Active Aqua 2.0 Ultra-Low Tray, 4' x 8'

Built to Beat the Edge Effect That Uneven Trays Create

On a standard flood tray, plants along the rim dry out faster than the ones in the middle — increased airflow along the edges pulls moisture out sooner, leaving you with an uneven canopy and a harvest that ripens in waves instead of together.

The Active Aqua 2.0 Ultra-Low Tray, engineered by Staal Plast, builds a fix directly into its channels: a gutter design that holds water slightly higher along the tray's edges, so when the flood drains, those edge plants stay irrigated a little longer than the ones in the center.

That's layered onto a 3-ply, UV-stabilized HIPS build in a low 2.5" wall designed specifically for single-tray mobile bench systems — gray, impact- and low-heat resistant, and made in the U.S.A.

Key Features & Benefits

• 4' x 8' x 2.5" footprint (W x L x H) — fits 4x8 rolling benches and racking systems built around that single-tray standard.
• Lifted-edge gutter design — raises the water level slightly along the tray's edges so rim plants stay irrigated as long as the ones in the center.
• 3-layer high-impact polystyrene construction — adds strength and durability beyond what a single-layer tray can offer.
• UV-stabilized top layer — protects the tray's gray finish from color change under grow-room lighting over time.
• 2.5" low-profile wall height — keeps the tray purpose-fit for single-tray mobile bench and racking systems.
• Impact- and low-heat-resistant, recyclable HIPS — stands up to daily handling and the conditions of a working grow room.

Who Should Use This Ultra-Low Tray

This tray suits growers running 4x8 rolling benches or single-tray racking systems on the ebb-and-flow method who want a more uniform crop edge-to-edge — anyone who's noticed rim plants finishing behind the rest of the canopy will get the clearest benefit from its gutter design.

Pairing It With Your Bench Setup

This tray is sized to drop directly onto a 4' x 8' single-tray mobile bench, such as Active Aqua's AARBK48 Rolling Bench System, or an equivalent racking system built to that footprint. If you're running an Active Aqua 2.0 Infinity Tray system instead, note that the optional AATINFLTR Drain Screen is matched to the Infinity Tray's AATIN4ETD/AATIN5ETD end sections rather than to this tray.

Frequently Asked Questions

What is the "rim effect" this tray is designed to fight?

It's the tendency for plants along a flood tray's edges to dry out faster than ones in the center, due to increased airflow at the rim — this tray's gutter design counters that by holding water slightly higher along the edges.

What is the tray made of?

It's built from 3 layers of high-impact polystyrene with a UV-stabilized top layer, in a gray, impact- and low-heat-resistant, recyclable finish.

What bench systems is it designed to fit?

It's sized for 4x8 single-tray mobile benches and racking systems, such as Active Aqua's AARBK48 Rolling Bench System.

How tall are the tray walls?

The wall height is a low-profile 2.5", matching the design standard for single-tray mobile bench systems.

Where is it manufactured?

It's manufactured in the U.S.A. by Staal Plast specifically for the Active Aqua 2.0 line.
