I am growing mushrooms indoors on coffee waste, and I am trying to find a DIY system to water them automatically.
Basically, the reasons why it is different than watering plants are: - You don't know where the mushrooms are going to pop out on the substrate surface, so the whole area has to be (more or less) uniformly wet all the time. - They are very sensitive, especially in the early phase. If they are dry for a few hours, they'll stop growing and die.
It could be a system involving a small tank that I need to fill every other day or something like this. I am just looking for a way to avoid having to spray them twice daily or more like now.
So you have an idea of the size, I am currently using wooden wine boxes. However, I might get/build something larger, so the new box can probably be adapted to the watering system if it needs to be.
My first idea was a kind of clothe that I would spread out on sticks over the mushrooms. I guess some clothe could be tight enough so that the water takes time to percolate through and drop on the mushrooms...
Any other ideas?
