Indoor Vs Outdoor Cannabis Cultivation: Which Better Prevents Fungal And Bacterial Pathogens?

Permalink Report to webmaster

The challenge

If not properly screened for, life-threatening fungal and bacterial pathogens can be introduced to the human body through legal cannabis products; a 2017 study conducted in California found fungal and bacterial pathogens on 90 percent of the cannabis samples tested.

Common cannabis pathogens, including E.coli, Pseudomonas, Aspergillus, Botrytis cinerea and Fusarium oxysporum, can cause serious harm, especially for those with weak immune systems. That is why medicinal cannabis cultivators, indoors and outdoors, seek to eliminate those pathogens and other harmful substances. And to accomplish that, some companies choose to grow their crops in cleanrooms.

. Indoor

Indoor cannabis growers can potentially control the room's temperature, humidity, light intensity, and CO2 levels to achieve idyllic growth rates and conditions. Setting an ideal controlled cleanroom will not only improve yields and amounts of crops per year, but also will significantly reduce the ways a pest or a disease can reach a plant. Controlled indoor cannabis growers can stop cross pollination completely, and even drop the genetic deviation between plants, thus keeping the consistency of a strain much better than an outdoor field.

. Indoor Challenges

The right combination of moisture, temperature, humidity, and light can help accelerate the growth of both cannabis and its pests. For example, when humidity reaches above 80 percent, it widens the risk window for fungal, bacterial, and viral infections. When humidity drops below 70 percent, it can diminish yields with the photosynthetic efficiency dropping.
