These are the big boys - master control units for multiple HID light
HID light controllers can control the ON / OFF function of four
(4) or more HID grow lights at the same time. These rugged units are built to withstand high humidity and
carry lengthy warranties.
Be sure to check out the flip-boxes - They let you to run
two identical grow rooms, side by side, using only half of the ballasts (each
ballast runs 2 reflectors).
These light controllers need to be hardwired so we recommend a
licensed electrician install them in your grow room or greenhouse.
