Galaxyhydro 600 Watt LED Grow Light Product Review

The Galaxyhydro has been around for years under the brand name Galaxy Hydro. This LED grow light has been a favorite amongst many LED enthusiasts but has since been bought out by a new company – Roleadro.

When you purchase the Galaxyhydro 600w LED grow light, you receive the LED system and its power cord. This light is fully functioning right out of the box, so you can plug-and-play immediately after receiving it.

Since this light doesn’t allow you to customize the color of the lighting, you may be frustrated during either the vegetative or flowering phase – especially if you want to hit your plants with only red or blue.

Alternatively, the UV and IR features are ideal for those that want their plants to have access to the most natural aspects that are found from the Sun.

Features and Benefits

The Galaxyhydro 600-watt LED grow light is full of features and benefits. Let’s take a look at what this LED grow light has to offer you.

High-Quality Epiled LED Chips

Epiled chips are battle-tested LED lights. These aren’t an off-brand that’s used in budget material, but instead, high-value chips that are guaranteed to last many growing seasons.

These chips are rated to last between 30,000-50,000 hours. This comes out to nearly 6 years of constant use, which is incredible when you consider you’re supposed to switch your HID bulbs after every two grow cycles.


The engineers over at Roleadro decided to give their customers the benefit of daisy-chaining their products together to make a more efficient system. Through daisy-chaining, you can place upwards of 5 Galaxyhydro 600-watt systems on one circuit.

UV and IR Lighting

The Galaxyhydro 600-watt LED emits ultraviolet rays and infrared lighting, which are naturally produced from the Sun. Ultraviolet rays are known to inhibit the growth of bacteria and fungus, which are common problems when it comes to cannabis cultivation.

Infrared lighting has recently been studied to increase the vitality of plants, which also translates into larger yields and healthier crops.

2-Year Warranty

It’s impressive to see such an extended warranty, especially when the company is in the cannabis industry. Many companies are only seeking to make a few dollars and move on, but Roleadro stands by their Galaxyhydro 600-watt LED product with a no-questions-asked 2-year warranty.

Alternatives to The Galaxyhydro 600w LED Grow Light

As with any product, there’s always competition. Here are a few competitors that we found that closely resemble the Galaxyhydro 600w LED.

VIPARSPECTRA UL Certified Reflector-Series 600W LED Grow Light

Both of these products draw 260-watts from the wall. The warranty offered for the Vipaspectra is an eye-popping 3-years. This is an additional year compared to the Galaxyhydro.

This is a true competitor for the Galaxyhydro and is worth a look if you’re looking at purchasing the Galaxyhydro. This product is ideal for those who want an additional year on their warranty as an added buffer.

Phlizon Newest 600W LED Plant Grow Light

The Philzon 600-watt LED grow light comes equipped with a plethora of features that make the Galaxyhydro pale in comparison. It comes with a thermometer, humidity monitor, rope ratchet, a double-switch for plants in the vegetative phase or flowering stage.

This new LED grow light is well worth your consideration if you’re already looking into the Galaxyhydro. The Philzon 600w LED grow light is perfect for those who want all the necessary accessories included.

BESTVA 600W LED Grow Light

The Bestva 600-watt LED grow light offers the advantage of a dual-chip design. Although it doesn’t offer as many advantages as the Philzon.

The Bestva offers its users with 10-watt chips, rather than the 3-watt chips found on the Galaxyhydro LED. This means that the Bestva is far more powerful than that of the Galaxyhydro 600-watt LED grow light.

The Bestva is for those that want the absolute brightest light on the market, at half the cost of most competitors.

Is the Galaxyhydro 600 Watt LED grow light too Good to be True?

This must the be question that’s had you doubting the Galaxyhydro 600 Watt LED grow light from the get-go. Although LED technology has proven itself to the agricultural industry, the cannabis community remains skeptical.

A glaring reason why many in the cannabis industry refuse to use LEDs is because of the mindset: if it isn’t broken, don’t fix it. This philosophy has kept many talented growers away from this cutting-edge technology and stuck within the grips of power-hungry HID lighting.

Although it’s proven that LEDs reduce electricity bills significantly, many growers are willing to pay extra since High Times and other cannabis-centric lifestyle brands continue to show HIDs in the spotlight.

LEDs, just like HIDs, are lights that can be used to grow cannabis. The difference between the two is in the amount of light output, the heat generated, and the electricity consumed.

Novice growers that think they’ll produce a bumper crop harvest with a 1,000-watt HPS light may be
sorely disappointed when it comes to harvest time.

This is because the yield of a cannabis plant is based upon the skill of the grower, not the intensity of the light.
We know that lighting is necessary for a plant to grow, but there are 2 other significant factors that come into play when growing cannabis.

A professional grower will yield similar amounts, regardless if using HID or LED. When it comes to novice growers, LEDs actually make far more sense because they allow you to keep your environment under control.

LEDs produce less heat, which reduces the stress on your plants and will enable you to focus on the actual act of cultivation; rather than fumbling with cooling systems.

So, are LEDs too good to be true? Yes and no. As stated above, it’s up to the skill of each and every grower to produce a decent yield.

A beginner can have access to the best growing technology, yet ruin the harvest due to a lack of experience.

A professional can be left with minimal tools and inferior equipment, yet still, pull down a massive crop oozing with trichomes.

LEDs are a new and exciting method for growing cannabis, so it’s up to you to blaze the path and understand the various ways the LED systems can benefit you and your cannabis garden.

