im getting that green mold in about half of all my jars. im using rye berries and doing grain transfers. im doing the transfers in a room that has a flow hood running and im spraying my self with lysol and before entering the room. im using the filter discs from paul stamits site.
do the dics need to be sprayed with lysol? any help would be great. thanks.

i dont think it would hurt to spray the discs, specially if there old. just check and double check for any descrepencies in your sterilization, and check for the weakest link in your steps to find were you might be lax or when in your proccess the contams are creeping in. My guess is that your getting contams during the grain transfers since this is when they seem the most prone to contams. other than that i dunno...maybe agar or snagletooth or carlos have some good ideas for you.

do you do it directly in front of the flow hood?
how long do you let your hood run?
do you have one of these http://store.pksafety.net/stancov.html and one of these http://www.alerg.com/page/A/PROD/NEW/MSK1000?
Do you spray the air with oust befor you start?
how long do you pressure cook your grains for?
Do you let your grains soak befor you pressure cook?
Do you have the lid on like this Lid filter ring or filter lid ring?
some times puddles can get between the filter and lid. this is why i took agars adivce and used only micro pore tape found at any pharmacy.

im doing the transfer right in front of the flow hood, and letting it run for about an hour before i go in there. i also spray the room with lysol about 5 to 10 mins before the transfers.
i dont have a tyvek suit but i do wear and mask over my face.
i do NOT soak the berries bfore i PC them, and im PCing for 1hr15mins at 15psi
my jars go filter, lid, ring.

I like how the mask shown by clicking that link has an unfiltered output vent so that you exhale bacteria all over your cultures (the little circle with the 3M logo in it)

soaking the grains does two things:
1st, it establishes a good balance of water, and makes it easier than wondering how much water to add to dry grain.
2nd, it causes mold spores and bacterial endospores to sprout, and since the germinated spores no longer have their thick cell walls, they are more easily KILLED!!!
KILL CONTAMINATION, MOTHERF***ERS!

It allows endospores that can survive pressure cooking to germinate and thus allow them to be killed during the pressure cooking.

there could be mold falling from your hair. I had that problem on my first try and then took a chance that it was my hair and cut it off and no more contam. problem. and then I grew it back out again and then I had the same problem starting all over again. And the second thing is, Lysol is a great thing but you cannot depend on that to kill all the grems and bact. in the air. you need to mix a rubbing alcohol, distilled water mix in a spray bottle at a ratio of 15% alcohol and the rest warm water. Spray the air and your hair your hands your clothes, your shoes, anything that you can think to spray, more you spray the better the chances are that you wont get contam's. You might not have had that batch of jars sterilized good enough. There are just too many factors.
