PulveCast: Spray Weather

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.
