Sorghum- not for microgreens!
Choosing the Right Seeds for Microgreens Matters More Than You Think
Choosing the right seeds for microgreens isn’t just about finding something that will sprout. It’s about safety, nutrition, and selecting varieties that are truly appropriate for microgreen production. Seeds must be untreated, but just as important, they must be the right species and cultivar for this purpose.
Recently, I had a conversation with a nutritionist who mentioned sorghum as a possible microgreen. It sounded intriguing, so—naturally—I dug into the research to see whether sorghum is a viable and nutritious option as a microgreen crop. What I found was surprising.
While cyanide levels in dry sorghum seed are negligible, research shows that cyanogenic compounds increase dramatically during sprouting. In fact, cyanide levels in sprouted sorghum can increase by 4,000–7,000%, with approximately 99% of the cyanide concentrated in the roots and shoots, not the remaining seed.
The takeaway?
Not every seed that can sprout should be grown as a microgreen.
What This Means for Home Growers
Experimenting can be fun, but when it comes to microgreens—especially those intended for consumption—caution and research are essential. Seeds from grocery store bulk bins or feed stores may be untreated, but that doesn’t automatically make them safe or suitable for microgreen growing.
