question regaurding sterilized jars and filters

im going by the "lets grow mushrooms" DVD for my jar setup.
ive seen teks on here use both tyvex and polyfil for filters on the same jar, but in RR's DVD it says either or. so for about 12-15 jars or so, whatever i have already sterilized, i just used polyfil as a filter with no tyvex. i covered them in foil and then PC @ 15psi for 60 minutes.
the jars are cooled down to room temp now, so i went and checked them. some of the polyfil seems slightly moist, not wet, but there is some moisture on the poly fill. is this OK? do i need to get them to dry? or did i fuck up and is this going to cause contamination? theyre in a sterile environment ATM...

you dont use either for brf jars, those are for grain spawn jars. 
pftek brf jars only need the 1/2" verm berrior and the 4 inoculation holes in the lid for Gas Exchange. you can put micro pore tape ocer the lid holes after you inoculate for added protection but its not needed if you dont move your jars around alot checking them all the time. 
if you use micropore tape you can check them all you want just dont upset/disturb the verm layer. 
but if your using grain jars then you need one hole covered in tyvek or stuffed with poly fill but synthetic filter discs are best (check the filtration link in my sig) for gas exchange and one hole with a injectin port or silicone blob filled hole for inoculations.

pf tek doesnt suck.
but damp polyfil is no biggy.
nothing will germinate or colonize on/in polyfil.

sure did. theyre just slightly damp/moist.
im sure theyll dry off slowly.
gettin grain ready and PCing 50 jars is a lot of work...
PF tek sucks in the fact that, well, i find it lame lol.
