We’re not at the point where it is economically comparable to growing in sunlight, but efficiency improvements are coming!
This looks like the same report from 3 years ago. LEDs have made HUGE improvements since then, with efficiencies over 2.5 umol/j. Would love to see the same report done every few years or so. This study also does not account for utility rebates, which drastically lowers up front cost to commercial growers. Feel free to message me if you want more info on that
