Each Ebb and Grow 6 pot add-on kit includes all of the tubing and fittings needed. You do need one 50 liter bag of grow rocks for each 6 pot add-on.

Controller units are available separately if you wish to make your own system and they include the pumps. Hydroton is not included with the systems. Each 12 Grow Pot System will require 2 bags of hydroton.

NOTE: As with most ebb and flow systems, the Ebb & Grow controller and 2-gallon pots must be on the same level to operate properly.

Ebb & Grow Multi-Pot System includes:

• 6 2-gallon pots

• Tubing and connectors

• Detailed set up and operating instructions
