Active Aqua 2.0 High Rise Tray - 4' x 8' White

Inner Dimension (ID) refers to the usable internal footprint of the tray — 96" × 48" for the 4' × 8' format — which is the space actually available for pots, plants, and root systems. Outer Dimension (OD) refers to the outermost tray lip edges at 102" × 54", which is the measurement you need for bench clearance and installation planning. Always use OD when calculating whether the tray will fit your bench, and ID when planning your pot layout and spacing.

The 7.5" sidewall height and the heavier crop loads this tray is designed to support require closer support beam spacing — 12" (300 mm) maximum — to prevent the tray floor from deflecting under load. Standard shallow trays with lighter load ratings can span wider support gaps safely; the High Rise tray's deeper profile and weight capacity require a denser support grid beneath it. Confirm your bench sub-support infrastructure meets the 12" spacing requirement before loading the tray.

The 7.5" sidewall height accommodates a wide range of pot formats including standard 1–5 gallon square and round containers, tall nursery pots, and most fabric pot sizes used in commercial production. The deep sidewalls provide lateral containment for taller containers that would sit proud of or tip in a standard 3–4" tray — making the High Rise format the right choice for mid-to-late vegetative and flowering-stage plants in larger vessels.

Yes — the 4' × 8' outer footprint is compatible with the Active Aqua 4 x 8 Rolling Bench System and most standard 4'-wide commercial rolling benches. Confirm bench rail width and support spacing before installation, particularly given the tighter 12" sub-support requirement of the High Rise tray compared to shallower tray formats.

Both. White reflects radiant heat from grow lights rather than absorbing it, helping keep the tray interior and root zone cooler under high-intensity lighting — the same principle that makes white pots perform better than dark ones in high-output grow environments. It also makes residue, algae growth, and debris more visible during cleaning, which simplifies sanitation inspection between cycles.

The Active Aqua 2.0 High Rise Tray is available in three sizes: 2' × 4', 4' × 4', and this 4' × 8' format. The smaller options are suited for operations that need the deep sidewall format in a more compact footprint — useful for propagation areas, single-bench configurations, or rooms where a full 4' × 8' tray would exceed available bench space.

The integrated drainage channels run the length of the tray floor and are designed for straightforward cleaning — flush with water to remove loose debris, often managed with an Active Aqua Fill/Drain Combo Kit for better flow, then apply a diluted hydrogen peroxide or enzymatic cleaner and scrub with a soft brush to remove salt deposits and biofilm. The channel geometry prevents residue from pooling in corners, and the HIPS surface is smooth enough that most buildup releases cleanly with minimal scrubbing.
