Temperature & Humidity
Temperature tells you how warm or cool the air is. Relative humidity tells you how much moisture is in the air. Read them together to understand whether conditions are hot, cool, dry, or humid.

HOW TO READ THE THREE GRAPHS
A quick guide for gardeners
Air VPD — Vapor Pressure Deficit
VPD is a simple way to describe how strongly the air can pull moisture from plants. A higher value means drier air and potentially faster water loss; a lower value means more humid air. Here it is calculated from air temperature and relative humidity, not leaf temperature.
PPFD & DLI
PPFD: Photosynthetic Photon Flux Density
DLI: Daily Light Integral
PPFD shows how strong the plant-usable light is at a particular moment. DLI adds that light up across the day, so it is a simple way to compare the total light received from one day to another.
You do not need to be a climate expert to use these graphs.
