Microgreen Podcast Episode 011 Show Notes

In this episode, we discuss the purpose of the blackout period for microgreens. 

As well as the two methods commonly used to blackout microgreens.

The methods are the Weighted Blackout Method and the Domed Blackout Method.

The two trays on the bottom use the weighted method; the weights and upper tray push the seeds into the soil.

This makes for better seed-to-soil contact, usually better germination, and more vigorous, sturdier microgreens.

The upper tray has a watering tray flipped upside, forming a dome above the seeds. This method works best for fragile stemmed microgreens like amaranth.

Don’t worry about the weight. Microgreens are strong enough to push it off.
