## What is PulveCast?

Spray now or wait? PulveCast answers with one colour for every hour — green, yellow or red — checked against the limits of your own equipment, crop and nozzle.

Built for agricultural spray drones, tractor boom sprayers and self-propelled sprayers. Before you fill the tank, see if the weather window is safe and efficient, and which parameter closes it.

WHAT PULVECAST CHECKS, HOUR BY HOUR
• Delta T — the best single indicator of droplet evaporation (ideal 2–8 °C by default)
• Relative humidity and dew point
• Spray drift risk — wind speed crossed with your nozzle's droplet class, Very Fine to Ultra Coarse
• Thermal inversion — forecast temperature at 80 m against 10 m, the classic dawn hazard
• Wind speed, gusts and direction against your equipment's ceiling
• Temperature, rain probability, cloud cover and visibility
• For drones: Kp index and visible GPS, GLONASS, Galileo and BeiDou satellites for RTK accuracy

FREE, NO ADS, NO ACCOUNT
• Spray verdict for the day, with the reason for every yellow or red hour
