What Are Cover Crops For Marijuana Gardens?
Cover crops, which are sometimes also referred to as companion plants, are simply a farming technique that involves keeping a number of different agricultural plants alongside your marijuana plants.
Cereals such as barley, oats, or cereal rye are good choices. These cover crops produce a high level of plant biomass and cover soil surface and reduce sunlight penetration, which is critical for the germination of small-seeded weed seeds.
