The Best Flower Pots for Root Growth

In this article we’re going to have a look at various types of flowerpots used when growing cannabis; they’re designed specifically to boost root growth, making for much healthier, stronger plants that are ready for each and every growth phase.

What type of flowerpot should I use?

Usually, when you’re thinking of starting your own homegrown cannabis op, you take into account important things such as lights, what kind of substrate you should use, the seeds, the fertilizers that you might need, and many other things. Many growers tend to neglect one specific part of this process, and it’s the type of flowerpot; usually people think about the size and stop there. Typical plastic flower pots aren’t all that bad, although they can harm your plants’ roots and stop you from getting the best possible results. If you’re having issues with choosing the right flowerpot, just follow our advice and we’ll show you how to get much better results by working with better flowerpots. Root growth will vary depending on the type of flowerpot used, so you’ll need to take various things into account before choosing one.

Root growth inside flowerpots.

When roots start growing in a flowerpot, they grow both downwards and expand out to the sides via secondary roots, which soon begin to push up against the edges of the flowerpot. The main root stem will eventually end up reaching the bottom of the flowerpot and begin expanding outwards too, looking for water and nutrients. When this happens your plants run the risk of suffering from root suffocation, which is what happens when your plants’ roots begin to intertwine due to lack of space.


Root suffocation generally leads to a loss of root mass due to suffocation, which means your plants won’t be able to absorb any more nutrients from that portion which also stunts growth. This happens in pretty much every flowerpot that cannabis is planted in, and although plants don’t usually tend to die because of it, it does reduce growth and yield quite a lot.


One of the best ways to avoid this is to transplant your plants various times throughout their cycle, avoiding excess root growth in each flowerpot. The best way to do this is to transplant after germination, another during the growth period, with the last transplant right before the flowering period starts. This avoids root suffocation and gives your plants more space to keep growing.

Another possible solution is using fabric flowerpots or air pruning pots; these kinds of pots are designed to allow your roots to grow freely, avoiding typical spiral growth which can lead to root suffocation.


These kinds of flowerpots are made out of fabric that comes from recycled materials. This type of material essentially oxygenates your roots much more, making for a more balanced water/oxygen ratio in your plants’ substrate. This increases nutrient absorption, and decreases soaking as air can freely pass through the fabric, which reduces the chances of rot. A major benefit to this method is root growth; it allows your plants’ roots to grow out through the fabric and essentially, be pruned thanks to the lack of water. This creates a sort of positive stress in the roots, causing them to create more roots while still avoiding the spiral effect that can lead to root suffocation.


These flowerpots are made of two parts that you attach together, one of which is a sort of mesh base which allows oxygenation through the bottom of the pot. The second part is the wall of the pot itself, which is attached to the

base. The most interesting thing about this particular flowerpot is how it’s designed; the top walls of the plant are covered in holes that allow your plants’ roots to grow much more. One of the biggest differences between these pots and fabric pots is the base, which helps to reduce soaking incredibly and increases evapotranspiration.

As you can see, root growth is clearly good for your plants’ general health and state, but there are still many more benefits.


When you use special flowerpots like these, your plants will be able to absorb many more nutrients and more water, which significantly increases plant growth; this means bigger plants that produce more branches, shorter internodes, and therefore a large increase in yield. You’ll also be able to decrease growing times thanks to the fact that your plants will grow much faster, taking a few days of the transition to the flowering period.

In this article we're going to discuss the best flowerpots for root growth, making for healthy roots, healthy plants and larger yields.



The Experts’ Choice

Welcome to the Air-Pot ® website

If you are a commercial grower please go to our Nursery website.

The revolutionary design of the Air-Pot container actively enhances the growth and health of plants. This short video explains how it works.

Revolutionary Design

The ground-breaking design of the Air-Pot container has been continually refined over twenty years and is now in its sixth generation.

Every detail has been enhanced to guarantee healthy root development and maximise aeration. Additional oxygen in the growing medium leads to healthy bacteria and better nutrient release. At the same time the shape of the wall eliminates root circling and encourages the development of a mass of healthy fibrous roots. The additional roots mean better take up of nutrients and water leading to faster growth and healthier plants.

Toughly constructed from recycled plastic Air-Pot containers can last up to ten years or more.

Fantastic Roots

For plants to thrive they need healthy roots, but standard pots deform roots and this seriously compromises the health of the plant.

Air-Pot containers do the opposite, actively enhancing the plant by making it develop a mass of healthy fibrous roots. This maximises the ability to absorb nutrients and water leading to faster growth.

For Growers who know

For many years the Air-Pot container has been the choice of expert growers around the world who use it in all areas of horticulture from food production to growing the largest trees.

Only trees grown in Air-Pot containers were used for the landscaping of London’s Olympic Park and the system is relied on by the world’s leading horticultural institutions for their vital programs of research and conservation. At the Royal Botanic Gardens Kew over three thousand species of plant are now grown in Air-Pot containers.
