Yes, for now I spray it two times a day. The moss ball dries up so quickly, of course even more so as it sits freely in the air.
So not practical at all, but very nice to look at
Maybe mossball formed around some type of reservoir core with a low permiability? More watering than normal I’m sure but maybe more of a every 2 days scenario.
Also great idea. My idea right now is an infrared thermometer to measure when the surface is dry and then sprinkle it with water when it’s necessary… but that’s a bit overengineered :P
What if you a sprayed layer of something onto the mossball to slow water exchange? Not sure what, something like starch or collagen occurred to me but that probably only works if they can dry.
