I went out and bought some jars yesterday, but they may be the wrong kind. They are 1/2 pint Ball canning jars, tapered, but they are not wide mouth. They seem to be taller and skinnier than all the pictures I've seen. Will these do the trick? Everything I've read seems to indicate that the wide mouth jars are the best....I think they are shorter and more squat than the ones I bought but I don't know.

Skinny jars ok?

Thanks again,

a FOAF uses skinny jars (that's all he can get) and they work just fine. If you are fond of picking them up out of your terrarium and dancing around the room with them, take heed. The tall skinny 1/2 pint jars are a tad bit topheavy, compared to their more squat counterparts. Here is a picture of the cakes fruiting just fine.

Ok I just got back from the store, and these jars don't seem to be that bad, though I would still like to have the low form jars, I guess that i'm just Shit out of luck.

Aren't those full pints?
Or are those tall 1/2's?

By plinkerdink420 (Plinkerdink420) on Tuesday, November 13, 2001 - 12:27 am: usually has low form in stock, but they are a bit pricey... they also have spores, but those are pricey as well as they get them from an outside supplier

lid on box says half pint jars....

Thanks "Quo", I hadn't seen that.

By jared (Jared112) on Tuesday, November 13, 2001 - 01:27 am:

Ya, they look like pretty good jars, and they are not that tall either so I think that I will be happy with them. Even though I would prefer to have the low form jars, these actually are not that bad when you look at them close up.

I had to break down and buy the type of jars you had going, they are the taller half pints instead of the short squat ones. Well its been about 24 days now and they are 100% colonized except for the top *which normally is the bottom but I flipped them upside down* They apparently have stalled for the past few days. Right now I am cold shocking them in the fridge and than will return to their normal 85F temp. How long did it take for you jars to colonize, I am wondering since you used the same type as mine and I noticed you had mentioned yours took quite awhile aswell. Normally I am at 100% after 20 days.

cold shocking isn't going to help there.
you need a little air, usually to help finish stubborn bottoms.
remove any tape, loosen the lids, leave flipped.

Slow or Stuck Jars

By Dr. Cubesis III (Newbieshroomer) on Wednesday, December 12, 2001 - 06:10 pm:


I am using the same jars ( I think )
about two inches wide and four inches tall ( Approx ) Innoculated all of them on the 20th of last month, and last I checked ( about 4 days ago ) they were almost 3/4 colonized. And like you, the bottoms seem to be colonizing fine, but the tops are still a little sparse on colonization, wierd. I used two innoculation points on these jars.

I've discovered since I actually have shrooms growing, I myself barely check on the jars and decided awhile back to let each sit in the jar a month and a week.

I am planning on using the entire 12 jars to make some fairly large casings :) Probably 2 at 6 jars per. Very excited :)

I know this was directed to Jared, but I am sure he will show up soon :)

By Dr. Cubesis III (Newbieshroomer) on Wednesday, December 12, 2001 - 06:14 pm:


when you get back..

Is it really needed to flip the jars?

I mean, for the most part if the ratios are right,
if you leave a jar all by it's lonesome ( I don't use tape, don't need it ) for say, a month, or a little longer than that, shouldn't it just colonize itself? Without help?

Is flipping it just a way to colonize faster, or something truly needed?

So, if you are in no hurry to colonize quicker,
shouldn't you just leave them be till they are ready?

And, yes, I know what flipping them does... Co2 dispersal and all, but is it nessecery??

not usually 'necessary' per se, but can be very helpful in getting stubborn jars to finish.
i routinely flip all my jars once fully colonized anyway.

By plinkerdink420 (Plinkerdink420) on Thursday, December 13, 2001 - 05:02 am:

i flip mine after about 50% to 60% colonized and it makes them grow faster i think... i don't know about necessity as i have never not flipped them, but the way i see it is if i were them i would want as much CO2 drainage as possible and would love it if somebody flipped me...

By Snoopy (Snoopy) on Wednesday, December 19, 2001 - 02:54 am:

Hey to any experienced growers out there this is the first time that this has happened but. I am using the tall halfpint jars... *yah WHOOPS* and they are not 100% colonized and I already have some pretty fat shrooms growing invitro. ALl that isn't colonized is an area the size of a quarter on the top.* I flipped the jars quite sometime ago* And it seems as tho colonization has stopped. I don't want to grow these mushrooms invitro *personal preference* So I am wondering is it safe to birth them and basically cut the top off the cakes? I am sure the middle is colonized about 1/2" down from the top.. as they were innoculated on NOV 19th... What should I do I just don't want my cakes to contam on me if I birth them and leave that area exposed.

By Brad (Raze) on Wednesday, December 19, 2001 - 03:29 am:

Well, I wouldnt do that, that'd make your overall yeild less I'd think (less food and such)
And afterall, you can always birth when ready, and have a few bonus shrooms there. They look the same when you dry them. Its not like you're stuck doing it for th enext few flushes.

