Reducing transpiration
 

One of the problems I had was that I had difficulty controlling the flow
through the drippers. The valves I was using just did not have fine control.

The flow I was getting was often many gallons per hour. I got hold of some
drip irrigation emitters designed to emit two or three gpm. This way, I hope
to get last transpiration. Consequently, I hope to keep the leaves dryer and
prevent mildew and mold.
