Mars Hydro Reviews 

Simple easy hassle free plus hands down in my honest opinion and I have been growing for over 20 years and the Mars-Hydro set up is hands down one of the best on the market period.

I am shocked by this experience. I paid extra for an add-on, and it was NOT delivered. I had the package sent to Austria to avoid customs fees, but now, due to your mistake, I would have to travel again and pay extra — which I refuse to do.

I am not a new customer. I have spent hundreds of euros with this company on a LED grow light, a grow tent, and a full irrigation system. I trusted your service and quality — and now I receive an incomplete order after paying in full.

If this is not resolved immediately by sending the missing add-on to my home in Switzerland or issuing a partial refund, I will update this review and post my experience across multiple public platforms and grower communities.

Waiting for your urgent reply.

Overall, it’s a great company. Products are great. They work very very well. The only thing is I think it’s a little on the expensive side but you get what you pay for and if you want great that’s what you’re paying for so yeah, there’s these guys are awesome.

Quick shipping, everything went smooth. Decent quality products. Their site could be working faster, but outside of that everything else is perfect.

I love MarsHydro

The best quality company at this time very fast shipping 3 days until îi received my product

Discret packaging, the fastest shipping that got to me in 3 working days, materială and the products are verey nice and have the best quallity that other brands give at moutch more price

I've ordered multiple times and different things like lights (ts series, fc series and fc evo series) and tents in different sizes. And I always get my stuff fast and without any problems. There are always great sales.
I've been to Mary Jane Berlin 2025 and got some of my tested. And one of then tested as what I've been told (it was also the last test of the convention for the stand I got it tested at) that it was the highest tested for the weekend at the convention. Some other stuff had also always high results.
Marshydro is great for beginners or someone who knows what they are doing. I've always had great results.

Faire preise, gute Produkte und schnelle Lieferung, top immer wieder gern

Lampe led jamais reçu, service client fait patienter plus de 2 mois pour répondre qu il ne peuvent rien faire pour moi et le mieux me conseil d aller voir la police !! A faire a tous prix

Could defo do with making there items more discret when posting.

UPDATE: Since leaving this review I have have done extensive research and have conclusively proven the light in my “complete system” is not strong enough to adequately cover the full surface area of a 3x3, thereby requiring a light upgrade. Complete system!!! I Does Mars Hydro care? No. Do they respond? No. Will I be taking them to court?
Yes! I WILL BE TAKING MARS HYDRO TO COURT.
**************
Since writing the below review and receiving the boiler plate apology from Mars Hydro, they have DONE NOTHING TO RESOLVE THIS ISSUE. NOTHING. It is CLEAR they do not care about their customers' experiences with their products. It is equally clear that Mars Hydro does not know what is means to "Do the right thing." Avoid this company!

*********************************************

I LITERALLY BEGGED my family to purchase me the Mars Hydro 3x3 63" "GROW TENT KIT COMPLETE SYSTEM" (as advertised on Amazon) for my birthday so I could grow my first cannabis plant from seed to harvest!! Note: it is legal to do so in my home state. And they did!! I was sooo excited. So I bought a seed and off I went on my journey w my Mars Hydro "GROW TENT KIT COMPLETE SYSTEM". As an inexperienced grower, I immersed myself in the ways of cannabis horticulture because I wanted to grow my plant optimally (who wouldn't?) And as a result, I quickly came to realize that the Mars Hydro “all-in-one” solution my family bought me for my birthday is materially misrepresented because it's NOT EVEN CLOSE to being a "GROW TENT KIT COMPLETE SYSTEM" as promised through its explicit marketing.

Over the ensuing months I was forced/obligated to spend over $900 on essential, missing components to make the grow space not only base-line functional but also capable of managing all aspects of a typical cannabis plant's growth phases all the way thru to harvest. The "GROW TENT KIT COMPLETE SYSTEM" critically lacked:

Humidifier
Dehumidifier
Intake fan
Automation tools
Adequate inline fan

All of these missing tools are used in an orchestrated unison to maintain a stable, (mostly) auto-regulated environment (managing: temperature/humidity/VPD) using digitized equipment, for a digitized age.

