Cauliflower has been around since the middle ages, and it’s claimed to have its origin in Cyprys. It’s one of the more nutrient-dense vegetables you can eat and enjoy in many different ways; roasted, steamed, grilled, boiled, fried, or eaten raw.

Cauliflower is commonly known as a large and round vegetable with its white head surrounded by green leaves. However, it also comes in a variety of green, orange, and purple heads.

Growing cauliflower in the garden is considered relatively difficult, and that could be because it thrives best in mild daytime temperatures. Growing them as microgreens is however easy.

How to Grow Cauliflower Microgreens

Growing Cauliflower microgreens is fast and simple. The seeds are fairly large, easy to manage, and you can with ease sow them thickly.

Growing timeline (estimated)
Preferred mediumSoil or coconut coir
Avg. seeds per tray (10/20 tray)42,5 gram
Germination period (blackout)Day 1-5
Growth time (sunlight)Day 6-8
HarvestDay 9-12


You don’t need to presoak the seeds. Simply fill a tray or other container with the medium of choice (preferably coconut coir or sterilized soil) and lightly compress it. Then sprinkle the seeds evenly across the surface. As these are larger seeds, they are easy to distribute, but if any of them have clumped together, gently use your fingers to spread them out.

Finish off by providing the seeds with water. You can use a spray bottle to give them a good mist.

Germination period (blackout)

Cauliflower seeds need to be placed in the dark for around five days.

You can cover your tray with another tray on top. After two to three days, when you see that the seeds have germinated, you can flip the cover tray and give the seedlings more hight to grow. 

Growth time (sunlight)

After the germination, you need to expose the growth to light for another 3-4 days. You will see that when the cauliflower seeds have grown to around 2-3 inches high, you can remove from the dark. Place the tray in indirect sunlight or under an artificial grow light. During this period, the microgreens will change from being yellow into green beautiful leaves with white stems and a hint of purple.

You should water your microgreens every morning and evening. Ensure they are not dried out, but as well you cannot oversoak them. The latter may cause them to grow mold and wilt.
