Microgreens trays

Microgreens trays are essential for growing young, nutritious sprouts in small spaces, perfect for urban agriculture.

About this subject

Microgreens are young seedlings of vegetables and herbs harvested shortly after the first true leaves emerge. Trays designed for microgreens are typically made of recyclable or biodegradable plastic, featuring drainage holes and a shallow depth (about 5 cm) to allow dense growth. They are used in vertical farms and home gardens alike, requiring little space and offering a fast cycle of 7 to 14 days.

Growing in trays facilitates control of moisture and light, resulting in sprouts rich in vitamins A, C, E, and K, as well as minerals like iron and potassium. Unlike common sprouts, microgreens are grown in a substrate (such as coconut coir) and cut near the stem, excluding roots. Their popularity has surged recently due to demand for fresh, sustainable food.

In Brazil, urban growers adopt stackable trays in hydroponic systems, optimizing water usage. Common species include broccoli, radish, sunflower, and cilantro. Trays can be reused for several cycles when sanitized, reducing waste and promoting circular economy practices.

Frequently Asked Questions

What are microgreens and how do they differ from sprouts?

Microgreens are young seedlings harvested after the first true leaf, while sprouts are germinated without leaves and consumed with roots.

What is the ideal tray depth for microgreens?

The recommended depth is about 5 cm, allowing drainage and enough space for initial root development.

How long does it take to harvest microgreens grown in trays?

Typically 7 to 14 days, depending on species and light/temperature conditions.
