Know before you buy
These sponges are designed for standard indoor hydroponic systems that utilize seed pod inserts. Please ensure your current system's basket dimensions align with the size of these sponges to ensure a secure fit.
It is common for organic materials like coconut fiber to develop surface mold during the growing cycle. You do not need to intervene; the mold is generally harmless to the plant and the sponge should simply be discarded once you have finished your harvest.
Each sponge features a pre-cut hole at the top. Simply drop your seed into the center hole, ensuring it is deep enough to stay moist but close enough to the surface to receive adequate light once it begins to sprout.
No, these sponges are intended for single-use only. Once your harvest is complete, the sponge should be disposed of to prevent the buildup of bacteria or root debris that could compromise your next batch of plants.
Thai coconut shell fiber is chosen for its superior air permeability and moisture retention. This balance ensures that roots receive enough oxygen to prevent rot while maintaining the consistent hydration necessary for rapid germination.
