Also looks like a good way to seal spore prints.

Best prints are IN A SPOREBAG, follow along.

Print on autoclave bag material (about 6 to 7 inchs square).

Once print is laid, cover dry print with another square of same (alc swabbed first & allowed to evaporate).

Double seal all edges with IMPULSE SEALER.

When you want spore solution.

In aseptic conditions, G/B, or under flow hood.

Swab outer bag with alc.

Have 20 CC (or whatever size you prefer) sterilized syringe full of "sterile" water, ready.

Pierce autoclave bag material with syringe needle on a CORNER.

Inject 20 CC into sealed square.

Reseal with impulse sealer (or with good tape - if you must).

Massage bag to mix spores into solution.

You now have bag of spore water to extract from & use whenever you please.

Store in refrigerator.

Extract with sterile syringe.

When fluid level is LOW, refill & reseal (as above).

When you're finished, do you mind walking us through your mini-sealer construction? Are autoclavable bags signifigantly cheaper than the mycosupply bags with tyvek filter (~$.70 each)?

LOL............... The market-place is COMPETATIVE:

Simple INOVATIONS often make MILLIONAIRES:

Below is a commercial grain "spawn bag" incubation run.


Spawn bags are made of Polypropylene (PP). PP is a plastic material that is heat sealable, that is when two pieces of PP films are heated to melting temperature, under pressure, they dissolve into each other, and when cooled the two pieces are bonded permanently as a single piece.

PP resists temperatures of sterilization (about 256 degrees F). It is also one of the cheapest of all plastic materials.

The fact that TYVEK works effectively as a microporous filter on glass spawn jars is well known.

Since it can be impulse heat seal bonded to PP.... that SIMPLE fact will lead to cheaper individual and/or commercial grade filter patch spawn bag production in the multi-billion dollar world wide mushroom cultivation industry.

Simple economics, if 2 PP spawn bags of equal size & quality were for sale, and the one with a Tyvek filter patch was cheaper than the other. Which would YOU BUY. It takes no WIZARD to figure that one out.

They originally meant, how did you build your mini sealer? The one you used to seal the tyvek to the autoclavable bags.

ty agar.

I discovered it with a regular impulse sealer. I am now waiting for a few parts (online order)to build one with. Once they get here I will do a tek, or at least a pictorial.

yes but if you are using 20+ spawn bags a week and pasterusing straw and making logs and shipping to markets.. Is it realy economical spending the time, cuz time equals money making your own filter patch bags? A bag with filter goes for ruffly 15 or 17 cents when bought by the 1000. Im not even going into spawn block production that can top out over 100 bags a week.

All in all I suppose it works well for a noncomercial hobbiest.

$.15-17 cents each, where's this at? Mycobag is $.25 each for 1000.

^^TRUE^^

Also, you cannot compare one size filter patch bag to another - price wise.
