LED grow lights are a tough thing to understand – there are hundreds of companies selling through different brand names, making outlandish claims, and so on…

What’s a grower to do?

Today, I’m reviewing one of the most accessible options in the industry. I’m talking about MarsHydro, a Chinese company whose very affordable LED grow lights have slowly gained acceptance among growers. As a Chinese manufacturer of lights, you still have to bridge the America-China gap in communication with the company sometimes, but they are coming a long way. And better yet, they offer truly low-cost grow lights.

In this in-depth MarsHydro review, I’m going to take a look at their product line, build quality, and the company itself review from top to bottom. We’ll look at:

  • The features their lights offerThe build quality of their lightsAll of the technical specificationsTheir warranty policy and company history

…and much more. Without further ado — let’s dive in to Mars Hydro.

My Quick Take on MarsHydro

If you want my quick opinion, here you go:

Mars Hydro’s grow lights are quite affordable relative to their quality, especially the new version of the Mars Hydro 300W. It uses new SMD technology and they’re able to be daisy-chained. They perform much better than older versions, which has a bigger problem with burnt diodes. It’s a great choice for a beginner grower.

Their current lights are split into these categories:

  • Mars Pro IIMars IIMars Reflector SeriesMars Cree COBMars SP (Available soon)Mars TS (Available soon)

There are too many models to individually cover in this review, so I’ve decided to cover the Pro II and Reflector Series, which are their most popular lines.

Recommended Models

The only Mars Hydro light I personally can recommend is the 300w Full Spectrum, as it’s the one that I’ve used in my personal grow room.

  • XC3LBI2XC3LBI2XC3LBI2XC3LBI2

The newer version has more red diodes to achieve bigger flowers, larger fruit, and higher yields. It’s got an upgraded power switch, plus you can finally daisy-chain them to allow more scalability to your grow room.

Should You Buy a Mars Hydro Light?

If you’re interested in the MarsHydro 300W, then yes…it’s still a good value. They’re coming out with some higher-end white LED models, which I am going to get my hands on soon for an in-depth review both here on the blog and my YouTube channel.

Company Background

When I was looking up all I could find about Mars Hydro I noticed that they had very little information about themselves in their website. So I wrote them an email expressing my concerns over their lack of information asking them for more, and they answered!

Here are some parts of their answer:

It’s important to remember that there’s a cultural divide between how business is conducted in America and in China, so the practices of a Chinese company may seem strange to us as Americans, but it’s simply a culture gap most of the time…not anything malicious or unprofessional.

What Type of LEDs Do They Use?

Marshydro utilizes mostly Epistar LED chips, but in some of their higher quality models they also utilize Cree  or Osram LED chips.

Here’s some information about their spectrums according to their product description.

White LEDs in the ranges of:

  • 2700K3000K

Nanometer specific LEDs with the following outputs:

  • 455nm460nm465nm470nm615nm625nm630n640nm645nm650nm

Infrared (IR)

Mars also offers centered PAR (micromoles) measurements readings with most of their grow lights.

Mars Hydro Warranty

Mars Hydro provides a 3 year true warranty. Whenever you buy a LED grow light, it’s important to check the warranty that the company offers. I can’t tell you how many times I hear about people buying lights and then the light dies on them in the first month of operation. To protect against that, the better companies offer a warranty that covers any initial light failures. The best companies offer even more protection than that. The quality of a light manufacturer’s warranty is a direct signal as to how much they believe in the product that they’re making and selling to you.

Mars has improved their warranty page since the initial draft of this review, adding more information as well as including a full return policy and replacement parts cost sheet.
