For growers who have a little extra money to spend and want full control over their indoor garden, environmental controllers will allow you to automate the process. These devices are essential for if you’re away from the garden for a long period of time.

Soil is the most traditional medium for growing marijuana indoors, as well as the most forgiving, making it a good choice for first-time growers. Any high-quality potting soil will work, as long as it doesn’t contain artificial extended release fertilizer—like Miracle Gro—which is unsuitable for growing good cannabis.

Regulating temperature and humidity in your indoor grow space

Light emitting diode (LED) technology has been around for a while, and they are getting more efficient all the time. The main drawback to LED grow lights is their cost: well-designed fixtures can cost 10 times what a comparable HID setup would.

Inexpensive options include standard plastic pots or cloth bags, while some growers choose to spend more on “smart pots” or “air pots”—containers designed to enhance airflow to the plant’s root zone.

Plants need fresh air to thrive and carbon dioxide (CO2) is essential to the process of photosynthesis. This means you will need a steady stream of air flowing through your grow room, which will allow you to move hot air out of the space and bring cool air in.




To tie down your plants for training. You’ll want to use appropriate gardening wire or something similar to avoid damaging your plants.

Growing cannabis indoors can seem daunting, but once you’ve developed the skills, you may never go back outside! With the right knowledge and equipment, even rookie growers can achieve great harvests at home. Explore our overview on indoor growing to prepare yourself for the process.


“Policymakers and consumers aren’t paying much attention to environmental impacts of the cannabis industry,” Jason Quinn, an associate professor of the m echanical e ngineering Department at Colorado State University and lead author of the study, wrote in an email. “ There is little to no regulation on emissions for growing cannabis indoors. Consumers aren’t considering the environmental effect either. This industry is developing and expanding very quickly without consideration for the environment.”

Since temperatures and humidity across the U.S. vary widely, the authors’ model calculated the energy needed to maintain these indoor climate conditions by using a year’s worth of hourly weather data from over 1,000 locations countrywide. By using electrical grid emissions data from around the nation, the model then showed the greenhouse gas emissions that all that required energy would produce. In addition, the model accounted for the “upstream” emissions from producing and transporting water, fertilizers, fungicides, and bottles of carbon dioxide to grow houses, and also tracked the “downstream” greenhouse gas pollution from all the waste these operations send to landfills.

The authors say it doesn’t have to ruin your buzz, though. We don’t need to give up growing weed. We just need to start shifting the industry toward more outdoor growing operations.

As more states legalize weed, commercial production of it is increasing. These growing operations may not just be getting customers high—they may be getting the planet’s temperature higher, too.

It is easy to be pessimistic about the future. It is also easy to scientifically verify that…
