This is a sustainable unit. I have grown lettuce, basil, oregano, parsley, chard, flowers, tomatoes etc. I moved and it is no longer needed. Works great for herb nuts like me! I bought it with the microgreens sprouter and the 20 gallon holding tank. This also comes with minerals, Ph testing kit, water pump, waterproof mat, microgreen extension kit, instruction manual and Day/Night timer for the lights. Paid over $1000 new 435-704-1314 Lily Absolutely NO Zelle or Venmo. Please view my other listings.
