 agar in 1/4 pint jars

I'm planning on doing agar in little mason jars rather then petri dishes. My question is, Can I put a 1/4 inch hole in the lid and stuff with polyfill for clean airflow? I am pretty sure I know the answer but just incase somebody knows something I don't please let me know.

Absolutely. Personally, I like these jars for agar work:
They're 1/2 pints, but they're also wide and really short. I drill two 1/4" holes and use postal tyvek as a filter for a clean look like so:
  
 
They're perfect for dropping pins in for cloning purposes:

Very nice FooMan. Easier than ordering petri plates.

I used to utilize baby food jars as well...with the lids on tightly(after autoclaving). I think such a small quantity of mycelium does fine without the need for additional air exchange (most species). My adult friend would eat the baby food for me (yech).
I incubated my petri dishes(or baby food jars) in ziploc bags for many years without any problems, and without reopening them until required. Now I provide them weekly air exchange(open bag and close) unless they are in long term cool(or other) storage. But you can typically get away without opening them until needed.

In my opinion petri plates are better, for storing a culture is necessay a vial or a test tube.
Using jar or little jars you use more medium and you work bad.
If you don't have the money for plastic petri plate buy 20 glass petri plate one time and they last a life.
Plastic petri however are better because with the years the glass one aren't so transparent as new.
Using jars, drops of water inside the jars can be a problem, and cause bacteria contaminations or slow the growth of the mycelium.
Bye,
Fabio

drops?
i have used jars for almost one year and never got problems with contams nor slow growing.
you use less agar than petri dishes because jars diameter is smaller.
also, jars lid is an excellent barrier against external contams; petri dishes stored for a long time become contaminated easily because both parts fit loose.
other problem with petri dishes is water condensation when the agar is hot

What he said.
I have had zero problems using jars. I also use pyrex petri dishes and find that of the two, petri dishes are far more likely to have condensation than jars. Another advantage to the jars is that you can inject a spore or culture solution into them without the need for a glove box or flow hood. Yet another advantage is that they can be sterilized with the agar inside of them without worrying about the agar boiling over and making a mess. That's much easier than having to pour hot agar into plates, which again requires a glove box or flow hood to minimize contam risks.
The pros for petri dishes (IMO) are that they are cheaper (plastic ones anyway), they take up less space, they are a bit easier to store and stack and you can see through the tops of them, which makes it easier to see what kind of growth you have.

There is a thread just for building up your post count. But why not add something useful to build it up!?!?!?

i want to try the method of the jars another time and see what happens with the condensation. However the petri are really more useful than jars, speaking about space and way to work.

I have strains stored in baby food jars and they work fantastic for that, but I wouldn't recommend doing any kind of isolation work or cleaning up of cultures in a jar. Petri's are more suitable for that kind of stuff. All you have to do is keep your dishes insulated to minimize condensation.

yeah idk why that even exists. if you have nothing to add. then dont.
using jars seems like a great idea, especially because i dont know where to buy petri dishes except mycosupply. i can just go down the street n get some jars.

I just those jars with great success. I put four nail holes in the lid and then use tyvek between the lid and the jar.
Just to chime in.

FooMan....check out a post I made a while ago, Dishes with no flow hood.
Condensation is not a problem either if you let it cool overnight.

Oh yeah, no way would you pour these after PCing the agar. They work just like grain jars. The condensation can be a problem though. Like he said, don't take them out of the PC before they are room temp. Seems to help.
