This video shows if your seed starting mix is too dense, you’re likely setting yourself up for problems without realizing it. Even if it looks rich and healthy, a heavy mix can lead to poor root growth, too much moisture, mold, fungus gnats, and other issues that can affect your plants right from the start.
The good news is it’s an easy fix. You can lighten the mix by adding things like peat moss, perlite, or coconut coir, or just blend it with a better seed starting mix. A small adjustment early on can make a big difference, and it’s one of those areas where using the right materials upfront can save a lot of frustration later.
