Some tools are clever. Others are essential. But every now and then, a bit of kit comes along that is both - an intelligent powerhouse wrapped in a rugged little box that quietly takes full command of your growing environment. The RHINO 2EC + RH Fan Controller. From the horticultural masterminds at Rhino, who’ve spent years perfecting the art of indoor climate control, the RHINO 2EC + RH Fan Controller is not just an accessory - it’s the nerve centre of your grow room. If you’re serious about precision, efficiency, and creating the most stable growing environment possible, this is the controller you've been waiting for. Not Just Smart. It's Practically Telepathic. Where most controllers operate like thermostats with attitude, the RHINO 2EC + RH Fan Controller is a fully-fledged environmental manager. This isn’t just about toggling fan speeds. It’s about crafting a microclimate with surgical precision. At its core is a digital sensor that continually monitors temperature, humidity, and light intensity. The controller responds automatically and intelligently to fluctuations, adjusting fan speeds in real time. And the best bit? You can programme separate day and night settings, so your fans behave differently depending on the light cycle. This means no more trying to find a “happy medium” between hot days and cool nights. Just set your preferences, walk away, and let the RHINO 2EC + RH Fan Controller run the show. Negative Pressure. Control By The %. Now let’s talk about one of the most powerful features: the fan balancer. If you’ve ever struggled with unwanted odours escaping, temperature spikes, or humidity swings, it’s probably because your intake and exhaust fans are out of sync. The RHINO 2EC + RH Fan Controller solves this with a built-in fan balancer that can establish negative pressure accurate to within 1% of fan speed. In simpler terms, your exhaust fan always slightly overpowers your intake, ensuring stale air is removed faster than fresh air comes in. The result? Better air exchange, cooler temperatures, and a more stable growing environment. And when the system detects a temperature or humidity increase, only then will it activate the intake fan - keeping energy consumption low and wear on the fan system to a minimum. Climate Control On Autopilot. This isn’t some industrial leftover slapped into a new box. The Rhino 2EC + RH Fan Controller was designed by growers, for growers. It’s as easy to install as it is to use, with a compact enclosure (22cm x 18.5cm x 5cm), weighing just 0.58kg, that mounts neatly wherever you need it. From the touch-and-set simplicity to the intelligent automated responses, everything about the controller is built to make your life easier and your results more reliable. You can even fine-tune minimum and maximum fan speeds, giving you complete control over how far the system ramps up or winds down. This means you’re never left with too much draft - or not enough - no matter how extreme the external conditions get. Grow Smarter. Whether you're working in a stealth tent or running a professional grow room, the RHINO 2EC + RH Fan Controller is ready to plug in and get to work. It’s fully compatible with Rhino Ultra Silenced, Ultra Non-Silenced and Mixed Flow EC fans and pairs easily with a 0.3m 3-Pin adaptor cable. The level of flexibility here is outstanding. Whether you’re growing for yield, quality, or sheer experimental fun, this unit gives you the control and consistency needed to push your setup to the next level. Rhino. The Best A Grower Can Get. The RHINO 2EC + RH Fan Controller is not just another fan controller. It’s an environmental management system built to military-grade specs for the civilian grower. Its ability to adapt to light cycles, react to environmental changes, and regulate airflow with 1% accuracy puts it in a class of its own. If you’re tired of chasing conditions, fiddling with fan knobs, and praying the humidity doesn’t spike while you’re asleep, then stop guessing and start controlling. For growers who demand absolute control, this is the smartest upgrade you can make. Grow smart. Grow stable. Grow with Rhino. Trustpilot
