Growing Microgreens

Now that you know what radish microgreens are let's get into the materials you are going to need to follow along in this guide.


You can grow radish microgreens with just a microgreen kit and a pack of radish seeds right by your window if you have a well sunlit window. If not, then I recommend you get an LED grow light. You'll also need a wired shelf to place the LED grow lights under.


Materials Needed:


First start with some radish microgreen seeds, I personally recommend the Sprout house Radish Seeds as they have given me the most success. Although you can use any radish seeds you may already have.


Step 1. Prepare The Growing Tray

Start with 2 10 by 20inch growing trays, one will be beneath the other filled with water. While the one above will have drainage holes so the water can reach the roots of the microgreens. This will prevent mold growth and overall just make the growing process so much easier.


Do not add water to the one below yet, first grab the tray without drainage holes and fill it with coco coir. Then smooth out the surface and mist it well with a spray bottle. If you don't have a spray bottle then just sprinkle water over the coco coir until it is well moisturized.


To make the tray with drainage holes just get a very sharp knife and slowly poke out small holes, simple and easy.


Step 2. Add The Seeds

Radish seeds are very small in size, it is very easy to plant a lot of these seeds so be careful when planting. Just sprinkle the seeds on top of the coco coir and spread the seeds well leaving some gaps in the cluster of seeds.


Step 3. Water and Cover The Seeds

Then just cover the seeds with more coco coir and flatten out the surface. Even if you don't cover all the seeds they will still grow really well. Then just water one more time.


Step. 4 Check Daily

Your microgreens should have the right balance of water from now till harvest. Now is the time to stop using the spray bottle and start adding water to the second tray below. This will prevent you from getting the leaves wet and prevent mold from growing.


Once they sprout all you have to do now is just give your radish microgreens at least 12 hours of light every day. Radish microgreens grow very fast and should be ready to harvest in a couple of days.


How To Harvest Radish Microgreens

Once the radish microgreens are about 3 inches tall they are ready to harvest. Now it's time to move your trays to a cool, shady place. If your microgreens are harvested when it is too hot, they will wilt very quickly after harvesting. If harvested when cool (late evening, early morning), they will tend to stay fresh and crisp.


Simply cut about half an inch above the coco coir, and there you go you have now successfully grown radish microgreens! Pretty easy right?


If you decide to let them grow larger, they get leafier, and then they get less crunchy. You can taste test them and decide when you think they are ready for you.


Washing and Drying Radish Microgreens

Use a colander to rinse your radish microgreens thoroughly under cold water. Dry the microgreens completely by spreading them over some paper towels and letting them air dry. You can also speed dry them by using a fan on a slow setting.


Cut microgreens are best if eaten right after drying, but can be stored loosely in a bowl in the refrigerator for several days. Do not try to refrigerate microgreens that are not completely dry.


How To Store Radish Microgreens

After you harvest your radish microgreens you might be wondering how you're going to store them. Just simply place them loosely in a bowl or container and put them in the refrigerator.


What Radish Microgreens can be used for

Radish Microgreens can boost the flavor of salads, sandwiches, and even soups.

The leaves of radish microgreens are low in calories, but high in fiber and are packed with nutrients. This indicates that a salad of these greens will help you feel full, thus reducing your tendency to snack between meals and overeat.
