Nothing wrong with giving a suggestion......just that our attic is a lot hotter than 93 and it took me quite awhile (actually it took X-crispi lol) to make me realize that pulling hot air from the attic instead of cooling the light with intake from household air (which was quickly used up and got hotter) was not helping and was in fact making the issue worse. You're right that his situation could be different.

Ours was that with a 1kw light, central air, AND a window a/c we were not able to keep temps down to below the mid 80's.....unacceptable for optimum growing (remember the leaf surface temps?) in a 10 x 12 room. The answer was to completely seal off
the light source and the heat it threw. We use a cool tube and it works great.

I would lose the mylar and go with flat white paint. Mylar reflects light at approx 95 degrees off itself......flat white reflects the same light at the same distance at 80 degrees. I know. i've done AND TESTED both.

Mylar reflects approx 95% of light back.....flat white paint abou 80-85%. The cool temps are worth the trade off.

It will help....trust me.
