Pictures, Sari, we need pictures!
I'd love to see your greenhouse stuffed with plants!
Since you will be growing inside all summer, are you putting in a fan ventilation system? Or does it get some afternoon partial shade in that location? When I visited my Latvian relatives who grow cukes and tomatoes inside all summer, I'm can't remember what they did for ventilation on hotter days, but I suspect it was pretty low tech, cause I don't think they would have wanted to use electricity.
