Vertical Farming: Can Sunlight Be Sustainably Replaced?

by Natalie Knops

An emerging trend in agriculture, vertical farming, has been developing across the United States. Vertical farms, a new form of green urban architecture, are controlled, indoor environments that regulate lighting, nutrients and weather. These farms are typically set up in hydroponic towers that often inhabit urban buildings (Frazier, 2017). Many are optimistic about the benefits of this practice: fast production, minimization of land use, water conservation, minimization of fertilizer/agricultural run-off, and most significantly – the drastic reduction of transport emissions. Although the concept of vertical farming is increasing in popularity, some are skeptical about the drawbacks of this method due to the fact that retro-fitting buildings for indoor plant cultivation is capital-intensive and energy costs run high. Vertical farming requires specialized LED lights that generate photosynthesis. Continue reading
