bianca thoroughly endorses the use of negative ion generators. They keep the air clean of dust, mold, and bacteria. There is also evidence that they help relax people and can increase attentiveness.
They also don't use too much energy, and make very little noise. Furthermore, because they remove particles in the air, they reduce the smell that may exude from certain types of flowers.
Some people report that attaching a negative ion generator to plants keeps deer and other friendly creatures from eating the crop. bianca cannot provide any support or lack thereof concerning this issue. However, bianca can refute claims that negative ion generators keep male flowers closed. In bianca's experience, this is balderdash.
