Outside...in texas

So my plan isn't fully outdoor more mix of outdoor/greenhouse?
I have a small wooden closet about 5'x4'x7 off the side of my shop the top 3 inches is screened(for some reason)
Anyways I already ripped the plywood roof off and pretty much wondering g if I can grow in there... It will be hot as hell but maybe with a fan and and an exhaust fan I can keep a high heat strain in there
Sorry to sound like a noob I'm indoor only....
Basically I've checked and it gets about 5 hrs of sunlight and I'm thinking of rmoving one of the walls and replacing with poly
Maybe a whitewashed? Glazed? Plexi? Idk just kinda tossin ideas around
There's a hole...(was used a doghouse)near bottom I thought maybe an exhaust fan (filter) placed here would help with stealth and heat and get an oscilating fan bc there will be little air circulation with only roof open
Anyways can anyone help with ideas or suggestions? Maybe some links to open roof shed grows I'm sure there's something out there

Try and exaughst some heat and throw a thermometer in there and see what the temps are it can work as long as they don't fry mabey throw a shade cloth over too to help a little
