And as we all know seeds of cannabis will not contribute towards yield. So, at the end of the day the flowers are wasted. In fact, if pollination happens the quality of cannabis decline a lot.

The first method we need to focus on is the cleaning method. Let’s jump into it!

Method 1 of 4:  Disinfecting Plant

Before you start this method you need to take some precautions. Wear hand gloves and surgical masks to keep yourself safe.

You need to create a mixture with Sodium Hypochlorite. Take an empty spray bottle and pour your solution into that.

Now, go to your grow room and start spraying on the surfaces of the room. You can also spray in the plant where you think the pollen might be there. Spray in the air also so that it kills pollen in the air.

After spraying, wait for a while. When you are letting the solution sit, keep the windows and doors of the room closed.

We suggest you do this method in the daytime. The sunlight heats up the solution and lets the pollen remove itself.

The solution will settle in your plant room and simply die. It will also kill all of the pollen. As a bonus, it will also kill viruses, mites, and other substances that are not resistant to it.

Make sure you are cleaning pollen from grow room after you finish this method. Clean up the plants also. Don’t forget to remove pollen sacs hermie.

If this did not work for you, go for the second method.

Cleaning the grow room or grow tent should be your first priority to neutralize the pollen. Removing pollen from the tent and plant areas can help neutralize it.

Follow the following sets of instructions to clean your grow room properly.

First, you need to mop, dust, and vacuum your whole tent area. Make sure the door and windows of your tent are closed when you are doing it. 

You need to ensure that the pollen is not sitting on the rug of the plant room. If you are using an air conditioner to control the temperature make sure you change the HVAC filter.

If it did not help you can try the bleaching method.

Method 3 of 4: Bleaching Plant Room

This method also requires you to take some precautions. We will make chlorine bleach for your grow room.

To create the bleach you need to take a bucket full of water. Now, measure the chlorine and do not add more than 1 quarter to 1 gallon of water. 

Take your time to mix up the chlorine with the water. Wear gloves so that chlorine does not affect your skin. 

Now take an empty bottle of the sprayer. Pour and make the bottle full of chlorine water. 

Now, fix the nozzle of the sprayer to a ‘fan’ shape. We should be cautious about the chlorine we are spraying to the plants.

Spray the solution on the plants and under them. Just one or two sprays are good enough.

If all these seems too much of a hassle, try getting some chlorine bleach from the market.

Now you might ask, does bleach kill pollen? 

Yes, but keep in mind that many plants like cannabis and oak will get brown or yellow if you put too much chlorine. This situation is called ‘chlorine toxicity’. We need to be aware of that. 

If you spray right the pollen on the plant, the grow room will kill itself. And this will neutralize eventually.

Method 4 of 4: UV Light Method

Planting a UV light in your grow room can make a difference you won’t believe. You can get rid of pollen in grow tent just by installing a UV light.

UV bulbs have an effect on pollen. When you are installing a light in the room, the temperature will rise. Rising temperature kills pollen. 

This method is time-consuming but it’s effective. After you turn off the lights, wait for one day to show you the result.

UV bulbs damage the pollen cells. The rising temperature also causes the pollens to kill themselves. UVB is also a pollen killer.

If you are using a UVB make sure not to turn it on for a long time. Turning it on for a long time will make the plants dry. It will lead to crispy buds when you dry this much.

Yes, UVB are scary as they can lead to cancer. They can also damage the plant cells but they are effective in killing pollen.
