Ideal for medium to large grow rooms and greenhouses. One sulfur burner is capable of treating up to 1000 cu. ft. These are the same type of units used by commercial greenhouse growers all over the world, and it is your best defense against fungus and mildews such as powdery mildew, downey mildew, botrytis (gray mold) and many others.

How it works: The sulfur vapors change the pH on the surface of the plant causing the environment to be unsuitable for fungal growth. The same pH change will significantly slow the reproduction of pests – acting as an effective means of pest control. It is very effective on most flowers and vegetables where powdery mildew and thrips are present.

Features: Heat plate is automatically regulated to ideal vaporizing temperature (140° C); quality construction - aluminum body; safe (outside is not hot to the touch).

Tips on usage: When used indoors, make sure to turn off exhaust fans and lights during operation. For preventative use, turn on the unit for 4-5 hours 2 times per week. For active infestation, turn on the unit 4-5 hours 4 times per week. DO NOT use a sulfur burner around plants that have been sprayed with any type of oil-based products within the last 30 days or the plants will burn. BGH recommends using an Off-Switcher and a 7-Day Digital Timer in conjunction with the Sulfur Vaporizer and your exhaust fans; this will help automate the application and also prevent the fans from coming on during the vaporization period. Automating the application will greatly improve your results, since most people don't have the ability to babysit the system (remembering to plug and unplug the burner and fans, etc.).
