These are awesome!! Can't say enough good things about earthboxes, they really grow strong and vigorous plants. Follow the advice on the youtube and wait until the plants start growing after transplant to fill the reservoir. Only fill the reservoir when it's dry. Coots take n' bake can be a little heavy for use in an earthbox, I ran three cycles with it, but it does better with an extra bit of aeration and peat vs all the compost of coots. BuildASoil Light, 3.0, or Dominion really work super well in an earthbox, want to make your own soil, try the 3.0 kit.
Pro Tip: You can put an aquavalve from autopot in the bottom and run the tube out the drain hole.
Fully automate the EarthBox!
Happy growing!!
