Microgreens trays

Microgreens are young vegetable greens harvested early, packed with nutrients, grown in trays, popular in gastronomy and urban farming.

About this subject

Microgreens are seedlings of vegetables and herbs harvested 7 to 21 days after germination, when the first true leaves appear. Despite their small size, they concentrate nutrients such as vitamins C, E, K and antioxidants, often containing 4 to 40 times more bioactive compounds than mature plants. They are grown in shallow trays with light substrate like coconut coir or peat, in greenhouses or controlled environments. Irrigation is done through misting to prevent stem damage. Seeds are sown densely and lightly covered. LED grow lights speed up growth and ensure vivid colors. The short production cycle allows multiple harvests per month. Popularized in haute cuisine since the 1980s, microgreens like radish, broccoli, sunflower and pea are used to decorate dishes and add texture and intense flavor. In Brazil, production has increased in urban gardens and vertical farms, driven by healthy diets and interest in fresh foods. Microgreens can also be grown at home with simple trays and good light, offering a sustainable option for functional food.

Frequently Asked Questions

What are microgreens and how do they differ from sprouts?

Microgreens are seedlings harvested after the first true leaves develop, unlike sprouts which are consumed whole (root, stem, seed) after 2 to 3 days of germination. Microgreens have a stronger flavor and are grown in soil or substitute.

Which microgreens are easiest to grow at home?

Radish, broccoli, sunflower and wheat are considered easy because they germinate quickly and tolerate small variations in light and humidity. You only need a tray, substrate and indirect light.

Are microgreens more nutritious than mature vegetables?

Yes, studies show that microgreens can contain 4 to 40 times more specific nutrients, such as vitamins and antioxidants, compared to mature plants. However, the nutritional profile varies by species.
