Mars Hydro Reviews 524

When we were looking to buy a grow tent, we checked them all out---and at the time the 3 x 3 smart tent just came out-++ so it was a no brainer! Mars Hydro products are awesome! The grow tent, fans, exhaust unit--- everything working fantastic and easy to "dial in"!! We bought a 4 x 4. Now we are just waiting for a Monster Grow Tent 🎪⛺! On the real, for the quality and price tag!! Please don't hesitate! Peace

Best in the business

They have stange terms. When purchaced a product there was free gift promised on their web Page. But their promises of free gift don't apply anymore then they ship the goods. They said the offer was expired. I'll take my business elsewhere.

Been a loyal costumer for over 5 years. Been through tons of innovations keeping up with the ever GROWING demand

Excellent products at a fair price . Constimer service was pretty good also

There 150w light was a great upgrade from my vivosun 100w light

Mars hydro lights is great I just received my new fc 6500 and it's very bright it's a big difference from my old light it seems to be very well made and it was plug and play right out the box

Used one of there LEDs for over a year prior to experiencing issue with driver. Unit was replaced under warranty and noticeable improvements over the previous driver.

I'd previously rated them 5* supplying spares and assistance, however my recent experience was anything BUT 5*. I'd - directly from the UK site - ordered a couple of controllers and sensor(s) kits totalling £239.00 for those items, along with some other fans and sundries making a total of a little under £300 after discounts. The controllers duly arrived with the fans and sundries but not with the additional sensor kits which make the best part of £150.00 of the total. I duly, and politely, emailed to ask about the sensors and got told they would be delivered in December. That was, from date of Point of Sale, at least 3 weeks later. There was nothing on their site to tell me that this was the case, and nothing proactively mentioned to tell me after ordering, either.

Long story short, I bought them as kits and needed the additional and optional sensor kits. Waiting 3 weeks was not an option in the circumstances but, there is more! FWD-FAST 3 days, grudgingly accepting the delay on the sensor kits, thought I would at least set up the controllers and basic/included sensors, only to realise that the controllers I have been sent do not connect to Wi-Fi. The older model of these controllers does not connect to Wi-Fi, which seem to be the models I was sent. If you go on MH's website and search for the older model you cannot buy it in the UK, only their 2025 model with Wi-Fi but I digress; I emailed them again, following contacting them about the missing sensors, 4 times in total and those emails went into the ether... a vacuum; I had no response whatsoever and at time of writing this I have still not heard back from Mars Hydro.

If, by dint of my own issue, these controllers (controller43) ARE the correct ones, they haven't confirmed or helped me to understand them; there are no instructions for Wi-Fi connection supplied with them, just the basic stuff for example. I am left floating in the breeze with no information to help.

I responded to their original email about the delayed sensors, too. Tumbleweed. Nothing. No help, no confirmation, nothing.

I was sold sensors that were not in stock and I was not told about this; I received seemingly although not confirmed older controllers that don't appear to be Wi-Fi connectable AND if they were, I have received no help anyway.

Summarising, I have now approached Paypal and raised a dispute. This is a prime example of customer service that should be embarrassing to them. A simple response to my query about the controllers would have sufficed as would being told the sensors are not actually available, or at least would be 3 weeks' waiting for them, giving me the choice at time of purchase. Instead, 2 hours of writing emails, 30 minutes raising a dispute with Paypal, and now, writing this review, which pains me greatly; I have a lot of MH kit but that was bought via third party sellers.

I would suggest never buying direct; use a 3rd party reseller who have clear indications of stock levels, rather than leaving it to whatever drop-shipping warehouse MH employ here in the UK. The limited support is extremely disappointing.

I just needed information and being told the truth about stock levels. Being ignored is painful.

Dec 2025 Edit

I have now finally been contacted. Let's see where this goes.

April 2026 Edit

As can be seen it took almost a month to respond to my original review! The sensors took 6 weeks to arrive and the information about the controllers satisfied my concerns that I had been sent the correct ones. I emailed them to say as much

Summarising, I stand by what I said in respect of buying through a reseller with stock. Customers should not be waiting days and weeks for items out of stock or information or answers to their queries.

I won't use their filters again (genuinely rubbish) but the controllers and sensors, once installed, are decent.

I love 💕 mars it's the best light I have ever growing with I have used other lights and they don't even come close to Mars I would strongly recommend the equipment to anyone

I purchased several brands of grow tents in the past but for the quality at the Mars price tag is amazing. I'm running two 3 x 3 smart tents and we love them. Peace

So started with mars hydro as a beginner , first grow finished and can't complain about it , everything did what it should be done , got a nice harvest , just the app connections and updates could be a bit better .

Stunning delivery times, products, and increasing range
And cheaper than Spider farmer!

Fantastic build quality. Excellent value for money. I will be back for more.

Awesome quality and simple to use products, quick and reliable service

One of my inline-fan broke but they sended me a replacement immediately. They have very honest and satisfied customer service. I'm sure I'll stick with them for further purchases.

Quick delivery and great products. Two grows in and 2 tents invested now! 3rd know on the way and excited for many more.

Parcel arrived really fast an packaging on point ;)
Really good quality material and easy to set up , smart built
Got Ihub pro + TSW2000 + Fan and sensor for grow room & VG40 + Humidifier
