More people are considering hydroponic greenhouse farming throughout the USA. This one from Arizona:
Company Purpose: To provide delectable and tasty produce to clients and customers without pesticides and less impact to the environment at a lower price than competitors.
The Problem: Today’s Arizona farming wastes huge amounts of water and land growing crops that are covered in pesticides, can only grow in certain times of the year, and have long shipping times because most of our crops come from California. By the time the produce reaches the customer, it is almost 3 weeks old!
The Idea: Vertical farming inside a warehouse using multiple levels to grow different crops year round. We would use indoor lighting, hydroponics, ventilation, nutrients, and solar panels. Building upwards would let us be able grow different types of crops and many acres of crops on a small amount of real-estate. We would place crops that don’t need a lot of light (like mushrooms) at the bottom of the farm and ones that need more light at the top which would help us conserve energy.
