John Dole and Brian Whipker showed off NC State’s Research greenhouses. The current research is on nutrient disorders, using automated sump pumps and controllers.This experiment uses 60 percent less labor and the fertilizers used in the experiment were cut in half.
The media is a silica sand that is prewashed.
This crop is gloxinia, but the same research has been done on poinsettias, gerberas, cyclamen and will include cineraria.
