China: Chengdu vertical farm takes agriculture to new heights In an 8.8-meter-tall automated plant factory in Chengdu, Sichuan province, rows of lettuce bathe in red light on 20-layer cultivation racks and grow at twice the normal rate. The vertical farm facility, covering just 100 square meters, was developed by the Institute of Urban Agriculture of the Chinese Academy of Agricultural Sciences.
"The factory enables full control over light, temperature, water, nutrients and air. Shi said the growth cycle for lettuce here is only 30 to 35 days — half the time needed in traditional open-field farming — while yield per unit area can reach up to 120 times that of conventional methods.
Why this matters: This matters when it gives operators a clearer way to manage water, nutrients, and root-zone risk. That kind of control usually improves both resource efficiency and crop consistency.
Frequently Asked Questions
What should growers evaluate before changing a lighting strategy?
They should look at crop type, canopy structure, current light distribution, energy cost, expected yield gain, and whether the new strategy improves whole-canopy efficiency.
Why is light distribution often as important as light quantity?
Because adding more photons to already saturated leaves does less work than improving how light reaches the parts of the canopy that are still underperforming.
