Suppose you want to water a large area of ground which you have just
sown, and add some liquid fertiliser at the same time. The area is too
large for a watering can, or even a portable spray if you are going to
do it properly. You just want to use a hose. So it would be handy
to be able to screw on a spray attachment which would release small
quantities of minerals and other nutrients in the recomended dilution,
ie in proportion to the water-flow.

Try any good Horticultural suppliers (NOT garden centres or the major
sheds, they don't do this sorta thing) and ask for an 'inline hose
diluter' for the domestic market an 'hose end feeder' has been
available for many years.. The latter are cheap, the former more
expensive but better IMO as they allow a variety of feeds/solutions to
be mixed (they are used by growers for applying feeds/pesticides etc to
crops.)

About 40 quid + IIRC. try LBS etc..
