The Hotbox provides effective control of powdery mildew, black spot and botrytis in an area up to 328 sqft. by vaporizing granulated sulfur (available separately). When used correctly, the burner safely heats sulfur to the optimum temperature for vaporization, without producing other unusable waste compounds. Easy to use, gardeners simply hang it near a 120-volt outlet, add granulated sulfur and plug it in. Customers should follow all instructions for safe use.
