About Ebb/ flow systems
Ebb/flow systems are the most frequent used cultivating system for plant production in a modern greenhouse. In Europe, who is the pioneer continent in this branch of business, the ebb/flow system is widely used. Other continents, where a lot less- or no environmental requirements exist, the systems are used considerable less. But the spreading in these areas is moving rapidly as the environmental demands get more strict, and also at a time that more modern technology is introduced, which makes optimal use of the ebb/flow systems.
An ebb/flow system is a closed system, where the often fertilize dispensing watering is pumped out on the trays, by which the cultivation starts soaking up the water and the added fertilizer. After a certain time the trays are emptied again, and the remaining water runs back into a central tank. It can then as needed be added more clean water and fertilizer till the mixture again has the desired composition before the next watering is done. See the example of a typical installation with ebb/flow tables, see above.
Ebb/flow systems holds a number of advantage, i.e.:
- No water or fertilizer is wasted.
- Under watering principle.
- Possibility of a possible automatic composition of the fertilizer in the water.
- Possibility of a very precise management of watering times.
