You can certainly grow hops in FL! I have Cascade, Willamette, Chinook, and Nugget all growing. We've already gotten the first Harvest from the Chinook, and Hops are starting to grow on Willamette and Nugget. The Cascade are growing a little slower, but are at least 2-3 feet tall. The days are only shorter by 40 minutes or so in the far south (compared to far North). Hops need about 8 hours of full sunlight, and summer days in the continental US are 13-14 hours. Give it a shot, and good luck!
