Product Description

Heads up! For most growers we recommend the H380.

It's a bit cheaper, more powerful, and is built to handle the entire growth cycle. 

For the experienced grower looking to optimize either their vegetative of bloom phase of growth in a small hydroponics setup, the H350 LED Horticulture Grow Light will do wonders. 

When we say small, we mean about one plant (two if you squeeze). 

The technology that Kessil uses is state of the art. Using its 90W Dense Matrix LEDTM platform, the H350 produces an extremely bright, penetrating stream of light that reaches deep into the canopy of the plant.

It's designed to replace a traditional 200W HPS system but only consumes 90W. Less power = Lower electricity bill! 

Don't worry about heat, the H350 features a vapor cooling thermal management system that directs heat away from the high-intensity LED core quickly.

That means you don't need any additional fans and this thing will keep running for a long long time.

This light comes in two models:

Deep Purple - Get This One For the Vegetative Phase of Growth

Kessil uses a Special Penta-Band Spectral Recipe for the Deep Purple model. Five different LED chips provide a strong emphasis on blue wavelengths. 

This encourages stronger, fuller, healthier plants during the vegetative phase of growth. 

Magenta - Get This One For the Bloom Phase of Growth

If you've already got a lighting setup and want to maximize your bloom yields, go with this one. 

The Magenta model has a Unique Quad-band Formula to improve the flowering phase of growth.

Don't be fooled, just because it has one less band than the Deep Purple doesn't mean it's any less amazing. 

It is heavy in the red spectrum, exactly what your plants need during the bloom phase.
