Controlling the humidity of your growing space matters as much as light and nutrients. The BloomLED 5-Head Mist Maker produces a fine ultrasonic fog to keep humidity at its ideal level, from cloning to flowering.

Designed by BloomLED, a French indoor-growing expert for over 10 years, this fogger relies on ultrasonic technology: five piezoelectric membranes vibrate at high frequency to turn water into an extremely fine cold mist. The result is a dense fog that saturates the air with moisture without soaking your substrate or leaves, perfect for grow rooms, greenhouses and large grow tents.
With five heads, this model delivers far more vapour output than the 1- or 3-head versions, making it the choice for large volumes and demanding setups. It fits perfectly into an automated system: paired with a humidistat, it triggers misting as soon as humidity drops below your set point, for a stable atmosphere day and night.

Ultrasound breaks water into micro-droplets that disperse instantly into the air, without wetting foliage or electrical equipment.
Keep the optimal humidity for each stage: high for cloning and vegetative growth, more moderate during flowering.
Ultrasonic technology barely heats the water, offering far better energy efficiency than warm-steam humidifiers.
The Mist Maker runs quietly, without disturbing your living space or your crop.
A saturated atmosphere promotes rooting of cuttings and limits water stress on young plants.
Combine it with a humidistat and a timer to fully automate your humidity management.
For lasting performance, use clean water (ideally reverse-osmosis or demineralised) to protect the membranes, and clean the cells regularly. Keep a sufficient water level and favour cyclic operation to avoid over-saturating your space.
Thanks to its five cells, it suits large grow tents, grow rooms and greenhouses that need a strong moisture supply. For small spaces, the 1- or 3-head Mist Maker is more appropriate.
What water should I use in the fogger?Use reverse-osmosis or demineralised water. Hard, calcareous water scales the piezoelectric membranes and shortens the unit's lifespan.
Can the fogger run continuously?Cyclic operation (for example 15 minutes ON / 15 minutes OFF) is recommended to avoid excess humidity and protect the membranes. A timer or humidistat automates this cycle.
How do I regulate humidity automatically?Plug the Mist Maker into a humidistat: it starts misting as soon as humidity falls below your set point and stops once the value is reached.
Could the fog damage my plants or equipment?No: it is a very fine cold fog. Simply ensure good air circulation and avoid aiming the output directly at electronics or close foliage.
The BloomLED 5-Head Mist Maker guarantees stable, professional humidity for vigorous plants, from the first cutting to harvest.
