Catching climate drift before it stresses your plants

Many growers only notice their climate has drifted once plants droop from heat, curl in dry air, or show damp patches from high humidity. A clear VPD reading at eye level lets you catch these shifts early and adjust fans, humidifiers or heaters before growth and yield are affected.

How to Use

• Hang or stand the unit at canopy height inside the tent or grow room.
• Keep it away from direct airflow from fans or vents for an accurate reading.
• Check the display regularly and compare the VPD against your grow stage's target range.
• Use the reading to guide manual adjustments to your climate equipment.
