Is Run Off Trays 15" & 22" Hydroponic Drain Trays suitable for beginners?

Run Off Trays 15" & 22" Hydroponic Drain Trays is designed for straightforward assembly and operation. Most hydroponic systems require basic understanding of nutrient mixing, pH management, and water change frequency. As a beginner, the most important habits to develop are daily monitoring of pH and EC, regular reservoir top-ups with pH-adjusted water, and weekly or fortnightly full nutrient solution changes. Run Off Trays 15" & 22" Hydroponic Drain Trays comes with setup instructions to get you started.

How often should I change the nutrient solution in Run Off Trays 15" & 22" Hydroponic Drain Trays?

For most recirculating systems, perform a full reservoir change every 7–14 days during active growth. In smaller systems or with heavy nutrient demand, changes may be needed more frequently. Between changes, top up with pH-adjusted plain water as the reservoir level drops — plants drink water faster than nutrients so EC naturally rises over time.

What nutrients are compatible with Run Off Trays 15" & 22" Hydroponic Drain Trays?

Run Off Trays 15" & 22" Hydroponic Drain Trays is compatible with all liquid hydroponic nutrients. Terra Aquatica (formerly General Hydroponics) TriPart, NovaMax, and DualPart ranges are excellent choices for beginners and experienced growers alike. For coco-based systems, use a coco-specific A+B nutrient formula. Always follow the manufacturer's mixing instructions and check pH and EC after mixing.

Hydroponic Run Off Trays: Efficient Drainage for Run-to-Waste Systems

Run off trays provide a simple and effective solution for managing nutrient drainage in hydroponic and soil-based grow systems. Designed for run-to-waste setups, these trays enable controlled collection and removal of excess nutrient solution while maintaining a clean and stable growing environment.

Available in 15" and 22" sizes, these trays are optimised for use with fabric pots and standard plant containers. Each tray is fitted with a precision-moulded 19 mm drainage outlet and elbow, directing run off efficiently to a single drain point or central collection system.

The integrated drainage point also functions as a monitoring location for pH and EC readings, allowing growers to assess nutrient uptake and optimise feeding strategies in real time.

The rigid construction prevents bowing under load, ensuring consistent drainage performance even in high-volume watering systems.

Frequently Asked Questions

What size run off tray do I need for my pots?

The 15" tray suits pots up to 30L, and the 22" tray suits pots up to 90L. If you're running a mix of pot sizes or planning to scale up, sizing to your largest pot gives you room to grow into the same tray rather than needing to upgrade later.

Can I connect multiple run off trays together?

Yes. The optional PVC Tee Piece lets you link several trays into a single central drainage point, useful for multi-pot setups where you want all runoff directed to one collection or monitoring location rather than managing each tray separately.

Do I need the extension legs, or is the tray usable flat?

The tray works flat on the floor, but the extension legs elevate it to improve gravity drainage, particularly useful if your collection point or drain line sits below floor level. Worth adding if drainage seems slow or pools rather than flowing freely to the outlet.

Can I use this tray with a recirculating hydroponic system?

These trays are purpose-built for run-to-waste setups, where excess solution drains away rather than being collected and reused. They're not designed to integrate with a recirculating system's return line, if you're running recirculating, you'd need a sump or catchment tank instead.
