G-Tools Insert Sieve for Ebb & Flow Tray

This insert sieve slots into the discharge point of G-Tools ebb and flow trays, filtering out plant debris every time the nutrient solution drains back to the reservoir. It suits any grower running a recirculating ebb and flow system who wants clean pipes and a healthy nutrient tank.

Ebb and flow systems flood and drain repeatedly throughout a grow cycle. Each drain cycle carries loose root material, growing medium particles, and leaf fragments toward your pipework. Without a sieve at the discharge point, that debris accumulates in pipes and tanks, creating blockages and harbouring bacteria.

This sieve fits the three most common G-Tools tray sizes: 1.1 x 1 m, 2 x 0.8 m, and 2 x 1 m. It sits directly inside the discharge fitting, so the full volume of returning nutrient solution passes through it on every flood cycle. Filtration happens passively - no extra components, no power required.

Setup takes seconds. Lift the sieve in, seat it at the outlet, and it is ready to work. Between cycles or at the end of a grow, remove it and rinse it clean. Pair this sieve with G-Tools ebb and flow trays and a reliable flood timer for a complete, low-fuss recirculating system.

For the best results, pair this with quality inline filters on your pump intake and replace nutrient solution regularly. Keeping the sieve clean after each cycle is the single easiest way to protect your entire recirculating setup from avoidable blockages.

Grower’s Note: Plant debris in recirculating systems breaks down quickly, lowering dissolved oxygen and encouraging pythium. Cleaning this sieve after every flood cycle - not just between grows - significantly reduces that risk. A quick rinse under the tap takes under a minute and keeps your nutrient solution far cleaner.
