RAM Ultrasonic Humidifier — 5L Tank

RAM Ultrasonic Humidifier — 5L Tank Grow-Room Humidifier

A grow-room-specific humidifier with a generous 5L tank — ultrasonic technology produces fine cool mist without heat, keeping your grow space humidity where propagation and vegetative plants need it (70-80% RH). Much cheaper to run than domestic humidifiers, and sized properly for the run times a tent or small grow room demands.

Why growers choose the RAM 5L Humidifier:

• 5L tank capacity — runs for extended periods between refills, bigger than most domestic humidifiers
• Ultrasonic mist generation — fine cool mist, no heat, no plant damage
• Designed for grow-room conditions — built for continuous-operation duty, not occasional use
• Essential for propagation — 70-80% RH is critical for cuttings to root reliably
• Supports vegetative humidity — 60-70% RH during veg improves growth rates and leaf development
• Quiet ultrasonic operation — no fan noise, just fine mist output
• Pairs with G.A.S Intelligent Humidity Controller — for proper automated humidity management

Who it's not for:

For larger grow rooms (2m+ tents or multi-tent setups), the SonicAir Pro from G.A.S has more output. Use filtered or RO water to prevent white mineral dust from depositing on plants and equipment. In flowering, reduce humidity to 40-50% to prevent bud rot — this humidifier is most useful in veg and propagation stages.
