My greenhouse faces North West, so the right front corner faces North. Half of that is blocked by a structure added on to make a laundry room. So the North only shines on half of my greenhouse. The back, or South East is blocked by the house itself. So the sun never shines directly on that part. The South West backs up to the back of the house so it never gets any direct sun. And the left side of the greenhouse faces West. So the only direct sun comes from above and on the West and North West walls. I hope this makes sense. I tried to draw it using PSP but I'm not good enough at that yet. I hope this makes sense.

What I am concerned about is the fan being too stong for the size of the greenhouse. I don't want it too cool in there. What do you all think? Also, he is a photo of the fan in the greenhouse. It is cool today so we don't really need it.
