World’s largest indoor #farm in #Japan: 100x productivity compared to outdoor fields, uses 99% less water, 40% less power, creates 80% less food waste. No word about CAPEX though - probably not profitable outside of Japan or HK for now. Interesting photosynthesis-specific LED lighting + customized circadian rhythms.
