Tank Cover for Humidity
I ended up with an Exo Terra 18 cube that I have made into a vivarium, mostly using a kit from Josh's. It has the standard screen top on it, which is fine since there are only plants in it right now. Is there an easy DIY solution to covering the top? I will eventually get glass, but is there something that I can use to increase humidity in the vivarium while there are only plants in it that won't require much financial investment?
