Review: Job well done! - This unit does exactly what I needed it to do. I have a 3' x 2'.5'', 4' high grow room and it keep the smell away and the temps where I need them to be. I have my unit set to turn on automatically if temp hits 75 or humidity goes above 50%. Noise is Okay, but you can't expect anything quieter when the fan needs to adjust when your grow space adjusts. I do wish the 'min temps' setting would be programmed to STOP the units if temps or humidity fall below a certain point, but it does not work that way. That is probably the only downside, it is one or the other.
Review: It has plenty of flexibility for any grow box/ tent setup. - My ice maker bin is doubling as a seedling grow box and the in-line fan’s adjustability is a positive addition to my box setup. Low noise levels help a lot. Plenty of suction power when the temps go up.

## Features

- 𝐒𝐦𝐚𝐫𝐭 𝐀𝐩𝐩 𝐂𝐨𝐧𝐭𝐫𝐨𝐥：Connect to the MARS HYDRO App to control the fan anytime and anywhere. It includes a temperature and humidity sensor for real-time climate monitoring and automated regulation. The iControl Controller is powered via its RJ12 port and requires no external power supply.
- 𝐅𝐮𝐥𝐥𝐲 𝐀𝐮𝐭𝐨𝐦𝐚𝐭𝐢𝐜 𝐀𝐝𝐣𝐮𝐬𝐭𝐦𝐞𝐧𝐭：Program the fan to monitor climate changes in real time; it will automatically adjust the fan’s on/off status, speed, and airflow according to your preset settings, freeing you from manual operation.
- 𝐏𝐨𝐰𝐞𝐫𝐟𝐮𝐥 𝐈𝐧𝐥𝐢𝐧𝐞 𝐅𝐚𝐧：The MARS HYDRO inline duct fan features a durable plastic housing, and its fan blades adopt a mixed-flow design to deliver active, consistent airflow to your growing space. Operating at 2600 RPM, the fan provides a powerful 205 CFM of airflow to meet your ventilation needs.
- 𝐒𝐮𝐩𝐞𝐫𝐢𝐨𝐫 𝐀𝐜𝐭𝐢𝐯𝐚𝐭𝐞𝐝 𝐂𝐚𝐫𝐛𝐨𝐧 𝐅𝐢𝐥𝐭𝐞𝐫：Crafted from imported 1050+ Virgin Australian activated charcoal, the carbon filter delivers 100% filtered airflow. It offers enhanced absorption capacity to efficiently remove odors, and it comes with a machine-washable pre-filter cloth to prevent carbon residue buildup
- 𝐂𝐨𝐦𝐩𝐥𝐞𝐭𝐞 𝐕𝐞𝐧𝐭𝐢𝐥𝐚𝐭𝐢𝐨𝐧 𝐒𝐲𝐬𝐭𝐞𝐦：This all-in-one kit includes everything you need: a 4” Inline Duct Fan, a 4” Carbon Filter, an iControl Controller, a 25ft Flexible Duct, 3 Stainless Steel Clamps, and 2 Grow Tent Vent Covers. No additional parts are required—unbox and use directly.

### ⭐ False advertising!
*by A***R on April 15, 2026*

I wish I could give it 0 stars. This is the OLD controller that is only capable of controlling lights and the OLD fan that is not controllable, except by a manual knob NOT INCLUDED. And to top it off, the controller power supply is also NOT INCLUDED. Yes, the new versions of these things are powered nicely through RJ12, but this is not. Especially disappointing that this is being sold through the official Mars Hydro storefront.
