Indoors on shelves under LEDs. We use fish to feed our plants (aquaponics).
WHY DO WE DO THIS?
Instead of building brand new greenhouses in remote areas, we make use of what is already there. This means we can grow any kind of plant in any place.
HOW IS IT MORE SUSTAINABLE?
Growing plants shouldn't hurt the environment. LEDs use very little energy. We grow up to the ceiling, using every bit of climate controlled space. We use no pesticides, herbicides, or synthetic fertilizers. Our water is constantly cycling and is never wasted.
