💨 Why VPD Matters – Not Just Temp & Humidity!
Most growers track temperature and humidity…
But if you’re serious about healthy growth, VPD (V***r Pressure Deficit) is the real MVP 🌬️🌡️
It shows how efficiently your plants transpire — that means how they “breathe” and pull nutrients.
✅ Too low VPD? = Slow growth, risk of mold
🔥 Too high? = Plant stress, curling leaves
✅ In the green zone? = Happy roots, strong growth, better yields!
💡 Use a VPD chart (like this one) or app to stay in that sweet spot.
Bonus tip: Adjust lights, airflow, and watering depending on VPD stage (seedling, veg, bloom).
