This fan works as expected and moves all the air that I need to move. It has a lot of functionality to it. In manual mode the fan can be run at any speed. In auto mode I use it to evacuate high temperature air or high humidity in my 4x4 Mars Hydro tent. There many more options as well. I also had great communication with Mars Hydro from shipping to installation. Products like this help toward letting the tent do the work for me.

Way to much effort to replace a simple part! Have to email to China and wait for a response. Mars needs a USA based rep. to deal with USA based issues. Customer service is slow but at least it's there. Had to purchase another light unit to keep the grow moving forward.

If you have supplemental lights from another company that doesn’t provide mounting brackets mars has got you covered. Their supplemental lighting brackets fit spider farmers supplemental light bars perfectly.
I wasn’t happy with shipping cost and reached out to support and it was fixed. They never said but I think their website needed some maintenance

Purchased a Marshydro FC-6500 and it has become faulty and stopped working completely within the 12 month warranty period I have emailed them received a reply asking for photos of transformer and power source so I sent them that was over a week ago have emailed them every day since still no reply think it’s very unprofessional to ignore and not honour your warranty policy for customers who always use you probably something simple like a faulty transformer would of been happy for a new one to just be sent out rather than to be ignored it’s left me it a real mess with things not happy

Ordered the Mars Hydro inline 6 inch fan with thermostat on Tuesday 2nd October 2024.
Money taken from my account and zero email confirmation and cannot view my order on their website.
Very disappointed is an understatement, especially when their warehouse is in my city here in Sydney.

Great service but unfortunately the bottom lining of my 2.3x2.3 grow tent is way too small to fit around all four corners so the floor of the tent is exposed. I bought it to upgrade my hydroshoot Secret Jardin tent, but I would recommend secret jardin over Mars Hydro as their bottom linings/covers actually fit
