Sun heats up greenhouse, but glass has a high thermal transmission, so heat will escape from the glass if there is a temperature differential. | |

| Nov 12, 2020 at 0:48 | comment | added | fred_dot_u | The quoted portion regarding "perfectly insulated container" is unrealistic. The level of insulation and heat retention is related to how much money one wishes to throw at a project. Aerogel walls (transparent and high insulating) would be astronomically priced, just as an example. Black surface metal means no light passes. How would the plants feel about that aspect? If sunlight is not part of the program, it's not a green house. | |
