I assume you might be storing the plates in a chamber having at least 60% humidity at room temperature. And assuming your room temperature might be somewhere around 22-25°C, under such conditions you can store your plates for around 4-5 days. A maximum of 1 week.

If you can manage to store the plates in refrigerated conditions then you can easily store your plates for 15 days but not beyond that because the upper surface starts getting dry even when stored in 2-8°C.

My recommendation to you is to keep your plates in refrigerator for a max of 7 days, but if you have to store at room temperature please do not store your plates for more that 5 days.

Thank you for answering! I see that I should use my agar medium within a week.

I'll be more careful.

I would say you can store them longer. If you have plate with no special additive (antibiotics ) you can store them in refrigerator for around a month - IF you wrap them in plastic for sure so. Use the plastic in which the plates are originally packed and they will be fine. If you make your plate 22ml in thickness you will for sure not loose their humidity either. If you have additives they can be stored for twoo weeks tops.

hope this helps.
