Then whilst you're on holiday a strict hosepipe ban is imposed and you end
up with a fine which could be in the regioin of hundreds of pounds!

And the likely hood of that is...... could always have it rigged up to a
Butt tank etc.

I've used drip systems with timer, a la Hozelock and Gardena, i've also
used the Tropf Blumat system as well. I'd go for the Tropf Blumat
system. no need for timers, or adjusting drippers, wasting water because
of excess water, pots not needing it etc. Main disadvantage is the
greater expense of each unit needed for each pot.
