Active Aqua Low Rise 4x4 Flood Table, Black | 28 gal, 3 3/4 in Sidewall

How the Active Aqua Low Rise 4x4 Flood Table Is Built

The AALR44B is a low rise flood table from Active Aqua, sized at a nominal 4 by 4 ft. Outside it measures 47 3/4 by 47 3/4 in with a 3 3/4 in sidewall. The growing area inside is 46 1/4 by 46 1/4 in, and the inside depth is 3 1/8 in. Filled to the brim it holds 28 gallons. The floor carries a grid of vertical channels that slope toward the center of the table. Those channels feed into horizontal channels that carry water to the drain, so the surface clears quickly between irrigations. Curved, narrow edges let several tables sit closer together on a bench or rack. The table comes in black only, which keeps light off any standing water. The boxed table ships at about 12 lb. The UPC for this model is 638104014816.

Setting Up a 4x4 Flood Tray for Top Feeding

A 4x4 flood tray earns its space under top-fed containers, where every irrigation sends runoff somewhere. Set it on a stand or bench that supports the whole floor, not just the corners. Pitch the table very slightly toward the drain end so the channels empty fully. A level table holds puddles, and puddles grow algae and fungus gnats. Space pots on the grid so roots never sit in the drain path. Run the drain line to a waste tank or back to a reservoir, depending on whether the system recirculates. Recirculated runoff needs its EC and pH checked before it goes back to the plants. Scrub the channels between crops with a soft brush and a mild cleaner, then rinse well. Wipe the rim dry after cleaning so salts do not build up along the edge. The shallow inside depth suits runoff collection and short flood cycles better than deep flooding. Check that the bench height leaves room under the table for the drain fitting and hose.
