HotBox Sulphur Vaporiser

Quick summary: The HotBox Sulphur Vaporiser is a temperature-regulated sulphur burner designed to control powdery mildew, black spot and other fungal problems. It gently evaporates pure sulphur without burning it, creating a safe sulphurous atmosphere that stops fungal spores from spreading and helps control pests such as spider mites. Sulphur sold separately.

Why Use the HotBox Sulphur Vaporiser?

The HotBox Sulphur Vaporiser (Sulfume) is built for growers who want safe, reliable and consistent sulphur evaporation without the risks that come from overheating or open-flame burners.

• Unique temperature regulation: Keeps sulphur at the exact vapour point--no burning, no sulphur oxides.
• Pure sulphur vapour: Produces clean vapour only, never sulphur dioxide.
• Fire-safe design: The controlled element makes combustion impossible.
• Energy-efficient: Very low power consumption.
• Proven disease protection: Helps prevent powdery mildew, black spot and other fungal issues.
• Pest suppression: Sulphur vapour harms soft-bodied pests such as spider mites.

How the HotBox Sulphur Vaporiser Works

The HotBox uses a thermostatically controlled hotplate that heats sulphur to the exact point where it gently evaporates, rather than burning.

• Sulphur sits in a dish on the regulated hotplate.
• The plate maintains the ideal vapour temperature--no overheating.
• Sulphur slowly evaporates into the room as a fine vapour.
• No toxic combustion products are produced.
• The vapour prevents fungal spores from germinating and spreading.
• Soft-bodied pests are also disrupted by the sulphurous atmosphere.
• The HotBox releases around 2g of sulphur every 8 hours for steady, consistent protection.

How to Use the HotBox Sulphur Vaporiser

Used correctly, the HotBox is a powerful tool for preventing and treating fungal problems in grow rooms and greenhouses.

• Covers up to 100 m²: One unit is typically enough for a standard space of this size.
• Correct hanging position: Suspend centrally, at least 1m below the ceiling for even vapour distribution.
• Fill to the mark: Add sulphur to the indicated level.
• Turn off intake and extraction: Keep ventilation off so vapour remains in the room.
• Use during lights-off: Best applied in the dark period.
• Run for 8 hours: Typically controlled with a timer.
• Preventative use: Once weekly.
• Curative use: Run nightly for up to a week until symptoms improve.

FAQs - HotBox Sulphur Vaporiser

What does the HotBox Sulphur Vaporiser do?

It evaporates pure sulphur into the air, creating a sulphurous atmosphere that prevents powdery mildew, black spot and other fungal diseases from spreading. It also helps control pests like spider mites.

Will the HotBox burn or overheat the sulphur?

No. Its thermostat keeps sulphur at the correct vapour temperature, preventing burning and stopping the formation of harmful sulphur oxides.

How many units do I need?

As a general guide, one HotBox covers up to 100 m². Larger or awkwardly shaped rooms may need more than one for full coverage.

When should I run it?

Use during the dark period, ideally for 8 hours at a time. For prevention, run once weekly. For active issues, run nightly for up to a week.

Do I need to turn off my fans?

Yes. During treatment, switch off both intake and extraction so the vapour stays in the room long enough to work. After treatment, re-activate ventilation and allow safe re-entry.
