The hydroponic system has been widely used in growing plants these days. The idea of growing plants without soil but using mineral nutrient solutions in a water solvent is actually interesting. When it comes to a hydroponic system, there are a few aspects to consider ensuring that the plants will grow and thrive. These aspects include the type of system used, the method of having the best nutrients, and the location of growing, whether indoor or outdoor. However, part of the overall hydroponic equation is the pot size.

The biggest question is: does a pot size matter for hydroponic gardening? We’ll answer this crucial question in the sections below. Keep on reading to learn more about the importance of pot size and what factors to consider when choosing one.

The importance of pot size

In typical gardening, plant lovers follow the same rules when it comes to using pots. They’ll usually put their plants into smaller containers and transplant them as they grow. In hydroponics, however, the process of potting up is designed to maximize the growing space of the plants and encourage their growth. This is where the pot size comes into the picture:

  • Small pots: With these, your plants can stand in a waterlogged environment for a long period. Over time, however, the roots can suffocate and start to rot.
  • Large pots: With these, they allow the nutrient solution to evaporate even before the plants themselves can absorb all the needed nutrients. As such, this can compromise the plants’ nutrient absorption.

Overall, choosing the right size of pots for your plants can make a huge difference in their overall growth and health.

Factors to consider for pot size

At this point, choosing the right pot size can help your plants grow and be adequately nourished. However, there are three key factors to consider when choosing the pot size, such as:

  • Plants: You have to factor in the type of plant you’re growing when looking for the right pot. For instance, you need a much smaller pot of around four inches when you’re planting seedlings or cuttings. When the roots are taking hold, you can then transplant it to a pot with about six to ten inches to encourage faster root growth.
  • Space: You have to factor in the space as well, which is determined by the type of hydroponic system. As you can see, an indoor hydroponic system has a limited area compared to an outdoor system. Apart from this, you’ll have to consider the height requirement. Make sure that your chosen pots for your plants suit the space where you’ll grow them.
  • Temperature: The temperature impacting your plants’ growth can play a major factor in your pot size choice. For instance, if you’re using HID grow lights for indoor growing, you’ll notice how your pots dry out easily. For this reason, you need to have a flood time for an ebb and flow system.


At this point, you now know that selecting the right size and type of pot is paramount for maximum plant growth and overall health. When looking for the right size, make sure to consider the plant itself, the space required, and the temperature as outlined above. With all these in mind, you can ensure that your plants will grow healthy, even in a hydroponic system!
