I mean IMO Raspberry Pi cluster are the future. Low power, cheap CPU’s/Ram that are capable of running containerized workloads.

So I am currently switching careers into vertical farming and have done a lot of work and research on this subject and here is just a bit of my 2 cents.

• Vertical farming can be less water intensive then traditional farming. Combined with an aquaculture system it can have negligible to no water loss which is great for arid climates.
• Hydroponic/Aquaponic systems have a huge upfront cost yet a comparably negligible year over year cost.
• This method has proven perfect for growing certain fruits, vegitables and leafy greens however has shown so far that its not the best for growing things like fruiting trees or staple crops like corn/wheat.
• Financing for vertical farms are virtually non-existant. So generally you have to go to private equity for financing. This is a problem as vertical farms are not the most profitable even after recovering $$ from upfront startup costs.

So it has great potential to seriously change our current food system and allow us to keep producing food in spite of drought. However it has a long way to go as a technology and will need serious federal legislation to create financing programs for this method of agriculture so farmers are not saddled with insane debt and growth projections that they will never be able to meet.
