Greenhouse fan

A much more experienced greenhouse gardener than I, mentioned in conversation the use of a fan to circulate air within the greenhouse. Has anyone got/tried a solar powered fan?

They are for sale around the £30 mark on ebay

 

I think a fan is more important in the winter, stopping the air stagnating, mould developing.etc.

Cant say I've seen the solar powered ones, but then I dobt they would be much use in winter.

 

I suppose its down to the size on the greenhouse and the available ventilation. Dont think you would need one on an 8 x 6, if you have openers on it.

 

You`d need a good sized fan to cool a 100F greenhouse with outside air at 84F. In order of importance, i`d go for passive ventilation, shading, a misting system and then if all else fails add the fan to enhance the misting system :wink:

 

.
I have an electric heater for the wintertime (which I have set to minimum) just in case the temps plummet and the paraffin heaters cannot cope!

It also can be used as a cool fan in summer, it is useless for this purpose as it cannot move enough air!

I have an alu greenhouse, all I do is remove one complete set of 3 panes of glass from one panel, it only takes a couple of minutes to remove them or the same when they have to be replaced when the temps return to normal!

Easier to leave the door or/and windows open. :lollol:
