Black Dog LED’s patent-pending PhytoMAX-2 series of LED indoor grow lights builds on more than 6 years of experience with indoor garden lighting, incorporating numerous technological and engineering advancements to deliver unprecedented PAR levels and efficiency to maximize growth.

 

A team of engineers and plant scientists spent months of design, testing, and refinement to create PhytoMAX-2. Black Dog LED has set the highest standard in grow light technology with a 6-12 month average return on investment, PhytoMAX-2 is the best value per watt of any commercial indoor LED grow light.

 

The Most Powerful and Compact Home Grow Light on the Market

The PhytoMAX-2 400 grow light is the ideal solution for the home grow. Our Phyto-Genesis spectrum contains UV and IR which provide your plants with everything they need to thrive.

  • The most efficient light spectrum for growing plants

  • Based on over 6 years of research and testing, outperforming HPS, MH, CMH (LEC), induction, fluorescent, and "white", so-called "full-spectrum" LEDs in equal wattage tests.
  •  

  • One ideal spectrum for both vegetative and flowering stages

  • Eliminates stalling associated with spectrum changes such as switching from MH to HPS
  •  

  • True full spectrum

  • Ranging from UVA to NIR (365-750nm) goes Beyond PAR™ for ultimate flowering and vegetative plant cycles
  •  

  • Appears white to human eyes

  • Allowing easy determination of plant health
  •  

  • A Better Plant

    • Increases THC, CBD, terpenes, flavonoids, antioxidants / vitamins and pigmentation with UV light. Includes near infrared (NIR) light to boost photosynthetic efficiency through the Emerson Effect. Decreases internodal spacing to direct more of your plants' energy to flowers and leaves, instead of stems
  •  

 

More efficient and powerful than any double-ended (DE) HPS

  • PhytoMAX-2 1000 LED grow lights better penetrate dense canopies to produce a superior yield with higher quality flowers and more trichomes
  • Increases yield by 60% or more over a 1000W HPS. Saves on electrical, cooling, reflector and bulb replacement costs

Higher Yields

Increased yields every harvest means more profit

Better Quality

More cannabinoids, terpenes and potency

More Savings

Saves on electrical, cooling, reflector
and bulb replacement costs

  • More efficient and powerful than any 600W HPS

    • PhytoMAX-2 400 LED grow lights for indoor plants better penetrate dense canopies to produce a superior yield with higher quality flowers and more trichomes
    • Increases yield over a 600W HPS while using 35% less electricity
    • LED grow lights save on electrical, cooling, reflector and bulb replacement costs
    •  

  • 168 High-Output 5-watt LEDs

    • Every top-bin LED is selected from the industry leader for the particular wavelength, including Cree, Osram, etc.
    • With glass lenses for durability and cleanability
    • High light intensity and energetic spectrum, crucial for canopy penetration to nourish lower leaves and flowers
    • Even, edge-to-edge coverage eliminates leaf burn and hot spots
    •  

    • Large Coverage Footprint

      • Up to 4.25' X 4.25' (18 square feet!) of flowering footprint coverage!
      • Proven by independent spectroradiometer testing

Testimonials

I had done hours of research before l made the purchase. My Kind 600 is gathering dust in the corner. Lack of density, frost and depth of light penetration. Black dog lights DUMP par! So went on and purchased this 400....AND THEN ANOTHER! I no longer worry about light intensity. Did l mention lowers are as frosty and dense as tops!?!

I purchased a Phytomax 400 about 4 years ago. I noticed that one of the light banks had stopped working during my last flowering period. I contacted Black Dog, and they made the repairs pain free! The entire process took less than two weeks and my light is back up and running again! This little light kills it every time Ive used it!
