greenhouse humidity

anyone got any views on humidity levels ideal for naners in a greenhouse?

I'm just planning on a humidity control system. I've got the humidistat and solenoid valve setup sorted. I just need to figure on a fogger/misting setup. also any idea of how humidity settings should vary between summer and winter?
I'm looking at using this sort of thing:

This should help in planning ours.

Thanks for asking!

Re: greenhouse humidity

As humidity is caused by moisture in the air its obviously going to depend on where you are in the world and the time of the year. Having said that the global warming thing seems to be changing the picture rapidly.

Here is a link to an interesting article on the Uk changes

This map is also good for getting 24hr forcasts

weather.co.uk - UK - Relative Humidity Fcst (24 hr)

Normal room humidity is in the range of 40 to 70Rh so i think i would aim for >70 to 90Rh in summer noting that instrument accuracy may well only be within 5% anyway.