Note I: My "GROW TENT KIT COMPLETE SYSTEM" came w a 150w LED light w dimmer that is mediocre at best, a fine oscillating fan but the tent (while sturdy and easy to assemble) has ports that are too small. Thanks again Mars Hydro!

Back to the story: Unsurprisingly (or surprisingly if you believe in unicorns), Mars Hydro sells ALL the aforementioned critical, "must have" components separately (and expensively), explicitly acknowledging their necessity, yet omits them from their "GROW TENT KIT COMPLETE SYSTEM". This overarching (nefariousness) marketing strategy has its roots tied to theoretically based business models:

Planned incompleteness: Omitting critical components from a seemingly full-featured product. The deceptive company provides a solution.

Information asymmetry: Exploiting beginner customers' lack of knowledge regarding environmental controls. The deceptive company provides a solution.

Upsell trap: Requiring significant additional investment for baseline functionality. The deceptive company provides a solution.

Clever “deceptive company” right??? The name of this deceptive company is Mars Hydro!!!!!!!!!!!!

Fun fact: If you're wondering if I bought any of the essential "must have" components I needed from Mars Hydro, the answer is NO—BUT I TRIED ...here's why I didn't: they didn't HAVE ANY OF THEM!! You see Mars Hydro is far behind the market place in terms of innovation, so when I did need to buy the essential add-on tools, the “best of the best” could only be found in Mars Hydro's competitors product lines' like VIVOSUN and SPIDER FARMS. Note II: When I did need to upgrade the 4" inline fan that came w Mars Hydro's "GROW TENT KIT COMPLETE SYSTEM" (it was far too weak...) I tried to buy a Mars Hydro 6" inline fan but THEY WERE OUT OF STOCK!!! So I went with a more powerful VIVOSUN 6" inline fan (which also came w a bigger carbon filter and automation). Just sayin’…

As I type, I have yet to hear back from Mars Hydro in any meaningful way regarding the review/complaint I am writing here--which I submitted to their customer service team on Monday, July 28th, 2025. Maybe this 1-Star WELL DESERVED rating will get their attention. What matters most is that other first time growers MUST BE KNOW THAT MARS HYDRO "GROW TENT KIT COMPLETE SYSTEM" IS NOT THE SOLUTION YOU'RE LOOKING FOR IF YOU WANT TO GROW YOUR PLANT CORRECTLY. MORE SO, THE COMPANY BEHIND THIS SHAM PRODUCT CLEARLY HAS NO VALUES, INGENUITY OR CUSTOMER SUPPORT FOR PATRONS IN THE UNITED STATES.

TO SUM IT ALL UP: MARS HYDRO IS A DECEPTIVE & DISHONEST COMPANY!!! AND IS A COMPANY TO AVOID!!!

I STAND BY EVERY WORD.

Brilliant tent and humidifier! But would recommend saving a bit of money and get it without the iconnect controller as will give you nothing but greef other than that would highly recommend.

Rapide, de très bonnes qualités tout ces produits

Tengo el ifresh 4 mas el filtro de carbono en un 80x80 y desde que lo uso, ya no tengo problemas de filtrado de olor, va genial, encima tienes la app para poder modificar la potencia y no hace falta tenerlo enchufado a un enchufe inteligente ya que desde la app puedes apagarlo o encenderlo , entre otras funciones como mirar la temperatura, ajustes segun la humedad , en fin tiene buenas caracteristicas y buen funcionamiento. Ahora estoy apuntando al foco mars hydro fc e 3000, me han hablado muy bien de el y he visto resultados en otros cultivadores, realmente muy buenos.

Un azienda ottima in tutto. I prodotti sono di ottima qualità pur essendo economici. La spedizione è rapida e il servizio post vendita eccellente.
Lo consiglio a tutti

Super zufrieden mit MarsHydro
Hab super Ergebnisse durch das komplette grow System, sehr einfach zum aufbauen und anschließen, auch bei kleinen oder größeren Problemen gibt's eine schnelle Antwort vom Support.

Fast shipping and the products are real great quality!

Greatness awaits amog

The product looks great!
It was delivered safely and within 3 days. I can't say much about the light yet, but I'll update my review based on how it benefits my plants later on.
