How Long Do Microgreens Take To Grow? (Data For 25 Greens)

People have started growing microgreens for a number of reasons. 

They are profitable and you don’t need a lot of capital to start growing microgreens.

In addition to those two main reasons, microgreens have a shorter life span when compared with full-size vegetables. 

So how long do microgreens take to grow?

Microgreens are easy to grow when you take the growing period into account. On average, most microgreens germinate in 2 to 3 days and can be harvested 7 to 14 days after germination. The harvesting time for different microgreens may vary, but this time period should cover a lot of profitable microgreens.

Now that we’ve given a generic answer, let’s take a look at some of the popular microgreens and see how long it takes for them to germinate and get harvested.

Growth Time For Microgreens (25 Greens Discussed)

The following section talks about microgreens and gives us the germination time and the harvesting time. 

If you’re interested in cultivating microgreens but not sure where to start, this section should give you a good idea. 

Arugula

Arugula

Arugula is a great way to start your microgreens farming.

It takes, on average, 2 to 3 days to germinate and 5 to 7 days to harvest after germination.

The peppery flavor of this microgreen makes it a good fit as garnishing on top of salads and sandwiches.

Radish

Radishes are another great starter microgreen.

The fact that it can grow in both cool and warm conditions makes it a good choice for many.

Radishes take, on average, 1 to 2 days for germination and 5 to 10 for harvesting after germination.

Beets

Beets, also known as beetroot, take a bit more time when you compare it with other microgreens.

The compound geosmin present in beetroot is responsible for its musty flavor.

Beets can take 3 to 4 days for germination and 10 to 12 days for harvesting after germination.

Broccoli

Broccoli

Broccoli is often considered a superfood by vegetarians and vegans.

The broccoli microgreens contain more nutrients and can be obtained in a short period as well.

It takes broccoli 2 to 3 days for germination and 6 to 15 days for harvesting after germination.

Bright Light Chards

These are very popular among chefs, thanks to their subtle yet versatile flavor.

It takes 4 to 6 days for germination and 9 to 12 for harvesting after germination.

Mesclun

Mesclun is not one but a combination of greens. It can include lettuce, spinach, sorrel, arugula, and other leafy veggies.

The time taken for complete microgreen growth is quite long here.

Mescluns take 3 to 4 days to germinate and can take another 35 to 45 days for harvesting.

Carrot 

Carrot is a popular vegetable that is also used as a microgreen.

When compared with other microgreens, carrots do take their sweet time (no pun intended).

Pre-Soaking Seeds

Soaking of certain microgreen seeds is done to reduce the germination time. This process gives us a jumpstart and can save a day or two.

Usually, seeds that have a thick cover benefit from soaking. They are soaked for 6 hours or overnight depending on the seed.

Some of the seeds that are fit for soaking are

  • Cilantro
  • Fenugreek
  • Coriander
  • Alfalfa
  • Barley
  • and more…

However, soaking is not a good option for all the seeds. 

Small microgreen seeds will not benefit from soaking and will turn into a goo which can become a problem in the cultivating process.

Some of the seeds you shouldn’t soak are

  • Flax
  • Arugula
  • Chia
  • Mustard
  • Basil
  • Lettuce
  • Amaranth

The time taken for each microgreen to grow depends on its life cycle. Sometimes, it is possible to fasten the process a bit with the help of soaking.

But when you compare with fully grown vegetables, microgreens are a lot faster to grow, market and consume.
