Climate, Cold & Container GrowingIs a greenhouse circulation fan equivalent to opening vents around mango trees?
A circulation fan moves air within the structure; opening vents permits exchange with outside air. Consider which problem needs attention before treating the two as interchangeable. Interior movement may help reduce stagnant pockets, while excessive daytime heat can require controlled ventilation. Check actual canopy conditions and avoid a concentrated cold draft across plants. Adjust the system as a whole, since moving warm humid air around a closed greenhouse does not necessarily remove that heat or moisture.
