Hotbox Sulphur - Replacement Sulphur for Clean-Burning Refill for Ongoing Protection

Running low on sulphur? This refill’s made just for vapourisers like the Hotbox Sulfume, so you know it’ll do the job right. It burns clean and steady – no dodgy fumes, no messy leftovers, just pure vapour where you need it.

If you've already got the unit and just need to top it up, this does the trick. It keeps things ticking over so you can stay ahead of mildew, botrytis, and other greenhouse headaches without skipping a beat.

Simple to use, safe to handle, and trusted by growers who don’t want interruptions in their disease control routine.

Hotbox Sulfume Sulphur Vapouriser – Trusted Sulphur Vapouriser for Greenhouse Disease & Pest Management

When fungal diseases like mildew or botrytis start creeping into your greenhouse, the Hotbox Sulfume steps up. You plug it in, and it just gets on with it – no fuss, no noise – gently filling the space with sulphur vapour that keeps things like black spot in check and makes life a bit less welcoming for unwanted bugs.

The clever bit? It’s how it manages the heat – steady and controlled, without ever overdoing it. Unlike some systems that burn too hot and end up releasing harmful oxides, this one keeps the sulphur at just the right point for clean, effective vapour only.

Despite its compact size, it covers up to 100 square metres and draws just 45 watts – less than most lightbulbs. It runs happily on voltages from 110 to 250V, so you don’t have to worry about setup.

There’s no flame, no combustion, and no faff. Just a neat, reliable unit that does its job properly – safely and quietly – across all kinds of greenhouse crops.
