The Hotbox Sulfume sulphur vapouriser helps to protect crops from fungal diseases such as Mildew, Botrytis and Black Spot. It also inhibits the spread of greenhouse pests. The Hotbox Sulfume sulphur evaporator has set the standard so high that the word ’Sulfume’ has become an eponym for all sulphur evaporators. Do not be fooled - all sulphur evaporators are not Hotbox Sulfume’s. The Hotbox Sulfume vaporises less than 1 gram of sulphur per hour.
