bacteria blues

I've been having bacteria problems characterized by stalled jars, rotten fruit smell, and weak mycelia. i use pf tec on small jelly jars w masking tape. i sterilize my needles w a propane blowtorch between jars. frankly, im at a loss. at times the method is almost flawless, on other occasions, bacteria is rampant(80%). id really appreciate any suggestions to prevent this. Would H2o2 in the syringe or jar work?

H2o2 would hurt. It damages mycelium helping contamination out.
Pictures or explanation of everything start to finish would help

Agar for syringe cleanup. Every project should be started on agar anyways. Also why masking tape? How permeable is it? You need a dry verm layer. That's it. No tape necessary.

Yeah, give us a detailed guide of your sterile tek, spawn prep, and inoculation. Procedure. We can help you out but we need more information.

No pics needed then. Just write out your process.

Then explain your inoc procedure. Please tell me you don't use alcohol to wipe your needle.

I'm not asking for your sub ratios. I'm asking for a detailed list that tells me your inoculation and sterile tek process.
Can't help you figure out contam vectors if you do not provide this info.

Are you inoculating in open air? This is a contam vector.
You are innoculating directly from spores to grain. This is also a contamination vector. To remove this vector, inoc to agar, then do agar transfers if necessary (most times it's not necessary) and inoc with agar wedge.

Also, 9 times out of 10 when you have bacteria, it's already in your spawn before even inoculating. PCING for 1 he isn't long enough. PC for 90 mins minimum. Use foil over the lid to prevent anything falling onto it, and try inoculating in a still air box or in front of a flow hood.

This is pf tek. No grains and no wedges.
Open air, although isn't ideal, won't be the reason why mass amounts of pf jars are going bacterial. Pf tek sterile tek is balls easy. If you don't alcohol wipe the needle, and flame between each jar, the problem is the syringe itself. Agar clean up and inoculating with LI would be the fix. Besides every project should be started on agar anyways.

Inoculate in a still air box. Keep your jars on a shelf with ambient light not in a box in a closet
PC for 1 hour is fine for cakes.
The last thing you need is a flow hood. Build a SAB

A $5 tote with arm holes cut out is all you need for agar and cake inoc.

Ah, missed the pf tek part. The above info I gave is for grains, but sterility process still holds true.

why have so many people, lately, been thinking they need a flow hood to do agar work?
OP, SAB works perfectly fine for agar work, and everything else.
