As the name suggests, companion plants are helpful species that can be grown alongside your cannabis, indoors or out. Each species of companion plant has different natural attributes, delivering a wide range of benefits. Companion plants establish a natural defence against pests and other threats, without the need for artificial pesticides, fungicides, or supplements. By establishing crop diversity, companion plants encourage and support a natural ecosystem for your cannabis plants to thrive.

Even the smallest growing spaces can benefit from companion plants and the polyculture principle. Polycultures increase local diversity by encouraging and attracting various plant and animal species. Monoculture (single species cultivations) are more prone to disease, infection, and pests.


Companion plants bring a wide range of benefits to indoor and outdoor cultivation projects. By adopting a polyculture environment, home growers can take advantage of the biodiversity our comprehensive variety of companion plants provides. While the exact characteristics of each companion plant will vary from species to species, growers have found companion plants to be effective in supporting the following:

Repelling insects and small creatures (aphids, mosquitoes, caterpillars, spider mites, flies, mice, ticks, whitefly, lygus bug, beetles and leafhoppers), improving water retention, enhancing soil quality, and boosting cannabis growth.
