- zdragnar 7y agoThat is insanely expensive compared to the more standard poly that gets used, and something as simple as a hail storm night shatter the glass and ruin an entire crop. I imagine some cheap opaque sheet metal, solar panels and 24/7 artificial lighting would be cheaper than mega-greenhouse amounts of specialty glass.
