Hellos fellas. Recently I have printed a little float valve which works similar to an Autopot.

The valve maintain a 2 centimetres of water at the bottom of any tray.

I want to try to grow with , but I don't know what medium is the best to do it.

I have here:
200 L of perlite
40L of expanded clay balls
Coco
Peat

I want a lot of air for the roots and enough moisture to don't complain about hand watering anymore.

Any recommendation is welcome
