I've been trying (and failing) at figuring out how to get a decent greenhouse running. I can get a decent water supply silo built, but when it comes to doing any wiring and making sprinklers, I fail. I know have the tilled land set up so that water can run off into a special tubing under the ground to go back to the silo, but setting up sensors and using the silo to fill a sprinkler... i'm kinda fail at. Other things, is it possible to have the ground water supply water to the tilled land from below so i can make this a little easier? How might I solve this Irritating Indoor Irrigation Investigation.
