Humidity / Heat Issue

Hey Family, I just bought a dehumidifier to put in my flowering room and I'm getting the humidity down but now my temp is rising up to 84 deg F, So I put some duct over the Air Outlet Grill to vent the heat it was giving off to the outside, this is also tied into my venting for my 600 HPS Air Cooled Reflector, well a 6" Inline Fan or 6" Blower bring the temp's down, or do I need to put a small A/C unit in my 6'x4'x6.5' flowering room Thanks for the help....

ehehehe check out the temps they grow in i dont belive the temp would really bother the plant unless it was over 100 as they grow in jamaica and its hotter over there and other places like that.check it out i maybe wrong but mines has been at 90 and my plants are just fine and dandy
