Let’s Talk Mold! 😅
Hey~! Josephine here 🧑🌾
I’ve been thinking about making a “Mold Post” for a while now because it was one of the biggest challenges we faced when we first started growing microgreens. Seriously, it took us an embarrassingly long time to get it under control! 🙈
Since we’re in Utah, a pretty dry climate, finding that perfect balance of temperature and humidity was tough—mold loves to sneak in under the microgreen canopies when things get a little too damp. But after lots of trial and error, we finally figured it out, and I want to help you overcome mold much faster than we did!
Here’s what we learned to prevent mold from creeping in:
🌀 Airflow is key! Keep a fan nearby to make sure your microgreens aren’t suffocating under still air. We bought nifty tiny fans that clamped onto the side of our shelves.
🌡️ Keep temps between 65°F - 75°F. Mold loves it warm and humid, so don’t let things get too toasty.
💧 Water from the bottom whenever possible, so the tops stay dry. Mold thrives in wet, dense canopies! Keep the top of the soil dry!
⏲️ Harvest on time. Letting your microgreens sit too long increases mold risk. Stay on schedule!
If you do spot mold, here’s what can help:
🧴 A light spray of hydrogen peroxide (diluted with water) can knock out mold in early stages.
🚿 Hypochlorous acid spray is another safe and effective option for tackling mold before it spreads.
A fun tip: If you spritz just a bit of plain water on the suspected infected area, you can figure out if it's mold or mycelium. If it seems to "shrink", it's mycelium (root hairs). Good sign of strong germination 👍 If it's unaffected, it's mold! 🦠 kill it!
Mold can definitely be a headache, but with the right steps, you’ll beat it in no time! 💪 Got any mold or other pathogen struggles of your own? Leave a comment and picture-- we'd love to see what we can help with!
