Plastic lid holes, 3/8 or 1/2 inch??
    #601518 -

When ordering the plastic lids for canning jars from Micron Magick, it says u can drill a 3/8 in. or 1/2 in. hole in the lid for air exchange. If one was planning to use a filter disk rather than polyfill, will it be anymore risk to drill a 1/2 in. hole rather than 3/8 in. hole?? Thanks!!!!!

watch out on these plastic lids
when you get them, you will notice that they dont have a seal around the top, like the regular mason jar lids do.
i used 5 of these with grain at two different spawn runs
all 10 of them got contaminated (with poly fill filter floss) while NONE of my metal seal lid w/ threaded ring got contam'd.

i've had about 1% contam rate with the metal lids and poly fill filter floss, i use about 1/4" holes. and i've had almost 100% contam with the plastics.

where you're using the filter disks (i see no reason to spend money on these myself.. personally.. when the poly fil works just as well) you might not have a problem, where the filter will be making a seal around the jar and the plastic lid

Keep this in mind anyway, this is my own experience.
i'm sure theres people here who have great luck with the plastic lids. but i threw every one of mine out

What I did is got a 1/2 drill bit and heated the end you put in the drill motor,with a propane torch.Then I put to the plastic lid for a filter.It doesn,t crack if you melt it

Well I haven't really had any problems w. contams in my jars. Even if they don't work and I get some contams, I'm willing to risk it to say goodbye to rusty lids. Anyone else use these w. good success?? thanks all!!!!

I've used all my lids about 20 times over.
if you lay them out on paper towel, they will dry... immagine that.
what do you do, throw them in a container and forget about em?
believe me, if you properly use your equipment, it will last longer.

Im just stating what ive found, that plastic lids & polyfill filter floss filters 100% leads to contams.
and its purely due to the fact that there is no rubber ring on them.

i as well have noticed less contams since i went back to using metal lids. i had maybe 30-60% contams with the plastic lids and now i have maybe 5% contams. but a lot has chnaged since then as well so i dont know if it was that only. although i *do* think that the seal is not as good on the plastic lids. it is not airtight. also rust is no big deal. it really doesnt matter. and yeah if you dry them off they dont get very rusty. metal lids! metal lids! much better! much better!

30-60% is much better than the poor poor luck i had. i had NEARLY 100%.. i threw out a few that werent even colonized just because the rest of the plastics were. but it was well over 80% i'll tell ya.

Yer right, the metal lids are about 5%.

uhm.. what are you using for filters?
i have a feeling if those micron filter or whatever from sporeworks (unnecessary) may make a better seal with the plastic lids.

I wonder what in the world the problem is!!?!? Anno uses plastic lids and doesn't seem to have any problems whatsoever. I mean, granted, he's way better at this hobby than many of us, but that's a small thing that should be easily fixable somehow. Well, I guess you guys have convinced me to stick w. metal. Thanks for saving me a lot of grief and heartache!!!!

I'm on my first run with plastic lids + polyfill in a 3/8th inch hole.. 10 jars of alien substrate with zero contamination 8 days in with quite good rhizomorphic growth. We'll see how it turns out.. Maybe I'll takes some pictures and do a mini-write-up...

anno has posted at least a few pics of his jars with metal lids. they werent canning jars though and therefore probably didnt have the rubber seal either...

if you have plastic lids and they are working for you then thats great but they didnt work for me. i dont know why and i said it could be to other factors as well since it was a while ago and with widemouth jars. now i use regular mouth jars (which are less prone to contams since the mouth is smaller). all the plastic lids i have are for the old jars and i didnt bother to get any more. but i alos think i am more sterile now.

if plastic lids work for you then thats good. metal lids are working for me so i dont see why i should use plastic. if you use plastic lids and are getting a high amount of contams then you might want to try out metal lids.

Anno is actually the reason i got the plastics. i just found they diudnt work, plus the jars came with metal's anyway. all i'm saying is keep your metal ones dry and they WILL NOT rust. i guarentee.

I had a whole batch of metal lids rust from just the incubation period. How am I supposed to keep those dry? Pop em off halfway through colonization and wipe em down with a wet, dirty, and moldy rag? Of course, the rust didn't hurt at all, but still...it happened.

after washing your lids-bake them in the oven to get rid of water-this will prevent rust :smile:
mine still rusted a little-i have resorted to sandpaper to try and remove it until i can get some plastic lids,or some new metal ones-

I use a small wire bush to get the rust off the lids.

The normal plastic BAll brand "storage" type lid was not designed to seal the jar air or water tight. The metal canning jar lids were.

Consiquently, the plastic lids leak or will "wick" minute amounts of air & water. To resolve that, simply take a few wraps around the jar threads w/teflon pipe thread tape. You can find that at any harware or building supply store.

Or, use a filter disc underneath them, which does - at least when I did it, resolved the problem.

Better yet, use bags w/sealer & filter. They are great.

dude, whats the damn humidity in your incubator.. 95%?

Rust doesn't hurt anything, but if it bothers you, it's easy
enough to paint them.
And there's no need to monitor the humidity in an incubator.
The substrate is 95%+ but that's inside the jars, not inside
the incubator. Moisture inside of a nice warm incubator is just
an open invitation to to contams.
Hope that helps.
