Exo Terra Monsoon Solo II Misting System PT4200 | Vivarium Humidity

The ET Monsoon Solo II Misting System (PT4200) is a programmable automated misting unit designed for terrariums, vivariums, and greenhouses. It takes the guesswork out of humidity management by delivering a fine, consistent mist on a schedule you set — essential for tropical reptiles, amphibians, and live planted enclosures where stable humidity is non-negotiable.

Pump Performance

A 2.5 BAR (36.25 PSI) pump drives a fine mist capable of reaching all areas of the enclosure. That level of pressure ensures genuine atomisation rather than a weak dribble — the difference between effective humidity and damp substrate.

Programmable Misting Intervals

Duration and frequency of misting cycles are fully adjustable, so you can dial in a schedule that suits your specific species and setup. Whether you need brief daily bursts for a semi-arid species or frequent cycles for a high-humidity rainforest build, the system adapts to your requirements.

Nozzle Flexibility

The unit supports up to two flexible spray nozzles, each of which can be pointed in any direction. This allows precise targeting — whether you want to mist a basking area, a moss wall, or keep moisture away from hides and electrical components.

Reservoir Capacity

A 1.5 litre (0.40 gallon) water reservoir keeps the system running through multiple cycles without constant refilling — practical for keepers who prefer low daily maintenance routines.

For anyone keeping humidity-dependent species or maintaining live planted vivariums, the ET Monsoon Solo II PT4200 provides reliable, hands-off humidity control with the flexibility to suit a wide range of setups.
