SpecGrade is quickly making its way to a list of the well-known and like Cannabis LED companies. Their fixtures are well designed for vertical growing and very solidly built. No other lighting company I know offers a 10-year warranty and easy accommodations of the spectrum changes by swapping out solder-free diode boards. While many other LED companies expect and want cultivators to replace the fixture every 3-5 years. SpecGrade is selling hardware that’s made to last, yet designed to evolve.
