AC Infinity VPD Thermometer The AC Infinity VPD Thermometer is a portable VPD meter designed to accurately measure Vapour Pressure Deficit (VPD), temperature, and humidity in grow tents, grow rooms, and indoor growing environments. Built specifically for indoor cultivation, it helps growers monitor environmental conditions and optimise plant health throughout every stage of the grow cycle. Maintaining the correct VPD is essential for healthy transpiration, efficient nutrient uptake, and vigorous plant growth. While temperature and humidity are often monitored separately, it is their relationship that determines how effectively plants absorb water and nutrients. When VPD falls outside the ideal range, plants can experience stress, slower growth, dehydration, or reduced nutrient availability. The AC Infinity VPD Thermometer provides accurate, real-time environmental readings, allowing growers to quickly identify issues and make informed adjustments to ventilation, humidification, heating, or extraction systems. Its handheld design makes it easy to measure environmental conditions throughout the grow space. Check multiple locations within the canopy, identify humidity pockets, detect temperature hotspots, monitor propagation areas, or assess airflow around LED grow lights and ventilation equipment. This helps reveal hidden climate variations that fixed sensors may miss. The clear digital display shows: Vapour Pressure Deficit (VPD) Temperature Relative humidity By regularly monitoring environmental conditions, growers can improve climate stability, encourage healthy transpiration, support stronger vegetative and flowering growth, and reduce the risk of plant stress, mould, and mildew. Compact, lightweight, and easy to use, the AC Infinity VPD Thermometer is ideal for hobby growers and professional cultivators alike. Whether you're managing a small grow tent, propagation area, or larger hydroponic grow room, it provides a fast and reliable way to optimise your indoor growing environment.
