Hydropnic Pod and Hole Cover

I wanted something for my hydrogardens I could add my own medium to without using rubber plugs. The cap is just to cover empty holes to prevent evaporation. I've been using 100% coconut coir with great results. You may want to sanitize the coir before adding to your hydro system. This style keeps so much loose particles from getting into the water resivoir. Layer height: 0.2mm Infill: 100% Supports: None
