Moss Wall Hangings?
There are patches of that verdant velvet known as moss all around my neighborhood and I'd like to propagate some of it indoors. I was wondering if I could make some kind of wall hanging on which to grow moss. Here are some of the ideas I've brainstormed without a lot of details because I haven't got them. That's what I need you for. Please respond with your suggestions.
1. Cover a frame (I have one that I took a canvas off of) with pond liner (or waterproof roofing paper if I don't have to buy a lot of it), laying channels of organic peat or coir fiber (coconut peat) on top of it and laying a mixture of cheap driveway sealant and the same peat on top of that (with just enough sealant to hold it together, with one end of the channels exposed for watering.
2. Some kind of hypertufa wall hanging that is waterproof on the back with hollow channels inside for watering. I'm not too keen on this idea as making hypertufa seems like a long and difficult process, what with all the drying and curing. Also cement isn't very environmentally-friendly.
3. Some rocks, peat, coir, mulch or some combination thereof sandwiched between a layer of wire mesh and some kind of hard waterproof (or waterproofed) backing. I could start this out horizontally if need be so the moss would help to hold it in.
