MetroGrow Hawaii is utilizing various state of the art technologies to produce the highest quality produce possible with a focus on food safety and resource management.

Aeroponics - A type of hydroponic growing where the plants roots are exposed to air and then periodically sprayed with nutrient solution.  Compared to traditional growing or other hydroponic methods, aeroponics provides plenty of oxygen to support root development, uses less water and nutrients, uses no growing medium that needs to be cleaned or replenished and can support faster crop maturity.  MetroGrow Hawaii is testing both rotary atomizers and high pressure hydraulic nozzles in its aeroponic systems.

LED lighting - Indoor hydroponic operations have traditionally used high wattage lighting that produced a lot of heat and used a tremendous amount of electricity.  Advances in LED technology have enabled the indoor grower to reduce both heat and electricity use while maintaining adequate light to support plant growth.

Root zone cooling - Producing plants normally grown in temperate climates is often challenging in most parts of Hawaii.  Research in other tropical climates has shown that cooling the root zone of the plant, usually by cooling the nutrient solution provided, can allow optimal temperate plant growth even with high air temperatures.  MetroGrow Hawaii is utilizing this strategy to produce normally cool weather crops all year round.
