Dimensions: 46.8in L x 61in W x 4.9in H. Tray sealant sold separately.

Who Should Use This

Frequently Asked Questions

How much length does each Middle Tray add to my run?

Each OG Middle Tray adds 5 feet to your tray run length. Add as many as needed to reach your desired total configuration.

What is the maximum run length achievable?

With enough Middle Trays, OG Tray systems can be configured up to 100ft6in in length. That range makes them suitable for large commercial greenhouse operations as well as compact starter setups.

Do I need sealant between Middle Tray sections?

Yes — Botanicare BOND THREE Lap Tray Sealant Adhesive is required for watertight seams between all OG Tray sections. It is sold separately.

When should I add a Middle Tray versus starting over with a longer Drain or End Tray?

Add a Middle Tray whenever you need to extend an existing run rather than replace it, since Drain and End Trays are fixed pieces that anchor each end of the system. Middle Trays are the only OG component designed purely to add length in the middle of a run.
