Growing radish microgreens indoors is an excellent way to obtain fresh, organic vegetables from the comfort of your own home.

Radish Microgreens are a simple way to add healthy nutrients to your diet. We’ll go over all of the best tips for growing radish microgreens hydroponically, and they mature in less than two weeks.

You can grow these nutritious, spicy gems year round in an inexpensive indoor garden!

Before you begin hydroponically growing radish microgreens, you will need to gather your materials. These include the following low-cost items:

We like the pinkish Red arrow or China rose varieties of radish seeds and radish microgreen seeds. A growing tray or a container is required to hold the growing medium and seeds.

Coconut coir mat or rockwool cubes as a growing medium. Water spray bottle to mist your seeds when they are first planted.

A grow light or light source is required once the seeds have sprouted leaves.

Radishes, like microgreens, are simple to grow without soil. Here are the steps to growing your own food and harvesting radish microgreens:

1# Radish Seeds Soak

Because radish microgreens are so simple to grow, no soaking is required. Purchase enough seeds to fill at least a few trays.

2# Planting radish seeds

First, moisten your growing medium. Make sure it’s flattened out so it can be seeded easily.

Then, evenly distribute your radish microgreens seeds onto your growing medium, which could be rockwool cubes, coco coir, or our favourite hemp growing mats. A general rule of thumb is 10 seeds per square inch.

We don’t put much emphasis on perfection. Planting them too densely, on the other hand, will result in seed waste and the need to thin them out.

Mold may grow as a result of a lack of air flow. Give them a good misting, especially if you haven’t already soaked them.

3# Germination and Growth

Because your radish microgreen seeds require darkness to germinate, place a second tray on top with some weight. We frequently prepare a few trays at a time and stack them on top of each other. The more, the better.

4# Microgreens Growing

Check the status of your seeds. Remove their lids and place them under your grow light once they’ve mostly germinated (usually by day 3).

We recommend a grow light over a windowsill because they require consistent light. Microgreens on a windowsill can become leggy as they grow toward the light source.

When the top of the growing medium feels dry to the touch or the tray is light when lifted, soak them.

Fill the tray with an inch or so of water, allowing the plants and growing medium to absorb it.

Tilt the tray back and forth to distribute the water evenly throughout the growing medium. Continue until they no longer absorb water.

5# Harvesting Radish Microgreens

Radish microgreens are ready to harvest in 6 to 10 days. For hydroponic radish microgreens, harvest radish microgreens with scissors or a sharp knife near the base of the stem when they’re about 2-3 inches tall.

For the freshest microgreens, harvest only what you need each time. If you leave them for too long, they will develop full-grown radish bulbs.

We did this as an experiment once, and it was a lot of fun. They did, in fact, develop into radishes.

6# Radish Microgreens Storage

Microgreens can be successfully stored in a variety of ways. When stored properly, they can last for a couple of weeks. Our preferred method is to simply leave them to grow until ready to harvest.

If you must harvest, the best way to store radish microgreen seeds is in an airtight container in the refrigerator.

If they become too wet, they will rot quickly. You can also freeze them, but don’t keep them in the freezer for longer than three months.

Growing radish microgreens is a great way to add some colour and nutrition to your diet.

Radish seeds are simple to grow because they do not require much light or water, making them ideal for those who live in apartments or do not have a green thumb. Radishes can also be grown hydroponically.
