73 degrees ambient, is too high for almost any ale as it's the upper limit for most ale strains anyway. Once fermentation starts, it gets even warmer inside the fermenter than the ambient temperature because fermentation itself produces heat.
Can you put the fermenter in a tub of water, and add a frozen water bottle now and then, to try to keep the temperature in the high 60s at the most? It's a challenge in Fl to keep temperatures in the 60s I'm sure.
