This advice only applies to ales. I defer to the more experience brewers on the board for a lager, but I live in steaming hot florida and it gets to at least 80 during the day even with the A/C on. One thing I found made a BIG difference was NOT using the yeast that came with the kit (although it will work), but spending the extra two bucks and getting better yeast. I've been using the dry Safale products with good results (again, too hot to buy liquid yeast, although I would like to try it). And when the package says dry pitch without a starter, you can rely on that, it works just fine and very quickly.
