Don’t all greenhouses use the sun? Yes, but a solar greenhouse uses the sun’s energy for growing and to provide all of the greenhouse’s heating needs.

The solar greenhouse thermal mass wall has been upgraded with a ‘shiny blanket’.

A double reflective insulation barrier, installed on the inner side of the thermal mass wall, stops warm air from escaping through the wall’s cavity into the field. 

The ‘shiny blanket’, while protecting the greenhouse mild temperatures in the cold winter, gives the thermal mass wall’s cavity the new look of a ‘space ship secret cave.’
