The probe reads the true temperature of your space and lets the GSE controller adjust extractor speed continuously, venting excess heat before it stresses your plants.
A generous length to place the sensor at canopy height, away from the controller, for a reading that reflects what your plants actually experience.
Compatible with GSE controllers, the probe connects with no complex setup: perfect as a replacement for a faulty probe or as a reliable spare.
This 4 m probe is designed for GSE fan-speed and temperature controllers. Check your controller connector; if unsure, the BloomLED team is happy to guide you.
Where should I place the probe?Set it at canopy height, shielded from the direct extractor airflow and lamp heat, so it reads the temperature your plants truly feel.
A dependable probe means a controlled climate: avoid the heat spikes that stress your plants and protect every harvest with a spare sensor always on hand.
