Indoor Seedling Troubleshooting - Ep. 288

Indoor Seedling Troubleshooting - Ep. 288

Author: Karin Velez February 17, 2026 Duration: 21:57

Today is a clinic episode, a Seedling Troubleshooting Clinic to be exact, because if you’re starting seeds indoors, something is eventually going to look weird. A tray that was perfect yesterday is suddenly leaning. Something looks fuzzy on the soil surface. Or a seedling that seemed fine just flops over.

The good news is most seedling problems come from a small handful of causes, causes that we can actually control - light, temperature, water, airflow, or sanitation. And once you know what you’re looking at, you can usually fix it quickly or at least stop it from spreading to the rest of your tray.

So, I’m going to give you a simple diagnostic checklist and then we’ll walk through the most common seedling symptoms and what to do about each one.

Let's dig in!
