Now, As per my tradition, I’ll start with an introduction to the brands.

Meizhi vs Mars Hydro – Brand Comparison:

A wise buyer is one who pays attention to the brand value and its presence on the market. The brand’s success generally speaks to the success of the brand’s products. If no one is using Meizhi or Mars Hydro, then it’s probably not be a wise move to test their product and regret later on unless you’re okay taking a risk.

For Meizhi, this manufacturer has been in the grow light market for eight years. They have a considerable product line of grow lights and accessories. Many of Meizhi’s grow lights have been “updated” or refined as time elapsed and Meizhi made an effort to compete for market share.

Meizhi has worked on the feedback provided by users in the past so that new users get real value for their hard earned money.

Mars Hydro has also been on the market for a long time and succeeded in securing a permanent place in their customer’s heart.

Mars Hydro sells a large line of grow lights, grow tents, an accessories. Several of their products have been updated through several iterations to remain competitive with other grow light manufacturers.

So yeah, both brands are genuine and completely reliable as far as indoor growing is concerned.

Each brand has garnered significant positive feedback on several websites.

Build & Design of Mars Hydro and Meizhi Products:

It’s good to consider build and design factor in your checklist as it helps in measuring reliability and durability of the products.

Yeah, better materials are always a key to longer lifespan as we all know.

For comparing build and design, I’ll look at the Meizhi 300W and Mars Hydro 300W models.

Now, if you talk about Meizhi Updated 300W, this LED grow light is built using high-quality materials. The design is ETL safety certified.

Meizhi’s commitment to improvement and value is evident even on their lowest end model, the 300w LED grow light. The current iteration includes a reflective light panel and a newer chip packing method – EMC (epoxy molding compound) designed to improve the life and performance of the LED chips.

Moreover, their previous version was neither equipped with two separate mode switches not featuring daisy chaining function. Their latest 300W model is sporting both the elements in its design.

Meizhi upgraded their 2 models 300W and 600W to include this functionality.

For better light production and effect they’ve used Epistar/Bridglux LED chips of 5W Each in their panel.

Advanced Zener diode is placed perfectly for extended run use and safety of entire panel. If one LED chip fails, the rest of the chips remain functioning.

Moreover, Two separate mode switches for blooming and vegetation is there on the side of the panel for those who prefer this feature.

Taking a look at the Mars Hydro 300W, Mars Hydro has put up a tough, maybe even unbeatable fight as far as competition goes.

The recently updated Eco 300 watt model from Mars Hydro is an improvement over the previous model. The new features include infrared (IR) capability as well as a lower power consumption of 100W±10%.

Apart from that, materials for the inner build is either manufactured in-house or used from highly reputable brands on the field.

Reflector placement for better and brighter light helps focus all of the LED output onto your hungry cannabis plants. Also, high-quality LEDs of 5W each is what you’ll get in the Mars Hydro 300W.

All the panels in Mars Hydro’s updated Eco Series feature daisy chaining and give you freedom of expanding your grow space at any point in time.

Meizhi Spectrum vs Mars Hydro Spectrum:

In my research I noticed two defining differences between Mars Hydro and Meizhi spectrum.

First is that Meizhi claims their lights emit a full spectrum, but they don’t offer a spectral chart. Despite their high reviews and satisfied customers, that’s a negative for me. There’s a good chance Meizhi emits a perfectly fine spectrum, but it’s comforting to see for myself.

Mars Hydro offers spectral charts for their grow lights. The Mars Hydro 480 watt reflector’s spectrum can be seen Here.

The second differentiating factor between these two lights is the Mars Hydro light includes infrared light, while the Meizhi specs list doesn’t seem to mention it.

As I often state in my reviews, the prime objective behind using an LED grow light is to replace sunlight. Plants need a goldilocks “just right” amount of infrared exposure which reduces the time to flowering. Many LED grow lights tend to include infrared, but some do not. For the minuscule price difference between these two lights, it’s probably worthwhile to go for the infrared included with the Mars Hydro.

Now, for comparing spectral capabilities, we’ll look at the Meizhi 450W and Mars Hydro Reflector Series 480W.

best led grow lights

The wavelengths in Meizhi’s spectrum includes 450~475nm 620~630nm, 650~660nm, and white.

