Yes. But alas, I have no choice. Wifes friends (the church ladies) come over all the time, so indoor flower is out of the question.

During the summer, I do have to stagger the 400w HPS' (12 to 14" or so from tops ) so only one is on at a time. I have it circuted to work like a light mover, light on the left is on for 6 hours, then just before it turns off, the light on the right comes on for 6 hours.
It's usually around 110f outside, and the flower room is ok till that point. Once it get's up to the occational 120f, I raise the lights.
130's outside, and I turn off the lights. Helps that I'm disabled, and am home most of the time.

I also try to plan it so my Swazi Skunk (sativa) is the strain in line for the summer temps, but can't think of a strain I haven't finished in the heat, weather it's sativa, indica or hybrid.
Instead of my usual 3 gallon pots, I flower in 5 gallon pots. Holds moisture a bit longer. Daily waterings up to around 3/4 gal per day per pot. Flushing the ladies is staggered over a week, too. Otherwise humidity skyrockets uncontrollably.
Occational foliar for deficiencies, but keep it to a minimum, and only on the underbranches.

I put an a/c unit in there, and it blows directly over the tops of the plants, and use a 12" fan blowing the cooler air up into the plants. I also have one of those breaker access panels (12" x 12") that is installed tword the top of my 9' tall room. I open it up, and have a dedicated exhaust fan blowing hot air out at all times. The intake is from the a/c.

Alls I can say...it's a dry heat, and I strive to keep it dry. The first year, I misted heavy, and often, thinking they would like it. Burned the tops, and developed mold.
Is it optimal...? No, but it most definatelly works. It can take an extra week or two to finish, but compared to my other options, I'll take it.
Also, active trichome production starts a week or two later than usual, but come finish, they're just fine.:thumbsup:
