I tried leaving on the 5 small fans in my 12 x 12 greenhouse and there seems
to be so far less problems with molds, fungus and mildew so far. And I am
getting alot more spikes than this time last year. Dan

Has anyone got any comments on running a fan in a greenhouse 24/7.Does
this
have any cooling affect costing more to run the heater in winter or just
circulate the air inside the greenhouse?I am running a fan all the time at
the moment,to provided air movement and the atmosphere becoming stagnant
,possibly causing rots/infections etc.As the temps are cooler and humidity
higher.I only have a 10x8 greenhouse.
