Mars Hydro Grow Light Reviews

It is no secret that indoor gardening can be expensive. However, if you don’t have the right grow lights, the project can be downright frustrating. Most new growers think LED grow lights cost a lot more than fluorescent, MH, HPS, and HID lamps, and that’s the major reason that prevents them from trying the lights.

However, this generalization no longer holds true because there are many manufacturers who make affordable LED grow lights without compromising on quality. One of them is Mars Hydro.

Mars Hydro has been manufacturing LED grow lights and grow tents since 2009. The lights have the most excellent spectrum and feature IDS technology, competing with the best brands on the market.

MarsHydro 300W LED Grow Light Full Spectrum - Review

For a grow light to promote photosynthesis, it must provide the right spectrum of light. But a good grow light can require a huge initial investment. Thankfully, Mars Hydro designed this grow light with a small budget in mind. It provides a full spectrum and can be used for plants grown in soil as well as hydroponics. When it comes to energy savings, it gets top marks as it only consumes 132 watts while giving off 300 watts. The bright light it emits is similar to that produced by a 150W HID or HPS grow light. The light is very safe to use, all you need to do is plug it in and turn it on. But while it is very efficient, it provides a very small coverage (only 2ft x 2ft). If you have a large grow operation that spans 4 x 4 cubic feet, you'll have to get four lights to provide sufficient light to your plants.

MARS HYDRO ECO 49 LED Grow Light Full Spectrum - Review

If you're just starting your indoor grow operation and don't want to shell out a ton of money, consider getting this LED grow light. It is a full spectrum light designed for small-scale indoor gardening. Its 12-band spectrum includes infrared and triggers maximum photosynthetic reaction in plants.

The LED panel only weighs 6.75 pounds, so you can easily move it when you need to. It doesn't emit a lot of heat and does not require ballasts. Since it maintains a low heat level, you can place it close to plant canopies and it won't harm them.

This light has a lower energy consumption than the first light, it only draws 100 watts while giving off 300 watts. However, it lacks the wavelengths needed to grow all plants indoors. The good news is you don't need to get a fan or turn on air conditioning as the light is equipped with a powerful cooling system that consists of fans and heat sinks.

Marshydro Reflector 480W LED Grow Light Full Spectrum - Review

While this grow light is a bit costly, it is well worth the cost. It comes with everything you need to grow your plants, except the plants. The light uses 96 5W LED chips made by Epistar which have a very good light intensity.

When raised 18 inches above plants, it provides a PAR of 680 μmols. The light beams it produces are similar to those produced by a 650-720W HID or HPS light. It is also very efficient at using energy as it only needs 190 watts to discharge 480 watts.

While it is a bit heavier than other LED grow lights in its category, this only means high-quality materials have been used to make it. It is very simple to use; simply plug in the power cord, fix the hangers, and plug it into a power outlet. But to be honest, we don't like the placement of the power cord. It gets in the way if you don't clip it up.

MARSHYDRO ECO 98 LED 600W Grow Light Full Spectrum - Review

While the Eco 49 and 98 share similar features, they differ in some areas. The Eco 98 is bigger and a lot heavier than the Eco 49. Because of this, it provides ample light for two plants, whereas the Eco 49 can only grow a single plant.

The light discharges a bright purple beam, illuminating a 2ft x 4ft grow bed at a height of 18 inches. Your plants will love its bright light and respond very well to it. It uses very little energy (192W) to provide very intense light (600W), and offers 70% energy savings compared to HID lighting systems.

The grow light features more red lights and is perfect for the blooming phase. It will help your plants to produce bigger flowers, larger fruits, and have better yields. Its reflector cup ensures the light produced is uniform.

One thing you may not like about this light is that it doesn't have separate lights for the vegetative and blooming stages.

MARS HYDRO Pro II Epistar 600W Full Spectrum GrowLight - Review

This is one of the pricier lights by Mars Hydro, but you can use it for an entire grow cycle. It gives off more red and blue light to ensure plants produce better yields that are of high quality.

Three things make it superior to its LED counterparts: an advanced cooling system, an upgraded power supply, and Epistar LED chips. These also give it a long lifespan and ensure it generates proper light for your plants.

Two switches for the vegetative and blooming stages allow you to control the amount of light your plants receive at different stages of growth. The light can substitute a 300W HPS or HID light and its advanced reflector cup design ensures 100% of the light produced is used by plants.

However, the light only provides coverage for two plants (covers a 2ft x 2.5ft growing area) so you will have to get more lights to illuminate a larger area.

MarsHydro 600W Led Grow Light Full Spectrum Grow Light - Review

The wavelengths plants need to thrive usually depends on their stage of growth. From seedling to pre-flowering stages, they need blue light. Once they start flowering, they need more red light. The Mars Hydro 600W LED grow light has a full spectrum that is ideal for different stages of plant growth. However, it lacks infrared and ultraviolet light.

