A net pot (also called a net cup or mesh pot) is a small plastic container with an open lattice or mesh wall structure, used in hydroponic systems to support plant roots while allowing nutrient solution to flow freely through the sides and base. Net pots hold growing media (clay pebbles, rockwool, coco coir) that anchor the plant while the mesh allows roots to extend into the nutrient solution below.
Key Facts
- Common sizes: 2-inch (seedlings, NFT channels), 3-inch, 4-inch, 5-inch (larger fruiting plants)
- Mesh walls allow free flow of nutrient solution, oxygen, and roots in all directions
- Standard fitting for DWC bucket lids, hydroponic tower systems, and NFT channel holes
- Reusable β soak in diluted bleach or hydrogen peroxide solution between grows
- Net pot size should match the plant's eventual root mass and stem diameter at maturity
- Larger net pots hold more media and offer better plant stability for tall or heavy crops
