Used as a soilless medium, these tiny (1/4" square) cubes are a super clean, pathogen-free alternative to soil mixes. Plants get better nutrient uptake and excellent aeration in the root zone. Each cube has six surfaces to drain away excess water, so even if you water a lot, you’ll never get soaked roots. They’re also much lighter than other soil media or even clay pellets—your back will thank you when you need to move your pots around!

Pro-tip: This bag will fill approximately 23 one-gallon containers.
