Auto-generated from all reviews of this business. For reference only.
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.

Really good company. The products and pricing are great and my order showed up a lot faster than I expected. I love how you can just get a full ready made kit to go, such a good idea and as I said for the pricing for what you get you legit can’t beat it. Customer service is pretty fast. I didn’t quite understand something with there shipping so I emailed them about it and they got back to me within a couple of hours and sorted everything out perfectly. So 10/10 for me and will definitely order from them again.

They just wont post my comment on their Website which shows me what kind of business Mars Hydro is... I bought 2 Mars Hydro Clip Fans on Nov 28 2025. Today Jan 20 they are already broken... on one of them the fan is just not spinning anymore no matter what I do and the second one wont even start when the power setting is above 3... So wasted money.... I have two Clip Fans from SpiderFarmer and they are working for two years now with no problems at all.... will never buy from Mars Hydro again!

My first 100watt led grow light works great! I also received my 4x4x80 grow tent and waiting on my 730 watt led light. So far, marshydro has gone above and beyond for me. Thank you!

I have purchased 9 lights from Mars hydro, 2 of them show damaged LEDs after a couple of months. 1 of them completely stopped working. The support will show passive resistance, asking the same questions and demanding the same pictures etc. multiple times. I have over 27 massages in the conversation with no resolution yet. If I am lucky, I might get one replacement, but I will have to pay Import fees and wait for delivery from China. At this point, the passive resistance of the support and fake warranty caused more damage than just buying a replacement from a serious and trustworthy brand.

It is constantly tell me it's out of water, it is not, the float on the inside has a weight that always keeps it in the down position, ergo, out of water.. there is no way to fix this..
Total garbage.. DO NOT Buy Chinese gear, it's cheap, and garbage, and there is no technical support for it of any use.. it's garbage, it's going back..

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
