Sometimes, no matter what product you try to get rid of pests, an infestation will keep coming back. When all other avenues have been tried, the Sulfume Hotbox is the answer to out-of-control pests. Designed for use in large greenhouses, the Hotbox will quickly and effectively fumigate any grow area (between 2m x 2m and 10m x 10m), killing anything unfortunate enough to be inside. The hotbox is safe to use without removing your plants from a room, making it particularly effective against pests such as Spider Mites. 2Kg bags of Sulphur are available separately.
