Does pot size matter in hydroponics?

Selecting the appropriate pot size is a crucial step in achieving optimal plant growth. Using pots that are too small can result in restricted root growth, leading to stunted plants with reduced vigour. On the other hand, a sufficiently large root zone allows for better nutrient uptake, ultimately resulting in healthier and more robust plants. 

Does pot size matter in hydroponics?

When it comes to growing healthy and thriving plants, choosing the right pot is just as important as selecting the right soil and nutrients. At Go Green Hydro, we understand that different plants have different requirements, and selecting the correct pot size and material can significantly impact your plant's health and yield.


What Size Pot is the Right One for You?

One of the most common misconceptions in plant growing is that a bigger pot is always better. However, the reality is that plants do not necessarily benefit from oversized pots unless they have the potential to fill them with roots. Pot sizes typically range from 4 to 14 litres, and the right choice depends largely on the strain you are growing. As a general rule, the bigger the plant is expected to grow, the larger the pot should be.

Using pots that are too small can result in restricted root growth, leading to stunted plants with reduced vigour. On the other hand, a sufficiently large root zone allows for better nutrient uptake, ultimately resulting in healthier and more robust plants. Thus, selecting the appropriate pot size is a crucial step in achieving optimal plant growth.


Different Types of Pots and Their Benefits

Aside from size, the material of your pot plays a crucial role in the overall development and health of your plants. Choosing the right type of pot is essential for providing the ideal growing environment, as each material offers unique benefits and potential drawbacks.

There are a variety of pot types available, each suited to different planting needs and gardening preferences. Understanding their properties can help ensure the best outcomes for your plants. The most common materials used for pots include plastic, clay and fabric, each pot material contributes differently to aspects such as water retention, aeration, temperature regulation, and durability, so its important to consider these factors based on the type of plants youre growing, your climate, and your personal gardening goals.

Whether you're looking for pots that help with drainage, encourage faster root development, or simply suit your garden's aesthetic, understanding the strengths and limitations of each type can help you create the best environment for your plants to thrive.


Plastic Pots

Plastic pots are widely available, affordable, and come in a variety of sizes. They are durable and easy to modify—drilling extra holes for better drainage is a simple task. Additionally, square-shaped plastic pots can help maximise your growing space.

  • Plastic Square Pot - made from high-quality plastic, ensuring durability, lightweight handling, and waterproof protection, making it an excellent choice for plant cultivation. Its sturdy build ensures longevity, while its lightweight nature allows for easy handling and repositioning. The square design not only enhances aesthetics but also maximises space efficiency, making it ideal for growers who need to organise multiple pots in compact areas.
  • Round Black Pot - crafted from durable plastic, designed to withstand the demands of outdoor environments for extended periods. Built for lasting performance, it offers reliable functionality for all your planting needs, providing a sturdy base for a variety of plants, flowers, and shrubs.

However, plastic pots do have some downsides. Most plastic pots do not provide insulation against extreme temperatures. In hot weather, roots can overheat, while in cold conditions, they may become too cold. This makes temperature regulation a challenge for growers using most plastic pots.


Fabric Pots

Fabric pots, typically made from horticultural fabric, have become increasingly popular among growers. These pots encourage air pruning, which prevents plants from becoming root-bound. The porous fabric structure also enhances aeration and drainage, reducing the risk of overwatering.

On the downside, fabric pots dry out faster than plastic pots, requiring more frequent watering. Additionally, since they are made from fabric materials, they lack sturdiness and may require extra support in certain setups. Similar properties apply to pots made from geotextile materials.

  • Root Pouch Grey - an excellent choice for growing healthy, vibrant plants, offering a variety of benefits that promote optimal growth. The fabric material is specifically designed to retain moisture while still allowing for proper drainage, ensuring that plants receive the ideal amount of water without becoming waterlogged. It also helps regulate air circulation around the roots, which encourages healthy root development and improves overall plant vitality.
  • Easyfeed Fabric Pot - made from high-quality, premium fabric, this pot is designed to improve soil aeration, ensuring that the roots receive adequate airflow, which is crucial for their overall health and development. By enhancing the exchange of oxygen and moisture within the soil, the fabric pot encourages strong root growth, resulting in healthier, more robust plants.
  • PLANT!T Round Dirt Pot - designed to provide superior growing conditions for plants. The breathable fabric of the pot plays a significant role in preventing the common issue of roots "circling," a problem that occurs in traditional pots when roots grow in a circular pattern due to limited space. This innovative design promotes the development of more robust and expansive root systems, leading to stronger and healthier plants.


Terracotta (Clay) Pots

A traditional choice, terracotta or clay pots have been used by gardeners for centuries. They are sturdy, visually appealing, and provide a solid weight to keep plants stable. However, when selecting terracotta pots, ensure they have adequate drainage holes, as not all come with them.

One key benefit of terracotta pots is their breathability. The porous nature of the clay allows for better moisture and air movement, reducing the risk of root rot. However, this also means they dry out faster than plastic pots, requiring careful monitoring of moisture levels. Due to their weight and fragility, they may not be the best option for frequent movers or growers with large-scale setups.


Air Pots

Air Pots combine the best features of multiple pot types, making them an excellent choice for serious growers. These pots prevent roots from circling, much like fabric pots, while also offering superior oxygen access to the root zone. This promotes healthier root development and overall plant growth.

Another advantage of Air Pots is their sturdiness. They are more durable than standard plastic pots and provide excellent drainage. However, much like fabric and terracotta pots, they tend to dry out faster, requiring more frequent watering. If you are using Air Pots, be mindful of maintaining consistent moisture levels.

  • Air-Pot - a revolutionary planting solution specifically designed to promote optimal root development, ensuring super strong, healthy plant growth. Its innovative structure, featuring a unique system of perforated holes and air channels, encourages root branching and air pruning, which are essential for cultivating robust plants. This cutting-edge air-pruning technology eliminates common issues seen in traditional pots, such as root spiralling and circling, by preventing the roots from becoming bound or restricted. As a result, the plant's root system is free to expand and grow in a more natural, healthy manner, promoting greater access to essential nutrients, water, and oxygen.


Selecting the right pot for your plants is a fundamental aspect of successful growing. Consider your plants size, growth potential, and watering needs when making your choice. Whether you opt for plastic, fabric, terracotta, or Air Pots, each material has its own set of advantages and drawbacks.

At Go Green Hydro, we recommend assessing your growing environment and plant requirements before deciding on the best container. By understanding the different pot options available, you can create the ideal conditions for strong and healthy plant growth.
