The 1CELL ADD-ON MODULE is for those who wish to expand the 1CELL GARDEN - Complete or the 1CELL GARDEN - DELUXE systems.
Adding cells to the 1CELL GARDEN - Complete System requires a 250GPH Water Pump, a 4 Way Air Pump, and a Water Flow Distributor. If you are purchasing an AQUAPONIC URBAN GARDEN with the intention of later
expanding, we recommend that you purchase the ADD-ON READY 1CELL GARDEN - DELUXE which includes these items. If you already have the 1CELL GARDEN - Complete System and you would like to expand your system, you can purchase these items in the ADD-ON MODULE ACCESSORIES
section of the PRODUCTS page.
