What do you think of the Mars Hydro 300 W LED grow light?

Is the Mars Hydro 300W LED grow light the ideal choice for you?

It doesn’t really matter if you’re growing plants in soil or use hydroponics. It’s suitable for various growing environments such as grow tents, green houses, grow rooms or even stealth boxes and closets.

The affordable grow light is very popular among beginners due to its low energy consumption at 132 watts. That’s great being equivalent to the output of a 250 watt metal halide or HPS bulb. Considering the fact that you won’t be needing a ballast, you’re looking at a 50% savings in power. Less heat and less maintenance will bring those savings even higher.

It can operate between 85 to 265 Volts using 1.33 Amperes, at 110 Volts or 0.68 Amperes at 220 Volts in frequencies 50/60Hz. This means it doesn’t really matter where you are in the world. You can use the Mars Hydro 300w anywhere.

Make sure that you set your expectations right with this grow light from the beginning. It’s not going to help your plants to flower like a 400W HPS for sure. At best, it can do the job of a 250W, provided that you’ve got all the variables right. This afforable Mars Hydro grow light will help your plants produce flowers. But they might seem a bit ordinary when compared to plants grown under more powerful and more expensive LEDs in the market. This is probably the most important takeaway in this Mars Hydro 300w review.

One unique feature is that the LED view angle features both the 90° and 120° angles. This is a crucial element in the grow light as it affects the light intensity and subsequently the total effective footprint whereby the 120° is the best angle for a wide coverage area of intense light in the area. The feature makes the MarsHydro 300W a diverse product with two different types of footprints.

Cons of the Mars Hydro 300W LED Grow Light

The Mars300 can flower a single plant, but it is not the best option for the blooming stage. Its small size means it simply doesn’t have the power to maximize yields during flowering. It is great as a supplemental light or a light for vegging or cloning.

The fixture does not have any switches. If you want to turn it off, you have to unplug it. There is also no way to dim the light or to turn off some of the LEDs when full power is not needed.

The final disadvantage is Mars Hydro itself. They’ve had issues in the past with faulty fixtures and long wait times to get them serviced or replaced. MarsHydro have been working very hard to rectify this, so it is unlikely you will have any problems. It’s something you should be aware of though.

Our verdict
In conclusion, the Mars Hydro 300w LED Grow Light is a very good option for beginners. It is great for those who are looking for an affordable light. The Mars Hydro 300w has full spectrum, low energy consumption, high durability and low maintenance. We noticed that young plants responded very well to the light, which is great.

Going by user reviews, it seems to be one of the most popular LED grow lights for beginners. We understand why. It is an affordable light for people who are just getting into indoor growing.

Customer service is a slight concern with Mars Hydro only offering email assistance. You can’t call them up if something goes wrong with your grow light. However, they do respond to your email within eight hours. You can also get replacements or repairs done through one of their two service centers in the US.

The Mars Hydro does some good growing and decent flowering. If you are looking for a professional LED grow light, this is not the light that you want. Especially in the flowering stage this light has its shortcomings.

To sum it all up: this is a great light if you’re new to growing and have a small budget. I do not recommend this starter light for real professionals. Now it’s up to you to weigh in the pros and cons and make a smart decision! Furthermore, we hope this Mars Hydro 300w review helps you in making the best choice.
