1x4 Flood Tables & Grow Trays
The 1x4 ft grow tray (12x48 inches) is the most compact elongated flood table format -- providing 4 sq ft of growing surface in a narrow single-row configuration suitable for windowsill-style setups, propagation benches where long narrow trays maximize bench use efficiency, and tight spaces where even a 2x4 ft tray is too wide. At 4 sq ft, the 1x4 tray is not a production table but rather a utility tray for propagation, seed starting, microgreens, small plant collections, and catch-tray applications under a single row of containers on a narrow shelf or bench.
Common Applications
The 1x4 ft tray sees its most practical use as a propagation bench component -- holding a single row of seedling tray inserts or a row of individual containers under a T5 fluorescent propagation light on a multi-tier rack. For ebb and flow applications at this scale, the 1x4 holds approximately 2.25 gallons at 1-inch flood depth -- workable with a small 5-gallon reservoir and a 100-150 GPH submersible pump. As a drip runoff catch tray: positioned under a single row of 1-2 gallon containers on a propagation or vegetative shelf to collect drainage from hand or drip irrigation events, keeping the shelf dry and preventing nutrient solution from accumulating on the floor.

Sizing Context
The 1x4 tray is the smallest practical flood table format -- smaller than 1x4 ft becomes difficult to work with for most hydroponic applications. For growers who need more capacity: the 2x4 ft tray doubles the width and provides a full ebb and flow production surface for 4-8 plants. The 1x4 serves best as a propagation and utility tray rather than a primary production surface. Fast shipping.
1x4 Flood Tables FAQ
What is a 1x4 flood table used for?
A 1x4 ft flood table is most commonly used as a propagation tray (holding seedling inserts or small containers under a propagation light on a rack), a utility catch tray under a single row of containers on a shelf or bench, or a small ebb and flow tray for compact setups. At 4 sq ft, it is too small for most production growing applications but useful for propagation, seedling staging, and any application where a long narrow tray format is practical.
How much nutrient solution does a 1x4 flood table hold?
A 1x4 ft tray at 1-inch flood depth holds approximately 2.25 gallons. A 5-gallon reservoir is adequate for this volume with comfortable working buffer. A small 100-150 GPH submersible pump fills the 2.25-gallon volume in under 2 minutes. Because of the small flood volume, EC and pH can shift more rapidly in 1x4 ebb and flow setups than in larger trays -- top off and monitor the reservoir more frequently than you would with a larger production system.
What plants can I grow in a 1x4 flood table?
The 1x4 ft footprint (4 sq ft, 12 inches wide) fits 2-4 plants in 1-gallon containers in a single row along the 4-foot length. For propagation: a full tray of seedling plug inserts or small propagation containers under a T5 bar. For microgreens: 2-3 standard 10x20 microgreen trays fit across the 12-inch width with some overlap. The 1-foot width limits container size to approximately 6 inches diameter without the containers extending beyond the tray edge.
Do 1x4 trays need a stand?
A stand is optional for 1x4 trays depending on the application. For propagation rack use, the tray sits directly on the rack shelf. For ebb and flow operation where gravity drainage back to a reservoir is needed, elevating the tray 4-6 inches provides adequate clearance for a small reservoir underneath or beside. The 1x4 tray is light enough when fully loaded that standard shelf supports handle the weight without a dedicated stand.
Is there a difference between a 1x4 flood table and a seedling flat?
Yes -- flood tables are solid-sided ABS plastic trays designed for hydroponic ebb and flow systems, with drain fitting ports and reinforced bases for container loads. Standard seedling flats (10x20 inch germination trays) are thinner, narrower, and designed for seed starting rather than hydroponic flooding. A 1x4 ft flood table can hold seedling flats on its surface as a propagation catch tray, but the two products serve different primary functions and are not interchangeable. The flood table is more durable, holds more volume, and has the structural and plumbing features for ebb and flow use that a seedling flat does not.
