Cannabis growers are constantly looking for new ways to improve their grow. Of course, these hobbyists want to achieve the best of the best when it comes to buds. After all, what is cannabis if it's not any good? There are many methods of improving a grow, but one that is proving exceedingly popular, and successful, is companion planting.


Companion planting is the process of improving the conditions of a growing atmosphere by planting beneficial plants close to each other. In fact, these individual plants protect against pests by producing a potent odor, which can stop the pests directly, as well as attract beneficial predators into the growing environment. Moreover, using companion plants can improve soil conditions through aeration and nutrient promotion. Furthermore, there are a few plants that provide structural support and can even diminish the need for added space.
