I made some fermented feed containers I took mason jars put baby bottle nipples as a one way vent what do think
The one way vent is not needed, and it is acutally preferable to leave them open to the room air so they can get inoculated with yeast and bacteria from your air. Also not necessary to have so much water. Most of us mix the feed/water so that it is about the consistency of thick cooked oatmeal. The ferment works just fine when it's thicker, and saves the extra step of straining it. Check out the FAQ in my signature re: FF.
two lids per jar. one lid 1/16 hole, one with a hole that the lip of the nipple just fits (the ones I used were 1 1/2 inch) the one with a 1/16 on the jar first, then the nipple lid next, then the outer ring
I figure the oxygen in the air could cause mold. From what I have read mold is not good. I do a three day ferment and the gas build up (co2) was popping the lids
