# Master Your Grow with the SolarSystem Controller: Precision Spectrum and Timing Control

The SolarSystem controller works only with the California LightWorks SolarSystem 1100, 550, and 275. It can control an unlimited number of lights from a single controller. It allows automated programming for spectrum control, 24-hour timer, and day/week/month calendar. Now it is possible to program an entire grow cycle automatically – varying the spectrum, the length of the day, transitions from veg to bloom, final finishing modes, sunrise/sunset – all in a low cost easy to program digital controller.

The SolarSystem controller features programmable 0% to 99% spectrum control over three spectrum ranges – Blue, White and Red. You can use the controller in manual mode only to adjust the light spectrum or use the digital clock and calendar to run custom light recipes over a day, week, month or entire season. Programs can be saved for specific crops or strains. You can also use the view mode to work in natural white light and then switch back to high power reds and blues for accelerated growth.
