Drip Feed Systems

When plants are grown using the drip irrigation method, a reservoir of nutrient is pumped via drippers to plants usually supported in pots, rockwool cubes or rockwool slabs. The excess nutrient can then be re-circulated or drain away, which is also known as ‘run-to-waste’. Alternatively, drip irrigation can feed plants, which are placed into individual pots that are filled with either coco coir or clay pebbles.

This method is also sometimes known as ‘slab culture’. It is a popular form of commercial hydroponics in countries, such as Holland. This type of growing technique is used for longer-term crops such as tomatoes, cucumbers and peppers where a larger root system develops. An advantage of this method is that only intermittent feeding is required and the media generally holds a large amount of nutrient as well. This is also good in the case of pump or electricity failure, as it can act as a buffer.
