I was at the garden store two days ago to grab some pots and dirt for my new hibs! I stumbled upon this potting mix called happy frog potting soil. It seems like it is very high quality and has beneficial microbes added, worm castings and hummus. The soil reminds me of HVH potting mix in texture in color, so I am interested to see how this compares to Miracle grow that I add perlite to, which all my plants are growing in now. If anyone has experience with this mix feel free to comment!
