 Coffee filters prevent gas exchange?

Hi,
My question is regarding coffee filters on brf/verm cakes. Recently, my evil twin innoc'd some jars, using the oven tek, and put a coffee filter under the screw-rings on the jars to guard form contamination. Obviously, coffee is not HEPA by any stretch of the imagination, but it seemed like a good idea.
Anyhow, will the coffee filter constrict gas exchange too much for 1/2 pint jars with 4-site innoculation (MMGG)?
Thanks,
-Seiko

Nope, your cool. You don't really need the filter cause that is what the verm is for. I shouldn't talk cause I use them to just a little different then you.
I wait till I see the myc start to grow then I remove the tape and put a filter over the top of the jar.
I found this grow log.
Grow Log
Tek : PF
Strain : South American [SA]
Spores : Came from homemade prints. 36 total jars to be injected.
Substrate :Brown Rice Flour [BRF] and Vermiculite [Verm]
---------------------------------------------------------------------------------------------------
10:15 PM 3/4/03 : Project is started. Jar prep is just putting small holes in the lids for the spore syringe and then taping them closed until inoculation. Tape used is the standard black electrical tape. First batch of jars is mixed. The mix used is 2 parts verm, 1 part water, and 1 part brf. [ This mix is the max fruiting formula by PF.] Mix is put into 1/2 pint canning jars lightly, not packed in, and left it airy. Put substrate in until it reaches the threads of the jar, then add dry verm the rest of the way.
Jars are PCd at 10psi or 240f for a period of 45 minutes. Then jars were left to sit overnight to cool.
8:39 PM 3/5/2003 : First batch of jars injected. (24 jars)
10:04 AM 3/6/2003 : Incubator is running to low 77F. Going to turn it up today.
5:45 PM 3/6/2003 : Second batch of jars is in the PC will be injected tomorrow. Turned up incubator runs at 83F. 86F is the best and if the incubator is 83F and myc growing in the jars is suppose to create a little heat I figure this should work out well.
1:11 PM 3/7/2003 : Second batch of jars is done. (12 jars)
12:10 PM 3/9/2003 : Jars are doing good, no signs of contams
2:54 AM 3/19/2003 : Tape removed from the holes today and coffee filters put over the top of the jars for added protection. Holes were opened so the CO2 in the jars could escape. I gave 12 jars to a friend who kept fucking up. 24 jar?s about 75%done.
12:13 PM 3/22/2003 : Well it's Saturday and the jars will probably be done by the 25th. So it was 36 jars. 12 were given to a friend, 24 done by Tuesday.
10:26 PM 3/23/2003 : 15 jars were done enough to put into dunk. I dunk and cold shock before birthing and after every flush. The other 9 jars have a spot the size of a pea that has to be covered so I'll do those on the 25th.
7:17 PM 3/24/2003 : 15 jars put into the pod. Put in and put a layer of moist verm on top. With geolite I just put the cakes on it. With some other chambers I put the cake on a lid filled with verm. This is done to give the shrooms on the bottom and the top of the cake some added moisture.
The other 9 jars just finished so I'm going to give them a couple more days to make sure the middle of the cake is done.
4:57 PM 3/27/2003 : 5 More cakes birthed today, 4 left going to do them tomorrow or 3/29/2003
3:58 PM 3/29/2003 : Well I lost another cake. My wife's little 1 cake pod made from a 2 liter and a small fish pump and a little geolite used up her last cake so I gave her a SA to grow. The last 3 are in the cold shock dunk.
So the total is 36 jars done all colonized with no contams. 12 given to a friend, 1 to the wife, 23 mine
12:08 PM 3/30/2003 : Last of jars put in
12:02 PM 3/31/2003 : The first 15 cakes are pinning nicely and some have shrooms coming from the bottom.
11:01 AM 4/3/2003 : Things look to be going well.
1:02 AM 4/4/2003 : Took the first flush from four of the cakes. More will be done later today.
10:37 PM 4/20/2003 : Started cutting some cakes in half to see if I can create some new mushroom sites.

You can BLOW through a coffee filter. You cannot BLOW through Tyvek.
Tyvek allows enough gas exchange in grain & WBS jars.
Coffee filters DO NOT prevent gas exchange.
Coffee filters should ONLY BE USED as an external dust cover.
NOT AS AN INTERNAL FILTER.

The verm is there, true, but after a disasterous first-time-out encounter with cobweb mold, I want my evil twin, despite his budget and inexperience to succeed.
