The Precision Day & Night Cycle Timer with Display is an incredibly
accurate instrument that's simple to install and even easier to use.
Timer regulates any 120-volt, 15-amp gardening gadget via an "on" cycle
which can be set from 5 seconds to 60 minutes and an "off" cycle that
can be set from 1 minute to 12 hours. Gardeners can also augment their
schedule with separate settings for the day and night.
