Best Net Cups for Hydroponic Gardening

While net cups don’t get a lot of glory in the hydroponic process, they’re important for the overall system. Not only do they hold the growing medium and keep it from either clogging or damaging the system, they also provide support for your plants. From different types and sizes, to quality, you will find that not all net pots will fit your needs. There are many things to consider when choosing which nets pots to use in your hydroponic garden.


Most commonly used in hydroponic gardening, net pots are used to keep the plants stable and locked into the system. They are effective in several types of hydroponic systems, including deep-water culture, nutrient film (NFT), aeroponics and they ebb & flow system.

Typically made from a solid plastic material, net pots boost drainage and air circulation. They have also proved to be beneficial for optimum root development and plant growth, because they allow liquids, such as your nutrient solution, to freely flow through the roots of your plants. As plants develop, the roots grow out of the holes in the net pot in search of the food they need to thrive. There are several things to consider when choosing a net pot.


When it comes to the net pots used in your hydroponic system, size matters. Typically, you can find net pots in a variety of sizes. The size you choose will depend on the full size and weight of the plants you intend to grow. For smaller plants and leafy greens, like spinach or kale, a smaller net pot will work. However, if you are planning to grow larger plants, like tomatoes, you may need larger pots to provide a bigger base and hold more of the growing medium.


Your growing medium will also make a difference in which net pots you choose to use in your hydroponic system. Look for net pots with smaller slots, as they do not let as much of the growing medium slip through into the system. In addition, net pots with more slots will give your plants a better base and better chance to remain upright. Net pots with larger slots are typically better for aeroponic gardening systems, which do not use a growing medium.


When choosing a net pot, you will also want to take the lip of the pot, because not all net pots are created equally. As plants grow, they will become heavier. In net pots without enough lip, this could cause the entire pot, along with the growing medium and the plant, to fall through the hole and into the nutrient solution. This inconvenience could cause problems in your system, so you want to do your best to prevent this from happening.

If you are still not sure of which size net pots you will need for your hydroponic garden system, you can use these as a guideline:

  1. 1” Net Pot – Best for starting seeds, cloning plants, and smaller plants
  2. 2” – 4” Net Pots – Best for starting seeds, cloning plants, and small/medium sized plants
  3. 5” – 6” Net Pots – Best for medium/large sized plants
  4. 6” Net Pots & Above – Best for large plants and trees
