When I use in spring electrict bottom heating , day temp +17C is a limit when bees start to ventilate extra heat away. Then by night temp may be +5C.I'm wondering when is the best time to remove this now it's geting warmer?
In the hive temp is something over 30C. Outside you have at night 10-15C.Top insulation for winter - yes,yes,yes.
Top insulation for summer - why?
The average temperature in 'Central England' is around 9deg C, given that a bee can often become immobile at anything less than 15 deg C its a wonder any bees can exist over here. It's only flying that keeps them warm enough to fly.When I use in spring electrict bottom heating , day temp +17C is a limit when bees start to ventilate extra heat away. Then by night temp may be +5C.
I shoud put a timer that heaters are on only at night.
As far as I see you day temps are hardly 10C. Sometimes higher but not much and not long time.
Bees reguate themself the hive.Finman,
But what I was trying to counter was the need to keep the hive cool.
