Hay smell & drying too fast

I grew auto's for the 1st time and the plants look great, I plant 1 a month.. my 1st plant dried all the way out in 8 days, lost its stickiness, no smell, just dry. I dry them in my laundry room, which stays at about 55% humidity and 71 degrees f.. I have since bought a small fan for air flow and a small humidifier to push my humidity up but how do I get my Temps down with out running my central ac colder? And how, if possible, can I get the flavor and smell back.. what can I do different with next months harvest?
