Thanks for the tech.Would this method work with a spore syringe? Also curious what you used for sub? I'm a newbie and trying to figure out which way would work best. TIA!

Thank you very much.

Also, after the bags have been inoculated, do you put them in the dark or indirect sunlight or what?

Hi,
I just wanted to double check the 140 ml amount-that's a hell of a lot-is that right?
Also, you say to pc for 3 to 4 hours, but you don't say what psi?
Thanks!

The new bags should be treated exactly as the old bags, except they can be, and should be, sealed prior to sterilization.  They also don't really require to be hung up with clamps to inflate since the patch breathes so easily one can just sort of pull on the top to inflate them.  The new bags are superior to the old ones and really have no drawbacks other than maybe price.

I wanted tech advice on how to properly sterilize the "new" autoclave bags in a PC as you have.
These bags have the white co2 filter and the self healing injection site.

I have read the all post on the older bags and wondered if the process stays the same?

It would seem with the new bags you could put the substrate in first and then seal the top before PCing?

It is not the first growing experience for me with the older bags. As they were already PCed with proper substrate and sealed before I received it. (2004ish) However it will be the first I PC my own substrate and seal the new bags. Yeah for me!

I have a vacuum food sealer with either (not sure which one) a heat strip or vibration strip built into it for sealing after vacuum. (But will work)

Should these bags be prepared or arranged differently while PCing with out water or steam leaking through the white co2 patch?

If I over looked another post on this subject I apologize in advance.

Thanks for any help,

The Ascension

This is brilliant, thank you for sharing the wealth of knowledge.

Can you clarify, I know you said that each bag can be injected with a FULL 140ML of liquid culture, that is the correct value right? Thanks.

infinitesimal, the main difference lies in time adjustment.  The foodsaver machine, which I also own, does not allow one to adjust the seal time up to accomodate the type of plastic that these bags are made of.  It might seal them but not very well, especially not well if they are at all damp like fresh out of a cooker.  Having a real sealer is worth the extra $30, believe me.

The New Presealable Spawn Bag from SporeWorks

I finally was on my last few bags on the old SporeWorks large spawn bags, so I ordered the new presealable bags.  I also compared them side-by-side with the older type of spawn bags (which were about 25% cheaper).  

Caliper testing revealed that the new bags are not thicker than the old ones (both are about 2.5 mil).  The newer plastic does, however, seem stronger and is noticeably clearer.  The big difference is in the filter patch.  Not only does it look totally different, it also acts differently.  Following the above technique, I found is that the self-inflation hang-the-bag-up step is not needed with the new bags because as you try to kneed them even for a minute or two, the filter patch is so permeable that they will inflate right before your eyes!  This is very different than the old bags which needed an hour or so hang time to inflate.  

So, what about the self-sealing thing?  I did have not tried it yet.  What I do know is that ANY bag, presealable or not, can blow off a lot of steam and pop open if one doesn't cool the cooker slowly and if the cooker is heavily loaded.  The new bags definitely have a patch that is far more permeable, but even these bags, I am certain, have their limits on what they can tolerate in terms of letting out steam.  If you don't want to take a chance, I always recommend dropping the pressure cooker to medium-low to low heat for about a half hour before cutting the heat entirely when doing any heavy load to prevent the bags from blowing a lot of steam off too fast as they cool (which might pop it or mess up the organized laying of the flaps if not sealed).

Hi, interesting tek. I was just wondering if there is a difference between an impulse sealer and a food saver (vacuum sealer)? If there is what is the difference? Can you use a food saver in place of an impulse sealer? If not, how come? Thanks. Sorry the other one posted black.

I was considering another way to hang the bags without using clamps:
