Narrow Jars go slow too...  -

I just wanted to know if it is normal for mycelium to start slowing down inside the jars. For a while it was doubling in size every 12 hours, then every 24 hours. Now it just seems to be creeping along. Is this normal? or is it because it is about to stall? What should I do?

sounds like its fine, sounds like you keep a pretty close eye on the jars. give it some time and some extra heat and you should be fine. what % is it at? you doing pints?

Do not open them. If you have holes punched into the lid, make sure you uncover them and just turn the jar upside down. The mycellium may slide down to the lid forcing all of the CO2 to come out and when you tilt it back over, that will suck new fresh oxygen back into the jar. I am sure you know about the Sterility. One of the most interesting ways I have heard to clear the air of contams, is to turn your Oven on the lowest setting. When it is done preheating, open the oven door and do all of the turning, or if you decide to loosen the lids to let some air in, while holding the jar about halfway into the oven. The heat kills most of the air contams. Just my two cents.

The heat rises and keeps airborn contams from falling into the jars

If it was the heat, we'd have to be working inside a boiling pot of water :)

if the jar's holes are taped, remove the tape now.

Oh, sorry, that makes more sense.

My jars have also slowed down, but are still creeping along. I can't get the optimal temp for incubation, so raising the temp artificially isn't really an option. Would I benefit from taking off the tape? Would would the procedure be? So far, I've followed PF tek, just so you know.

Raising the Temperature improves incubation; they like to be plenty warm. Even with the tape off, some cakes just won't finish colonizing; eventually you may need to birth the cake--even if it's unfinished--into the growth chamber. This works if your cakes are at 90% colonization or better, but stalled. They will finish colonizing rapidly in the growth chamber. If any less that 90% colonized, go ahead and take the tape off and wait a week to see if the situation improves

I have a quiestion you know how people use the oven tek for sterility??

well I live at home and its hard to always do my work downstairs,,
so I was wondering I have a big heater in my room could I just turn that on full blast and work in front of that???? would that be just as good???
but of course my heater has a fan to blow the hot air out.. ,,,,but hey it might work thanx

Lichen (or anyone I guess)- the oldest of my jars are about three weeks now & not near complete (they've been growing but the temp here is usually in the 70's). I have the option of taking them to a friend's place where the temp is from the high 70's to the mid 80's, so would you advise that I just do that for now or should I transfer them to his place AND take off the tape? (or do something else entirely?) Thanks.
