dealing with jars), but pasteurized substrate have SOME organisms in it, which would hold back the bacteria\molds a bit until your already colonized cakes the over them.

That's how I understand sterilizing vs. pasteurizing anyway...

the 2 types of filters are
a) for spawn, they let very little gas exchange happen
b) for substrate, a lot more gas exchange takes place, along with more evaporation. It really matters a lot more for edibles than "others"
    It has to do with the actual filters, one is a lot tighter than the other(the pores are smaller)
