Timers can be used to automate your hydroponic system
or your grow light or both. This means you do not have
to switch your system on and off everyday yourself . .
. very useful! If you wish to automate any HPS or Metal
Halide grow light over 250w you will need to use a contactor
relay to handle the inductive load of the ballast. This
load (the amount of power a ballast draws to start up
and power the light) can cause timers to fail, leaving
your plants in darkness.
