Quote: Hot air is less dense than cool air, and so as the PC cools it will "suck" air from the surrounding area. Autoclaves have compound gauges and DO NOT "suck" air back. They will eventually enter into a "vacuum" and as the unit cools, negative pressure will rise UNTIL the user opens a relief valve. If you use proper gas exchange/filter ports, this should introduce little to no issue. Something as simple as a polyfill ge port should keep everything out. I think what cronicr is explaining is that IF you start your plastic jars @ room temp, with no condensation then PC and allow to cool, that there should continue to be no condensation once it gets back to room temp. Glass jars seem to work no matter what process. I have yet to do anything special with the glass jars. PC while hot/fluid etc. I have done it a few ways with glass, and none of them have condensation after a day. HOWEVER, I have noticed that the metal lids on glass jars produce slightly more condensate than the plastic lids. All of which vanishes after 24 hours. -------------------- Grain and seed prep:PrimalSoup's Simple Rye Grain prep tek 04-09-2011, TranscendingLife's Simple WBS Prep Tek 04-10-2012, FrankHorrigan's WBS Prep Tek 11-20-2012 Monotub teks: Ohmatic's Monotub Tek 02-08-2006, TranscendingLife's Monotub Tek 05-24-2011, FrankHorrigan's Bulk Spawning Tek 12-25-2012 Straw Is better than coir:RR's Straw Prep Tek 06-07-2010 Agar:Stro's Cleaning and isolating on agar thread 06-17-2013 PF Tek:Shea25's Pf tek done right TEK Ban Lottery: Enter To Win!
