Dont stand near me in a coming storm I have been tickled by God! And thank God not scorched by the lightning devil!! If you see my hair starting to go up RUN! Ye-ouch! I actually did have some slight burns once much like a over backed sun burn to which was not fun, but peeled and had a blister!, LOL! But gads.. I have had near misses of nearly a dozen times just because I work outside a lot! But the power from an outlet, that can kill you too So no inner outlet, and no inner fuss~!
So now, getting back a bit to the outside of the structure.... here is the veiw of the north wall of my greenhouse. Yuu will notice it has only 2 vents on the roof. Those vents pop open with the solar openers and the sun can enter their openings. You want to locate your greenhouse to that advantage. The sun heats those thingees that look like a shock absorber, the temperature in them rises and pushes teh cylinder to pop the vent open. Occassionally those openers wear out and do need replacing. I think we did ours once.
I am fortunate I have a security light above my greenhouse. It runs all night and so well it affords a little extra light hours for my plants, but I cannot really say it makes that big of a difference on their growth, just is nice to work in the thing at night if I choose to when it is dark!
