How to dry my AE 100% cotton cargoes?

well i have these 100% cotton cargoes and they say tumble dry low on the inner tag, and i don't want them to shrink, and my dryer doesn't have that as an option, it only has (more dry, less dry, high heat, low heat and more also fluff air but that takes to long and i really don' t want to let it dry on a hanger in the house because of the wrinkles and it can't be ironed plus my house is temporarily hot full of humidity, so what can i do to avoid shrinkage? please help.
