Vertical Farming

Short answer: In aeroponics, plant roots hang in the air inside a closed chamber and are sprayed or misted with nutrient solution. Aeroponic towers stack plants up a vertical column, with a pump lifting the solution to the top so it sprays or trickles down over the roots.

NASA worked with AgriHouse on aeroponic research for space crops. A 2006 NASA Spinoff article reported up to 98% less water, 60% less fertilizer and no pesticides compared with soil growing, and yields 45-75% higher. Those figures come from NASA and the company, not independent field trials. Towers like those in the footage do best with leafy greens and herbs. The big catch for indoor vertical farms is energy for lighting and climate control, according to the National Center for Appropriate Technology (NCAT). Several heavily funded companies have struggled: AeroFarms filed for Chapter 11 bankruptcy in 2023, and Bowery Farming shut down in November 2024.

Video transcript: Vertical Farming: Roots in Thin Air

DID YOU KNOW? Aeroponic towers are vertical farming systems that grow plants without soil, instead suspending roots in the air and misting them with nutrient-rich water. This method maximizes oxygen exposure to the roots while delivering precise hydration and nutrition, leading to faster growth and higher yields with minimal water use compared to traditional agriculture. NOW YOU KNOW!

The write-up

Roots in thin air. Tower farms mist or trickle nutrients over bare roots.

  1. Exhibit A

    How it works

    Aeroponic systems suspend bare roots in air and spray or mist them with nutrient solution. Towers do this up a vertical column fed by a pump.

  2. Exhibit B

    The NASA connection

    NASA worked with AgriHouse on aeroponics for growing crops in space. NASA Spinoff reported big savings in water and fertilizer.

  3. Exhibit C

    The claimed numbers

    Spinoff cited up to 98% less water, 60% less fertilizer, no pesticides and yields 45-75% higher. These are NASA and company figures, not independent trials.

  4. Exhibit D

    What grows well

    Towers are best suited to leafy greens and herbs. Hydroponics handles a wider range of crops.

  5. Exhibit E

    The energy problem

    Energy for lighting and climate control is indoor vertical farming's biggest cost. AeroFarms entered Chapter 11 in 2023, and Bowery shut down in 2024.