It’s for this reason that we’re providing an in-depth review of the Galaxyhydro 600w LED grow light – to put you in a position of understanding and confidence.

What You Need to Know Before Buying a LED Grow Light

As with anything, it’s unwise to jump head first into something that you don’t fully understand.

If you’re considering to buy a LED grow light, then read along to become acquainted with this type of product before you make a substantial purchase.

Who’ll Benefit from Owning a LED Grow Light?

The individuals that will benefit from owning an LED grow light are those that absolutely want to reduce their electricity bill.

If you’ve grown cannabis with HID lighting, then you know how big of a surprise the electricity bill can be during the summer months.

HID lighting increases the heat in your room, so not only are you using an abundant amount of energy with the lights alone, but you also create the need to cool your room down with additional electricity through the use of an AC unit.

This pairing puts stress on your electricity consumption, which eventually results in an eye-popping electricity bill.

Growers who are looking to become cost-effective will benefit from using a LED grow light because they emit far less heat, which decreases the strain on your AC unit.

Another type of grower that will benefit from owning a LED grow light is one that is compelled to reduce his or her carbon footprint.

Each HID light provides a massive amount of lighting, but at an environmental cost. The more electricity that’s consumed is directly the result of power plants producing this energy.

Growers who cultivate cannabis in small places are also a large contingent who’ll benefit from using LEDs. Smaller rooms require less intense lighting, and they become heat traps when a HID system is placed within.

There’s no reason why you’d place a 1,000-watt HPS light inside of a 2’x2’ grow tent as this would destroy your crop quickly unless you have an incredibly efficient AC system in place.

Just like growers using small spaces, hobbyist growers that would like to experiment with cannabis cultivation will benefit from LEDs because they incur small electricity bills, reduce the need for AC systems, and are far more eco-friendly.

Who Won’t Benefit From an LED Grow Light

The main individuals that won’t benefit from an LED grow light are commercial producers.

Those who are obligated to provide hundreds or thousands of pounds of cannabis will normally use traditional lighting (HIDs) or commercial-specific plasma lighting.

Although professional growers use LED grow lights, major producers are used to cultivating marijuana with metal halide and high-pressure sodium bulbs.

Most commercial operations are fully outfitted with AC systems and environmental controllers that allow the grow room to be completely automated.

This doesn’t mean that their method is efficient since they can drastically reduce their operating costs by incorporating LEDs into their operation.

What You Need to Think About Before Buying an LED Grow Light

Now that you know who will benefit from owning an LED grow light let’s take a look at what you need to think about before becoming a part of the LED community.

Why Are You Buying an LED Grow Light, Anyways?

You need to remember why you’re doing this in the first place. It’s crucial that you remember that you aren’t willing to pay the high price of electricity due to HID lighting.

LED grow light technology is new, but it’s been proven by the agricultural industry. When you consider it, the high price of electricity makes your cannabis cultivation endeavors null because you’re essentially paying more rather than if you paid the retail cost of cannabis products at a storefront dispensary.

Now’s the time to produce cannabis on your own time, all while paying less and becoming self-sufficient.

How Many Plants Will You Grow?

This is a fundamental question that you must ask yourself, regardless of the type of lighting system that you intend on using. The number of plants that you grow will directly affect the type of LED grow light that you should purchase.

Most cannabis-friendly states allow residents to grow up to 6 mature cannabis plants, but this isn’t always the case. There are states that allow only 3, and others allow upwards of 9.

Some states allow you to act as a caregiver to others and increase your plant count. This issue is further complicated if you’re one of the lucky few to have received a cultivators’ license from your local jurisdiction.

In general, 4 plants within a square meter will benefit from a 600-watt LED grow light. The higher you raise your lights to accommodate for more plants, the PAR (photosynthetic photon flux) value becomes increased.

When the light density for photosynthesis increases, the less light your plant receives. This is why it’s crucial for you to consider your plant count and plant size to make sure that your

LED grow light is sufficient. If your LED grow light is too large for your space, you become inefficient. The same occurs if you buy a too small LED grow light, which leads to inefficiency.

To realize the benefits of LED technology, you must find the ideal balance by accommodating the correct number of plants.

How Large is Your Grow Room?

If you’re growing within a 2’x2’ closet space, then you’ll have a far easier time finding an adequate LED grow light.

If your grow area is a 15’x 15’, then you’ll need to place multiple LED grow lights at strategic points to ensure your entire marijuana canopy is covered.

When growing in larger areas, you’ll need to have a pre-determined plan that considers how tall your plants will be, how many plants, and their exact location.

If you can provide all of these details, then you’ll be better equipped to purchase the correct amount of LED grow lights.

What’s Your Budget?

Unfortunately, LED products still command a high price. These devices are cost-effective in the long run, so it’s essential that you understand that there will be a significant upfront cost when purchasing a new LED grow light.

Similar to the solar industry, the upfront cost scares away many, but the long-term savings pay for the unit and then some in as little as a year of use.


As you already know, the time is now to reduce your electricity bill by using LED technology.

The Galaxyhydro 600 watt LED grow light has shown through countless years that it’s more than capable of decreasing your electricity use.

With so many advantages and features, we can only recommend that you give this blossoming technology a chance that it deserves.

Once you purchase the Galaxyhydro 600 watt LED grow light, it’ll surely be a part of your grow room through many years of harvests.
