Cannabis planting that can cause mold

Molds related to cannabis cultivation. Houses or commercial buildings used for illegal cannabis cultivation suffer severe mold damage.

Cannabis cultures vary in size and duration of operation, so the extent of damage is extremely different from one place to another, and decontamination needs are difficult to evaluate properly. In addition, even large mold contamination is not always visible to the naked eye. It must be remembered that an indoor fungal contamination, even if hidden, can make the occupants sick. AIRTESTS, through an in-depth investigation, is able to assess the situation and provide a comprehensive plan for the remediation and rehabilitation of places where indoor cannabis cultivation has been conducted.

In most cases, undesirable fungal contaminants (pathogens, irritants, toxins and/or allergens) found in places where cannabis has been grown are Aspergillus, Chaetomium and Stachybotrys; these have an important potential to put the hosts in poor health, sometimes even seriously ill.

ASPERGILLUS: Aspergillus is an opportunistic pathogen with about 20 species, the most common being are Aspergillus fumigatus, Aspergillus flavus and Aspergillus niger. This is particularly problematic for people who have a fragility of the upper respiratory tract or the one who suffer from pathologies such as asthma and emphysema. Aspergillus fumigatus is an important pathogen to humans and is the most common cause of all forms of aspergillosis. While Aspergillus flavus is the second largest cause of human infections and is often associated with invasive aspergillosis in immunocompromised patients; especially observed during paranasal sinus infections. With its white color turning yellow and its black conidia, Aspergillus niger is one of the most common and easily identifiable species of the aspergillus genus. It is the third most common species associated with invasive pulmonary aspergillosis. It is also often the cause of aspergillosis and is the most common agent in cases of otomycosis.

CHAETOMIUM: Chaetomium is a cosmopolitan fungal contaminant that can be found in soil or decomposing organic material, but is most commonly found on wood or gypsum paper. It is a common agent of onychomycosis, or cutaneous or cerebral infections in humans. There are, however, few confirmed cases of human Chaetomium infection. Chaetomium are part of a group of fungi that cause infections often referred to as phaeohyphomycosis or hyalohyphomycosis. Brain abscesses, peritonitis as well as cutaneous and subcutaneous lesions may develop. Onychomycosis, both on the feet and on the hands, can be exceptionally caused by Chaetomium species in persons whose immunity is normal. However, the full range of Chaetomium mycosis, including onychomycosis, sinusitis, empyema, pneumonia and fatal disseminated brain infection, is found in immunocompromised hosts. Several articles report cases of infections where Chaetomium are identified as opportunistic infectious agents. In one case review, Chatomnium globosum was the most commonly isolated species in a group of nine clinical cases of Chaetomium infections. The diagnosis of pulmonary fungal infections is difficult in the absence of confirmation by culture; therefore, cases of Chaetomium infections may have been misleadingly attributed to Aspergillus, since some diagnoses were based solely on clinical symptoms and histopathological examinations.

STACHYBOTRYS: The fungal contaminant Stachybotrys is predominantly found in indoor environments (general surfaces are paper, wood and cellulosic compounds). This fungus is known to cause mortality in farm animals after they have ingested contaminated feed. In humans, it is believed that this fungus could be involved in cases of poisoning following inhalation or dermal absorption of the toxins it produces. Since Stachybotrys spores are rarely airborne, they are more likely to be identified by direct sampling of a contaminated area by swabbing or tape sampling. Stachybotrys is of interest to health professionals for several reasons; In particular, it should be noted that it may be involved in the disease of unhealthy buildings as this mold contaminates buildings with mechanical design problems or construction problems, or buildings whose inadequate operational strategy leads to problems of chronic excess moisture. Stachybotrys chartarum is the subject of multiple scientific studies because of its potential role in health problems associated with poor air quality in mold-contaminated buildings. These health problems could be attributed to the powerful mycotoxins produced by certain strains of S. chartarum.

Mold, spores, fungi and yeasts test.

Molds, spores and fungi present in high concentrations in the air are harmful to health. The discovery of mold in your home can lead to important work. It then becomes essential to conduct an air quality test to ensure that there is no mold in the walls, under the floors, and in the attic before buying a property like This article from the Journal de Montréal tells the story of a couple whose new house is overgrown with mold.

There are several factors that can cause mold to grow in a home, among these are long-standing (often undetected) water infiltrations, combined with poor ventilation that prevents moisture from entering the home and evaporate properly. There are also several situations that are more conducive to the development of mold, which must be addressed at construction. Refer to this article for more details on the causes of mold.

An air quality test may be necessary to know the condition of the house before buying it. It is even more important to carry out this test when the house has had several problems of water infiltration. Another reason for conducting an air quality test before buying a home is when it was used for a cannabis plantation.

Mold, post remediation report

Post-decontamination work, a mold test is needed to validate the work

After having repaired the problem and after having remediated the premises. It is important to carry out an air quality test to ensure the conformity of the work BEFORE the reconstruction. This report also allow you to prove to the next buyer that the premises are healthy for habitation purposes. Post decontamination air tests are applicable for situations where there has been mold, bacteria and asbestos.
