How Long Do Microgreens Take to Grow?

Microgreens have gained popularity in recent years due to their nutritional value and ease of cultivation. These tiny, nutrient-dense greens are typically harvested when they are young and tender, making them a perfect addition to salads, sandwiches, and other dishes. One of the most common questions among aspiring microgreen growers is how long it takes for these greens to reach maturity. In this article, we will explore the average growing time for microgreens and provide some insights into the factors that can influence their growth.

Average Growing Time for Microgreens

When it comes to the growing time for microgreens, there is some variation depending on the specific variety. However, based on the information provided in the sources, we can conclude that most microgreens can germinate within 2 to 3 days and are ready to harvest between 7 to 21 days.

Factors Influencing Microgreen Growth

Several factors can affect the growth rate of microgreens:

1. Variety

Different microgreen varieties have varying growth rates. While some may sprout and mature within a week, others may take a bit longer. It’s important to research the specific variety you are growing to ensure you have an accurate understanding of its growth timeline.

2. Growing Conditions

The growing conditions significantly impact the growth rate of microgreens. Let’s take a closer look at the optimal conditions for microgreen growth:

Adequate Light

Microgreens require sufficient light to carry out photosynthesis and develop properly. Most varieties need at least 4-6 hours of direct sunlight or supplemental artificial lighting per day. Providing the right amount of light will contribute to faster and healthier growth.

Proper Temperature

The ideal temperature range for microgreen growth is typically between 55-70°F (18-24°C). Extreme heat or cold can slow down the growth process or even damage the plants. Maintaining a consistent and moderate temperature is crucial for optimal growth.


Microgreens thrive in a humid environment, especially during the germination stage. The recommended humidity level ranges from 40-60%. Higher humidity promotes successful germination, while slightly lower humidity levels encourage faster growth after germination.

Air Circulation

Adequate air circulation is essential for microgreens. It helps provide oxygen and nutrients to the plants, prevents the development of mold and mildew, and strengthens their overall structure. Ensure that there is proper ventilation in your growing area to create a favorable environment for your microgreens.

Suitable Growing Medium

Microgreens can be grown in soil or hydroponic systems. If using soil, it should be nutrient-rich, well-draining, and free from pathogens. Hydroponic systems offer precise control over nutrient delivery, ensuring optimal growth conditions for microgreens.


While the average growing time for microgreens is around 7 to 21 days, it’s important to note that specific varieties may have different growth rates. Understanding the optimal growing conditions, including light, temperature, humidity, air circulation, and suitable growing medium, is crucial for successful microgreen cultivation. By providing the right conditions, you can ensure that your microgreens grow efficiently and reach their full potential.
