Our take on the Greenhouse Sulfur Vaporizer

A sulfur burner that heats elemental sulfur to about 140°C and releases it as a vapor to kill powdery mildew, mites and other pests and fungus in greenhouses and grow rooms. One unit is rated for up to 1,000 square feet, and the thermostat keeps the pan at the target temperature instead of letting sulfur scorch. It weighs 1.6 lb and measures 11 x 11 x 13.5 inches. The best new price is $84.50 at Monster Gardens as of November 6, 2026, with 5 stores selling it new.

What reviewers say

Growers who use sulfur burners like this one report good control of powdery mildew when run on a timer during lights-off, and they value the thermostat over cheap unregulated burners. Complaints center on the smell, sulfur residue and corrosion of metal parts in the room.

What people mention
  • Mildew controlPraisedUsers say regular burns keep powdery mildew from spreading on vegetative plants.
  • ThermostatPraisedThe regulated temperature is seen as better than bare-element burners that scorch sulfur.
  • SmellCriticisedThe sulfur vapor has a sharp odor that lingers and spreads beyond the grow area.
  • CorrosionCriticisedOwners warn that repeated use corrodes metal fixtures and can harm electronics in the room.
  • ResidueMixedSome find a light sulfur film on leaves and surfaces acceptable; others say it builds up.

Questions and answers

How much area does one unit cover?
One unit is rated for up to 1,000 square feet. Larger greenhouses need more than one burner or a longer run schedule.
Is it safe to use during flowering?
No. Sulfur vapor can taint buds and residue is unwelcome near harvest, so most growers run it only in veg or between crops.
Does it need a timer?
The thermostat controls temperature, but you still need an external timer to set burn duration. A timer is not included.
What sulfur should I use?
Use plain elemental sulfur, often sold as wettable or sublimed sulfur. Do not mix in other products.
Is $84.50 a good price?
It is the best new price among the 5 stores listing it as of November 6, 2026. Compare against the other stores before buying if you need faster shipping.
Will it damage my equipment?
Sulfur vapor is corrosive to metal over time. Vent the room after burns and keep electronics covered or out of the space.
Where is the Greenhouse Sulfur Vaporizer cheapest?
At Monster Gardens, for $84.50, as of our latest check.
Where can I buy the Greenhouse Sulfur Vaporizer?
