How long will poured agar last?

I was wondering how long poured agar will stay viable? Assuming everything was sterile and the procedure went as planned. I pour almost step fo step the same way RR does in his dvd's. Same flow hood, same petri's, same agar mix etc. So let's just say how long will agar's petri's stay viable? I'm wondering because it would be a lot more convenient to pour a 100 or so over a few days and be able to use them for a couple weeks rather than have to prep 25 petri's every time I need them.
P.S. I wrap my petri's in parafilm as well.

Well, some master cultures on agar are kept for months in the fridge.

If you're slipping them back into the sleeve and sealing it up, you can leave them for a month or two at room temperature. Beyond that time, they'll be too dry to use. RR

So would it be better to put them in the fridge while they're not in use, or leave them at room temperature?

Either one. I keep mine at room temp. Expect to lose a few to penicillium in storage, even if slipped back into the sleeve. Temperature changes cause air to breath in and out of the sleeve, and mold spores float along. RR
