Automatic Watering Systems

On Wednesday I managed to fit a watering system in my large greenhouse.

Drippers going to tomatoes 

 I've had two drip kits sat in the shed for years, in fact they moved with us from our last house. I brought them from a car boot sale for £5 a box and they come with all the fittings that I need, I just had to buy some clips to hold it in place.

£5 car boot buy

 I decided to fit the first kit in the greenhouse with all the tomatoes, hopefully this will save me lots of time in the summer and they'll be watered far more regularly reducing split tomatoes and blossom end rot. Another advantage is I will feel slightly less guilty about getting our neighbours to look after all my plants and livestock, as it'll be one less job to do when we go on holiday. 

Might need to reduce the pressure

The system waters all these plants and I'll have some trays on the large shelf  (to the left-hand side) to water my chillies as well

I now need to find a good quality electronic timer to control the watering system. I'd like to add other systems on to this for my other greenhouse and an area I'm going to make for propagation.

 Anyone have any recommendations on a good reliable timer that can manage multiple watering systems?
