Louisiana greenhouse; location?

[moubre13]

I'm putting together a 12ft by 7ft greenhouse at the end of this week, which may end up just as a shade house. It is made from polyethylene. I have been analyzing every area of my yard to figure out where I should place the greenhouse. Keep in mind that summers in Louisiana are brutal and the winters are mostly pretty mild.

I have 3 locations that I have been contemplating:
1) Southeast facing spot that gets sunlight from 7am-1pm
2) South facing spot that gets sun from 8am-4:30pm
3) South facing spot under a Crape Myrtle tree that gets sun from 7am-10am, and 2pm-7pm.

I'm leaning towards location #3 because the tree blocks the hot sun at the hottest part of the day. Half the greenhouse gets more sunlight in the afternoon though but that could be a good thing to have variation for different species. I just have always read that I should put a greenhouse in full sun all day long, but Louisiana is SO hot and I'm not too worried about the winter.

I already ordered 70% shade cloth and 50% aluminet that I will play around with by the way. I don't have a clue what to expect in terms of sunlight in the greenhouse. I am paranoid that everything will burn.

Everything will burn in the summer in a greenhouse without a cooling system in a hot climate. If you shade it enough to prevent burning, there will not be enough light for plants to grow well. Would you leave a dog or cat in there?

Site your greenhouse so it gets maximum light in the winter, and be prepared to cover it with shade cloth even then. Grow your plants in the summer under a cover to prevent rain, if you wish, and provide some shade. The air circulation through open sides will be important to keep plants cool.

I suspect a lot of people there have a plastic roof with Aluminet to keep off rain and sun, and sides of window screening and Aluminet to keep out some of the plentiful bugs.

I really think it will be like being trapped in a hot car. I feel for your needs, the shade-house idea is better.
