How many layers of micropore tape will prevent GE

Hi all,
I read this already: http://www.shroomery.org/forums/showflat.php/Cat/0/Number/13665210 but it doesn't say anything conclusive. Perhaps someone has a definitive answer now?
I am currently using the plastic tek without the verm top layer. I put a layer of micropore tape over 2 1/4" holes on the bottom of the lid, then another on top, then another (in a different direction) on top of that. I didn't want it to come off in the PC.
I will have to wait and see if there is enough GE to enable the myc to start growing, but I am curious if anyone has experimented with layering it like I did.
Is there a point at which too many layers blocks GE?
Cheers in advance,

think of GE like farting lol. if you wore 4 layers of pants you probably wouldn't smell anything. so ya, you could use to much. I'm sure 1 layer of micro pore tape is plenty. you're not letting air in you're letting gas out. I just farted and it stinks....gas exchange

HAHA cheers mate. Good farting analogy. I am about to take off the tape on the top, leaving the lower 1-2 layers there. I read others have gotten by fine with 2 layers, but 3-4 layers may be pushing it.

no need for verm layer and tape, and no need for so many layers of tape. all that will equal no GE.
Two layers of tape is fine. I dont see why people go crazy with layers that dosen't solve anything.
i make it all real simple, i use self healing injection ports and a syringe filter.
Ive never had one grow get contaminated, except my second PF cake which was not PCED and it still fruited. Didn't have the ports and filters back then, just good ol verm.

syringe filters are for lc's and don't get enough ge for cakes/grains

i'd use poly for grains (if u were standing in walmart right now and had to choose). cheaper to get a whole bag and use it for next 6months-year on grain jars, agar lids, or mono tubs. if u already have the micropore, 2 layers probably. theres an older thread floating around where they zoomed in on a piece of micropore and it was not dense at all. I'm sure u could find it just type "micropore filter" in search engine. i use it on the pasty agar pp5's tho with great success, so

Quite easy to find out, tape a electrical tube shut with just one layer on one side. Try to blow trough it. Put a second layer over it, and you will find out that shuts it almost entirely. I think that happens because the sticky layer closes the pores on the first layer. So I would not do more than one layer.

I just did 4 layers on a pen tube and can still blow through it 
I have some pretty powerful lungs though.
I have a couple of jars with 2 layers of micropore over an sfd (1/4 inch hole) and one layer under the lid. I just took one layer off the top cause it does seem like colonization is moving a little slower than the sfd with silcone.

That's because you put pressure behind it.
Pressure does not build up in our jars.

Yeah you're right on the money! 
No more double layering micropore tape for me. I guess that's why I've seen sandwiching micropore:tyvek:micropore being recommended.
