Types Of Pots For Growing Weed
Not all growing containers are equal. Some types of containers are better suited for some purposes than others. Likewise, growing pots don’t just differ in size. You can find containers from the classic flower pot to advanced smart pots or specialty containers for hydro systems. Learn what you need to know about growing containers for weed.
Selecting the optimal growing containers for weed isn’t always easy and straight forward. While you may be able to get by with the ol’ flower pot for your first grow, you want to choose the right growing containers, that provide for optimal growth and healthy plants. Let us take a look at the various types of growing containers available along with their differences, advantages and drawbacks.
If we were to simplify things a bit, the optimal growing containers for your weed plants would be those types of pots, that will provide your plants with the best possible environment for their roots. Healthy roots are essential for optimal nutrition and water intake and quite literally are the foundation for the healthy growth of your plants.
Knowing this, we can go from there when we want to find the optimal type of pot, since we can take into account what cannabis plants need for healthy roots:
The roots of your cannabis plants should never entirely dry out, since dried-out roots mean, that your plants would likely die.
Roots will also want adequate aeration and oxygen. When the roots have easy access to oxygen, this not only promotes fast growth, but will also help keeping mould and other growing troubles in check. A stale root zone depleted of oxygen will almost always lead to problems, if not entirely kill off your plants.
TYPES OF GROWING CONTAINERS AVAILABLE
If you visit a grow store or search around online to get some pots on the internet, you can find various types of containers for cannabis growing. Here are some of the most common types of growing pots.
STANDARD FLOWER POT
This is the good ol’ flower pot, that you can get almost everywhere for little money. They are most often made from plastic these days, but you can also find the old classic types, which are made from terracotta. If you get these standard flower pots, you will usually want to get them together with a matching saucer, that serves to catch your runoff water below the pot.
What’s important to know about these types of pots, is that you want them to have drainage holes at the bottom to avoid water logging. Not all pots come with prebored holes, sometimes you will have to break them out, before you use the containers to grow your plants.
Terracotta planters are heavier than plastic pots, but they can be a good choice. Terracotta has a natural ability to soak up and store excess moisture and can provide a cooling effect, which would benefit your plant’s roots in the hot summer months.
SMART POTS (FABRIC POTS)
The principle behind fabric pots, these so called “smart pots”, is to prevent, that your plants would become rootbound. Rather than growing in a cycle as would be the case in normal (closed) pots, smart pots made from fabric are air-pruning the roots as soon as they reach the sides of the container. This ensures constant new growth of roots and can help promote better plant growth.
Fabric growing pots or bags have the added advantage, that they make it pretty much impossible to overwater a cannabis plant. They can also easily be stored when not in use.
Make note, that the soil in smart pots dries out faster when compared to standard pots. To avoid the smart pots drying out too fast, you want to get double the size pots as you normally would. Of course this comes with the slight drawback, that you will require a bigger amount of growing medium. Since these types of pots leak water to the outside, they may not be suitable for all growing environments.
RQS FABRIC POT WITH AQUA-BREATHE LAYER
Royal Queen Seeds re-engineered the standard smart pot to create an improved version that continues to air-prune roots for enhanced growth while preventing overwatering. But it also includes several new features that make it easier to use.
If you’ve ever struggled to move a standard smart pot once your plants reach their full size, you’ll really appreciate the convenient side handles of the RQS fabric pot. They’re double-stitched and securely attached to the main body of the pot. You won’t believe the difference they make.
Although it’s not as clearly visible as the handles, the inner “Aqua Breathe” layer is the real game-changer. This inner layer of specialised material gives the RQS Fabric Pot another advantage over a standard smart pot. It allows air to flow through the pot, but ensures the water drains only from the bottom and not from the sides. Not only does this keep your grow space cleaner and preserve your nutrient mix, it prevents unsightly salt stains from forming on the sides of the pot.
Featuring the iconic RQS logo embroidered on the side in gold, the RQS Fabric Pot is a useful and attractive addition to any grow space. It can be used inside or out, in hydro or in soil, and it’s environmentally friendly. It’s washable, biodegradable, and available in a convenient 11-litre size.
Air pots make use of the same principles as the above mentioned “smart” pots. These are plastic containers with openings on the side, that provide automated “air-pruning” for the roots of your cannabis plant. Like smart pots, you will have to water more often, since these pots can dry out faster as compared to standard pots. Compared to fabric pots and grow bags, air pots have the advantage, that they are sturdier and won’t likely tip over. Since air pots are also leaking water from the openings at the side, you may want to set them above properly sized saucers.
Hempy buckets are providing a type of manual hydroponic system for growing cannabis plants. The difference to normal pots is, that the drainage hole isn’t at the bottom, but several centimetres above, which leaves a small reservoir of nutrient solution at the bottom of the hempy bucket.
As compared to soil grows, you would normally fill the hempy bucket with a mix of perlite and vermiculite or use clay pebbles and then feed the plants with hydroponic nutrients. The nutrient reservoir at the bottom of the bucket means, that you can water less frequently.
Since hempy buckets are a manual and passive way of hydroponic growing with no pumps for oxygen, you need to ensure, that the nutrient solution left in the pot won’t become stagnant, since this could lead to growing troubles.
