Vapor Pressure Deficit (VPD) is a vital measurement in cannabis cultivation, connecting temperature and humidity to optimize plant transpiration and growth. It guides growers on the atmospheric conditions needed for healthy cannabis development, with different VPD ranges suited to various growth stages—ranging from seedlings to flowering plants. Proper VPD management supports optimal transpiration and nutrient uptake, preventing mold and stress, ultimately leading to robust growth and potent yields, making it an essential tool for maximizing plant potential and yield in cannabis biology and science.
