Shield Sulphur Refill

SHIELD SULPHUR REFILL for the  Shield Sulphur Vaporiser is a great way of combating black & grey mould, powdery mildew, mites and other common problems for greenhouse and indoor plants. It works by melting and vaporising pure sulphur granules at the perfect temperature.

The sulphur exchanges into the air where it redistributes over the surface of the leaves/flowers forming an invisible plant shield.  Mould spores die upon immediate contact and pests must relocate or suffer the consequences.


  • At the onset of the flowering period. Stop two weeks before harvest.
  • Treats up to a 20x20m² area.
  • Use every third day for 1 hour during late evening or lights off period.
  • If tip burn occurs, reduce by 5-10 minute intervals until burn stops.


The Shield Sulphur Vaporiser heats the sulphur on a thermostatically controlled hot-plate.  The vapouriser heats the sulphur just to the point where it vaporises slowly into the grow-room.

With it’s carefully controlled heating action, the vapouriser will not produce any toxic combustion products like sulphur dioxide, only sulphur vapour is produced. Sulphur vapour kills mould spores, preventing the spread of fungi and rot.  Sulphur is also toxic to spider mites and various other grow-room pests.  The Vapouriser releases a consistent dose of sulphur over an 8 hour period ensuring there is no wastage.

A single Shield Sulphur Vaporiser can be used to treat a grow-room up to 100 m2 in size.  The Vapouriser should be hung roughly in the centre of the grow-room at a height of least 1 meter below the ceiling to give the sulphur vapour enough space to dissipate properly. The sulphur container inside the Vapouriser should be filled to the fill-level mark with sulphur and then placed onto the internal hot-plate.

During treatment times it is necessary to have grow-room extraction and intake fans switched off so that the sulphur remains in the room to do its job. This means that the best time to use the Vapouriser is during the dark-period. Treatments take 8 hours and a timer can be used to switch the Vapouriser on and off. As a preventative measure, the Vapouriser should then be used once a week. To help eradicate an on-going infestation, the Vapouriser can be used as frequently as necessary, even every dark-period for a week or so until the situation is under control.
