DIY spawnbags (pictorial)
    #562556 - 02/25/02 12:38 PM (7 years, 8 months ago)

Grass seed (2 liter) and water (1 liter) combined in a polyproylene bag.




Bag is pulled thorugh a polypropylene ring (cut from a big syringe)




Bag is folded back...




...and secured with two rubber bands




The openeing is stuffed with polyfill.



And this is covered with aluminium foil to prevent it from getting wet in the pressure cooker.




Bags after autoclaving (2 1/2 hours)




These bags should be inoculated with liquid mycelium since they cannot be shaken.

Great post UNA.....Can?t wait to see your results. Would it be possible to leave more room in the bag for expansion and shaking instead of pulling it so tight? Could someone use this tech. with filter patch bags if they did not have a bag sealer?

Ordinary oven bags will work. Be careful the side of the bag doesn?t touch the pressure cooker or the bag may still melt. If your PC is small, you can use cotten (no nylon!) string to tie the bag into shape.

Uno,

Just a suggestion.

Rather than using polyfill, if you can find a large Tyvek mailing envelope? Simply, cut it up into squares or circles & use it as a gas permeable filter in place of the polyfill, held in place with rubber bands. Tyvek will withstand autoclave or PC temp?s & works well as a filter.

Also, at most hardware stores, one can find high temp plastic hot water plumbing PVC pipe in diameters from 1/2 to 2 inch. They come in 8 foot lengths & are very inexpensive. You can simply hacksaw small lenghts to use as a ring neck for the bag top. That way you can make as many rings as you wish & bigger size than a syringe, for very little $$.

The Racoon tells me this works fine.

    #563927 - 02/26/02 03:21 PM (7 years, 8 months ago)

that?s exactly what i did this morning What a coincidence.

Instead of using PVC pipe i used special cardboard rings that withstand autoclaving.
Inoculation was done with 50 ml of mycelial suspension injected with a syringe through the tyvek filter. The hole was taped.



Here?s a picture of an (almost) fully grown bag, two weeks after inoculation. Some small scattered sclerotia are already starting to form.

Sorry to sound like a newbie, but I?m not familiar where one would get a "polyproylene bag". I think you meant polypropylene bag, but even at that, do you know of a place where such bags could be acquired?

Thanks in advance, this is awesome.

Go to the supermarket and look for oven safe baking bags. They are usually in the same isle with all the other baggies.

great! So fast after so much time. What mushrooms did you grow like this?
Do you grow them always vertically or also horizontally?

I have autoclavable bags from Mycosupply, but I ordered them like 2 or 3 months ago when they didnt yet have filter patches. I guess I can just use tyvek after innoculating in multiple spots

b/c of the polyfill filter, if you happen to find a syringe with a adequate
long needle, you can inoculate through the polyfill filter.

otherwise, through the plastic and seal with hot glue for example.

or g2g though the pipe (i wouldnt, b/c when replacint polyfill youd
sure get urself some nasty contams)

uh jeah, btw, 800post :blush:

I notice your bags are packed very tight, is this needed for some reason? Can I use less grain and make it so I can agitate the bag to disperse the mycel? And also could a less full bag be fruited like a mycobag?

where do i buy those bags at? is it a turkey bag?

its a turkey bag jeah.
they are packed tight since una obviously wanted to cram in as much
grains as he managed to -> maximum efficiancy.
you could fruit inside, but you would have to use way less grains,
in order to provide adequate 'space'
and you can also use less grains in order to be able to knead it to
distribute the mycelium.
