Why Black Dog Led
Black Dog LED is a trusted choice for indoor growers due to its numerous advantages. Their LED grow
lights offer a full spectrum, including UV and IR, promoting optimal plant growth and increased yields
while being energy-efficient. These lights are durable, incorporating advanced technology like dimming
capabilities, and often have a large coverage area, making them suitable for various scales of
cultivation. With a proven track record of consistent performance, Black Dog LEDs are favored by
growers seeking reliability and quality results.
The Phyto-Genesis Spectrum is meticulously designed to foster compact, high-quality plant growth,
emphasizing flowers, fruits, and leaves. Utilizing 8 distinct LED colors, it harnesses photomorphogenesis,
triggering plants' hormonal responses to minimize stem growth and enhance flower and fruit production. This
results in more efficient space utilization and increased yields.
Ultraviolet: 3% ultraviolet light (greater than 400nm) mimics the
sun's natural UV light, keeping plants bushier and more compact, more resistant to pathogens and insects,
and producing more terpenes and pigments. Unlike supplemental UV light bars, PhytoMAX-4 evenly distributes
UV light across the entire growing area, and at a concentration that gives your plants the benefits of
ultraviolet throughout the entire growing cycle, not just restricted to the last couple weeks of flower.
Infrared / Far Red: Infrared / far red light (700-750nm) increases
photosynthetic efficiency through the Emerson Effect. Too much can cause stem elongation but when paired
with the right ratio of red and blue light as in the Phyto-Genesis Spectrum, it increases yields.
Violet: Violet light (400-450nm) better penetrates dense plant
canopies to nourish lower leaves, allowing high-quality flowers and fruit to grow lower on the plant.
Blue: Blue light (450-480nm) triggers chlorophyll B photosynthesis
more efficiently than green or yellow light, and helps keep leaves more compact for better canopy
Red: Red light (600-700nm) drives photosynthesis, but can also cause
plants to elongate their stems if not matched with an appropriate amount of blue light.
SP versus SC Models
The only difference between the SP and SC models is the power cord and the voltage it can handle.
SP model IEC power cord
Rated for 100-250 Volts
Not recommended for greenhouse use
SC model locking, water-tight power cord
Rated for 100-277 Volts
Locking, water-tight connection
Unparalleled Yield and Quality
PhytoMAX-4 lights are designed to grow the highest-quality and highest-quantity harvests. Rather than
striving for the highest-possible photons per watt, PhytoMAX-4 is designed to give the highest yield per
watt while maximizing terpenes, pigments and cannibinoid production.
PhytoMAX-4 increases efficiency and maximizes lifespan by actively cooling the LEDs. Cooler LEDs run
more efficiently and have a longer lifespan, especially for the specialty UV and violet LEDs we use.
While fans are a moving part, we've never had one fail in tens of thousands of lights over the past 13
years, plus our patented design includes multiple redundant fans. Even if one were to fail, your light
will keep running just fine.
Energy efficiency is vital for sustainable growing. The lights minimize energy use without sacrificing
performance. Reduced heat output means lower cooling costs, creating a comfortable environment for
plants and savings for growers.
What makes the PhytoMAX-4 20S LED Grow Light unique compared to other grow lights on the market?
The PhytoMAX-4 20S stands out due to its focus on achieving the highest yield per watt while maximizing
terpenes, pigments, and cannabinoid production. This design philosophy sets it apart in the market.
How does the dimming feature work on the PhytoMAX-4 20S, and what are the recommended dimming controllers
compatible with this LED grow light?
The PhytoMAX-4 20S is dimmable from 15% to 100% using industry-standard 0-10V dimming controllers,
providing growers with flexibility in controlling light intensity throughout the plant growth cycle.
Can you provide details on the active cooling system of the PhytoMAX-4 20S and how it contributes to the
efficiency and lifespan of the LEDs, particularly the UV and violet LEDs?
The active cooling system of the PhytoMAX-4 20S actively cools the LEDs, enhancing efficiency and
extending their lifespan. Cooler LEDs, especially UV and violet ones, run more efficiently and have a
longer lifespan. The system includes redundant fans for added reliability.
What is the spectrum range of the PhytoMAX-4 20S LED Grow Light, and how does it optimize terpene,
pigment, and cannabinoid production in plants?