CATCHING RUNOFF WATER WITH SAUCERS
Since you don’t want runoff water flooding your entire growing area, you want saucers placed under your pots. Normally, you would have a matching saucer for each of your growing containers.
Some types of growing containers like smart pots or air pots will require much bigger saucers, since excess water will flow down the sides when watering. Take this into account.
Most cannabis growers will likely get into a routine of frequently emptying out their saucers. This isn’t much of a problem if your plants are still small and you can easily access any pot in your growing area. Sometimes, in particular when your plants have grown taller, reaching to each and every pot and removing the saucers can become quite a chore, if not entirely impossible due to space constraints.
One solution for this problem can be if you use large trays underneath a number of growing pots as opposed to smaller, individual saucers under each. If you set this large runoff tray on a small incline, the water will usually collect in one space and you can then easily remove it with a shop vac.
Another more advanced solution can be with an automated pump, that can take care of the runoff water, that will collect in your tray.
WHAT SIZE OF GROWING CONTAINER IS BEST
Not all cannabis plants require the same size of growing containers. Some plants, for example autoflowering varieties, are not growing too tall and can do well in smaller or medium sized containers. When you select the size of your growing pot, consider the final size of your cannabis plant.
As a first starting point for selecting the right size pots, you can use pot sizes of approximately 7.5l for each 30cm of plant height. Just know, that not all cannabis varieties grow in the same way. Some strains can grow wide and bushy, while others can grow tall and slender, but this rule can help you get started finding the right sized pot.
GROWING CONTAINERS FOR SEEDLINGS
The same principles for healthy growth will apply for smaller containers for your seedlings. You need to ensure proper drainage for your seedlings as well. Since pots for seedlings can be very small and don’t hold too much growing medium, the soil dries out quicker, which means, that the risk of overwatering is lower.
Many cannabis growers use solo cups (“party cups”) for their seedlings without problems. Just make sure to cut drainage holes in the bottom of the cup.
Not always can it be recommended to start out cannabis plants in a small pot or cup and then transplant them later. Any repotting will always cause some stress to your plants, that you want to avoid.
For autoflowering varieties, that by their nature have a preset and rather short life cycle, it can often be best to start these plants in their final container. The reasoning here is, that you want to avoid any stunted and halted growth from repotting during their short growing life cycle if you want to max out your plant’s growth and yield.
TRANSPLANTING YOUR PLANTS INTO BIGGER GROWING CONTAINERS
Most of the time (with some exceptions as mentioned above) you will likely start out your seedlings or clones in small containers and transplant them to bigger pots when the right time has come. The reason here is, that a bigger container allows for a larger root system, that your now rather grown-up cannabis plant will require to get all her nutrients.
Transplanting on the other hand can always cause some stress for your plants and if not done carefully, could even kill your plant, say, should you damage the roots when transplanting. It is therefore important, that you move your plants, so that you don’t disrupt their roots in any way.
The best time to transplant is when your cannabis plant has developed a vast root system, but is not rootbound in the pot yet. Normally, the right time for a transplant is when your plant’s roots would show through the holes of your pot, as if they were searching for more room to grow. You want to avoid the plant having become completely rootbound though.
Carefully take out the plant from the first pot and try not to disturb the roots. In the bigger pot, make a hole in the middle of the growing medium where you carefully place the plant. Fill any remaining gaps in the new pot up with soil or whatever growing medium you are using.
When you transplant your seedlings, the best time for larger ports is usually when the seedlings have grown 3-4 sets of leaves.
If you want to avoid any type of potential growing troubles and want to keep it on the safe side, simply skip transplanting altogether and start your plants in their final pots. Your plants may start out slower than if you were to start them in smaller pots, but the reduced risk and then the less work from transplanting can be worth it, especially for less experienced growers.

Different Kinds of Pots for Growing Cannabis
Inicio » Products » Different Kinds of Pots for Growing Cannabis
There are many different kinds of pots for growing cannabis, and depending on where you grow, how you grow, and what pots you use, you’ll obtain one result or another. Not all pots are the same, and some have some pretty unique characteristics that differentiate them from others, like how airy they are or how the plants’ roots grow in them. In this article we’re going to explain the main differences between these pots so that you know which to use in your grow.
There are various kinds of flowerpot that are classified in two groups; plastic flowerpots and fabric flowerpots. There are many more kinds of plastic flowerpots than there are fabric ones. We’re going to talk about all of the different models so that you can easily tell them apart.
Your plants will easily adapt to each kind of pot, and depending on which on you use your plant will grow out a certain way – plants tend to grow in the same shape as their roots, which means they grow the same shape as the pot – if you place your plant in a square pot it will grow out in a square, and if you look at it from above you’ll see it has an X shape. If your pot is deeper than it is wide, then you’ll end up with a plant that’s taller than it is wide, and if you have a pot that’s just as wide as it is tall then you’ll have a plant that is as wide as it is tall.
