Description
Large-format centrifugal humidifier for commercial grow rooms up to 150m²
The HR-50 is the larger sibling of the HR-15, built for spaces up to 150m² and delivering substantially more output while still connecting to any standard water reservoir. This complete kit bundles the HR-50 humidifier head with the Analogue Humidistat HR-EHSA, a 100 L FlexiTank and the fittings and pipework needed to plumb it into a tank, so the whole climate-control loop arrives as one order.
What's Included
- Faran HR-50 Humidifier – centrifugal humidifier with carry handle and float-valve water inlet
- Faran HR-EHSA Analogue Humidistat – dial-set humidity controller
- FlexiTank 100 L – collapsible reservoir with a tap at the base
- HR-15 & HR-50 Fitting Kit – garden hose, 6 mm feed pipe and connectors from the tank tap to the humidifier
Low Humidity Across a Large Grow Room
It's aimed at commercial-scale rooms and multi-tent facilities where undersized humidifiers simply can't keep pace with extraction, particularly through propagation and vegetative stages when target humidity sits highest. Sustained low humidity in a large space is a much bigger problem than in a small tent - it affects every plant in the room at once, driving the same leathery growth, wilting and stunted development that smaller humidifiers are built to prevent, just at scale.
As with the smaller HR-15, it must be run on soft, purified or RO water only; hard water will scale up the mechanism and leave a mineral residue across nearby equipment.
Key Benefits
- High output - 2,500 to 4,000cc of humidification per hour
- Covers rooms up to 150m² in a single unit
- Complete kit - includes the analogue humidistat, a 100 L FlexiTank and reservoir fittings
- Dial-set control via the bundled HR-EHSA humidistat
- Built for commercial and multi-room facilities
- Centrifugal atomising – a spinning disc throws the water into a fine mist, with no nozzles or ultrasonic discs to clog
- Self-filling – an internal float valve tops it up from the 100 L FlexiTank or a tap supply under 5 kg/cm², on a 90 W draw
How to Use
- Water: soft, RO or demineralised only – hard water scales the disc and float valve and leaves white dust on lights, reflectors and filters.
- Set up: stand the humidifier level (Faran specify horizontal installation so the float valve controls the water level), with the FlexiTank's tap above its water inlet – the kit feeds by gravity.
- Connect: hose connector on the tank tap, 6 mm pipe into the humidifier's inlet; open the tap and the float valve fills the base.
- Control: plug the humidifier into the HR-EHSA and the HR-EHSA into the mains; Faran recommend mounting it about 150 cm up, out of the mist stream.
- Targets: around 65–80% RH for cuttings and seedlings, 55–70% in vegetative growth and 45–60% for flowering and fruiting – check with a hygrometer at plant height.
- Maintain: check and clean the tank and base regularly. No mist – switch off and check the water level; overflowing – turn the water off and check the float valve.

Frequently Asked Questions
How long will the 100 L tank last?
At the HR-50's top output of 4 L/h, a full 100 L FlexiTank gives about 25 hours of continuous misting – longer in practice, because the humidistat switches the unit off whenever the room reaches its target.
Can I use tap water?
Only if it is soft. Faran humidifiers are made for soft, purified or RO water – hard-water minerals come out with the mist as white dust and scale the disc and float valve. An RO unit or a DI resin filter solves it.
Can I upgrade to digital control?
Yes. The Faran HR-DHTC digital humidistat works with the HR-50 and adds live humidity and temperature readouts plus a second output for a heater or air-conditioning unit.
Can it run from a water tap instead of the tank?
Yes – Faran designed the HR-50 to run from a tap or a tank, provided the feed pressure stays below 5 kg/cm². Where tap water is hard, a tank of RO or softened water is the better option.
