RAM covers the unglamorous half of a grow room - the air moving around inside it and the water in that air. Circulation fans, humidifiers and dehumidifiers are what actually hold VPD steady, and RAM makes reliable versions of all three at prices that let you buy enough of them.
- Oscillating and pedestal fans: 16in and 18in heavy duty oscillating wall fans, 16in solid base and 18in heavy duty pedestal fans - see all circulation fans.
- Clip and floor fans: The AirFlex 8in 360-degree rotating clip fan, 7in oscillating clip fan, 12in three-speed eco fan and three-speed floor fan. Browse clip fans.
- Dehumidifiers: 12L and 20L RAM units plus the Airlab 25L for larger rooms - more humidity control.
- Humidifiers: 5L and 13L ultrasonic humidifiers and the RAM Wall Humidifier, available with a resin DI water filter to stop mineral dust. See humidifiers.
- Water filtration for humidifiers: Inline DI resin water filters and Purolite polystyrenic resin refills - these stop the white dust ultrasonic humidifiers throw when fed hard water.
- Fan control: The RAM Air Pro ii 14A fan speed controller and plug-in fan speed dimmer up to 300W - browse fan speed controllers.
- Other kit: Bug Barrier for pest control and the ETI pH Pal Plus meter.
Why choose RAM?
Air movement is the cheapest yield improvement in a grow room and the one most people underspend on. Stagnant air causes hot spots, weak stems and mould. RAM fans are priced so you can put three in a tent instead of one, and the humidity kit is sized sensibly for real UK rooms.
RAM FAQs
Do I need a DI filter on my humidifier?
If you are on hard water, yes. Ultrasonic humidifiers atomise everything in the water, including minerals, which settles as white dust on leaves and equipment.
What size dehumidifier do I need?
As a rough guide, a 12L unit suits a single tent, 20-25L suits a small room. Undersizing is the usual mistake - a dehumidifier that runs constantly and never catches up is worse than none.
Can I control a RAM fan with a dimmer?
AC fans work with the plug-in dimmer up to 300W. Check the fan rating before pairing.
