What temperature .......

 ... does a Compost Bin/Heap need to operate at to kill weed seeds? Ours is
at 120 degrees at the moment. Hot enough?

Kelvin - frozen to death but things can survive freezing.
Fahrenheit - that is quite warm might kill most things.
Centigrade - pressurised compost bin or just extremely dry?

Putting you 'serious thinking' head on, what would you say?

Well not knowing what angle you where coming from I gave answers for
three of the common units of temperature. Though strictly speaking
kelvin is kelvin not degrees kelvin. Would you have prefered answers
for degrees Rankine or degrees Newton?


Sense of humour failure? If you don't give complete information when
asking a question, how can we be expected give a proper answer?

130F / 55C is usually reckoned as the minimum useful temperature to kill
most nasty stuff off. Need 10 hours at that temperature to cook most
seeds dead. See 'Hot Composting, Accelerated Composting, Thermal
Composting' (http://tinyurl.com/65r8f57 )


But if you succeed in getting to that temperature, you'll probably need
to turn it daily or it will get too hot.
