Heat vs Light Question

I have been thinking about an overall general question about heat vs light. Currently i have a 150w hps flowering 5 ppp plants. Currently the temp. in the room sits around 78. I have the ability to add about 200w of cfls that i used to veg with. But the temp in the room rises to about 86-88 degrees. I have co2 supplementation in the room. The question then becomes in the opinoins of experienced growers, which will produce the most yield, 150w hps ONLY with 78 degree temps, or 150w hps with 200w of additional cfls but will a temp of 85-90 (with co2 supplementation).

Thanks for your opinions

If you have CO2, then you are in luck, my friend. With a CO2 PPM of approximately 1500, your plants will be able to grow at 90-95ºF without stress. However, if for some reason they should start to show signs of heat stress, turn the CO2 up to 2000 PPM and they should do well.

What are you using for a tank for the co2? Im trying to run it in my build but cant seem to get my hands on the huge tanks...

My room is airtight with no exhaust, so I don't use as much CO2 as some people. My tank is the average 20 lb tank. Here's a pic I found on google that looks like mine: http://kevinskorals.com/images/about_tank_careactor.jpg
