Groweze Seedling Sponge

These sponges are designed for single-use to prevent the spread of pathogens or mold between growing cycles. Once your seedling has been transplanted, it is best to discard the sponge to ensure a sterile environment for your next batch.

While these sponges are chemically neutral, it is good practice to soak them in water with a balanced pH level before inserting your seeds. This ensures the medium is primed and ready to support immediate germination.

Yes, the pre-formed slots are specifically designed to hold both seeds and plant cuttings securely. The material provides the necessary aeration and moisture retention to encourage root development for both propagation methods.

These circular sponges are sized to fit most standard hydroponic net pots. However, we recommend checking your specific net pot diameter to ensure a snug fit that prevents the sponge from falling through.

During the initial germination phase, plain water is usually sufficient. Once the seedling develops its first set of true leaves and begins to establish a root system, you should introduce a diluted hydroponic nutrient solution to support ongoing growth.
