- hedora 7y agoPulling a shroud over the roof at night is standard practice in passive greenhouses in China. It dramatically reduces heating costs. I’d guess it would reduce lighting costs as well. Anyway, the necessary mechanical systems exist and are produced/deployed at scale. Maybe US regulators should step in and require light / heat shielding at night above a certain size.
