Hello. I went to home depot and picked up some supplies for a new exo build I am about to start. Got pvc and eggcrate and silicone (lots of it)zip ties and a few other things. I also picked up some mosquito mesh that I thought I could use to close in the falsebottoom and act as a substrate separator. I just noticed it is made of fiberglass. Will this be okay to use?

I use fiberglass window screen as a barrier in my vivs and have had no issues. It won't break down, so I don't see any problems with it.

Best

i use it as well, no issues here

I agree. I use the same mesh in all my vivs for the past 5 years and never have a problem. I used to order the substrate divider offered by Black Jungle until I realized that it was the same thing I could get a whole lot cheaper at Lowe's or Home Depot.

Yeah I just realized that. I basically now have a life time supply of substrate divider because I could only find it in bulk and bought about 15 feet of the stuff.
