A good fogging system can deliver a full coverage of bactericide or fungicide on plants which ensures that the foliar and the fruit or vegetables that are being grown receives whatever treatment level that is set. The old greenhouse foggers deliver too much moisture and the droplets are too heavy so that they cannot provide complete coverage of the growing surfaces. There are several reasons that the new foggers are cost effective and more convenient than the old systems. Less maintenance, less downtime and better coverage of humidity and chemicals allows for better growth and production without the hassle of constant repairs.
