Collection: Humidifiers

Low humidity in early veg or during a heatwave stresses young plants and slows growth — a humidifier adds moisture back into the air rather than relying on trays of water. Shop G.A.S's SonicAir range in 10L, 23L and Pro sizes, AC Infinity's Cloudforge smart humidifier, and Vivosun's AeroStream with its own humidity probe. Ultrasonic units like SonicAir need their discs replaced periodically — spares are stocked separately.
