In Althornin's spreadsheet:

for "% Kill-off Per Day" we have the formula:
=(1-A2^(K5*60*24/I9))*100

If 24 is the number of hours in a day -->and I change it to a 5
--> =(1-A2^(K5*60*5/I9))*100

I still get a result of 99.5763325 effective sterilization in 5 hours.

Al. -Is this correct?

Now I have no idea how often to run this thing. I would definately run it for the first 48 hours, though. And then, what, weekly for a few hours?

I don't want to have to run it unnecessarily...a few extra BTUs, bulb life, etc.
