I was inspired by Av's thread about his heli set up, particularly the self watering system. So this weekend I started thinking about how to incorporate it into a glass terrarium. So this is a spare 10g aquarium I had laying around.
I was a little worried about cutting holes in the glass for the tubing, but it turned out to be pretty easy. Dremmel makes a bit for that. So I cut 3 holes. One for the input from the pump, two for drainage. I hadn't planned from the beginning to have two drainage holes, but I had to reassess after a little poor planning. And it worked out for the best anyway.
Here's a couple of really bad pics...
The input line is the same size as both drain tubes together, so it was pretty easy using the flow control to find a nice equilibrium. The way it's set up now, it will keep the tank flooded to a 2" depth (give or take a little) indefinitely.
At this point, this tank is practice for a larger project I'm hoping to do in the future. But I'd like to be able to use it for smaller heli's or even for germination purposes if I can get the design nailed down.
So the next step is to figure out how best to keep the humidity high. I'm open to any ideas here. At this point, I'm planning to use a combination of plastic egg-crate and LFS with a small fan. This has proven to work for me based on the terrariums I have now, so there must be a way to adapt it.
Thanks for looking! As always, I'm open to any questions/concerns/feedback.
