Every single time one of them updates, I loose some sort of functionality in one or both items. First it was the ihub. I updated to the newest version and lost the ability to control light 2. It works perfect directly plugged into the wall outlet and it works if I plug it into the icontroller. The ihub no longer recognizes it. I contact customer service who can’t comprehend what I’m saying. They want pictures. I sent them still they can’t comprehend what I’m saying. I made a video but since they have no access to social media, they asked that I download some app to send them the video since it won’t play in the email. The app they require doesn’t work either. Now the icontroller has updated and it’s not even recognized in my app any longer and neither is the ihub. I can’t see anything. None of the Bluetooth is working. This company is terrible and highly frustrating. I will never buy another mars hydro product. ### 4/5 — Good, most recent update really cleaned things up *2026-06-27, version 2.1.0* I had a very easy time connecting the app with my iControl. It was literally plug and play with the iControl and the other devices hooked up to it. The app is easy to navigate and straightforward. I am having not difficulty with the ability to control all of my Mars Hydro devices consistently and with ease. I am currently using an iFresh (in-line fan), a clip fan, thermometer/hygrometer, and the FC4000 light. Updates are still being released on a regular basis, so hopefully it will improve with time. ### 1/5 — Network unconnected *2026-06-17, version 2.1.0* Updated the app to the latest version and got hit with that… now I can’t use anything!!! ### 4/5 — Good but UI needs improvement *2026-06-16, version 2.1.0* I had a very easy time connecting the app with my iControl. It was literally plug and play with the iControl and the other devices hooked up to it. The app is easy to navigate and straightforward. The user interface (UI), however, is very noticeably lacking polish. The formatting is a bit odd in some places. The good thing is that none of the UI issues interfere with my ability to control all of my Mars Hydro devices consistently and with ease. I am currently using an iFresh (in-line fan), a clip fan, thermometer/hygrometer, and the FC4000 light. Updates are still being released on a regular basis, so hopefully it will improve with time. ### 1/5 — How is this real? *2026-06-13, version 2.0.5* For a company that makes awesome lights and advanced electronics, I find it strange they make the worst app I have ever downloaded. Hours of troubleshooting and calls to customer service, I have an outstanding light that only can utilize 1/2 its features. I want the last 3 hours of my life back. This deserves Zero stars if possible. ### 1/5 — Nothing works *2026-05-26, version 2.0.5* This app doesn’t work either, just like the other one. Garbage product and worst customer support. Nothing connects and is impossible to get a response from Mars Hydro. ### 2/5 — Bleh *2026-05-19, version 2.0.5* So many problems. Meh customer service ### 2/5 — Not very user friendly *2026-03-21, version 2.0.5* So far not to impressed with the fiction of the app. Not very user friendly. Still mile behind AC infinity and VIVOSUN. ### 1/5 — won’t connect *2026-03-05, version 2.0.4* does not connect to my wifi. bluetooth finally links up but then will mot connect to my wifi. help was no help at all ## Frequently asked questions about Mars Hydro ### What devices does Mars Hydro support?
