Just like hopbrad said its probably still fermenting but the majority of fermentation is probably over.
If ambient temp was 75-80 then ferment temp was probably 80-85 which could (probably did) cause issues. See how it goes. Use the google search bar at the top and look up swamp coolers. They will help you keep temp down for a more clean/normal fermentation without the investment in a fermentation chamber.
I would buy a gravity reading hydrometer next time you buy supplies. They are only like $6 and will help you with a major piece of the beer making puzzle. Im sure you know but knowing the gravity will tell you lots of things like if beer is done fermenting, if you mashed properly, how sweet/dry the beer will be. That being said you still will be able to make sure you are done fermenting with the hydrometer you have.
