Thanks. I am the original author of the question. It is a vertical farming business within a shipping container. My husband is an electrician so we want to build a plug and play indoor farm that uses the absolute minimum of electricity and is partly self powered. For leafy greens or medicinal cannabis growth. We need about $30K to build the first one. I want to create something so people can buy a ready to go business, complete with SOPs etc. I say ‘about’ because I had priced it very carefully and then the world changed! Thanks for the tips.
