We have some 16" baskets each containing 21 Bacopa Gulliver in JI

handy water supply which can easily be automated to make life easier.
Grateful for any recommendations as to the most effective type of
nozzle to use - spray, mist, drip or into watering spikes.

And make - go on Amazon and compare the feedback of the major makes.

I got the impression Gardena seems better rated than Hozelock.

I've given up on Hozelock water computers. Every one I've owned has
leaked internally within 2 seasons and either corroded part of the
electronics circuit board and/or battery connections. This is despite
removing the unit during the winter so water doesn't freeze inside.

I've found that a very cheap watering computer works, and lasts, just as
long as the more expensive branded products

I just use a micro tube system with adjustable drip ends touching the
soil. Being able to adjust the individual drip rate helps with balancing
a micro-tube the system. Water takes the path of least resistance and so
you have to choke off drip outlets closest to the tap.

Recommendations:
Smear grease or Vaseline around the battery terminals to give them some
degree of protections if they get wet.

When assembling a micro tube system dip the end of the tube into near
boiling water to make the tube soft before attempting to push the tube
over the couplings or drip end fittings.

You will have to adjust the watering computer timing around 3 times
during the season. The amount of water required in the summer would make
your baskets too wet early and late in the season.
