A A focused investigation examined vertical farming in indoor stacked growing systems. For the present account of vertical farming, crops grown in stacked indoor layers receive controlled light, water, nutrients and temperature. For vertical farming, this investigation separated the description of the problem from the sequence used to investigate it. B Earlier reports from indoor stacked growing systems used different definitions and observation periods. They established why vertical farming mattered, but the investigation needed compatible measurements and a stated baseline before testing an explanation. C The investigation first defined photosynthetic photon flux as the amount of plant-usable light reaching an area each second. It then collected its main evidence through resource accounting. Research on vertical farming has found that studies measure electricity, water, nutrients, yield, labour and building inputs per unit of edible crop. Observations obtained through resource accounting were checked against background conditions rather than interpreted in isolation. D Next, analysts tested light-use efficiency as the process behind the pattern. Evidence reviewed for vertical farming shows that crop yield depends on how effectively plants convert supplied light into harvestable material. The practical stage focused on local fresh produce. The investigation report on vertical farming then stated one limitation. For the present account of vertical farming, comparisons can be misleading when indoor produce is measured against distant field supply without the same quality and season. The team selected transparent resource audits for the next investigation. E The reported finding about vertical farming remained qualified. One point relevant to vertical farming is that vertical systems can use little land and recirculate water, but lighting and climate control can demand substantial electricity. The discussion of vertical farming notes that operators focus on high-value leafy crops and locate production near stable demand and low-carbon power. Monitoring related to local fresh produce compared later outcomes with the original baseline for vertical farming. The investigation of vertical farming retained weak or unexpected results because they could reveal a limit in the explanation or its implementation. F For future research on vertical farming, transparent resource audits will use common boundaries and report both failures and commercial successes. The authors of the investigation presented this as a targeted way to reduce uncertainty about vertical farming, not as a promise that one result would transfer unchanged to every population or location.
