I was just wondering about removing the tape during incubation to promote growth. Would that not allow contams in? My cakes are only colonized where the spore water entered the jars. It has been ten days and about 15% colonized. I read in the archives about removing the tape to allow air in but I am worried about allowing in contams. following the simple Pf tek, I am using Mex Cub spores and have the jars in a 85 degree bath that gets no light. Any pointers would be greatly appreciated.

If they are in a closed incubator, just put some iodine in the water, and leave it shut. Only open it to check on them or fill with water.
The verm barrier is just that... a barrier to contams. It works very well, albeit not so good if it is completely saturated with moisture (the top should stay fairly dry in comparison with the substrate).
If you are really concerned, just use a rubber band to put a filter cover over the lid after wiping with iso. Use a piece of a good "allergy-free" vaccuum cleaner bag. These filter down to around 3 microns and are the best thing you'll find outside lab supply and expensive Hepa.

I would suggest giving your jars more time. It has only been 10 days since innoculation. Usually you don't see any noticable germination until about day 5, so your mycelium hasn't been growing too long.

Because messing with the lid is a contamination risk, I'd wait at least 5 more days to see if the jars speed up. And if you go without looking at them at all it helps.

I appreciate the info. I was wondering how long to wait before I attempted to try something to promote growth. I never tried this strain before. The incubator I am using is just a aquarium with a sealed plexi glass top with a under-aquarium heater to maintain 85 degrees. I already have Iodine in the water to prevent any strange growth. I will be using the same aquarium when I birth the cakes, Thanks again

I have friends who have waited as long as a month before 100%. These things take time. Although a month is on the far end, it's a far cry from far fetched.

Hey Sparks...

Try some micropore plastic bandaid-type tape.

Stuff works great...

Errrr.... Well, prolly the Pf-founded verm barrier works great, and the tape just helps ya
feel that much more secure...

And dude, DON'T open the lids this early....
Why chance it? At least let the top colonize....

Well, i dont even use tape. Risky...most likely. Lost any jars....yes. But all I do is boil my jars with their foil covers. Then I have them in a small rubbermaid container that is filled about 3-4 inches with water, sitting on a heating pad. I leave the foil on the tops of the jars.....so no condensation falls from the lid into the jars, but the foil is just loosely resting on the lid, air can still come in to speed growth, 2 of my jars are 75% colonized....and its only been 7 days. The others are 50-60% done....not to bad of incubation time so far. I wouldnt recommend this unless you have your top layer of dry verm to act as a air contam barrier.=

Well it has been 18 days and I have seen no further growth. I will give another week but then I might try to add some air. I followed the tek exactly so I do not think I am low on moisture. Could the specific spore be causing the slow growth? I am probably just wanting nature to be a little quicker. Thanks

Did you get water in your jars during steaming?

What temp at you incubating at?

I am unemployed as of now, so watching jars colonize for ten days really feels like 2 months because I was so anxious for them to finish, and I am home most of the day so I am constantly checking. Much like staring at the clock in school and waiting for time to pass. But i just had my first successful harvest yesterday, and let me tell ya, the experience I had from the fruits of my labor was well worth the wait.

Good luck, dont give up.
