Oasis Horticubes Grow Cubes

While these are engineered specifically for hydroponic systems, they can be used for soil-based seed starting. However, keep in mind that the foam medium is designed to hold water and air in a way that mimics hydroponic nutrient delivery, so you will need to transplant them into soil once the seedlings are established.

No, the Horticubes are sterile and pathogen-free right out of the package. You can plant your seeds immediately without any additional preparation.
