Mars Hydro Reviews 

Application - useless
Sensors - useless
Lights - great for manual use (dont ever trust their application)
Tent - leaking
IHub 10 - disconnecting
App - measures data how it wants, measures wrong, stops working.
Fans - squeaking after 4 months
Dripper system - better flood your growroom, it is better than whatever this was supposed to be
Ducting - tearing apart, blow at it with your mouth and there will be a hole - my house smelled like weed x times cus of their useless products.
Humidifier - failed to detect no water and overheated

They should make a living by polishing shoes on trainstation. This is far, far, FAR, beyond their capabilities. I would actually wonder if anyone from that company was capable to wear shoes with shoelaces.

Love it!!!😎. VPD stays in range way better compared to Mars Hydro 5L Humidifier. No more having to go and adjust the humidity settings like on the 5L Humidifier. The biggest improvement for me is sensor, no more two temp/humidity sensors, and it connects to Icontroller, huge plus too. You can see the environmental status all from the Mars Pro app and make changes at home or if you’re on the go.
With that said, I ordered another one to replace the 5L one running another tent.
5 out of 5 ⭐️⭐️⭐️⭐️ ⭐️

Been using Mars Hydro products for years. I bought 2 TS1000s 5 years ago, and I still use them to this day, for germination all the way to flower, and still give amazing results. Ive had both the 6500 and 4500 as well. Amazing lights

Good company and products, I got their entire smart system and they are better priced than average for the tech provided. Their customer support gets back to you and I haven't had a problem with them.

Warranty issues took so long to resolve that this company is not to be trusted

Ordered a few times from mars hydro and everything has been great arrived on time very good product so looking for a good light or tent or even accessories mars hydro is the place to shop

I reached out to mars hydro for advise on my purchase and I was walked and helped tru the whole process and advise .I could not be happier with my 2 lights as well as my closet and adiliights . I tried many brands and mars hydro is the best quality and performance I ever seen . Keep it up mars hydro and thank you for your support

Excellent products
Had a problem with clip on fan. Slight confusion on its delivery.
However their customer service was a tually very good and their corrispondence was always prompt and polite.
Very highly reccommend

I purchased a ts600 light and it did everything as expected. Hasn’t run hot and everything still works just fine nearly after a year of full use. Will be upgrading soon!

Loving my new mars hydro tent kit with controller works very well Ty guys

Come da anni sempre al top Ho acquistato un prodotto in una settimana era già tra le mie mani con tracciatura del pacco dal primissimo momento all'ultimissimo momento complimenti vivissimi all'assistenza clienti all'azienda super consigliato al contrario dei loro contendenti di mercato e non facciamo nomi grazie Mars Hydro

Great company great people 10/10 best lights on the market

I’m a newer grower and wanted to document my experience with Mars Hydro support after a product failure.

I purchased a Mars Hydro grow kit that included their 6-inch oscillating clip fan. After roughly one year of ownership, the fan stopped working. The failure happened very close to the end of the stated warranty period.

When I contacted support, I provided everything requested — proof of purchase, serial number, photos, and video showing the issue. Communication with customer service was polite and responsive, and they did escalate the case for review.

However, Mars Hydro calculates the warranty period based on the order date rather than delivery date or actual time in use. Because of this, my fan was considered slightly outside the warranty window and they declined to provide a free replacement.

After escalation, the final offer was a replacement fan for $20 shipped as a goodwill discount instead of honoring the warranty.

As a new grower, I chose Mars Hydro expecting dependable equipment and support from a well-known brand. Having a component fail so close to the warranty cutoff — and then being asked to pay again for a replacement — was honestly frustrating and not what I expected from the experience.

Mars Hydro all day. Great quality

​I am writing to you as a dedicated customer who has recently fully upgraded to your latest 2025 ecosystem, including the newest smart dehumidifier, humidifier, and the iHub system. While I am very impressed with the build quality and performance of the hardware itself, I am currently quite frustrated with the limitations of the MarsPro app and the overall software automation.
​I would like to share a few critical points where the software is currently failing to meet the standards of a "Smart 2025" system:
​VPD-Based Automation: Although the app displays VPD (Vapor Pressure Deficit) values, it is impossible to use VPD as a primary trigger for automation. I expect the system to automatically adjust the intensity of my devices to maintain a specific VPD target, rather than just basic ON/OFF cycles based on temperature or humidity.
​Lack of Dynamic Dimming/Scaling: Currently, the devices seem to act in a "binary" way (mostly ON/OFF or fixed levels). For a 2025 system connected via RJ12, I expect smooth, incremental adjustments. For example, the exhaust fan should increase its speed gradually as the temperature rises, not just jump to a preset value.
​"Dumb" Environmental Scenes: The current scenes are too simplistic. They don't allow for sophisticated "if-this-then-that" logic that combines VPD, light stages, and fan speeds into a cohesive environment.
​Synchronization Issues: Using multiple apps or sections within the app to control different parts of the same tent feels outdated. The ecosystem should feel like a single, unified "brain."
​I invested in the 2025 line because I believed in your "Roadmap" toward a truly smart, automated growing experience similar to your competitors. Right now, the hardware is ready, but the software is holding my garden back.
​Are there any imminent updates planned for the MarsPro app that will address VPD-target automation and dynamic device scaling?
​I look forward to your response and hope to see Mars Hydro become the true leader in smart grow technology.
​Best regards, Lukas

I have the FC-E4800 LED light and recently had to call the support team because it wasn't working at all. I contacted the support team and they were more than helpful with my situation. The responded to all of my emails quickly and provided multiple solutions until the problem was resolved. I definitely will refer them to anyone I know who's looking to start growing for themselves. Thanks Mars Hydro

The lack of instructions as to how to set up the controller and the humidifier is unbelievable. It leads to much googling and YouTube searching. The products are OK but sometimes the controller over humidifies for no apparent reason. Switching it off and on usually fixes the issue. The advertising is also unclear. I purchased the humidifier believing that it could be controlled online, but the truth is that you also need to purchase the new controller. Up your game on instructions guys.

After 40+ hrs of researching different grow tent companies and reading 100s of reviews from customers, it was clear Mars Hydro was my choice. They had everything I was looking for, at a comparable price. 32x32x63 tent fit perfectly in my area. I ended up buying the IController system including all sensors. If you’re going to grow do it right, any edge you can get to make your grow better do it. I don’t worry now on how my grow is doing, I just bring up the Mars Hydro app and see the status of what’s happening inside my tent.
Setup: Easy, follow directions. First grow didn’t have Icontoller system; just tent, inline/oscillating fan, and humidifier worked excellent. The upgraded Icontroller system is 100% recommended, way way less worrying.

Their equipment and costumer service are amazing
