Preventing Frost damage by changing Air Humidity
Looking at how some people are protecting their Green Houses against the
frost, i was surprised how tiny the flames were on the paraffin heaters
in the green houses. They were hardly giving off any heat at all.
I was told its not about the 'Heat', but the fact that the flame changes
the 'relative humidity' in the air'.
Could anyone explain fairly simply, how this actually works? Thanks
