This article is brought to you by Stewart Farms. Cannabis is green, but that doesn't mean that the cannabis industry is eco-friendly. Recent studies have shown that many large-scale indoor cannabis farms are often big-time polluters that contribute to smog and consume massive amounts of water and electricity. Fortunately, it doesn't have to be that way. Cannabis cultivators like Stewart Farms are leading the charge on sustainable cannabis farming by using aquaponics systems. Essentially, this means that Stewart Farms is using the eco-friendly properties of fish fertilizer to grow medical cannabis that is not only effective but patients also sustainable for the environment.
