need some input about a hoop house

[imagineink]

im planing on building a hoop house in early spring approx 8x10ft and close to 8ft high with two vents on opp sides in the front and back corners close to the highest point in the roof, and open about 5inches all the way around at the base hopeing that this will allow good air flow. the thing im worried about the most is having all my plants in there when it gets 90*-100*f and above and lots of times little to no wind come late summer. the humidity in the summer is 80-100%. so im affraid that the plants will cook in the hoop house at those times.if i could have fans i wouldnt be quite so worried but i cant have power cause there is no power source(we live in a really old little house that really needs to be rewired...BAD)
they where all on the front porch last year but between wind,storms, and the dogs they were constantly getting knocked over and uprooted.which is amazing i had any blooms at all!
the cool growers might have to stay in the house(no ac either)

what do you guys think good idea or bad idea
ps: at least it will be under a big maple tree that will give some shade at hottest part of the day and some shade cloth to help with the rest

i dont even know if i put this thread in the right spot...mmmmaybe

when I had my greenhouse in charlotte, and it had 4 vents in the roof, even with them open the heat build-up is extraordinary even with fans. I did not have a cooling system.

What I did was move the plants outside in the summer, and used the greenhouse for fall and winter.

For example, even on a winter day, when the outside temps were in the 50s, the greenhouse, with fans and 4 roof vents would easily get mid to high 80s if it was a bright sunny day. During the summer, with vents open and door wide open it was unbearable in there.

If you are planning on using it just for summer (which I assume since you are not building down to the ground), what about the same structure, but using shadecloth as your walls. Would keep the dogs out and help a little bit with containing them.

You could also use different kinds of shadecloth, allowing for different light intensities inside.

thanks that definitely helps i think im a little closer to a better plan and when summer comes around i think i might just take them back to the porch and set them in some wooden plant boxes or something so they cant get knocked over. i think i will go ahead and have the hoop house closed on the ground cause i like the idea of having them outside longer in the other seasons.

it just a big experiment really and see how it does, again thank you
