Quick Answer
Growing microgreens indoors offers significant nutritional benefits, with some varieties containing up to 40 times more vitamins and antioxidants than mature greens. They can be harvested in as little as 7-10 days, allowing for a continuous supply of fresh, nutrient-dense produce. Indoor microgreens also offer reduced pesticide exposure.
Nutrient Density
Growing microgreens indoors allows for precise control over growing conditions, such as light, temperature, and nutrients. This enables optimal nutrient uptake, resulting in higher concentrations of vitamins A, C, and K, as well as minerals like calcium and iron. For example, sunflower microgreens can contain up to 4.5 times more vitamin K than mature sunflower greens.
Variety Selection
Choose microgreen varieties that are specifically bred for indoor growing, such as red cabbage, kale, or arugula. These varieties tend to be more compact and produce higher yields in indoor growing environments. Consider growing a mix of varieties to create a diverse nutrient profile and to extend the harvest season.
Growing Techniques
To maximize nutrient density, use a soilless growing medium and maintain a consistent temperature between 60-75°F (15-24°C). Provide 12-14 hours of indirect light per day, using LED grow lights if necessary. Water microgreens with a balanced, water-soluble fertilizer at a rate of 1/4 teaspoon per gallon of water. Harvest microgreens when they reach 1-3 inches in height, using scissors to cut just above the soil line.
