Even the most experienced grower may be overlooking one of the most important elements of grow room cleanliness. Did you know that on average, the human eye can't see particles that are smaller than 50 to 60 microns? The size of most grow room contaminants are 1 micron or larger.
Professional growers put a lot of energy into fine-tuning each aspect of their growing space to ensure performance is running at the highest level of efficiency. Room temperature and humidity play large roles in the outcome of a harvest, but what about air quality?
Bacteria, pollen, powdery mildew, and mold are introduced to indoor grow rooms through the air and while carbon filters are excellent for odor control, they don't effectively capture small airborne contaminants that can damage and even destroy crops. Because of this, air quality ends up being the most overlooked detail in a grow room and is simultaneously responsible for the highest number of total loss crops.
As the cannabis industry continues to advance so does growing knowledge and many serious growers are investing in grow room air filtration systems or air scrubbers to ensure their cannabis is top-of-the-line. The initial cost of an air cleaning system can range anywhere between $400 and $4000 based on the measurements of the grow room and the grower's main concerns. While there's no doubt that an air filtration system is a large investment, it has proven to continuously pay for itself through years of plant protection.
✓ Implement forced air circulation
✓ Effective ventilation will stop insects from breeding
✓ Utilizing efficient technology such as double-ended HPS bulbs to get more yield out of the same square footage (with fewer lights)
✓ Using grow room air cleaners will control odor, dust, and particulate while preventing mold spores, mildew, and fungus, and creating an efficient air flow pattern
✓ Think wholly while planning the layout of a growing space. Consider different ways to maximize space and streamline workflow for maximum efficiency
✓ Don’t overcrowd a room.
✓ Control the environment by keeping the grow room a closed space
✓ If your air intake comes from outside install a commercial air filter to avoid pests and disease
✓ Check your pH regularly
✓ Check for light leaks
✓ Don't be lazy, sweep and mop to remove contaminants regularly
✓ Clear out dead leaves and other plant materials from the grow room
As the cannabis industry continues to advance, so do the knowledge and methods used by growers. While growing dynamics vary based on space, location, and a myriad of other elements, there are still some ground rules that any growing facility can benefit from.
