Having said that, sustainable cannabis growing doesn’t just apply to big-name players and cannabis corporations, and doesn’t exclude the location of your grow whether it’s indoors or outdoors. Mom and pop setups and even cannabis startups can also do the same when it comes to their exhausts, grow lights, and fans. And no matter what the size of your grow op is, you can still have total control over the quality of nutrients you use on your plants, since many pesticides and packaged plant fertilizers are made with chemicals that are harmful to the environment.
