I leave mine in my garage where the temps usually stay in the mid 70's all summer except on the hottest days ( 95+ fahrenheit outside ambient temp ) where it reaches the mid 80's. My tops fit loosely so I sprinkle some diatomaceous earth around the lip and then cover with the lid and put a brick...
Just a quick observation from the pics, if possible try to get all of your electrical equipment off of the floor, you never know when a pump will fail or a line comes loose. I am looking forward to watching this grow. Good luck.
