Keep your hydroponic system in peak condition with our premium port covers, designed to block light, pests, pets, and debris from entering your columns. While these covers won't completely prevent algae formation, they will keep it manageable, especially when used alongside proper pH management and our PHLO treatment. Crafted from food-safe PET-G filament using dedicated PET-G 3D printers, our covers ensure the highest safety standards. Available individually, but to maximize value, we recommend ordering multiple pieces due to the minimum shipping fee.
