How Ebb and Flood Works

Plants sit on a table, placed above a nutrient solution tank. A timer is used to set the frequency at which nutrient solution is pumped from the tank to FLOOD the table and is then allowed to EBB away.

As the table floods, the plants take all the water and nutrients they need. All stale air is expelled from the root zone then, as the solution drains away, fresh oxygen is pulled back down directly to the roots.

The amount of nutrient solution used is easily measured and this allows experienced growers to tailor feeding schedules to get the optimum yields from their plants.

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

Ebb and Flood Hints and Tips

Golden Rule: Keeping a dedicated flood diary is the key to massive growth and yields. Note the number of floods compared to the amount of solution needed to top-up the system each day. The amount of solution used is directly related to rate of growth; maximise consumption and maximise growth.

By experimenting with the number and duration of floods, growers will find the optimum number of floods for their growing environment. The flood diary can then be used as a guide to take the guesswork out of growing and achieve bigger yields time after time.

•  

  If using clay pebbles treat the Ebb & Flood as a re-circulating hydroponic system and top up the tank every few days with half strength nutrient solution.

•  

  If using an absorbent medium, the aim is to minimise run off and top up the tank with full strength nutrient solution.

• When using pots in Ebb & Flood, space the pots as required and cut holes in the correx top plate for them to sit through, this will keep light out of the root zone. Cover the base of the planter with spreader mat to allow the roots to grow out of the pots and onto the mat.
