Heheh - you're gonna 'dig' this - my clay recipe uses cat litter. It has to be the special kind without additives, but you can find it at Petsmart - Dr. Elsey's Precious Cat Ultra Scoopable Litter. It's pure clay, no perfumes or deodorants. A little goes a loooong way, and you want to mix it up really well. My husband suggested using a paint stirring bit on a drill in a 5 gallon bucket. I'm too lazy - I put a little bit in a big ziplock back and mash it up with water while I watch tv. Do whatever works for you. Hmmm, I didn't even consider using a Oster and let it mix on its own - it just might work.
I've mixed up a few batches so far and for me, it's just trying to add enuf water. I keep making it too thick. Once it's thin enough, maybe the consistency of pancake batter, I add some peat moss, and/or green moss, some kind of organic stuff to thicken it back up a bit. You can get very creative at this point -
When you start your project, it's important to not let the clay dry too fast. I, personally, use a piece of eggcrate for support. I mash in the clay rather thickly, then press in my cork pieces. I do this inside the tank while its laying on its back. After that, I add some climbing plants like spike moss, then cover the tank to keep the humidity in and put a light over it. I mist it periodically to keep the clay from drying so quickly that it cracks. So far, it's working out nicely. You can use red art clay if you want, but I don't have access to a store that carries it. Besides, I like to do things 'outside' the box, so to speak. And I like the idea that it's a no brainer to get the plants to grow up the wall.
Now, this 20g is my first clay project, and I like what I see. It will be the test of time to see if it holds up. So far, so good....![]()
