Smart soil replacements kits and bottle top planters

They are great. I will be ordering more soon. I was using another company's bottle top replacements to use my own potting soil. 2 problems...first their units were too large (.75 ") for my wine and cobalt blue beer bottles and so the dirt came out if the bottom, not leaving enough room for roots to grow into bottle. Therefore, your bottle top units and your soil replacements are the way to go as they fit the bottles I want to use. I GIVE THEM BOTH A RATE OF 5+. Thanks
