After further testing, this only reduced the temp in the greenhouse by about 10-15 degrees, still not enough, so the next step was to cut two openings in the north facing wall to allow for more airflow across the greenhouse. These openings were turned into shutters rather than windows for protection against northern winter winds and will be insulated as time permits, both openings were cut out to approximately 2ft x 4ft, for another 16 sq ft of ventilation. This dropped the inside temp to the ambient outside temp when all ventilation was opened. I also fitted barrel bolts to all openings in order to secure them when closed....here is a pic of the north side of the greenhouse.

House screening was placed on all openings for pest control. Next I was off to run the electric to the building, this of course took me a couple of days to complete.I have 4 -110v 20A outlets, three inside the building and one outside the building as shown above and below.

I also had to dig an 8inch deep 60ft trench and place 12-2 UGF wiring to the building which took the longest...especially in the 100+ degree heat...whew!!! was it hot. Next came the water line, where I dug a 2ft deep trench 35ft to the house in order to tie into the backyard faucet. I placed 3 hose bibbs inside the the greenhouse for convenience with two being on stand pipes (see photo above) and the third being at ground level so I can drain the water out of the system when needed for repair or due to freezing temps in the winter.
Well, thats pretty much it for this post...now that the greenhouse is complete I can move on to the next phase building my aeroponics/aquaponics systems...more on that in the next post.
