    Tried a lot of different kinds of mix over the years. Nothing beats this stuff. I would highly reccomend it for starting seeds. I’m 74 years old. Always listen to what old people say.

  3. Kim Johnson (verified owner)

    Excellent, I love this a lot. I’m just starting my seeds and I love it.

    This is really good qaulity seed starting mix. I used to make my own mix and would even sterilize it but still had issues with fungus gnats. I have yet to have a problem with fungus gnats or damping off since I have started using this mix and my seedlings have been very healthy. This will be my go-to seed starting mix for now on. And I honestly don’t believe you save a ton of money making your own mix if you are a backyard gardener like me.
