Microgreens trays

Microgreens trays are compact cultivation systems that produce young, nutritious vegetables, gaining prominence in urban and sustainable agriculture.

About this subject

Microgreens are vegetables harvested shortly after germination, typically between 7 and 21 days, when they have developed their first true leaves. Microgreens trays are shallow containers, with or without substrate, designed to optimize cultivation in small spaces such as apartments or vertical greenhouses. This method requires little soil or coconut coir, water, and light, making it ideal for home or commercial high-value production.

The popularity of microgreens has grown due to their high nutritional density: studies indicate they can contain 4 to 40 times more vitamins and antioxidants than their mature counterparts. By 2026, the trend points toward automated indoor farming systems with stackable trays and LED lighting, meeting the demand for fresh, locally sourced food in urban areas. Brazil, with its diverse climate and strong agricultural tradition, has potential to excel in microgreens production, especially varieties like arugula, radish, and broccoli.

A curiosity: the short cycle allows up to 15 harvests per year in the same space, reducing waste and increasing sustainability. Additionally, trays can be reused with organic substrates, aligning with the circular economy. This system is also used in educational and therapeutic programs, teaching about life cycles and healthy eating.

Frequently Asked Questions

What are microgreens and how do they differ from sprouts?

Microgreens are vegetables harvested after germination, with true leaves, unlike sprouts which are consumed with seeds. They have a more intense flavor and higher nutrient concentration.

How to grow microgreens in trays at home?

Spread seeds on moist substrate (like coconut coir) in a shallow tray, cover lightly, keep in a lit area, and water from below. Harvest occurs in 7 to 14 days.

Why are microgreens considered a trend for 2026?

With increasing urbanization and demand for sustainable food, microgreens offer fast, local production with low environmental impact, ideal for vertical and indoor farming systems.
