The Ebb & Flood produces much bigger harvests than plants grown in traditional pots, but is as simple to use and is more versatile.

The timer triggers the pump to ‘flood’ the bottom of the growing medium and gravity pulls excess solution back into the tank along with fresh air, ensuring the medium is regularly flushed with nutrients and air resulting in a highly oxygenated root zone and huge yields.

The FLOOD - A timer controls how often nutrient solution is pumped up from the tank to FLOOD the growing medium. During floods, the plants take the water and nutrients they need and stale air is pushed out of the root zone.

The EBB Once the growing medium is flooded to two thirds the solution drains (EBBs) back into the tank, pulling fresh oxygen down directly to the roots.

Bigger Yields the 'little and often' feeding schedule, combined with the highly oxygenated root zone, means a healthier plant and larger yields.

Match feed frequency to the needs of the plant - Provide the perfect conditions for a plant throughout its lifecycle by altering the frequency and duration of feeds. So that nutrient uptake is optimized and yields are maximized.

Versatile Either grow in individual pots in clay, coco, Rockwool or soil, so you can move plants around under lights as and when required, or fill the planter with clay pebbles – so that it becomes a large pot perfect for specimen plants.

Space efficient– The 1.2m2 Ebb & Flood is just 22cms tall to maximize headroom. 

Reliable– Built to last for decades with high-performance fittings and top quality pumps have unrivaled reliability.

Nutriculture holds the record for the world’s longest tomato plant. It was grown in an Ebb & Flood system.


Ebb & Flood produces huge yields because of the large amount of oxygen it provides around the roots. In a standard pot, the media around the roots becomes saturated, reducing the oxygen content if you can provide the roots with more oxygen the plants can take up more nutrients and water and will produce bigger yields. 

Ebb & Flood provides the roots with fresh oxygen-rich air every feed. The stale air is pushed out each time the water rises into the 'Flood' table and when the water drains back into the tank fresh air is pulled into the root area.

The water left around the roots between the flood periods is highly oxygenated. Most rootzone diseases can't survive in an oxygen-rich environment, so you get healthy disease-free roots and highly productive plants.

Respond to the needs of the plant - It is very easy to monitor the amount of nutrient solution used and this allows experienced growers to tailor feeding schedules to get the optimum yields from their plants.