It doesn't use a lot of power (only 132 watts) or discharge a lot of heat and keeps operating costs to a minimum. It features a built-in circuit board that makes sure that if one component gets damaged, the others continue functioning optimally. The light uses 120 Epistar LEDs with a lifespan of 50,000-100,000 hours and will last you a few years. You will probably have upgraded to a bigger light before you have to replace it. And your main reason for replacing it may be its small coverage (only 2ft x 3.5ft).

MARS HYDRO Mars ll 900w Full Spectrum Grow Light - Review

Growing plants with LEDs can be enjoyable, exciting, and very rewarding, but the wrong light can make you more angry than happy. Some LED grow lights don't offer enough coverage while some cost an arm and a leg. This light manages to be both affordable and powerful at the same time. What's more, it provides sufficient coverage for 4-6 plants (its maximum coverage is 5.5ft x 5.5ft). It offers all these benefits while only drawing 364 watts.

The 900-watt light has a full spectrum that comprises infrared to boost resin formation and THC yield. Like the sun, it is ideal for all types of indoor plants. It is equal to a 450W HPS lighting system but doesn't have the overheating problem the traditional light has.

An excellent cooling system ensures the light runs cool even after many hours of use. A large heat sink and four fans make for excellent heat dissipation. But while the light uses 180 5w Epistar LEDs, some may burn out after several months of use.

MARS HYDRO Reflector LED Grow Light Full Spectrum 720W - Review

The two things that make the Mars Hydro reflector lights popular is that they are reasonably priced and come with everything you need to start growing plants immediately. The best feature of the Mars Hydro 720W Full Spectrum Grow Light is its low power consumption. It only uses up 298 watts at 110 volts and 290 watts at 220 volts. It dishes out 720 watts and the light it produces is so intense it can make you blind if you keep staring at it.

Mars Hydro knows that the type of LEDs in a light make all the difference and uses 5-wattt Epistar chips, some of the best on the market. The light has a 10-band spectrum that ranges between 430nm and 730nm. It provides a coverage of 2.5 feet x 4.5 feet which is enough for 2-3 plants. However, it lacks a dimmer which can be very effective during certain growth stages.

Marshydro Reflector 960W LED Grow Light Full Spectrum Grow Light - Review

As a horticulturist, your job is to provide the best conditions possible for your plants, so they can give you high yields in return. This light has both vegetative and blooming modes and can be used for an entire grow cycle. Another great way to use it is as a backup light during the vegetative stage. Its compact shape allows you to position it however you want for maximum coverage (4ft x 4ft). Since it consists of 192 5W Epistar LED chips, it provides more light spread throughout the grow tent.

The light is quite heavy, which means it’s durable, but its strength really comes through in the intensity of the light it produces (960 watts). The light is so powerful it may burn your plants if you aren't careful. But the good news is the grow light runs cool and only draws 388 watts of electricity at 110 volts. However, some of the people who have used this light have reported diode quality issues.

MarsHydro Pro 2 Epistar 800w Full Spectrum Grow Light - Review

No matter the grow light you choose, the most important thing is the spectrum. If you pick a 1000-watt light whose spectrum does not stimulate plant growth, your plants will suffer. Thankfully, the Pro II Epistar 800W Grow Light has a full spectrum that ranges between 440nm and 730nm. It generates more blue and red PAR per watt to help plants produce better yields.

The light uses 160 high-intensity Epistar LEDs. The LEDs are placed on a reflector cup for enhanced spectrum mix. Zener protectors ensure each diode functions separately. Your plants will be able to absorb light more efficiently and grow faster. The light is equal to a 400-watt metal halide or high pressure sodium lamp. It draws 386 watts of true power while producing 800 watts.

However, this light is not without flaws. We don’t like the fact that its full spectrum doesn’t include infrared or ultraviolet light.

MARS HYDRO Pro II Epistar 1600W Full Spectrum LED Grow Lights - Review

The most powerful of all the lights listed here, it’s hard to go wrong with this light. Mars Hydro created it with a focus on energy-efficiency as it only consumes 632 watts. Its superior spectral output covers full PAR (440nm-730nm) and promotes photosynthesis. It always runs cool thanks to quiet fans and big pin-cushion heat sinks. A top-notch cooling system ensures low canopy temperatures and gives the light a long lifespan. Other features that make it durable are the constant-current LED controllers and powder-coated steel hardware.

This light makes a great substitute for an 800W HPS light and runs 60% cooler than the conventional light. It is safe to use as it is ETL certified. At 18 inches above plant canopies, it provides a coverage of 4.4ft x 4.4ft during the flowering stage and 5ft x 5ft during the vegetative stage. Mars Hydro ships it with everything you need to start your indoor grow operation. However, you must get several lights if you run a commercial grow outfit.
