Ok - curious if fermentation has started for you yet. Sometimes dry yeast takes a bit of time.
That said, take a gravity reading if you don't see any activity after 3 days.
ALSO - Your fermentation temperature. One thing IMPORTANT to note. The temperature for fermenting is NOT the air temperature in the room. It is the temperature of the beer in the bucket. Get a "Fermometer" if you don't have one already and stick it on your bucket. This will give you a ballpark of the temp inside the bucket.
Fermentation creates heat. So the air temperature can be 70-74 but the beer can be 80+.
Solution: A cooler, water, and plastic 16oz coke bottles w/ frozen water. This is the cooler I use and it is perfect for 1 fermenting bucket. http://tinyurl.com/kwtrdyg
I keep it filled to about 1/2 way up the bucket because I was silly and placed the thermometer too low on the bucket... The higher the waterline on the bucket - the better it will serve to regulate temps.
Ok - so - get back to us when you see activity or take a gravity reading.
