I am selling two excellent condition 3′ × 3′ heavy duty grow trays (black color) from American Hydroponics (amhydro dot com) for $30 each. (They retail for $75 – $100 each so you save $90 – $140.)
Description from the AmHydro website:
The American Hydroponics 3′ × 3′ grow tray – one of the originals! A 3′ × 3′ growing area is perfect for growing healthy plants. It is easy to work with and a great size for light displacement. With the fill and drain in the middle of the tray, you will not have standing water after the tray has drained. These trays are 4" deep and are .156" thick.
I will deliver free if you are within two miles and you buy both trays.
