HOW WORKS
This valve works like the original. Fill a tray up 2cm. Then a difference with the original, a new floater open a hole in the box and the air trapped inside can exit.
While the plants drinks the water, this floater goes lower, closing the box and trapping the water. Like when you put the finger on a straw and holds the water.
This feature allows total drainage of the tray, and then refill as the air enter by the bottom holes
