Best Practices for Indoor Grow Rooms

As the cannabis industry continues to advance, so does 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 space can benefit from.

Best Practices for Indoor Grow Rooms

Our favorite and most useful Indoor Grow Rooms practices

We've researched the best tips, tricks, and advice the internet has to offer (for now). From basic knowledge such as washing your hands and avoiding overwatering to considering vertical growing and getting innovative with your structure, and we've compiled a list of our favorite and most useful practices.

  1. Implement forced air circulation
  2. Effective ventilation will stop insects from breeding
  3. Utilizing efficient technology such as double-ended HPS bulbs to get more yield out of the same square footage (with fewer lights)
  4. Using air filtration systems will control odor, dust, and particulate while preventing mold spores, mildew, and fungus, and creating an efficient airflow pattern
  5. Think wholly while planning the layout of a growing space. Consider different ways to maximize space and streamline workflow for maximum efficiency
  6. Don’t overcrowd a room
  7. Control the environment by keeping the grow room a closed space
  8. If your air intake comes from outside install a commercial air filter to avoid pests and disease
  9. Use proper spectrum
  10. Check for light leaks
  11. Check your pH regularly
  12. Don't be lazy, sweep and mop to remove contaminants regularly
  13. Clear out dead leaves and other plant materials from the grow room
  14. Sanitize and deep clean in between harvests
  15. Don’t let anyone walk into a grow room from directly outside (or from another grow room)
  16. Maintain the correct room temperature and a balanced amount of humidity
  17. Label everything and stay organized
  18. Schedule foliage spraying to stimulate root growth and improve node production
  19. Pick up pots to feel the weight of plants before watering to avoid overwatering
  20. Make room for the vegetative stage
  21. Consider flushing as a part of your routine
  22. Don't disregard the drying and curing stages
  23. Have fun growing!

How Clean is Your Grow Room Air?

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 contaminates 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 cultivators are investing in grow room air filtration to ensure they're producing only top-of-the-line product.

How Air Scrubbers Work

  1. A pre-filter catches large particulate to increase the lifetime of secondary filters.
  2. The bag filter captures mold, powdery mildew, dust, pollen, and other contaminants
  3. Optional HEPA filter catches 99.97% at .3 micron to provide the ultimate in clean air filtration
  4. Optional carbon filter generates an airflow pattern to circulate air through hundreds of pounds of carbon removing all odors
  5. Blower motor produces a high level of CFM and creates an air pattern in the room to ensure the air is properly circulated.

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's one that has proven to continuously pay for itself through years of plant protection.
