You don't tape the holes up, you put foil over the lids to prevent water from going inside. Then remove the foil after cooking, no tape especially for pf style cakes.

Yeah, use foil. You can save the foil covers and reuse em.
Tape becomes a pain to clean off.

I used foil. The tape is only used to protect the jar while in the PC. After the PC the tape is broken when inoculating with a syringe. I use a dry verm layer as a filter for the PF jars.

Next time, make sure the jars are totally out of the water. It's the steam that sterilizes, and it won't get your substrate wet. RR

If u use tyvek as a filter u don't need to bother placing foil on the lids. Tyvek is impermeable so, use foil when preparing PF Tek jars, if you're preparing grain jars, there's no need. I never had a problem.

Main Entry: per·me·able Pronunciation: \?p?r-m?-?-b?l\ Function: adjective Date: 15th century
: capable of being permeated : penetrable; especially : having pores or openings that permit liquids or gases to pass through <a permeable membrane> <permeable limestone>
Notice it lists liquids or gasses. So if something is permiable to gas but liquid or vice versa, the difference in meaning between permeable and impermeable would be defined by context.

By impermeable i meant that gas can pass thru, but water can't.
