Mars Hydro is one of the leading companies that provide cheap grow lights that are highly efficient. This means optimal lighting for your plants. 

But what makes the company’s products good, effective, and sought-after in the market? Let us find out in this review.

Design & Durability

The grow lights are made affordable without sacrificing design and functionality. Mars Hydro offers good quality products, despite its low price, and this is evident in the construction and quality. 

Type of Lights Used

When it comes to the type of light, the company uses full-spectrum (1) for all its grow lights. This means that their grow lights can support all stages of the cannabis plants’ growth cycles. 

You do not have to worry about using different LED lights to support the plants’ different stages of growth. You just need to adjust certain Mars Hydro grow light products to provide the needed light at different stages. 

LED Material and Casing Construction

Mars Hydro ensures that they only use high-quality but also affordable LED chips, which is why they use mostly Epistar chips for their LED, particularly for the company’s affordable options. It also uses Cree and Osram LED chips, which are also top quality but are more expensive than Epistar. 

As for the casing construction, Mars Hydro uses mostly steel casing to ensure a durable and strong cover for their LED lights. Some products use a thick all-aluminum casing, which improves the heat-releasing capability.

Grow Light Lifespan

The longevity of the grow lights will depend on your usage, and how you handle and take care of the equipment. If you are careful, you can prolong the lifespan of your grow light and not wear it out too soon.

The company says that the lifespan of their grow lights is at 50,000 hours. The figure can either go down or go up, depending on care and handling. 

Safety Features

All of the grow light products that Mars Hydro offers have CE and RoHS certification (2). Some products even have the ETL certification, which shows that their products have passed the rigorous safety testing and inspections. This ensures they are safe to use. This also shows that the products do not contain any hazardous materials.

Most of the company’s tents also come with ventilation fans and aluminum heat sinks to add to the cooling feature and ensure the entire setup will not catch fire.

Some of Mars Hydro’s grow lights use new SMD chips, which has improved technology. The new chips make the LED light consume less power and produce light more efficiently

Grow Light Sizes & Assembly

Series

Mars Hydro offers many different grow light models and each one belongs under a certain series. The company currently has 7 series, and they are the Mars Pro II, Mars II, Mars Reflector Series, Mars Cree Cob, Mars ECO, Mars SP, and Mars TS.

In this section, I will focus more on the company’s 3 more popular series. 

Mars Pro II

The Mars Hydro Pro II LED Grow Light is the best grow light series that the company has to offer. Each product provides the highest Photosynthetic Photon Flux Density (PPFD). This means that your plants get a higher percentage of the protons that the grow light produces. The series also has great cooling features, and they are not expensive. It is a great series for intermediate or commercial cannabis growers.

Mars II

Although Mars Hydro Pro II is the best series, they are not the most favorite. That title goes to Mars II LED Grow Light. Growers prefer this series because of its good light penetration. It also has a high PPFD and the grow lights from this series uses new SMD chips. This makes the LED light more efficient at consuming energy and have longer lifespan.     The series is a good option for intermediate or commercial cannabis growers.

Mars Reflector Series

This is the most cost-efficient from Mars Hydro. The grow lights from this series uses new SMD chips for more power-efficient LED lights. The items have a longer lifespan as well. The models also have an upgraded reflector design, which improves plant coverage. This will allow you to have high THC output. Highly recommended for beginners, intermediate, and small growers.

What Comes with the Box

When you purchase one of the grow lights from Mars Hydro, it will be shipped with all of the items you will need to properly install the fixture inside the tent. This includes the hanging kit, LED lighting with the casing, power cords, adjustable rope hanger, and instruction manual.

Ease of Use

The instruction manual that comes with the grow light box is simple and easy enough to follow, which will make it quicker for you to assemble and install the grow light inside the tent. You can request assistance for faster and easier installation, but you can definitely do it on your own. Just follow the instruction manual.

It is recommended to set up your grow light in a way that you can still adjust its distance from your plants. Doing this will provide you with the flexibility to increase or decrease the distance, depending on your plants’ needs.

Frequently Asked Questions

LED grow lights are more expensive compared to the other grow light options. However, the investment is worth it since grow lights are better overall. They are operating at a cooler temperature compared to other grow lights so the inside of your tent will not get too hot.

Grow lights that use LEDs are also more efficient in terms of consuming energy and they have better durability. The benefits and long-term prospects of LED grow lights negate the upfront cost.

The best location to place the grow lights is to hang them on the roof of your grow tent. If your tent has strong beams that can support the light, then you can directly set up the light there. If the beams are not strong enough, it is advised that you purchase a frame that you will place on the tent and serve as the hanging place of your tent.

The less powerful lights are placed 12” to 20” above your plants while the more powerful and intense lights are placed 24” to 42” away.
