Dill repels spider mites, a must for the cannabis grower.

Dill (Anethum graveolens) with its fragile flowers, self-pollinates when mature and continues to grow in your garden year after year. It should not be planted near carrots because cross-pollination could occur, contaminating both species. With this basic guideline in mind, dill can be planted with almost any other companion crop. An herb that makes your creams more flavorful, dill is a good ingredient for your mayonnaises.

Dill should be planted directly in the ground. As a companion plant for cannabis, dill attracts beneficial wildlife such as bees and hoverflies, ichneumonid wasps and other useful insects. 

Mites do not like dill and will stay away from it, so it will be a good ally for the cannabis grower. Dill effectively repels aphids, cabbage caterpillars and beetles, while bringing a delicate scent to the environment, helping to mask the characteristic smell of cannabis crops.
