Collection: Run-off Trays
Shop Run-off Trays at A-Grade Hydroponics — drainage trays, recycled Garland trays and G-Pot bases and grids for every pot size and setup.
Testing your run-off is one of the most reliable ways to check how your plants are taking up nutrient — comparing feed EC and pH against what drains out tells you whether your feeding programme needs adjusting. The right tray also matters mechanically: air-pruning fabric pots need airflow underneath as much as drainage, which is why G-Pot bases use a tapered design rather than a flat catch tray.
What's in this Collection?
TBC EZ-PZ Run-off Trays — 15.5in for pots up to 7 Gallon (26.5L) and 22in for pots up to 15 Gallon (57L), each including 4 legs and a 13mm MPT drainage elbow fitting
Garland trays — square (60x60cm, 80x80cm, 100x100cm) and rectangular (100x45cm, 120x55cm), made in the UK from 100% recycled polypropylene
G-Pot Base drainage trays — 480mm for pots up to 38L (10 Gallon) and 550mm for pots up to 76L (20 Gallon), with a tapered airflow design and 150kg load capacity
G-Pot Grids — 400mm and 470mm risers that elevate pots above collected run-off to reduce root rot risk, pairing with G-Pot Bases and GeoPot fabric pots
Start with your pot type and size. Standard plastic or fabric pots suit the TBC EZ-PZ trays; air-pruning pots like GeoPots need a G-Pot Base instead, since the tapered design gives airflow underneath as well as drainage. For multiple pots or a whole bench, the Garland range covers 60x60cm up to 100x100cm square trays and 100x45cm to 120x55cm rectangular trays. Growers running a full bench of air-pruning pots can pair G-Pot Bases with G-Pot Grids for extra elevation, or interlock two G-Pot Bases together for a combined stand-and-tray setup.
A-Grade Hydroponics stocks run-off trays, drainage bases and pot grids to suit everything from a single fabric pot to a full bench. Chat to our Melbourne-based team about sizing, then browse the range below.

Run-off trays
Run-off trays capture excess nutrient solution draining from your grow pots, so you can test pH and EC and monitor plant health. This range spans compact TBC EZ-PZ trays for pots up to 15 Gallon, large-format Garland trays up to 100x100cm, and G-Pot bases and grids purpose-built for air-pruning fabric pots.
Why run-off testing matters
Testing your run-off is one of the most reliable ways to check how your plants are taking up nutrient — comparing feed EC and pH against what drains out tells you whether your feeding programme needs adjusting. The right tray also matters mechanically: air-pruning fabric pots need airflow underneath as much as drainage, which is why G-Pot bases use a tapered design rather than a flat catch tray.

How to choose
Start with your pot type and size. Standard plastic or fabric pots up to 15 Gallon suit the TBC EZ-PZ trays; air-pruning pots like GeoPots need a G-Pot Base instead, since its tapered design gives airflow underneath the pot as well as drainage. For multiple pots or large-format trays under a whole bench or grow tent, the Garland range covers 60x60cm through to 100x100cm square and 100x45cm to 120x55cm rectangular trays.
If you're just getting started with one or two pots, a single TBC EZ-PZ tray or G-Pot Base is enough to capture run-off for testing. Growers running a full bench of air-pruning pots can pair G-Pot Bases with G-Pot Grids (400mm or 470mm) for extra elevation, or interlock two G-Pot Bases together for a combined stand-and-tray setup.
