Radish Microgreens are a great addition to your pantry, and this article will give information on how to grow Radish Microgreens. Learning the process will give you a supply of vegetables and save you a local grocer trip.

There are different ways you can grow Radish Microgreens. Some methods do not require a large garden or even soil. These methods are perfect for people who would like to grow Microgreens indoors.

Equipment You Need To Grow Radish Microgreens.

Growing Radish Microgreens is simple, and you have multiple options when it comes to growing Microgreens. Some materials are optional, and they vary depending on the method you use to plant your Radish Microgreens.

How to Grow Radish Microgreens Using Soil?

Some people swear by using soil to grow Radish Microgreens. Using soil can improve germination and grow more quickly, especially if you are growing them outdoors with enough sunlight.

Preparing Your Tray

You would need a planting tray for growing radish microgreens. However, you can use something as simple as a foil tray. You would need to punch some holes in the bottom to provide a slow drip method when watering.

Place Your Soil on Your Planting Tray

After punching holes at the bottom, place your soil in your planting tray or any container. Make sure to level the soil but do not fill it all the way up. Another thing to do is to make sure the soil is compact without any loose holes.

Soak Your Soil

After placing your soil on the planting tray, you should take your spray bottle and load it with some water. Spray the water on the soil and let the soil absorb the water. After the soil absorbs the water, spray it once again. Level out any spots that form on the surface.

Ready Your Radish Seeds

Soaking your seeds overnight can help increase their germination rate. Soak the seeds in a bowl of water overnight and drain the water before planting them. After removing the seeds from the water, you can now sow the seeds.

Calculate the Spacing Depending on Your Container

Load your Radish seeds on a shaker bottle. The shaker bottler allows about 90 seeds per gram. This bottle also allows you to spread the seeds evenly. The proper spacing for the Radish Microgreens is about ten seeds per square inch.

Sow the Seeds

You can use a Microgreen calculator to know how many seeds you need to sow for your container’s size. Spread the seeds on the container and sow them. It is better to have the seeds evenly spaced, but as long as the seeds are compact, your Microgreens should be fine.

Prepare for Germination

Carefully spray the seeds using the water bottle, making sure that they do not fly off the planting tray. Put the watering tray at the bottom of the planting tray to allow it to catch the water. Cover the planting tray and make sure no light reaches your seeds.

Wait for Germination

Placing the weights on top of your tray encourages your seeds to grow roots on the soil. Leave the seeds alone for two to three days and wait for them to germinate. There is no need to water as the seeds would not need as much water during the first three days. The cover also helps retain water.

Provide as Much Light as Possible

Radish Microgreens would need light to grow. Once they have germinated, you would need to provide artificial lighting like grow lights or LED lights if you are growing them indoors. Of course, natural sunlight works best if you are planting them outdoors.

Water from The Bottom

You can water your Radish Microgreens from the bottom. Fill up the water tray whenever you see that it has dried up. Make sure you do not overwater your Microgreens, or it can grow mold and destroy your plants.

Harvest the Radish Microgreens

Radish Microgreens only need about eight to ten days to grow fully.  Once the Radish Microgreens grow about two and a half to three inches tall, you can harvest them. You can tip the tray by forty-five degrees and cut the Microgreens just above the soil.

How to Grow Radish Microgreens Using A Growing Mat?

A new innovative way of growing your Microgreens indoors is a Growing Mat. There are specific growing mats used for Microgreens. Fiber Microgreens Pads can help you grow Microgreens indoors without causing a mess.

Prepare Your Mat

Growing Mats specifically made for Microgreens are available online. Choose your preferred Growing Mat and prepare them. You would need to cut the Growing Mat according to the container you are going to use.

Preparing the Container

After preparing your Growing Mat, you can choose to punch holes at the bottom of your planting tray. However, Growing Mats can absorb and retain more water. They are also thinner, so you can choose to water using the spray bottle method.

Place Your Growing Mat

After preparing your container, you can now place your growing Mat. Spray down your Growing Mat to ensure that they are moist before plant. Drain any excess water, making sure that the Growing Mat is just moist, not soaking wet.

Sow Your Radish Seeds

Just like with soil, using a shaker bottle can help you space your seeds better. Just make sure that there are about ten seeds per square inch, and they are compact. Gently sprinkle the seeds over your Growing Mat.

Cover Up and Wait

After sowing your seeds, you can cover up the container and put a weight on it. Make sure that your cover is not opaque, or light will pass through. Wait for seeds to germinate, which takes around two to three days.

Check the Progress

After three days, check the progress of the seeds that have germinated. If the seeds have sprouted and started to root, you can remove them from the cover. However, if the seeds haven’t germinated yet, spray some water and leave for another three days.

