New fansThe shelves in my orchid growing window have gotten notably more crowded lately… hmmm wonder how that happened… The four fans on the right side of the window don’t quite manage to push enough air across anymore. There are simply too many orchids in the way. So, this weekend dear husband helped me install four matching fans on the opposite side. The are 140 mm computer fans that push 38,6 CFM (cubic feet per minute – or 66 m³/h) of air but are relatively quiet at 9 dBA. Noise level is of consideration since we actually love to spend time in the room with the orchids.

This picture also shows the strategic location of the humidifier “chimney”. This ingenious invention directs the cold flow from the ultrasonic humidifier up about 2 meters higher in the window where it lets out right behind a fan. This fan is helping to distribute the humid air evenly across the window instead of just leaving a wet puddle around the unit itself… A pretty cool trick for a couple of PVC pipes and some aquarium glue I think.

With these four additional fans I am now running a total of 16 fans in the room. Good thing they are  only 12 volt units…
