1016041RGCE Organic Pro Seed Starting Mix, 16 Quart

Last year, after reading a bunch of seed starter/potting soil reviews, I settled on this brand. After 10 years of gardening I had the biggest, strongest young plants to transplant into the garden by spring. And last season was the most plentiful harvest ever. I can’t say scientifically that Pro Mix seed starting soil was the difference. But the difference was dramatic, and when something works, I stick with it!
