Water Tanks

This is just what I've been told - never seen it in action............
A friend with an allotment had an IBC to collect water and had a solar powered pump to pump the water into a hose for watering his plot.
I don't know the details and he no longer has his plot but it seemed like a good idea at the time.

I could put a hose on my tap and rely on water pressure but I try to only water stuff until plants are established and then 'Grow em ard'  Some plot holders started watering their stuff, bringing the roots to the surface then forgetting to water. Plants died or gave rubbish crops. Bettwr not to water at all rather than a light drenching now and again methinks.
