1.What Size Pots For Cannabis?
Assuming you’re growing indoors, the size of your pots will be determined by the style of grow setup you’re using. For example, in a Sea of Green (SOG) setup, you’ll use many small pots to keep your plants short and uniform. In a Screen of Green (SCROG) setup, you’ll use fewer, larger pots so your plants can grow tall and fill out the screen. And in a Centralized System (hydroponics), you might use one big reservoir for all your plants.
The size of your pots will also be determined by how big your plants will get. If you’re growing dwarf or auto-flowering strains, you’ll need smaller pots. But if you’re growing monster indicas or Sativas, you’ll need larger ones. A good rule of thumb is that 1 gallon (3.8L) of soil is enough for a dwarf plant, 2-5 gallons (7.6-19L) for an average plant, and 5+ gallons (19+L) for a large plant. But remember that these are just guidelines! Some growers use larger or smaller pots with great success.
2.Why Does Size Matter?
As with most things cannabis related, the average consumer is left confused when it comes to purchasing a pot. Flower pot size is important, but it isn’t rocket science. The main concern should be how many plants you want to grow and how big you want them to get. Let’s take a look at some basics that will help you understand why size matters when it comes to flower pots.
Plants need room to grow. Just like people, they need space to stretch their limbs and roots. If you’re growing just one plant, you’ll need a pot that’s at least 3-5 gallons in size. If you’re looking to grow multiple plants, you’ll need a larger pot that can accommodate all of them.
The type of soil you use also plays a role in how big your pot should be. If you’re using a dense soil mix, you won’t need as much space for roots as you would if you were using a lighter mix. This is because dense soil holds more water and nutrients, so the roots don’t have to spread out as much in order to get what they need.
Finally, the size of your pot will also dictate how often you need to water your plants. Smaller pots will dry out more quickly than larger ones, so if you’re using a small pot, you’ll need to water your plant more often. On the other hand, if you’re using a large pot, you can water your plant less often because the soil will retain moisture for longer periods of time.

How big should my cannabis pot be?
The size of the pot will determine how large your plant’s root system can grow. A bigger pot means a bigger root system, which means your plant will be able to take up more water and nutrients. This is important because a healthy root system is the foundation of a healthy plant.
The general rule of thumb is to choose a pot that is 2-5 gallons in size. But there are some things you need to keep in mind when making your decision.
4.What If I Don’t Have The Right Size Pot?
You can always go up in size, just not down. So, if you’re questioning whether a 12″ plant will fit in an 18″ pot, the answer is yes. But, if you’re questioning whether an 18″ plant will fit in a 12″ pot, the answer is no. Generally speaking, you want your Cannabis plant to have about 2-4 gallons of space per foot of height. So, a 12″ cannabis plant should have a 24-60 gallon container.
5.What About Soil Volume?
Different soil types have different densities, which means that not all soils will expand the same way when they are wet. This is something you need to take into consideration when deciding on the size of your pot. If you’re using a soil that doesn’t expand much, you can get away with a smaller pot. If you’re using a soil that expands a lot, you need to go with a larger pot.
6.What About Drainage?
The critical thing to understand about drainage is that roots need air as well as water. If the roots are waterlogged, they will suffocate and die. Most plants need about a one-to-one ratio of water to air by volume in the root zone. So, if you have a plant that is using a gallon of water per day, you need to have at least a gallon of air space in the root zone for proper drainage. Of course, more is better.
To provide adequate drainage, most potting mixes contain some amount of perlite or vermiculite. These materials are relatively inert and do not break down over time like other organic materials in the mix. They also have a large internal surface area that allows them to hold onto lots of water but still drain well.
7.What About Watering?
While you can water your cannabis plants with just about any type of water, the quality of the water does matter. While rainwater or distilled water is ideal, most people simply use tap water. If you do use tap water, it’s a good idea to let it sit for 24 hours before using it on your plants. This will allow any chlorine in the water to dissipate.
8.What About Fertilizing?
cannabis plants need food – just like any other living thing. They take in nutrients from the soil and use them to grow. However, even the best quality soil will eventually become depleted of these essential nutrients. That’s why it’s important to fertilize your plants on a regular basis.
There are many different types of fertilizers available on the market, but not all of them are created equal. When choosing a fertilizer for your cannabis plants you should look for one that is high in nitrogen, phosphorus, and potassium – otherwise known as NPK. These are the three essential nutrients that your plants need in order to thrive.
You can find NPK ratios on the label of most fertilizers. A ratio of 10-10-10 is ideal, but anything close to that will work well. If you can’t find a fertilizer with an NPK ratio on the label, you can always ask the store clerk for help.
Once you’ve chosen a fertilizer, it’s important to follow the directions on the label carefully. Over-fertilizing your plants can be just as harmful as under-fertilizing them. Once you’ve determined how much fertilizer to use, you can either mix it into the soil before planting or add it to the water when you water your plants.
9.What About Lighting?
In terms of lighting, you will need approximately 40-60 watts of light per square foot. This can be either fluorescent or LED grow lights Be sure to get a light that emits in the correct color spectrum for photosynthesis (blue and red wavelengths). You should also get a light with a timer so you can have it on for 12 hours a day and off for 12 hours. This will mimic the natural day/night cycle and help your plants stay healthy.
10.What About Airflow?
Of course, you need to take into account the amount of space that you have available when deciding on pots. But, another factor to keep in mind is airflow. If you do not have proper airflow around your plants, they will not thrive. Make sure that you have plenty of room for air to circulate around each plant.
