New Addition This Year (late in the season) S-Burner
This year experimenting with a Sulfur Vaporizer to help control Powdery Mildew. Sulfur is the most effective spray product for powdery mildew and a vaporizer is a very efficient use of the product when the growing area is enclosed. With the plant growing this year there seems to be some natural resistance/tolerance. However, the use of a sulfur vaporizer may have some benefits for disease control.
There are concerns with the actual vapor which should be avoided by growers and this can only be applied at times of lights off. Making sure the unit gets hot enough, and using a timer can make the implementation of this control method easy to implement.
The image shows the red burner that has a 100-watt ceramic heat bulb in it which will take the 99.9% High Purity Sulfur Prill pellets and turn them into a liquid that a small portion will vaporize off from. A metal protective bowl has been added above and below the burner to catch any potential liquid sulfur that may splash out during the heating process. The hope is by the morning the container that contains the sulfur will look like it does in the upper right-hand image. When this is seen, this demonstrates the solidification of the sulfur after the liquidation and vaporization process. It seems the sulfur can start out as brown in the early morning and then progress to its more traditional yellow coloration.
Remember, the sulfur fumes are hazardous so setting the unit on a time and only entering after the unit has had a chance to cool down and the area is vented is important to keep in-mind. The usage is open to some grower preferences, but running it for 5 hours (10pm-3am) for about 8 continual days is a good starting point. Note: Make sure not to apply any oils to the leaf surface as this will have a negative interaction and start with minimal durations and watch for signs of plant damage.
