install a real co2 system, not a home made one. you need high co2 reading to support high heat. I run 88-93* in my sealed room with a 14k btu a/c, 70pint deheuy, and 1200ppm co2 weeks 3-7, 600 wks 1,2,8,9. you'll be lucky to get over 500ppm with a home made co2 kit. ambient co2 is about 380-450ppm naturally, +50-100ppm if you live by freeways or industrial areas.
