These tray are great. But the description was lacking details.

They do not fit standard 10x20 seed trays inside.
I was hoping to put four seed trays in each 2x4 flood table. Instead I used them to fit three 6" x 40" coir grow bags. The table is perfect for those.

Inside dimensions are 19" wide. 42.5" long. 3.5" deep to the first step. Overall depth is 6".

Outside dimensions are 24.25" wide. 48.25" long.

However. You could easily trim off 1" around all sides and atill get 6" depth of flood.
The next inside step could remove an additional 3/4" all around and you would only loose 1" of depth

Heavy duty plastic. Should last forever.

Super fast shipping.

I'd really stilll like to find trays that will fit four standard 10x20 seed trays.
