Coffee Filters and Air Exchange?
    #4174194 - 05/14/05 12:49 PM (13 years, 11 days ago)

I have been doing some WBS jars lately. I use 3/8 inch holes filled with polyfill for air exchange. I have used a coffee filter over the top of a few of my jars, for an extra dust barrier. The times i have used the coffee filter it seems to have slowed myc. growth and made it less strong looking. Is this possible? I always thought that the coffee filters did not inhibit air exchange at all, but maybe im wrong. The times i didn't use coffee filters the myc. seemed to grow faster and stronger, but also the jars seemed to contam easier.

Has anyone had experience with coffee filters slowing colonization?

I have some WBS jars now inoculated with cambodians that seem to be going fairly slow. They have coffee filters on them too. I thought cambos. were supposed to be very fast colonizers, but i have had Golden teachers that colonized quicker than these.?

I doubt it....Coffee filters aren't that thick....

Have you done anything different in your procedures?

Or have any of your environmental conditions changed?

No everything is the same, except i used Roadkill's 3:1, WBS:Water technique. I just put 1.5 cups WBS and .5 cup water into the jars and PC'd for an hour.

I only incubate at about 75, and it usually takes 7-10 days to really start colonizing good. It's only been 8 days so maybe it's about to pick up.

If you are not soaking and/or simmering the water:wbs ratio can vary slightly. You can start at 1:3 and tweak your ratio from there.

Im not saying this is your particular issue, but it is possible.

I have used WBS for some time and I actually use tyvek and 2 coffee filters and have not had any problems. Most quart jars colonize within 2 weeks max.

Paper coffee filters will not impede GAS exchange, even double or tripled up. They are to porius to do so. It must be some other variable.
