Melissa, I use Aluminet even in my empty greenhouse over the Summer, the greenhouse would otherwise heat up the house as it is part of it. I always install the Aluminet on the inside of the greenhouse, and it brings down the temperature ca 10 -15 degr. , it makes a big difference.
Happily my Habenaria medusa starts opening.
And Habenaria rhodocheila still look pretty
edited to correct - this is Habenaria erichmichaelii, not rhodocheila and it should be fragrant
