Not sure about self-watering system for succulents. IMO, they supply too much water to succulents (keep medium constantly wet). Personally, I would not use self-watering system for my plants.

How warm is it where they are kept? What succulents do you have? Many will be ok without water for 2 mo, especially if in cool temps.

Btw, some of them looks like sempervivums (would like better photo); if so, they do best outdoors. Not if in very hot climate.

Thank you for your answer. The picture was just to show the type of the system I found, those are not my plants. I have burro's tail, zebra cactus, hens and chicks and crassula nudicaulis. They are all pretty small. The temperature will probably be around 22 degrees.

Why not post a pic of your plants? Depending on what you have it's possible they'll be fine w/out any water for 2 months (as Rina said above), depends on what they are & how you're growing them.

I believe the system above will rot your succulents, it's too much water & the pic rather obscures what's in those glass receptacles other than rocks at their bottom. It almost looks like some kind of moss which is generally bad for succulents & combined w/ moisture almost guarantees rot. I'd stay away from this arrangement for sure.
