Last thursday I got my heating and thermostat delivered and today I got the tubs (30 3/4 x 22 x 7).

With a bit of luck I am getting the wood tomorrow, the shelfs will be made from melamine but I am not sure what to do with the sides, use some 2x4's or should I make the sides closed?

Are the snakes gonna experience more stress if the sides are open? or should that be no problem?

the other racks I have are completely closed at the sides but they weigh a lot and it would cost a lot more money as to using some 2x4's for the sides.

( ps 2x4 are just wooden poles right? I libe in the Netherlands europe and we use different names for those things haha)

thanks, Andrew