Different Kinds of Pots for Growing Cannabis:
Square plastic flowerpot
Square plastic pots are generally the most used in growing cannabis, as they have the perfect size and shape to efficiently place more plants and make the most out of the space you have available, both indoors and outdoors. They’re much deeper than they are wide, so this will be reflected in your plants, making them the perfect shape for indoor growing and allowing you to place more side by side. Within the category of plastic pots, you can get both black and white pots – white pots are generally used for growing outdoors, where the sunlight can bounce off the pots rather than heating your roots and possibly stressing them out. Black pots are used indoors, where the light isn’t strong enough to penetrate the flowerpot, so they don’t heat up and stress out your roots. You can get pots from 0.20L, which are the smallest ones, up to 11L.
Aeropot flowerpots are pots that prune your plant’s roots so that they never stop growing secondary roots. When growing cannabis plants in this pot, the plants will grow just as wide as they do tall, and in some cases even wider. Due to having so many secondary roots your plants will grow out wide, kind of like bushes, and due to the fact that the roots are constantly growing, your plant won’t stop growing either until the roots have completely filled the pot. These pots are ideal for when you want to transplant your plant outdoors in your garden or in a guerilla grow, where you don’t want your plant to be 3m tall and easily visible by prying eyes; using these pots will guarantee you compact plants that are full of thick long colas of bud. For indoor growing these plants are ideal for mother plants, from which you’ll be able to get never ending clones until you need to transplant it to a bigger pot. Apart from all of that, your plant’s roots will get much more oxygen and they’ll feed much better than with a completely closed pot. Make sure to water them slowly, keeping away from the edges of the pot or the water might start flowing out the sides. Available in 1L, 3L, 6L, 10L, 15L, 25L and 50L.
Special Autoflowering Pot
These pots are plastic, 18L white pots that are absolutely perfect for growing bigger autoflowering strains such as Deimos, Magnum or Big Devil XL. Due to the fact that these autoflowering strains take about three months to complete their cycle, they need quite a lot of substrate in which to grow their roots. They also need to have more soil in order to retain more humidity for hot outdoor days. If you were to plant a three month strain in a 7L pot like other autos then they’ll have just enough water for one day when they’re fully grown – add on the fact that water evaporates when it gets hot, and you have a recipe for disaster. With this autoflowering pot you’ll have the perfect amount of space and substrate for your plants to get enough water that they need once they get bigger. Keep in mind that due to having so much soil at the start you need to water carefully, as if you over-water your plants at the start they can grow out rather dwarfed. Only available in 18L.
Round white handled pots
These white round handled pots are generally used for flowering seasonal outdoor plants or to keep mother plants indoors. When you grow cannabis plants you need to transplant them just like someone whose grown out of their shoes – your plants shouldn’t go into these pots right at the beginning, as the smallest size available is 30L and you’ll need to start off small and slowly move up to different, bigger pots – 3.5L, 7L, 11L etc. Generally, growers tend to let the plants grow out more in 11L pots and then do the transplant to a 30L pot once the light changes and your plants will soon begin to flower. You can even grow them in 30L pots and transplant to 50L pots once the flowering period rolls around. Available in 30L, 40L and 50L.
Cannabis grow bags
Grow bags gained quite a lot of popularity, as they’re extremely comfortable and easy to use. You need to clean normal flowerpots after every use, whereas with these bags all you need to do is throw them out and replace them with a new one – you can clean them if you want and reuse them a few times but it’s much easier to just chuck them out, which is what they’re made for. They’re much taller than they are wide, and they have a round and elongated shape, making them perfect for indoor growing where you can place many of them in small spaces. You can plant an enormous amount of clones in a small amount of space with the 2,2L or 4,4L bags. You can also plant pretty much any strain you’d like as they also come in a 44L format. They’re extremely easy to transplant, as all you have to do is cut the bag and place your plant and its roots to a bigger bag or to our outdoor garden. Available in 2.2L, 4.4L, 8.8L, 12L, 22L, 30L, and 44L.
These flowerpots are designed for growing in hydroponics or aeroponics, where the plant’s roots are suspended in clay balls, receiving a constant water flow. Depending on your system you’ll need a specific sized grid flowerpot. The smallest ones are used for cloning in hydro and aero, where you’ll need to have them in order to hold the clay balls while your clones put down their roots – they can also be used in systems such as Dutch Pot Hydro, where 5 of these little pots are used with a 12L flowerpot. The bigger ones are for different systems, like the 3” ones for Amazon by Nutriculture or 6” for the DWC Pot by Neptune. They’re extremely resistant and easy to clean and reuse time and time again.
Texpots are an innovative form of flower “pot” made out of fabric so that your plants’ roots can breathe properly, especially in dry climates. Due to being so aired out, the roots will be permanently prunes which will ensure a speedy and lengthy growth, which will lead to a bud-monster during the flowering period. You can wash them in any old washing machine, meaning that after every grow all you have to do is pop them in the washing machine, dry them and they’re ready to go again. They use a similar system to Aeropot flowerpots when it comes to growing roots, and they’re also round, although the big difference is that these pots are made out of fabric. You can get them in both black and white for indoor and outdoor growing; available in 1L, 3L, 7L, 15L, 25L and 50L.
