Sulfur burner for your cannabis grow

The sulfur burner in your cannabis grow can help you prevent many pests, especially fungi.

It is a great ally in mother rooms or grow rooms, because if fungi or mites, such as spider mites, settle in during the growth phase, they can become a major problem from the very beginning of the flowering stage.

Sulfur changes the pH of surfaces, making it difficult for pathogens like powdery mildew and pests like spider mites to take hold, which can be devastating in indoor crops. These pests damage plants and can even ruin genetics kept for years.
So, if the solution is so simple, why does almost no one use it? In many cases, it is because no one has taught them how or they do not fully understand how it works.

How is the sulfur burner used in your cannabis grow?

It is very easy: you just need to install it hanging above the crop, about 2 meters above the ground. You must fill it with sulfur for sublimation, as not all types of sulfur are suitable for this burner.

Then you must connect it to a timer. In this case, it is advisable to use digital timers, as they can be programmed by days.

You should program it so that the burner turns on once the lights go out, runs for two hours, and then turns off, only once a week and with the extraction turned off. We can program it, for example, to turn on every Tuesday, half an hour after the lights go out, run for two hours, and stay off until the following Tuesday.

It is recommended to program it so that the burner turns on once the lights are off, runs for two hours, and then turns off. This process should be done only once a week and with the extraction turned off. For example, you can program it to turn on every Tuesday, half an hour after the lights go out, run for two hours, and not activate again until the following Tuesday.

How to use the sulfur burner in your cannabis grow

This process can be repeated every week in a mother room. However, in growth and flowering rooms, the situation changes, as it must be disconnected once flowering begins.

As a reference, it is advisable to stop using it about 10 days after changing the photoperiod to 12/12, or when you start seeing buds on autoflowering plants.

Precautions when using sulfur in the grow

Sulfur, together with high humidity, can produce sulfuric acid, which can burn plants if they have water droplets or a high density of moist matter, as happens in the buds.

If you see that the plants are yellowing or showing burns, you should stop using it and look for the cause. This usually happens because some growers turn off the extraction at night, which promotes moisture accumulation, the formation of sulfuric acid, and consequently, burns.

They can also yellow significantly if the burner is used too frequently. If you connect it every day, the leaves may suffer because a pH that is too acidic is fixed on their surface and the plant stops feeding correctly.
Once a week is more than enough.

Now that you know how to use a sulfur burner in your cannabis grow, you can consider using it more safely, as it can be a great ally for preventing fungi and pests during the appropriate phases of the crop.
