Flood Trays + Reservoirs
Greenhouse flood trays and reservoirs hold feed where roots can reach it and return the runoff, so every plant on the bench is watered alike. Tents run an OD tray and benches take ID or Low Tide trays on a stand. Larger rooms add rolling benches and bigger reservoirs.

Flood Trays + Reservoirs
Greenhouse Flood Trays, Reservoirs and Benches
Greenhouse flood trays hold plants in a shallow, sealed basin that floods with feed and drains back to the tank. This collection gathers the whole setup: Botanicare and Active Aqua trays, Botanicare and collapsible reservoirs, and the stands and rolling benches that carry them....
For trays only, see flood tables and trays. Tanks have their own hydroponic reservoirs page, and both sit under containers and support.
Types of Trays, Reservoirs and Benches
Flood Trays
Botanicare OD trays are sized from the outside, so the 4 x 4 drops into a 4 x 4 tent. ID trays give a true inside floor, 48 x 48 inches on the 4 x 4, with 7 inch sidewalls. Low Tide trays run a 3.5 inch wall, and Active Aqua Low Rise tables suit benches.
Reservoirs and Lids
Botanicare reservoirs come in 40, 70 and 115 gallons with bulkhead ports for an external pump. AutoPot FlexiTank and Grow1 collapsible tanks fold flat and fit through a standard door.
Stands and Rolling Benches
Fast Fit stands go together without tools and carry a 4 x 8 tray at 25 inches. Botanicare Slide Bench Trilock carries 25 lb per square foot, and the Active Aqua rolling bench frame rates 18.
How Growers Set Up Flood Trays
Support a tray along its whole length, not just the corners. Pitch it slightly toward the drain, and set the overflow so pots flood to about a third of their depth. Site full reservoirs before filling, since a 70 gallon Botanicare weighs close to 600 lbs full.
Frequently Asked Questions
What is a flood table used for?
A flood table holds potted plants or media in a shallow tray that fills with feed, then drains. The Botanicare OD 4 x 4 has 6 inch sidewalls, enough for pots to sit in 2 to 3 inches of solution. Its diagonal drainage grid pushes water toward the fitting.
What is a flood and drain system?
A pump fills the tray from a reservoir on a timer, then the solution drains back by gravity. Botanicare's Slide Bench adjusts up to 5 inches of pitch, which gets water off a long run without pumping. Low-profile trays like the Low Tide limit how much can spill.
What size water reservoir do I need?
Size for how often you want to mix, since Botanicare notes mixing frequency pushes growers up a size. Check the floor too. A 70 gallon tank puts close to 600 lbs down, and AutoPot's 105 gallon FlexiTank carries about 876 lbs of water.
