How to Grow Microgreens Indoors
Hers is a simple way to grow these plant seedlings in 10 simple steps.
Step 1: Collect Necessary Equipment
- Here are the things you need to gather-
- Planting Tray
- Potting Soil
- Spray Bottle
- Shaker Bottle
- Microgreens Seedlings
- Covering Lid
Step 2: Pour Soil on the Planting Tray
First, you have to take the potting soil and pour it on the planting tray.
Step 3: Spray Water over the Soil
Then, you have to fill the spray bottle with water and keep spraying over the soil till it’s soaked all the way to the top.
Step 4: Pour Seedlings into a Shaker Bottle
After that, you have to take the shaker bottle and insert the microgreens seedlings inside it.
Step 5: Spread Seedlings over the Soaked Soil
Next, you will evenly spread the seedlings on top of the soil. Then, using your fingers, disperse clusters of seedlings to regions where there are fewer seedlings.
Step 6: Spray Water over the Seedling Covered Soil
Now, you will again pour water on the soil. This time the water has to soak both the soil and the seedlings properly. Then, slowly cover the tray with the lid.
Step 7: Wait for a Couple of Days
Let the soil and seedlings soak in the water. Give it some time to grow.
Step 8: Peek Through the Lid
After about 2-3 days, look under the lid without completely removing it. If it looks like the seedlings have started developing, move to the next step. Otherwise, wait for a couple more days.
Step 9: Spray Water over the Growing Seedlings
Now, you have to use the spray bottle to spray over the developing microgreens.
Step 10: Check for Growth
Wait for a while. Then check if the seedlings have grown into small plants.
How to Choose The Best Grow Lights for Microgreens
When shopping for grow lights for microgreens there are several things you need to consider; light types, colors, light intensity, and heat. Let’s discuss them in detail.
Type of Light
For growing plants indoors there are several kinds of light systems you can buy from the market. But the ones mostly used as grow lights for microgreens are as follows.
1. Fluorescent lights
These lights are commonly used for growing smaller plants at home. They are more economical than metal vapor and incandescent lights and also produce less heat than HPS lights.
Fluorescent lights are known to provide a full spectrum of lights for small plants to grow properly. These lights are inexpensive and widely available as well.
However, there are still some drawbacks to them. They use more power to run and the bulbs contain mercury inside. So there is the risk of your microgreens getting contaminated should the fragile tube gets broken or damaged.
2. LED lights
Short for Light Emitting Diode, LED lights are the most preferred grow light type for microgreens at home. Most growers nowadays prefer LED over all other light types since they are more accessible, consume the least power, and provide adequate light spectrum needed for the plants.
These lights are lightweight and cause less electrical interference as well. Since they are not made of glass and there is no toxic material inside, there is little risk of your plants getting contaminated with them.
One of the primary attributes to consider for grow lights is color. The color of a grow light is also known as spectrum. And as you can see, certain spectra of color are more suitable for microgreens than others.
The color ‘Red’ and ‘Green’ are more suitable for microgreens as they are associated with the flowering and vegetative stages of plant growth respectively. That is why microgreens do best when there is a lot of red and blue colors in the grow lights.
How would you know which color is the grow light? Look for a light that offers a spectrum between 400 nm – 700 nm as this falls within the red and blue wavelength ranges.
The heat produced by light is measured through Kelvin and most lights are labeled within the 2000K to 6500k range. The higher the number, the closer the light to natural sunlight.
Therefore, our general recommendation would be to pick lights that closely resemble the natural sunlight. For that, you can choose the full spectrum light between 5,000 – 7,000K for vegetative growth and 3,500 – 4,500K to promote flowering.
Bulb Intensity (Watts)
The power or the intensity of light is expressed through the wattage. Watts are important for showing the power capability of grow lights. The higher the wattage the intense the light.
Since the growing time of microgreens is short high-intensity light isn’t necessary. For a 10/20 tray on a rack, only 2/3 grow lights of 20 watts each works just fine.
How Much Light Do Microgreens Need?
Most microgreens require some period of darkness at the beginning followed by light and darkness both for growth. The darkness period helps them to germinate and it takes from 6 to 8 days.
After that, you need to expose them to light daily. Each day they’ll require 12 to 15 hours of light and 9 to 12 hours of darkness.
Height of The Light Source
When the light source is weak they need to be closer to the plants. As the source becomes stronger you can move them away from the microgreens. It is important to consider that the heat of the light must not damage the plants in any way.
For LED lights and other cooler lights for the matter, the ideal distance from microgreens is usually 12 inches. But if you notice spots or wilting of the plants, it could be due to the heat from the light source.
FAQs on Growing Microgreens Indoor
Microgreens thrive under T8 fluorescent lighting, which has a color temperature range between 4000k and 6500k and a lumen output range between 1700 lumens to 2000 lumens.
In order to grow microgreens properly from seedlings, you will need a good quality grow light.
Microgreens are nutrient-dense, containing far more nutrients than fully-grown veggies. There are a number of healthy microgreens. Radish, broccoli, peas, amaranth, and arugula are some of them.
Radish seedlings are incredibly convenient to develop and produce a high yield. They also have a strong flavor profile and a pleasing hue that foodies seem to appreciate. And most importantly, they’re also packed with nutrients.
Since most microgreens are cultivated for a brief time, the light wavelength is less relevant compared to plants cultivated for extended amounts of time or until they blossom. For plants that require over 20 days to fully develop, a color temperature above 4500k is advised.
However, if at all feasible, obtain full-spectrum light since they are particularly effective in various situations.
We’ve tried to address all you need to know about microgreens and compatible grow lights for indoor gardens and labs in this article. Based on our assessments of the finest grow lights available right now, you will be able to pick the best grow lights for microgreens for your needs.
