spawn bags issues

This is a c/p from tnf...thought I ask my question here as well :Im having a few issues with the grain jars. My PC is kinda small and I can barely do 3-4qts of rye in jars. I do have some filter spawn bags, however I cannot find tyvek in my parts nor do I have laminar flowhood or bag sealer. The bag sealer I can get (although I did already kinda go over my budget for this hobby). I have some easyfelt sheets that I was thinking to use instead of the tyvek in the bags while PCing. However my main concern is with the lack of the flowhood. Assuming I open my bags in a SAB right after I get them out of the PC, they might move a lot of air around, thus defeating the entire purpose of the SAB. It would be really convenient for me to find a workaround to this tho.
Any suggestions ? Can I use easyfelt ? Should I get the bag sealer ?Will it work in a basic SAB?

my PC only fits 4 quart jars. make masters with 4 and then while those colonize PC some quarts through the week and g2g them. a spawn bag will help you out a bit but you really need a bigger PC

Tyvek sleeves are a pointless fad. Using EZfelt on your bags would be just as silly.
My impulse sealer sucks so I usually ziptie bags closed.
The nice thing about having a small workhorse of a cooker is faster cool down and mine always fit nicely in ye ol' SAB.

Indeed. Get the bag sealer, or a flowhood. Without a flowhood it would be forgotten about G2G'ing bags inside of a SAB. Rather, without a flowhood, bags are sealed pre inoculation, and inoculated with a liquid inoculant through the bag in open air once the substrates cool to room temps.
Ignore bad advice above stating that tyvek sleeves "are a pointless fad". Tyvek wrist sleeves are a bullet proof method of keeping bag substrates sterile during the return to atmospheric pressure inside of your PC. Best to have a flowhood to open sterilized bags in front of, though, when utilizing & employing tyvek wrist sleeves as filtration material.

Sorry, but the only bad advice being tossed around is that Tyvek sleeves actually do anything.

Exactly. Because Tyvek is anything but a "bulletproof" method.....
You can sit around and stick shit in your ear all day long, but thats not to say its a good idea.

Thanks for the replies. I'm not going to get a flowhood anytime soon, so I can take the liquid inoculant route. My only issue is how to seal them safely after the PC. I don't see how they could get contaminated inside the PC while cooling off, however I figure that as soon as I open the PC I should move fast and seal the bags. I also have some ikea clamps that i can use for sealing (there is a thread around here about said clamps, only mine are smaller so I need to clump up the mouth of the bag a bit). Also pretty sure my PC doesn't fit in my SAB. It's a weird model, high but not wide, good for steaming vegetables tho

I've done a lot of grain bags and what I do is use clear package sealing tape to seal them. I seal them about 90% of the way before PC'ing and the sealing tape (clear) seems to survive the PC'ing fine. That way , there's just a small part (maybe an inch) open that I quickly tape over when I remove the bag. I remove it fairly hot, maybe a half hour after pressure has returned to zero and then tape to seal it 100% goes on within seconds. Never had a grain bag contaminate doing it this way. I sterilize for 2 hours in the PC. Definitely use a syringe to inoculate the grain with LC or LI then massage it around really good. If you do this, you probably won't have to break it up and shake it around again. Fully colonized within 10 days unless your inoculant is no good. The bags never get opened and contam rate will be very low.

So completely seal your bags before you PC them, once they've cooked and cooled then inoculate directly through the bag. Just make sure to patch the hole you made with the syringe. A sturdy tape should work fine for patching a small hole.
Your clamps should work if they're PC'able and hold tight. Zipties can work to. Make sure your using a proper sized filter patch bag before trying to preseal and PC to avoid blowouts. I've been presealing .5 micron bags with good luck lately.
Lots of good info about these procedures if you just search for em.

You can seal both .2 and.5 micron bags beforehand, I do it all the time. The trick is to make sure you get all the air you can out and using masking tape to hold the top of the bag folded tight, bring the pressure up and down slowly. Never had a blow out with a .2 or .5 micron
