Lucky you, to get a greenhouse to play with! We do need to know where you're located. I'm in NM and my greenhouse goes to about 103 during the summer with all vents and doors open, and fans running. I'm still able to grow lots of nice things. I have tropicals like plumeria and hibiscus, peppers, cilantro, geraniums, air plants and more. Insects are a constant battle. Rodents also like to get in for the free buffet. Even with the problems, I'm loving having it and wish I had more room.
