How many Led lights would I need to fit in a tin can to heat my primary in my fermenting
chamber to 68 degrees in a 45 degree room for 2 weeks?That would depend on whether you put the
series current l...

Well, to look at at in one way, all energy is a type of radiation, it depends on where it is in
the spectrum.The kinetic energy of a speeding bullet is not a form of radiation.The
gravitational potent...

Replace all your bulbs with infrared bulbs and get even more heat! (And a cool new ambiance
too!)If fact you wouldn't. If a device draws 100 watts (not 100 volt-amperes; 100 real watts)
it will delive...

Opening the fridge will warm your house. True!Back in the days when a STU was a half rack of
equipment we put one in a small room that was not tied into the building's HVAC system. When
you turned the...

How's your calculus? a1 is the slope of the curve at pHdi. Draw the line tangent to the curve
at pHdi and extend it till it hits the axes (if you can). The change in mEq per unit change in
pH is a1.Th...

Recommended by whom? There are many that will tell you that stouts should be mashed at the
higher end of the pH range. I don't agree. Are you going to accept my recommendation because I
have a lot of ...

Something is definitely amiss here. Spreadsheets can get screwed up if cells with formulas
aren't protected but the usual result of such is a completely unreasonable answer. I guess you
could try down...

That set of slides is a good place to be looking for fuller understanding of all this.There are
two things going on here that I have glossed over in the previous discussions here. First is
that the ac...

With that said, it will be much appreciated if it were possible for you to explain the
differences in accuracy between the two approaches. When calculating pH measurement by entering
the test mash DI ...

It is usually sufficient (and very important) that you thoroughly rinse off buffers while
calibrating and sample when measuring so that one buffer doesn't contaminate the other, so that
a buffer doesn...
