FAQ and Tips for Growing Hydroponic Microgreens 

What are microgreens? 

Microgreens are young greens that are typically harvested seven to fourteen days after planting. They can be eaten whole, including the stem and leaves.

Microgreens are often used as a garnish or decoration, but they also pack a powerful punch in terms of flavor and nutrition. In fact, microgreens have been shown to contain higher levels of certain vitamins and antioxidants than their mature counterparts.

As a result, they are becoming increasingly popular with chefs and home cooks alike. So, if you’re looking for a little extra flavor and nutrients in your next meal, be sure to give microgreens a try. 

What are the benefits of growing microgreens hydroponically?

You can grow hydroponic microgreens year-round, regardless of the weather outside, and they don’t require a lot of space. Plus, hydroponic microgreens may be more nutrient-dense than those grown in soil, since it’s easy to control the nutrients. They are also less messy than growing microgreens in soil. 

Believe it or not, hydroponic microgreens require less water than microgreens grown in soil. 

I also love growing hydroponic microgreens because I don’t need to store soil, which is a big plus if you have limited storage space.

How to choose the best hydroponic system for microgreens 

When it comes to growing microgreens, there are a number of different hydroponic systems to choose from.

The type of system you choose will depend on a number of factors, including the amount and type of microgreens you want to grow.

I’m personally a big fan of growing microgreens in my AeroGarden, because it’s so easy. You can learn more about this through my article, The Ultimate Guide to Growing Microgreens Using the AeroGarden Microgreens Kit.

I also have used the following for growing hydroponic microgreens:

Regardless of which system you choose, it is important to make sure that you have all the necessary equipment and supplies before getting started 

The best hydroponic media for growing microgreens 

Here are a few of the different types of growing medium I use for hydroponic microgreens:

  • Handy Pantry Micro Mats – small (I use in my AeroGarden these when growing microgreens with small seeds)
  • Micro Mats – large (use these when growing hydroponic microgreens in a tray)
  • Micro Mats Confetti (I like these for growing hydroponic microgreens in any size or shape container)

In addition to the above recommendations, I’ve also made my own hydroponic growing medium for using in my AeroGarden. I share all about that in this article, AeroGarden Microgreen Growing Medium Alternatives.

It should also be noted that some claim you don’t need to use any nutrients when growing hydroponic microgreens. I personally take a middle of the road approach with this, and add nutrients on day 5 of growing hydroponic nutrients.

Harvesting and storing microgreens 

Microgreens are typically ready to harvest within about 10 days of planting. When the time comes, cut the greens at the base of the stem using sharp scissors. Be sure to handle the greens carefully, as they are delicate and easily bruised. Once the greens are cut, rinse them thoroughly with clean water. Store the microgreens in an airtight container in the refrigerator where they will stay fresh for up to a week.
