390 Watts of Proven Yield Success in a LED Grow Fixture!

The VividGro V1 LED grow light fixture is unique in its design. Developed by former NASA plant and lighting scientists, its broad spectrum color and optimized PAR output were designed specifically for indoor plant growth. Independent lab testing proves the VividGro V1 LED grow light delivers higher density, higher yields, and higher energy-efficiency compared to traditional growing techniques, with no compromise to quality of the product.  At only 390 W, this fixture is ideal covering a 4'x4' area during the vegetative growth stage.

Forever Green Indoor's take on this light: "What we like about this fixture includes the ideal spectrum for the flowering phase or veg phase and great price performance.  The spectrum is geared directly towards photosynthesis with a high peak in red however it also blends the right amount of blue so both chlorophyll A and B love this light. The Vividgro V1  is a commercial grade high bay grow lamp with a proven track record in cannabis cultivation. We love this light - and it's discontinued so get them while you can."
