yeah it is in the attic so that is definitely a concern but i have a wind propelled 12 inch fan directly above them in the roof so i get a good constant flow of fresh air with the help of 2 oscillating fans, i have been recording the temps daily in preparation to make sure the range is good and it goes from about lowest of 68 at night to about 85 in the daytime, luckily i live right near the beach so a good wind is never far away : )
