Below you will find a list of the equipment needed to grow nasturtium microgreens. Although some pieces of equipment are labeled as optional, we recommend getting them as they will ensure a bountiful harvest.

Nasturtium Microgreens Starter Kits

A nasturtium microgreens starter kit provides you with the pieces of equipment needed to successfully grow microgreens. We recommend purchasing the Deluxe Microgreen Starter Kit from True Leaf Market. This kit provides you with a sampling of microgreen seeds, growing medium, grow trays, a misting bottle, and more.

Specific Equipment Needed for Nasturtium Microgreens

If you prefer, you can purchase each piece of equipment separately. Here are the pieces of equipment you will need to successfully grow nasturtium microgreens.

Nasturtium Microgreens Mason Jars

Nasturtium microgreen seeds are quite large compared to other microgreen seeds. They are about the size of a chickpea and have a hard outer shell that must be soaked in warm water for about 4 hours. We recommend using a pint mason jar with a screw top lid for soaking your microgreens. This setup will allow you to drain the water without losing any seeds.

Nasturtium Growing Medium

Nasturtium microgreen does best in a soilless growing medium like coconut coir or seed starting growing medium. You want a growing medium that is fine grained and drains well. This type of growing medium will help your microgreens grow strong roots and prevent soil borne diseases like root rot, mold, and powdery mildew.

Coconut Coir

Coconut coir is created using the husks of coconuts. The husks are gathered, dried, and then ground to a fine pulp. Then, the coconut coir is compacted and sold in blocks or disks. Once the coconut coir is dampened, it expands in size and is ready for planting.

Seed Starting Soil

Seed starting soil is a fine grained growing medium that provides young, tender plants with additional nutrients. Because the seed contains everything your microgreens need to grow, these additional nutrients are unnecessary.

Nasturtium Growing Trays

You will need a total of three trays for your nasturtium microgreens. One tray will be used to hold your growing medium. This tray will need to have drainage holes. The remaining two trays should not have drainage holes. We recommend using 10 inch by 20 inch grow trays.

Growing Tray with Drainage Holes

The grow tray with drainage holes allows you to plant your seeds in your growing medium and then water from the bottom. As the growing tray with holes sits in water, the growing medium is able to draw the water upward into the soil. This setup helps prevent overwatering which can drown tender microgreens.

Step by Step Growing Guide for Nasturtium Microgreens

Growing Nasturtium microgreens is not difficult when you follow our step-by-step instructions. We will guide you through preparing your microgreen trays to harvest and store your Nasturtium microgreens.

Step 1 Prepare Your Growing Trays

You will need about 2 ounces of Nasturtium microgreen seeds for each 10 inch by 20 inch growing tray. These seeds must be soaked before planting.

Place your nasturtium microgreen seeds in your mason jar and cover with warm water. Allow them to soak for about four hours. Then, drain the water and rinse your microgreen seeds with fresh water. Drain them and spread them on a dry paper towel while you prepare your growing trays.

Grab your growing tray with drainage holes. Fill the tray to the top with your growing medium. Then, press down the soil to slightly compact it. Ensure that your soil extends to every corner of your growing tray and level. Add more soil if necessary until it is about three quarters full.

Once you have filled your tray with growing medium, it is time to thoroughly saturate the soil. You can do this by placing your tray of soil in a couple of inches of water and allowing the growing medium to draw the moisture up into the soil. If you prefer, you can spray the soil down with your misting bottle. Saturate the soil and allow the water to soak into the soil for 15 minutes. Then, spray again. Complete this process of spraying and waiting 5 times to ensure your soil is saturated from the top of the tray to the bottom of the tray.

Step 2 Plant Your Microgreen Seeds

Once you have prepped your soil, it is time to plant your seeds. Sprinkle your seeds evenly across the entire surface of the tray. The seeds should be evenly spaced in a single layer. Once you have scattered the seeds, grab a handful of growing medium and sprinkle a thin layer across the seeds. Press down firmly with your hands.

