The Buzz Around the Legacy

Well Mother Nature gave us a bit of a break in early June, but the time has arrived to turn on the green's fans.  With forecasted highs in the low to mid-90's, nighttime low's in the upper 60's to low 70's, and a noticeable increase in humidity levels, we made the decision to go ahead and turn them on this morning.  The fans help cool the turf, by improving transpiration, which is the process by which the plant cools itself.  The fans improve transpiration by lowering the atmospheric relative humidity.  The lower the humidity the steeper the gradient between the leaf and the atmosphere and the steeper the gradient the faster the plant evaporates moisture to cool itself.  The temperature reduction caused by a fan ranges from up to 15 degrees in front of the fan to around 5 degrees 100 feet from the fan, which has a profound impact on the health of the turf.
