Seasons Official Countdown Thread (Now Released)!!!!!!

The glass roof tool is a free patch. I would think its useable without Seasons. that would be without the new Botanist career. So I think the glass roof tool would not be affected by any temperature in your world or the thermostat in the room. I do not know for sure.

I would love to see snow falling in a total glass house. :) I hope we get even more plants.
