Just about any background in a humid environment will eventually grow moss/algae/plants. It just takes time. Cork bark mosaic is an easy background that plants like that always looks nice.
The cork panel background can be super thin, or tiles can be layered thicker and then carved down the same way that foam is carved down. But the appeal of cork tiles is that it is quick and easy to install plus it provides surface area without taking up valuable space like a thick foam background would. Just make sure you use the darker, thermally pressed tiles, not the lighter, glued tiles.
There have also been clay backgrounds, which are as easy to sculpt as one would expect. Plants and moss grow readily on clay backgrounds. Some people created clays with specific formulas and some people made it work with kitty litter. A word of caution though, too much sodium bentonite causes the clay to slide off of the glass once it has absorbed too much water.
thanks, I’ll stay from the hygrolon, kinda pricey anyhow.
There are some cheaper options if you wanted to play around with it.
I spent an afternoon looking on google for hygrolon or something like it for my viv. I found a couple places online but none of them seem to ship to Canada. I looked for hygrolon, epiweb, spyra, aquatmat, moisture retention mat etc but found nothing in Canada. Can someone in Canada let me know...
