Black Dog LED PhytoMAX-2 Review

The truth is that full-spectrum LED grow lights are still new on the market. As a result, a lot of questions have been raised over the advantages they offer over their traditional counterparts. The questions are unsurprising seeing that, in a bid to maximize their yields, most professional growers are constantly on the lookout for the latest technology. Most known brands tend to release new lineups that are better each year. However, some manufacturers still fall short of their claims. Well, not Black Dog LED. The Colorado-based company is known in the industry as producing some of the most of the highest intensity LED grow lights in the industry while always living up to their wattage claims they make. In this article, we are going to review one of the newest and most powerful full-spectrum LED grow lights on the market: the Black Dog LED PhytoMAX-2. So without further ado, here is our Black Dog LED PhytoMAX-2 review.

Benefits of Full Spectrum LED Grow Lights

California Lightworks SolarSystem 550

Many professional growers who have already used full-spectrum LED grow lights seem to agree to one thing – their effectiveness in terms of the spectrum emitted. In order for photosynthesis to occur optimally and as naturally as possible, it is important for plants to grow under the right kind of light and temperature.

Plants tend to prefer different wavelengths according to their type, and this is where full-spectrum LED lights come in. Full-spectrum LEDs have been specifically designed to emit all the wavelengths needed during the entire growth process. This one is just one of the many advantages of this relatively new technology.

Yet another outstanding benefit of full-spectrum LEDs is that they are designed to emit or discharge far less heat when compared to other lighting systems. This is very important as too much heat tends to cause decreased plant growth.

Too much heat also leads to a decreased lifespan of an LED. The average lifespan of a full-spectrum LED grow light is 50,000 hours, which is quite impressive seeing that the average lifecycle of an HPS is only 10,000 hours. This translates to over 15 years of usage with a full-spectrum LED grow light.

More benefits that come with these grow lights are that they are highly versatile and quite eco-friendly, unlike their traditional counterparts which usually contain toxic chemicals.

Overview- Black Dog LED PhytoMAX-2 Review

The Black Dog LED PhytoMAX-2 600 is a full-spectrum LED grow light which is ideal for use by both experienced and inexperienced growers.

Measuring about 18.75″ in length, 18.75″ width, and 5.13″ in height, and weighing in at 39 pounds, this full-spectrum Black Dog LED gives a 6.5 by 6.5-foot coverage during the vegging stage and 5 by 5-foot coverage during the flowering stage. This is very impressive seeing that most 1000 watt LED lights out there can offer a mere 4″ x 4″ coverage in flowering.

Just like all Black Dog LEDs, the PhytoMAX-2 600 features the Phyto-Genesis Spectrum. The Phyto-Genesis Spectrum was developed after years of research in a bid to promote healthier, higher-quality and more disease-resistant plants.

Plants operate optimally at a particular wavelength of light at each stage of growth, and this is exactly what the Phyto-Genesis Spectrum is meant to provide without necessarily having to adjust from one spectrum to another.

The Phyto-Genesis Spectrum does not, however, emit any UV-B light as is the case with most LEDs. The PhytoMAX-2 600 has time and again been advocated as the best LED for growing cannabis, but is also an excellent choice for other types of plants, as well.

PhytoMAX-2 600’s Exclusive Phyto-Genesis Spectrum

The Phyto-Genesis Spectrum is an ideal spectrum meant for both the veg and flowering phases. With this technology, growers eliminate the need to switch or adjust from one spectrum to another. In other words, the Phyto-Genesis Spectrum works perfectly for both the vegging and flowering phases just as it is, thus making it effortless to use.

As most experienced growers know, changing spectrums in the middle of the growing process is very likely to stall growth. A sudden change in light or spectrum usually shocks the plants and as a result, they stop growing for some time (usually for a period of two weeks or thereabouts).

The Phyto-Genesis Spectrum, therefore, eliminates this shock and consequently speeds up the flowering phase, which eventually leads to a larger yield.

PhytoMAX-2 600’s 15-Spectra Combination

The Phyto-Genesis Spectrum in Black Dog LEDs not only eliminates the need to switch from one spectrum to another, but it also combines 15 different spectra, each targeting specific phytoreceptors or photopigments. This helps to maximize growth and robustness, thus improving quality in the process.

In short, armed with this spectra combination, growers should expect nothing less from the PhytoMAX-2 600 than a healthier, higher quality, and more disease-resistant crop. 

PhytoMAX-2 600’s Low Heat Output

One of PhytoMAX-2 600’s biggest advantages, just like all Black Dog LEDs, definitely lies in its impressively low heat output. Even when packed with powerful 5-watt diodes, the PhytoMAX-2 600 does not overheat nor suffer the consequences of overheating (such as a shortened lifespan). To keep their LEDs from overheating, Black Dog has incorporated bigger fixtures and some of the largest heatsinks the industry into their design. Additionally, the LEDs operate uniformly without creating hotspots (a common problem with poorly designed indoor plant grow lights on the market today). 

PhytoMAX-2 600’s Long-Life Fans

With a heat output of 2148 BTU, the PhytoMAX-2 600 is a pretty incredible grow light when compared to most competing panels. And this is especially true bearing in mind that it uses 5-watt diodes.

This impressive low heat output can largely be attributed to its extra long-life fans which have a lifespan of more than 70,000 hours. And the fact that these fans happen to be extremely quiet makes them even more impressive. While most grow light manufacturers are known to use cheap fans, this is evidently not the case with Black Dog LED.

PhytoMAX-2 600’s PAR Value

PAR values usually don’t give an accurate overview or picture of a grow light’s ability to grow plants. This could very well be the reason why Black Dog never gives the PAR ratings of their LEDs.

A more accurate way to estimate the average PAR value of an LED is to look at its total photon flux or number of photons released per second per unit area. For the PhytoMAX-2 600, Black Dog has given a total photon flux value of 961 umol per second (a reading that is much higher than most of its competitors).  These high values make the PhytoMAX one the best grow lights for weed cultivation

Deep Canopy Penetration

Unlike most LEDs which have poor canopy penetration, the PhytoMAX-2 600 actually boasts of a deep canopy penetration. This is because the grow light uses 5-watt chips, something that gives it the intensity or ability to penetrate deeper into the canopy when compared to most LEDs on the market.

PhytoMAX-2 600’s Warranty

The PhytoMAX-2 600 has a 5-year warranty. Black Dog pays for all repair costs for the first 3 years. After 3 – 5 years, the company pays for spare parts only, and after 5 years, the customers pay for all repair costs. This is definitely among the best grow light warranties in the industry today. Black Dog LED manufactures very high-quality products and is confident enough to back it up with a great warranty. 

Growing Tips

Recommended Height

The recommended height for best results is 47 inches above the plants for the vegging phase and 36 inches above the plants for the blooming/flowering stage.

Additional Tips

The PhytoMAX-2 600 comes with a quick start reference guidebook titled Maximum Yields – The Dirt Simple Guide to Using LED Grow Lights. In this booklet, Black Dog has condensed their best tips and suggestions and presented them in an easy-to-understand language. This booklet should be of immense help, especially for the inexperienced grow.

Black Dog LED PhytoMAX-2 Review: The Bottom Line

In conclusion, the PhytoMAX-2 600 is an LED grow light that can guarantee growers the best in terms of plant growth and high yields for every grow cycle. This is largely due to the grow light’s 5-watt diodes and impressive heat management capability. The Black Dog LED PhytoMAX-2 grow lights are certainly not the cheapest, but the saying “you get what you pay for” definitely applies here. If you want the highest quality crops, the PhytoMAX-2 is definitely an investment worth making.
