What growing medium and containers should I use?

Seed-starting mix produces the highest yields and best flavor, especially for large-seeded varieties like sunflower and pea shoots. Microgreens grow one day faster in soil than on hydroponic mats.

Standard 1020 trays (10x20 inches) are the industry standard, but smaller 5x5 trays work well for testing varieties or growing on a countertop.

You don't need to buy specialized trays to grow your first batch of microgreens. Many common household containers work perfectly and cost nothing.

Hemp, jute, and BioStrate felt mats provide a soilless growing surface that produces cleaner microgreens with less mess. They're preferred by growers selling to restaurants where soil contamination is unacceptable.

Coconut coir is the most recommended growing medium for microgreens. It's naturally sterile, retains moisture without waterlogging, costs less than soil, and is a renewable agricultural byproduct.
