Folding bags and contaminants pathway

I fold like this. Front and back and that's it. Sorry, hard to explain. Then tape a little to hold bags in place. I cannot get tyek sleeve.
As I understand, contaminants only dropping straight down and cannot "drive" left, right, up and down if you let your PC to go slowly to 0 PSI.

Wow. How many quarts in 1 bag? 4? 5?
I just fold mine around the bag so that the bag sits on the flap to hold it in place instead of tape. I wouldn't want to remove tape from bags in a sterile situation.. dunno maybe its just me

Folding sub bags is fine. I wouldn't fold grain bags though. When cooling the bag will suck in air through the opening in the bag. Which could pull in contamination. For my grain bags and after I spawn to my sub bags, I use the monoprice cable ties to seal my bags. With the bags sealed any air that is pulled in while cooling must come through the filter patch. I use them after spawning because it is easy to release the cable tie and push out all the air and reseal. They can be used in a PC without a problem. An ounce of prevention is worth an LB of cure...

I just wrap rubber bands around mine and fold the top flap down so that the filter patch is inside of the fold isnt exposed to water in the pc, then put a rubberband around it I get about 4 to 5 uses out 1 band. Also you dont need to fill them to the top this will allow room for you to fold the bags down. I pre seal my bags also and open and reseal them when adding anything. I dont like to poke and hope then cover with tape.

If the rubber band works for you that is cool. But the releasable cable ties last much longer. I bought a 100 pk 3 years ago and have not had to buy any more they last a very long time. They are also much faster and seal better than a rubber band ever could. I seal a bag in about 1 second. I actually did buy another pk because I find so many uses for them. I have them all over the place.
The filter patch on your bags should be made of something like Tyvek and that makes them water repellent. I get mine from...

My point is there is no need to fold the bag over the filter patch.

But as I think those cable ties allowing tiny little (like a needle) airholes? They cannot make full seal, or? Do you have any picture?
What about sealing 0.2 micron bags? Or maybe even vacuum and seal before PC cycle?

The bag is twisted before putting on the cable ties. I get no contamination doing this method. But if you don't feel comfortable using them, by all means, use another method. But if you want a faster cheaper more reliable method then try the cable ties. I do not own stock in the monoprice cable tie company. So I have no reason to say they work so well other than they work so well.

I can say I tried and use the same cable ties he uses. They work well. I do not have contamination problems at all.. And my bags get moved around while zip tied, outside. So they "take a beating" what with the wind and being outside. Whether it is the best method? But compare $5 against the cost of a sealer and everyone says the cheap sealers break and just don't work well... I wish I had ordered another bag of them actually.

Oh and.. I don't seal my grain bags before. I do PC them. I only put approximately 2 quarts in there.. That's 2 quarts dry sized but fully soaked and drained per bag. Not sure what size it is wet, because I only measure 6 quarts dry and then split it 3 ways after the soak and drain. I run 3 bags. Why? in case I get 1 or 2 bags that contaminate I will have back ups. So the extra cost of grains is the cost of security. I would rather spend pennies and know I have good spawn when I need it than need it and not have it. Which is also why I might tend to spawn heavy.. I have it so I use it. Although, lately I have been trying to use less spawn.. but now I have spawn out my ears from the leftover. And can skip making spawn some weeks. 
I PC my 3 bags inside. Let it cool down over night then drag the PC outside and open it up in front of my flow hood where I noc it up. And then seal the bags... I do not have contamination issues at all. And my 3 bags are floating in the water when I start the PC.

Damn, and I already order 2000 pcs 0.2 micron bags for substrate (pellets and bran) and 500 pcs bags for grains.

That is what I use for spawn and sub bags with no problems. But like I said above I don't pre-seal the bags.

Interesting, I would guess they have the same airhole like folded bags. But if you two guys have them with success, then I'll take it. 
When sterilising, do you just block top of the bag with the other bag? You stack bag on bag?

Yea. The filter patch is on there. I had taken the picture from the opposite side it is on. It is right below the zip tie.
When PC'ing I used to use quart jars to keep 'em separated and the folded parts folded when I used less grain per bag. Except the 2 center bags I laid 1 on top the other. Just folded the bag around just like you see all the substrate bags in the videos floating around. If you fold the folded part of the bag up on itself so that the loose part of the bag is tight on itself and thus forming a sort of tight seal and then place a bag on it then you will get a popped bag and get to clean the melted plastic from the PC.. So just fold the bags like you see all the videos and pictures of everyone folding sub bags and you will be fine. Even if there is a lot more bag to fold over and around the bag because you put less grains it it and then put another bag on top. That said. Right now I am placing 2 bags on the bottom(which float in the water) and then 1 bag across those in the center of them flap down to hold the flaps from the 2 bags down.

That's not true, I have nine on my shelf from last month. I've been told other bags are better for substrate though, but that .2s would probably still work for substrate bags.

We just went through this in another thread so I'm not gonna re-hash here, but yes they can have problems bursting if you seal them before PC cycle. It's nothing to do with the filter patch, the .2 are fine, you just shouldn't seal your bags before a PC cycle or they can burst. If you cram it full enough you might get lucky but I wouldn't run that way
