Why sustainable growing?
Less water
Aquaponic and hydroponic systems recirculate water instead of letting it drain away, so they use much less than watering soil.
Year-round growing
Indoor systems allow you to grow fresh produce regardless of climate or season.
Fewer pests
Indoor and covered systems keep many pests out, so you can often grow without chemical sprays.
More from less space
Stacked and vertical setups fit more plants into each square foot, and leafy greens often grow quickly in a well-run system.