Step 3 Understand the Germination Process

When a seed is planted in the earth, it is covered with soil and watered. We mimic this by covering the planted seeds with an inverted growing tray. This will prevent light from reaching your seeds during the germination process.

When a seed is planted in the earth and covered by soil, it causes pressure and weight. This pressure or weight helps the plant to grow strong healthy roots. We can mimic this by placing a heavy book, stone, or weight atop the inverted growing tray.

Once you have prepared your microgreen trays for germination, place them atop your heating mats. Set the heating mat to 70 degrees Fahrenheit. The heating mat will help improve the germination rate of your microgreens.

Check the moisture level of your soil daily during the germination process. If the soil feels dry, mist the soil with your misting bottle and then replace the lid and the weight. It will take between 4 days and 7 days for your Nasturtium microgreens to germinate. Once 90 percent of your Nasturtium has germinated, it is time to remove the inverted grow tray.

Step 4 Place Your Microgreens Under Grow Lights

Once your Nasturtium has germinated, it is time to place them under the grow lights and turn off your heating mat. Nasturtium microgreens require approximately 16 hours of light and 8 hours of darkness. The grow lights make it possible to control the amount of light your microgreens receive.

Your microgreen grow lights should be placed about 12 inches above the microgreens. The microgreen planter's rack makes it easy to hang your grow lights. Finally, using a timer allows you to set when the lights will turn on and when they will turn off automatically.

Check the moisture of your soil daily. If the soil dries out, it can wreak havoc on your microgreens. Additionally, too much moisture can result in mold. If your soil dries out, place approximately 1 cup of water in the bottom tray and allow the soil to draw the moisture up for about an hour. Then, pour out any remaining water.

Step 5 Turn on Your Circulation Fans

Circulation fans increase the airflow around your microgreens. Place your circulation fans on the side of your planter's rack. When placing your fans, ensure the air blows across the top of the microgreens. Avoid allowing the air to blow across the soil as this will cause the soil to quickly dry out.

Step 6 Know When to Harvest

Your Nasturtium microgreens will be ready for harvest in approximately two weeks after planting. Unlike other microgreens that are harvested when cotyledons first appear, nasturtium leaves maintain their flavor and texture as they mature. Therefore, you should allow your Nasturtium microgreens to grow until they have about four leaves.

Because the flavor can change significantly in a matter of hours, it is important that you taste your microgreens daily once true leaves begin forming. When they reach the height of perfection, it is time to harvest your Nasturtium microgreens. Withhold watering your microgreens for 12 hours before harvesting as excess moisture will shorten the life expectancy of your microgreens.

Harvesting Nasturtium Microgreens

Harvesting is simple; however, certain steps must be taken to ensure maximum storage times. Begin by gathering your supplies. You will need a pair of sharp scissors or a sharp knife and some clean, dry paper towels.

Grasp your microgreens in one hand and using the other hand quickly cut the microgreens about an eighth of an inch above the soil level. Place the cut microgreens on the paper towels and continue to cut until the entire tray is harvested.

If you will be eating your Nasturtium microgreens immediately, place the microgreens in a bowl of cool, not cold water. Then, place the microgreens on a paper towel to dry before use.

If you will be storing your Nasturtium microgreens, make absolutely sure that no dampness reaches your Nasturtium microgreens as this will shorten your microgreens' life expectancy.

Storing Nasturtium Microgreens

Once you have harvested your microgreens, it is time to store them. You will need an airtight storage bag or storage container for your microgreens. In addition to this, you will need a clean, dry paper towel.

Gather your cut microgreens together and then wrap gently in your paper towel. Then, place them in a storage container or storage bag. Make sure that your microgreens have room in your chosen storage container to prevent bruising. Seal your bag or place the airtight lid on your storage container.

Then, place your microgreens in your refrigerator's crisper. When properly stored, your Nasturtium microgreens will last about one week in the refrigerator.
