Broccoli Microgreen Seeds
Untreated, open-pollinated broccoli seed for commercial microgreen production. Broccoli produces fresh green cotyledons, tender stems and a mild brassica flavour. Its short crop cycle makes it a practical option for microgreen farms, market gardeners and growers supplying restaurants, retailers and fresh produce customers.
Broccoli microgreens are commonly harvested approximately 8–14 days after sowing, depending on the growing system and conditions. The seed can be grown in standard production trays using soil, coir, hemp mats or another suitable microgreen medium.

Growing Broccoli Microgreens for Commercial Harvest
Use approximately 25 g of seed per standard 10 × 20 inch tray as an initial trial rate. Fine-tune the rate for your tray dimensions, medium, airflow and target harvest size. Aim for even coverage without dense piles of overlapping seed.
- Prepare trays. Fill with an evenly moistened growing medium, or prepare your chosen growing mat according to the manufacturer’s directions.
- Sow evenly. Distribute seed across the surface. Pre-soaking is not normally required.
- Cover for germination. Mist as needed, then cover or stack trays according to your production method.
- Manage moisture. Keep the medium moist without leaving it waterlogged. Germination commonly takes approximately 3–5 days.
- Provide light and airflow. Uncover established seedlings and move trays into suitable natural or artificial light. Maintain ventilation and monitor moisture closely.
- Harvest cleanly. Cut above the growing medium when the crop reaches your preferred size, commonly around 8–14 days after sowing.
Flavour & Culinary Uses
