Square Pot Saucer

Keep your grow room floor dry, safe, and organised with heavy-duty Square Pot Saucers. When watering soil, coco coir, or living substrates, collecting excess run-off (10 - 20% volume) is essential to flush out residual mineral salts and accurately test nutrient solution pH and electrical conductivity (EC). These durable saucers sit directly beneath square plant pots to capture excess run-off water, preventing spills, floor staining, and root-zone mess in indoor grow tents and greenhouse benches.

Unlike traditional round saucers that leave wasted dead space between containers, the square profile maximises usable floor area—allowing growers to pack pots tightly together under grow light canopies. Moulded from rigid, high-density plastic, each saucer features tall, raised edges designed to hold high volumes of liquid without bending or sagging when moved.

Easy to clean and fully reusable across multiple harvest cycles, these saucers fit standard square pots from 3.5-litre nursery sizes up to 18-litre flowering containers. They can be emptied manually using a siphon/syringe or left for passive bottom-wicking, making them an indispensable, low-cost accessory for soil, coco, and hydroponic setups alike.

Key Benefits:

• Run-Off Containment: Captures excess water and nutrient drainage to keep grow tent floors and greenhouse trays completely dry and clean.

• Space-Saving Square Design: Fits flush alongside adjacent pots, eliminating the wasted footprint common with round saucers.

• Rigid, Heavy-Duty Plastic: Built from thick, durable plastic that resists warping, cracking, and chemical degradation from fertilisers.

• Easy Run-Off Testing: Makes collecting drainage liquid simple for accurate testing of root-zone pH and EC levels.

• Reusable & Easy to Clean: Smooth plastic surface wipes down quickly between crop cycles for long-term use.

• Precise Pot Sizing: Available in five tailored sizes engineered to match standard square pot volumes from 3.5L to 18L.
