Home to symbiotic & antagonistic interactions between the kingdoms of animals, plants, fungi, bacteria, and viruses.
Cover crops (aka living mulches ) and nurse crops (companion plants that support the main crop) play vital roles in improving soil health, protecting your grow, and building independent ecosystems. Typically not grown for harvest, these plants rather benefit cannabis by fixing nutrients, preventing pests, attracting beneficial insects, and building rich living soil.
Homegrowers across the world are adopting systems where cover crops mimic nature, keeping soil covered, moist, and teeming with microbiology for healthier cannabis growth.
Discover their agronomic benefits, usage, and growth considerations.
Get all in one! Preselected cover crops and companion plants, bundled together for their specific purpose. Whether you plan a new plot, or improve your current soil, Jonny got you!
A legume-powered blend to naturally boost soil fertility and reduce fertilizer needs.Ideal for no-till systems: sow in resting beds or between young cannabis plants (leave some spacing to avoid early competition). Clovers and alfalfa can be trimmed to manage growth; peas may be cut back or removed once mature. This mix supports continuous nitrogen release and can significantly reduce or replace synthetic inputs. Keep legumes slightly spaced from cannabis during early stages to avoid root competition.
A vibrant flower mix designed to attract beneficial insects, support natural pest control, and bring biodiversity to your grow. Ideal as a living perimeter or in strips between crop rows to create insect highways. Sow a few weeks before your main crop or alongside it in border beds, around greenhouses, or throughout vegetable and cannabis gardens. The continuous bloom cycles provide a steady draw for pollinators and predatory allies throughout the season.
Attention: Sunflowers stand tall as sentinels/trap plants for aphid. Make sure to plant them at a distance as they can attract aphids and may draw them toward your main crop if placed too close.
Best suited for outdoor and home garden spaces. While not practical for small indoor setups, it shines in regenerative systems focused on biodiversity, pest balance, and chemical-free protection.
A multifunctional groundcover blend that protects soil, supports beneficial insects, and enhances biodiversity. Best sown around the base of cannabis plants or in between rows, especially in no-till beds or low-disturbance systems. The clovers act as living mulch, while the herbs and buckwheat bring color, insect allies, and soil benefits. Maintain with light trimming as needed. Give young cannabis plants a little space early on. This mix is vigorous and thrives best when managed as a soft, living understory.
A focused, high-performance cover crop blend designed to regenerate soil before planting or between crop cycles by reducing compaction, boosting microbial activity, and naturally suppressing soil-borne pests. Sow prior year in spring or rotationally after harvest in late summer to early fall. Most species will winter-kill naturally, leaving behind decomposing biomass, open soil structure, and a revitalized microbial network. If mustard survives mild winters, mow or incorporate it at least 3–4 weeks before planting your next cannabis round to allow biofumigant compounds to break down. This preparatory mix sets the stage for high-performance living soil in spring, without the possible need for synthetic inputs. This is a before- or between-cycle blend, not meant to grow alongside cannabis. Avoid planting directly into freshly incorporated mustard or radish.
