Choosing the right pot for your cannabis plants is essential for the success of your crop. One of the vital aspects of proper plant maturation and development is a strong root system. Healthy roots are synonymous with good harvests. Let’s take a look at which pots are the most suitable for growing cannabis.
There are several types of pots to meet different growing needs. But if we simplify it, what a cannabis plant needs is a pot that favours healthy root growth. Without this, the plant will have problems retaining water, absorbing nutrients and achieving good vigour in vegetative growth. When choosing the pots for your cannabis cultivation you should consider the following parameters:
There are different types of pots specially designed for growing cannabis. Below we detail the characteristics of each one.
The best pots for growing cannabis are those that facilitate optimal root growth and development: the plant needs the necessary anchorage and energy for explosive vegetative growth. It is said that the size and health of the roots corresponds proportionally to the size of the plant, therefore, if you want your plants to grow healthy and strong, choosing the right pot will be a key element.
As mentioned above, there are different types of pots to suit the needs of different growers. Below we explain the advantages and disadvantages of each one.
This type of pots are the most common for those novice growers who are taking their first steps and do not want to make a large initial investment. Within this category there are two types of materials:
This type of pots is generally the most used not only for cannabis cultivation but also house plants.
Air Pots are plastic containers with dozens of holes both at the base and on the walls of the pot. With this, better aeration is achieved, which accelerates the metabolic processes of the plant.
These fabric pots have revolutionized the cannabis industry with their many advantages. Today, growers all over the world (both small and large scale) prefer them to conventional pots.
The so-called Hempy Buckets are pots that function as a passive hydroponic installation. The irrigation drainage holes are placed on the sides about 5 centimetres from the ground, thus creating a kind of reservoir of nutrient solution at the bottom of the pot. This type of pots must contain a special substrate for hydroponics that usually consists of a base of perlite (the zone of the bottom of the pot up to the holes), and the rest coconut coir.
The proper size pot is a highly debated topic. For the purposes of this article we are going to give you a rule of thumb that will lead you to success. This said, you may find that in future cultivations you decided to augment this formula based on your needs. The formula is: 3L of soil per month of life the plant will live.
This means, that if you are growing autoflowering plants, which often finish by the end of their third month of life, a 9 -12 L pot will be absolutely adequate. On the other hand if you are vegging a photoperiodic plant outside, for an extended period, you may find that a 100L pot is the way to pull down kilos per plant at the end of the harvest season. Of course this sort of cultivation would require stepping up the size of the container as the plant grows.
If you’re growing autoflowering genetics, you should plant the seeds directly into the container it will be in for the entirety of its life. The reason for this is that autoflowering plants should not be transplanted, as the stress can cause them to freeze and stop their growth, something that can be fatal considering that they only have a 3-4 week vegetative period.
To some extent, the size of the pot directly impacts the size of the plant and the yield – however savvy growers know how to use smaller pots to get monster plants and monster yields.
In general, those who grow cannabis indoors choose black plastic square pots because they are the best way to take advantage of space, a very valuable asset in indoor growing. This type of pots are taller than wide and their square shape allows to fit as many plants as possible per square meter; therefore, they are a tool especially used by those who grow using the SOG technique.
When it comes to outdoor cultivation, each grower has his preferences, some use giant fabric pots to get real trees at the end of the season; others, on the other hand, opt for plastic pots that are easier to move if necessary.
More than the ideal pot to grow cannabis outdoors, we should talk about the one that should NOT be used: the black plastic pots. The reason for this is that the black colour absorbs more heat. In certain times of the summer, when the temperatures are very high and the sun hits the pots directly, the roots can overheat too much and this harms the plant.
If you are going to grow cannabis outdoors in plastic pots, make sure they are always a different colour (brown, white).
