Drip watering is a very popular and efficient irrigation system in the greenhouse as it is the perfect way to water many greenhouse subjects.
The water is placed exactly where it is required, in the correct quantity and with the simple addition of a watering timer the system can all be automated so it can be watered at the correct time of day and when you go on holiday. The humiidy is kept low so fungal diseases are reduced.
Feed can be added with our range of dilutors and feeders.
All our drip system can be used in the greenhouse and polytunnel.
Two main systems
1) Individual drippers for pots and container grown plants
2) Drip pipe for beds
1) Individual drippers.
For those with many different crops with different watering regimes our adjustable output drippers are
best.
For those with many plants the same the hanging garden water supply drippers would be ideal and these can be used from a water butt.
Drippers are often also used with capillary matting so many smaller pots can be watered by placing them on the mat inside a tray. 
We carry in stock all the parts for GARDENA and you only need buy what you require - no large packs. All spare parts are easily available and this German high quality system never sems to fail.

2) Drip pipe
These are very useful in beds in Greenhouses and especially Tunnels.
The beds are connected up via our 16 tube and the drip pipe is placed just in the beds spaced normally at a maximum of 50cm apart. A tap is often incorporated so that a bed can be switched off if it is fallow or that bed does not require so much water.
