Profile
While tinkering with some custom made sensors for my greenhouse back in 2020, I stumbled upon the VPD idea of monitoring crops in controlled environments. This is pretty popular among cannabis growers. A lot of them used PDF or printed charts for calculating the VPD value based on air/canopy temperature and air relative humidity. Why wasn't there any decent tool for this? I coded one in December 2020, registered a domain and rolled it out before NYE.