By An guy (Boomer) on Wednesday, December 19, 2001 - 03:40 am:

maybe you could try it in a box, load up some peroxide in that area, and then cover over with verm, or cut it out and cover with verm.

I had a little tiny area on top where the patches met up, they were just not closing up in the center, not nearly as big as a quarter though, but the cake was throwing pins...

I borned it, and did the h2o2/wet verm thing and it worked. that doesn't make a scientific study, I know, just saying....

Or cauterize the area- I found out that won't hurt- fungus'll grow over it eventually, but cauterizing give it time and makes it pretty unfreindly for aliens. Like maybe a 1st degree, just an immune coating, like...then cover with verm

Don't whup my ass if you try it and it don't work...:)

By Snoopy (Snoopy) on Wednesday, December 19, 2001 - 03:40 am:

Well I am not so worried about the loss of food... These are the tall halfpint jars so if I cut 1/2" off they really wouldn't loose much mass. It just appears they have stalled, and I don't see much hope for them growing further its been almost 30 days now..

someone just tell me to be patient =)

By onediadem (Onediadem) on Wednesday, December 19, 2001 - 12:32 pm:

Im in the same boat you are. I did mine on the 18th of nov, and flipped em about 10 days ago or so i guess. Looks like Pints are way slow. It was the only size jars I could find. So, I think Im gonna cut some off like you said, and leave the other half to see what develops.
good luck, i will let ya know how it turns out.

By Brad (Raze) on Wednesday, December 19, 2001 - 01:49 pm:

I use the tall jars too. I started mine on the 17th and 20th of november. Half are done, half are just behind
What temsp you at?

By Snoopy (Snoopy) on Wednesday, December 19, 2001 - 04:40 pm:

Well for the first 15 days they were at like 75ish regular room temp. And then with the slow growth I decided to build an incubator for them with a heating blanket and they are at a constant 83-87 degrees now.... still no growth progress. I may cut the tops off soon, and use a new terrarium with new perlite etc.. to keep the possibility of contams down.

By quote: (Quote) on Wednesday, December 19, 2001 - 04:43 pm:

take the lids off, then let the cake slide out of the jar just a little, and watch. they should finish in a couple days, if not then you could go ahead with surgury.

By Snoopy (Snoopy) on Wednesday, December 19, 2001 - 09:18 pm:

Quote: A little clarification let the cakes slide like 50% out of the jars so that there is more air space inside the jar? Or should I remove them completely from the jar?
On a second note I have had basically 0 problems with contams since i started about 4 months and I have successfully birthed and harvested probably 80 or so cakes, so I guess my apartment doesn't have much contams. Think they would be okay if I birthed them in a brand new tupperware container with new perlite?

" someone just tell me to be patient =) "

Be Patient!! Wait 7 more days!! LOL!

There ya go!

Does a pint jar cake take twice as long to colonize as a half-pint jar cake?

By Cragith Kilbonith (Kilborn) on Friday, December 21, 2001 - 09:54 pm:

No, about 4 or 5 days longer to colonize.

By MickyFinn (Mickyfinn) on Sunday, December 09, 2001 - 09:03 pm:

I am very new to this hobby and i was wondering, and i understand that full pt jars take longer to colonize. to insure full colonization, is it wise to make sure that the bottom part of the jar is inoculated a little more to insure that it colonizes? or should i just try to locate half pint jars and minimize the chance of not getting a full cake.

By Nan (Nanook) on Sunday, December 09, 2001 - 09:09 pm:

Put a couple of tablespoons of verm or perlite in the bottom of pint jars and use more inoculum.

Here's a tip tek that's great for pints.

Here's more discussion on skinny jars w/pics. They do take longer.

By exile (Exile) on Sunday, January 27, 2002 - 12:06 am:

Hey - quick question.. I've been reading teks with half pint jars saying to inject 1/4th a cc per hole in the jar, therefore 1 cc per jar... I was wondering how much I should inject into each hole for a 1pint jar..

I'd assume 1/2 a cc per hole?

a little extra is a good idea in pints, your figure sounds good.

By jim brown (Shrhobbyist) on Sunday, January 27, 2002 - 01:06 am:

Also, try to get the solution as far down the pint jar as you can. It will help colonization. If the spores all land near the top, the bottom takes seemingly forever to colonize.

By ion ewe (Ion) on Sunday, January 27, 2002 - 08:02 am:

A thin layer of perlite or verm at the bottom of the jar can help minmize that problem. Also, you should try to tilt the jar at a 45 deg. angle (toward the hole you're injecting at) and slowly rolling the jar to spread the spores down and across the surface of the substrate. Pints are pretty big, so you want to hit 'em pretty hard with spores.
You may want to try a liquid tek and inoc. with live mycelia when using pints.
