I think we should promote hydroponic farming green houses to compete with the high productivity of the south. Some crops like tomatoes grow twice as fast in hydroponics.It would always be cheaper and better quality when grown in ur region. Paying drivers, truck owners , taxes from various regions and it takes days to deliver compared to fresh stuff delivered straight to the market from the farm. We now know PL can grow stuff, the next step is promote farming and leave unsustainable nomadic lifestyle.
Overall hydroponic plant can grow up to 30-50% faster than a soil plant. Then we can raise taxes on the vegetables coming from the south to give our local farmers a heads up.
