Hi All,

A little while ago I went on holidays to find that my garden had
scorched in the heat in my absence. The watering system had worked as
programmed, but this was not nearly enough for the unexpected heatwave
... In short, this has lead me on a bit of a campaign to find a more
appropriate way of using just the right amount of water at just the
right time.

So far the best way of doing this seems to be to take
evapotranspiration into account - I can get weather data easily enough
from the local airport, and I can set my PC up to control the watering
system .. I'd probably have to determine the co-efficients for my lawn
/ garden beds through some trial and error.. The real question I've got
is - has anyone had any experience with this type of thing?

Comments welcome!

Cheers,

Matt
