Excellent information. Thank you all very much for your input, it is much appreciated. I believe my FOAF will be starting a bag project this weekend.

Thanks again! :bow: :bow: :bow:

Do you seal your bags before or after you PC them?


Why do you do it that way?

as the bags heat up
the gases trapped inside expand
and need a way out
else the bags expand like balloons,
touch the metal sides of the pc and melt
or possibly even block the escape of steam,
causing over-pressure and possibly an explosion.

If you don’t seal until after, how do you secure the bags for PCing?

i roll them up and use a rubberband, which allows expansion as needed
but seals as it cools.

If I am using bags with vent patches, does that change the answer to question 1 in any way?


What Impulse setting (surprise…they have a knob) do you use for polypropylene spawn bags? Do you also wish the knob went to 11?

i use setting #6,
the 'trick' to a good seal is to hold the sealer down firmly ~20-30 seconds AFTER
the heat kicks off, so the melted plastic fuses then cools.

Do you double seal?

i actually triple seal.

Do you use injector port bags or tape/glue to seal the inoculation hole?

silicon adhesive injection port.

Do you reuse your bags?
If so, how many times and how do you clean them between uses?


When you PC bags, do you allow any extra time for the larger volume of material?

yes, the more in the bag, the longer i pc. i've found it's better to have several small bags than 1 big bag.

Have you ever fruited directly from/in a bag?


If so, would you do it again?


This is a stupid question, I know, but do you use the same substrate moisture ratios in a bag as you use in a jar?

a bit less actually as bags do not breathe well.

Were you hoping for another Spinal Tap reference?

eh ?

Have you ever been killed in a bizarre gardening accident?

Cut/paste some info into my growing personal archives...

Thank you very much, good sir!!! :cool:

Oh, and the knob going to 11 and dying in bizarre gardening accidents were somewhat lame references to "This Is Spinal Tap," a most excellent Rob Reiner movie.

Again, many thanks!!!

My spouse is going to be somewhat uncomfortable with four basketball sized projects fruiting at the same time. It’s fun to watch her eyes get big, but after the excitement wears off, she gets the paranoid heebie-jeebies and I hate that for her. After having flaunted so many rules and conventions for so many years, I’ve accepted the potential consequences (lets be honest, the EVENTUAL consequences – it’s all about playing the odds) of my hobbies/habits. This is why I keep a lawyer/bail fund in a safety deposit box, but that’s a whole different thread. The wife still likes to pretend that bad things don’t happen to good people. It’s harder for her to pretend that when she knows a boatload of fungi are maturing a scant few hundred yards away.

Ha Ha Ha. I hear ya there! When I first started this hobby my wife didn't want anything to do with it. Trouble with the law was her concern. Also, she didn't want my kids to find out. Neither did I, really. There would probably be some missing for sure........ If not, they have friends that would like some.
After a while she got used to it though. After a couple samples, I might add.:D

As for your questions, I hope they were answered by the more knowledgable people above.:)
