11 Proven Ways to Stop Mold on Microgreens Unless they're Beautiful Root Hairs
Preventing Mold
There are at least 8 things you should do to prevent mold from growing in your microgreens. Keeping equipment clean is one of the best methods to prevent mold.
Another overlooked factor is soil. The longer soil sits around the more chance it has of collecting and growing mold spores.
Make sure the soil you buy hasn't been sitting around and that it hasn't under gone a lot of temperature swings. This can cause condensation in the bag and we all know that mold loves moist soil.
Also, be sure to take soil of the bag as soon as you get home and store it in a sealed tote that has some air space.
See the article for more ways to prevent mold from growing on your microgreens. Especially, how to treat the seed.
Killing Mold
Once mold starts growing it's not the end of things.
Mold can be killed if treatment begins as soon as you see the problem.
There are some environmental actions you can take to help get rid of mold. If you can, put the tray in sunlight. Sunlight is a mold killer. If that's not possible. Elevate the tray so it's close to your LED lights.
Second, increase airflow around the tray. Instead UBS computer fans on the growing rack or put a fan near the trays to increase air circulation.
Don't put the microgreens in a hurricane. A steady gentle breeze is good enough.
Mold Killers
We recommend three solutions to mist onto a microgreen tray that has growing mold.
These are Food-grade Hydrogen Peroxide, Vinegar, and Grapefruit Seed Extract. Yep, grapefruit seed extract.
We will have a separate article on using grapefruit seed extract soon.
The dilution and how to use the solutions are discussed in the associated article.
We hope that you never have to worry about mold on your microgreens. But at least you know where to get solutions if that does unfortunately happen.
