Re: [nafex] Re: chilling hours
It would be pretty easy for a computer to read and respond to a digital

rainfall by computer. Why not? You could even write a program for your
walk-in cooler that would perform the chilling hour requirements tapering
up at either end. Know what I mean?

>> 1 hour below 34 degrees F =0.0 chill unit
>> 1 hour 35-36 degrees F =0.5 chill units
>> 1 hour 37-48 degrees F =1.0 chill units
>> 1 hour 49-54 degrees F =0.5 chill units
>> 1 hour 55-60 degrees F =0.0 chill units
>> 1 hour 61-65 degrees F =-0.5 chill units
>> 1 hour >65 degrees F =-1.0 chill units
>>Hope this helps to calculate chilling hours.
