Greenhouses are early adopters of automation. But they only automate the stuff that actually works reliably. This means watering schedule, fertilizer and light.

Greenhouses are early adopters of automation. But they only automate the stuff that actually works reliably. This means watering schedule, fertilizer and light. There are few things mechanical that can go wrong with them, especially the light part. They don't have a hord of maintenance people that have time to fix everything that goes wrong. They might have one person that is doing that beside other things. I live close to one of the bigger ones in north Sweden. They run some accelerated daytime schedule in the darkess of the polar winter so at least part of the nights has a yellow sky in the whole area. You see it for 10 km on the way to the village nighttime. Could almost believe it's a 100 k town but no :-)
