How to control odor in a Cannabis grow room

In spite of their relative ease of management, Cannabis grow rooms are sometimes plagued by a number of problems. Perhaps the most ubiquitous of these is odor. Odor from the Cannabis grow room may result form a number of cultivation procedures. The first is usually the use of compost manure. For new farmers, sometimes they opt to use compost manure in place of commercial fertilizers. While this is a good move, it often comes with its own challenges. There are a number of reasons why compost manure is used.


The first reason is that it is cheap. Initial costs in setting up a grow room may sometimes become so prohibitive that novice farmers use this chance to cut on costs where possible. By using compost manure, the cost of buying fertilizers is drastically reduced. Secondly, some farmers use compost manure for the production of Carbon dioxide (CO2). CO2 is the gas that Cannabis plants use, with the production of oxygen (O2) in return. The use of compost manure to meet these needs occurs when bacteria breakdown the decomposing matter. As a result of the decomposition process, a lot of odor is produced. This not only makes the use of compost unhygienic, it also makes gardening quite a difficult task.

This creates the need to find methods which will help control this odor, if not completely eliminate it. There are several methods to get this done, all with different success rates.

  • The first method is to find alternative sources of fertilizers. One option is to use commercial fertilizers. Despite the initial cost, this is the only permanent solution to eradicating the smell completely. Fertilizers are available at online vendors; just make sure you shop wisely.
  • The second option is the use of charcoal filtration. The charcoal particles absorb the smell, and are usually discarded after some time; otherwise they fail to serve their purpose. After deodorizing with the charcoal, you may use an ionizer to get rid of any remaining odor.
  • There are several brands of ozone generators available. The generators work by absorbing the odor molecules. When used correctly as per the manufacturer’s instructions, the generators are very effective in eliminating the odor.
  • The use of carbon filters is also quite common. The odor passes through the installed filters, in effect getting rid of the smell. Many Cannabis users can attest to the effectiveness of the carbon filters in Cannabis grow rooms.
  • The last tip to use in getting rid of the odor is the use of drops. These drops are available commercially under different brand names.

It is important to note however, that these deodorizing solutions are highly dependent on the size of the grow room. Carbon filters for example, have to be installed at strategic points in the grow room. If you have a large room, it means the use of many carbon filters. The same principle applies in the installation of air conditioning fans. Whatever the remedial choice, it is important to provide the right conditions for your Cannabis plants.
