So I want to make a Sasion using the Dupont strain, and I realize I need to pitch at 90* and hold it there, so I bought a brewpad. Well, I apparently did not do my research well enough because this unit has not temp control. Anybody out there using this and have some feedback about the temp it maintains, or better yet how to add temp control for it? I would love to be able to dial in the temp. to a certain degree, plus or minus a bit. Did a little digging on Google and did not have the best luck.