In comparison, the Mars Hydro Reflector 480W LED Grow Light then the light features a complete 12 bands full spectrum plus two infrared bulbs to advance flowering.

The Mars Hydro 480w reflector’s spectrum ranges 440nm-460nm, 630nm-660nm, 730nm(IR), and 2700k-3000k. The IR light in the 730nm range helps cell formation and leaf building in your plants.

A complete spectrum with 12 bands in Mars Hydro also helps in improving the process of Photosynthesis and result being well grown healthy plants in your grow space.

The clear winner on the very important factor of spectrum is Mars Hydro.

Intensity – PPFD In Both Brands

We always say users shouldn’t look at HPS/HID replacement figures as those are to trap a buyer by representing a massive figure in the description.

Yeah, real game winner is PPFD results. Because it’s the measurement of the intensity of light on your grow space.

In this PPFD reading comparison, we’ll look at the Meizhi 600W and Mars 600 watt.

Looking at PPFD results obtained in manufacturer tests by Meizhi, they measured 780 uMol from the height of 18”. On the other hand Mars 600W obtained 660 uMol from the same height.

Clearly Meizhi has the upper hand in this respect – but there’s one item to consider. The Meizhi 600 watt grow light is using an extra 80 watts of power from your outlet. So determine which is more important for your circumstances.

Tip:

Highly intense and centralized light is the key element of a COB LED Grow Light. You can visit following link for more information.

Meizhi vs Mars Hydro on coverage:

Coverage is a very important factor when setting up your grow space. You want to make sure the light is emitting sufficient intensity over the whole space.

If you go with one of the lower powered models such as the 300 watt grow lights, you’ll get a solid 1×1 foot of coverage. The 300 watt grow lights provide a good value, but you’ll need multiple units if you want to cover a 3×3 or 4×4 foot space.

Move up to the 900 watt models and you’ll get 2×2 feet of coverage.

Also, by changing hanging height, you can achieve less or more coverage depending on your need, but I don’t recommend to increase it above their recommended figures.

Meizhi vs Mars Hydro on power efficiency:

Power efficiency is a vital element in the grow light decision-making process. That’s because a wise indoor gardener won’t desire to make a massive hole in their pocket in the longer run.

This is the factor which decides whether a light is able to be considered one of the Best Indoor LED Grow Lights or not?

For a better overview, I’d consider Meizhi 900W and Mars Hydro’s Reflector 900W.

The Meizhi pulls around 418W±10% from your wall while Mars Hydro 900W draws around 365W during full operation.

Throughout most of the comparison, the Mars Hydro has proven better at almost every level.

If you want to invest in a reliable and trustworthy product and also wants to save a lot in a longer run, then Mars Hydro is the brand you should focus on.

Meizhi vs Mars Hydro for cooling:

As I already mentioned in the brand and design part of this comparison, both brands are using high quality and reliable materials.

Also, Both the brands had equipped their products with silent yet powerful cooling fans.

Moreover, all the products mentioned in this comparison includes an aluminum heat sink which handles the job of heat dissipation elegantly.

Meizhi vs Mars Hydro – Warranty & Customer Support:

The aspect which is majorly neglected by users.

However, it seems both brands are known to offer customer friendly 24/7 support. I’ve personally reached out to Mars Hydro one time and received a very prompt response.

If you look at warranty period of both the brands, Mars Hydro provides 3 years customer-oriented manufacturer’s warranty along with 30 days refund policy.

Meizhi also provides a 3-year local warranty with the responsibility of shipping charge for parts and afterward for 2 years they’ll provide parts, but you’ll have to pay for shipping.

However, Meizhi also provides 30 days money back policy, so you are always free to return the product in the case you don’t feel satisfied while using it.

Our Verdict on Meizhi VS Mars Hydro Comparison

In my opinion the Mars Hydro wins this comparison as it outperformed Meizhi at almost every turn. With that said, it doesn’t mean Meizhi owners are dissatisfied with their purchase. The product still has great reviews written about it.

The only question now is – which is the best of the Mars Hydro grow lights? Again it’ll depend on your grow space, but I think the 900w provides a good coverage for couple of plants. Going with a smaller output you’d have to consider if the smaller coverage is right for you.
