Mold and algae growth on AeroGarden sponges is common in hydroponic systems, but it’s often a natural and manageable issue. While mold, particularly Trichoderma, can be beneficial to plant health by suppressing harmful pathogens and promoting root growth, algae can compete with plants for light and nutrients if left unchecked. To manage these issues, ensure proper moisture control, storage, and regular cleaning of the AeroGarden system. Using hydrogen peroxide for mold removal is safe, and blocking light to prevent algae growth is effective. Experimenting with alternative growing mediums, like coco coir or rockwool, can also support plant growth while reducing mold and algae concerns. Proper care and maintenance will help your AeroGarden thrive and keep your plants healthy.
