The GSI-1, Gorilla's groundbreaking digital lighting controller, connects with over 500 Gorilla DE 1000W grow lights across two zones using standard telephone cables. This compact unit can control lights as far as 1,000 feet away with no start-up surge.
While the Gorilla DE Pro Series can work with your existing lighting controller, the GSI-1 can simulate sunrise and sunset, gradually warming up your plants. It also features brown-out / black-out detection and timing for optimal light restart, a built-in clock and 30-year rated battery backup.
The GSI-1 knows when temperatures in your indoor garden are too high and can automatically respond by dimming your lamps to mitigate environmental stress and plant damage. Output power can be fine-tuned from 600W up to 1150W in 1% increments.
