I put one in my new viv. It's not done but it has been tested, and it works, somewhat
I bought a bunch of drip irrigator nozzles, especially the adjustable ones. I laid down the tubing then foamed over it. The only thing I really don't like is that it is somewhat loud inside the viv when it first comes on because almost all air is coming through, and it almost whitles through the tiny drippers. I think i'll leave it always on to reduce the start up noise. Other than that no complaints, Ill have to see after its planted and been up for a little though.
Maybe I am wrong, but this system should produce big drips, which are not able to circulate in the tank and water all the plants. Also will be too big for frogs.
I made a misting system from various components (garden pump (higher pressure), air conditioning components and sprinklers for greenhouses) and it works pretty well. Frogs are loving it and going out for a shower.