Bring Some Light and Warmth

Once the seeds have germinated, you can remove the cover and bring it to a place with ample sunlight. If you are planting indoors, any light source will do well too. A growing light can help improve the growth rate of your Radish Microgreens.

Let It Grow and Harvest

Let the Radish Microgreens grow for about eight to ten days. Keep the Growing Mat moist but not soaked. You can harvest the Radish Microgreens if they are already two and a half inches tall or more. 

How to Grow Your Radish Microgreens Using Wood Shavings?

If you would like a more environmentally friendly option, Wood shavings are also an excellent method for growing Radish Microgreens. Fine Wood Shavings or Wood Shavings used for pets like a hamster will do well in planting your Radish Microgreens.

Choose Your Growing Medium

Sawdust or Wood Shavings are well-tolerated by medium seeds like the Radish Microgreens. You can choose from Sawdust, Coconut Fiber, or wood shavings as your growing medium when it comes to growing your Radish Microgreens.

Spray Water on Your Growing Medium

To use the Sawdust or Coconut fiber as a growing medium for growing Radish Microgreens, you would need to spray water on them. Make sure they are moist enough so your Radish seeds can take root on them.

Compact the Sawdust on The Container

Using a shallow container can also work for growing Radish Microgreens. Put your moist sawdust or coconut fiber on the box and make sure they are compact. You can also press down the sawdust to make it tighter.

Sow Your Radish Seeds

Using the shaker bottle, sprinkle the Radish seeds on your Wood shavings. They do not have to be properly spaced but make sure there are enough seeds on the container. Spread the Radish seeds all over the container.

Cover the Seeds

You can use a paper towel to help you control the water better. If you chose to put a paper towel over the seeds, it could also help with the germination process. Cover the container with the lid.

Wait for Germination

Leave the seeds covered for three days and wait for them to grow. Some sawdust does not absorb or retain as much water, so that can affect germination. After three days, check the germination progress.

Check Germination Progress

If the radish seeds germinated after three days, you can transfer the container to a place with light. However, if the seeds have not germinated as much, feel the growing medium to see if it is dry and spray some water if need. Leave the seeds for another three days if they have not germinated yet.

Consistently Monitor and Water

Provide some light after the seeds have germinated. You can use LED or Growing lights for indoor growing, and natural sunlight works well for growing outdoors. Water the seeds every time you feel that the sawdust is getting dry.

Harvest Your Microgreens

After about ten days, your Radish Microgreens would have fully grown, and you can harvest them. Cut just above the root of the Radish Microgreens -to harvest them. You should cut what you need only to avoid spoilage.

How to Grow Radish Microgreens Using Growing Paper?

If you cannot find high-quality soil in your area, growing Radish Microgreens using Growing Paper may be for you. This method is also perfect for people who do not have a huge space for growing their Microgreens.

Prepare Your Container

You can use a shallow container if you are using a Growing Paper medium. However, it is still best to punch holes at the bottom and use a water tray to catch the water from your planting tray.

Soak the Paper on Water

You can soak the paper with water and drain the excess water. If you are using a planting tray with holes at the bottom, you can also put water at the watering tray and let the paper absorb the water. Make sure it is just enough to prevent your paper from shredding.

Sprinkle the Seeds

After placing the paper on the container and soaking it with some water, you can now begin to sow your seeds. Sprinkle your seeds all over the container and make sure there is enough space in between them.

Cover with A Paper Towel

Covering your seeds with another paper towel can help with seed germination. This process helps your seed with germination and retain more water. After covering the seed with a paper towel, cover the container to avoid any light.

Germination Process

Let the Radish seeds germinate for three days and check on them. If they germinated, they are good to go. If they did not germinate enough, you could leave the seeds for another three days covered, making sure the paper towel is wet enough.

Grow Your Radish Microgreens

After the Germination process, you can water your Radish Microgreens by refilling the water tray. Place the seeds in a place with ample sunlight or prepare a light source for your Micro seeds to help them grow.

Harvest Your Greens

After growing the Radish Microgreens for ten days, you can harvest them by cutting just above the root. Store the Microgreens properly to avoid any spoilage and harvest what you need only.

Is There A Way to Speed the Growing Process?

Radish Microgreens are one of the fastest Microgreens to grow. The whole process will take only eight to ten days, and you will be ready for a harvest. However, it may be beneficial to use soil if you would like to grow your Microgreens faster.

Some people also say that using soil can help give the Microgreens a better taste, but this is not scientifically proven. If you are growing the Microgreens indoors, using a growing light can help your seeds grow faster.

The growing process also depends on the germination process. If your seeds did not germinate, you might need an additional two to three days to help them germinate. To avoid this, make sure your growing medium is moist enough. You can also use a heating mat to speed up the growing process.
