Switchers

A grow room light switcher is the electrical interface between your timer or climate controller and your high-wattage grow lights or other high-load equipment. Rather than routing full power loads through a controller's relay, which can degrade contacts and create failure points, a load switcher takes a low-voltage signal from the controller and uses a dedicated relay to switch the actual load.

BioFloral carries the full Grozone switcher range: simple on/off switchers at 120V and 240V, heavy-duty light switchers with ETL certification for 8-light and 24-light setups, and smart flip-flop switchers for staggered lighting in commercial rooms. All 13 products are from Grozone, a Canadian-designed brand with a long track record in indoor cultivation.

Best Grow Room Switcher for Every Setup

Best for Small Rooms with a Single Light Circuit

The Grozone LS1 and LS3 provide reliable single-circuit switching for growers who prioritize simplicity. These units allow you to dial in your lighting schedule with consistent results. Simply plug your analog or digital grow light timers into the trigger outlet to maintain precise control over your garden. This setup is ideal for managing a single plant or small group without the need for complex grow light controllers.

Best for Large Rooms Running Multiple 240V Lights

For facilities with high electrical demands, the Grozone LS8 and Dual LS8 utilize a heavy-duty contactor to manage massive loads safely. We recommend these ETL-certified models for any setup where a stable power supply is critical to the health of your flowers and foliage. Professional grow light controllers ensure that your crop receives uniform light across all growth cycles to maximize your final yield. These units can easily handle a large LED strip or multiple T5 fixtures.

Best for Commercial Grows with Staggered Lighting

The Grozone SFF4 Smart Flip-Flop Switcher allows you to operate multiple banks of lights efficiently by alternating power on a defined interval. This staggered approach prevents large spikes in electrical demand while maintaining consistency in your environmental settings. It is a beneficial solution for commercial facilities that need to balance light intensity with limited electrical capacity. Proper timing ensures that each plant receives the exact light it needs without overloading your system.

Best for Full Facility Automation at Scale

The Grozone SLS24 offers precision at scale by managing up to 24,000W across several zones. When integrated with a digital light controller, you can monitor feedback from various sensors to adjust settings like moisture and CO₂ levels individually. This data-driven approach allows you to optimize plant growth and move beyond having to manually manage every piece of equipment. Our technical advisors can help you integrate these systems to ensure your power supply remains stable and your yield stays high.
