Botanicare White 44 in x 24 in x 7 in Grow Tray

The Botanicare White 44 x 24 inch Grow Tray is well built of heavy gauge plastic and has a deep drainage grid that won't easily clog.

I bought a couple of cheap plastic sawhorses and a 2 x 4 ft sheet of plywood to support the tray, and have a 5 gallon pail underneath with an Eco66 pump for watering. A Titan Apollo 7 timer runs the pump for 4 minutes and floods the tray about 1 inch deep. After the timer turns off, the water drains down thru the single fitting and hose back into the pail.

The largest drain area is recessed about 1/2 inch deeper than the rest of the tray, so if you want to completely support the tray on a sheet of plywood, you will have to cut a small rectangular hole so that this drain area doesn't elevate the rest of the tray. But, you'd have to do this anyway if you are adding any fittings to the drain area.
