Greenhouses allow modern growers to uniformly produce large, healthy crops for the market  This is because plants are grown in a climate-controlled structure which maximizes their potential and produces consistent results.  A key to creating the ideal growing environment is controlling humidity.  Often growers use greenhouse foggers, which can produce a fine mist of moisture to cool the air,  However, they can also create excess water which sits on surfaces and becomes a breeding ground for fungus and bacteria.  The ideal fogger produces the right amount of hydration to cool the air, but ensures that it evaporates quickly.  Plants then have the perfect climate to grow.
