Mammoth Lighting 400W Veg Series LED Grow Light

ECO Farm


Type: Unknown Type

Mammoth Lighting has been developed by indoor growers over many years of careful experimentation and testing.  Scientifically engineered to deliver the highest level of PAR output and balanced Coverage in the LED grow market.

We customized our light spectrum to optimize plant growth and increase growth while consuming less energy and reducing operating costs compared with traditional horticulture technologies.  

This is the New "Veg + Mom" Series with a high blue spectrum to keep plants compact and manage growth while heading into the flower stretch.

Blue spectrum lighting during the vegetative cycle maximizes the efficiency of photosynthesis for healthy and strong plant growth.

Backed by strong academic research and decades of indoor growing experience with Metal Halides - Mammoth has delivered a first of its kind LED.

This is the new slim fold series. No separate power driver - as the drivers are built into the side rails. This is a true plug and play model. Open the box and plug in.
