Hey,
Yes, I made those Becca. I grow in a tank, so things have to stay small, and kind of "piece together", so the square/rectangle tiles work well.
Here's a good little challenge for those looking.... Name the plants!
I had at one time a bunch of these extra, but I've used most by now. If anyone is interested, I can make another batch. They'd be pretty cheap, and I need some more anyway.
