What Size Pot is Ideal for Autoflowering Cannabis?

For most cannabis growers, there are two common types of cannabis plants: photoperiod and autoflowering. Photoperiod cannabis relies on light cycles to initiate flowering, while autoflowering cannabis will flower without any change in light cycles.

When it comes to growing autoflowering cannabis, selecting the right size pot is important for success. But which size pot do you need?

Best Pot Sizes for Autoflowering Cannabis

When it comes to autoflowering cannabis, the size of your pot will depend on the size of your desired yield. Generally, you should use larger pots if your goal is to maximize yields. Here are some of the best pot sizes for autoflowering cannabis:

  • 2-3 gallon pot: This is a great option for smaller gardens, as it will produce yields of about 3-4 ounces.
  • 5 gallon pot: This pot size will produce yields of 6-8 ounces.
  • 7 gallon pot: This size pot will produce yields of 8-10 ounces.
  • 15 gallon pot: For larger gardens, this pot size will produce yields of 12-15 ounces or more.

Other Important Factors to Consider

In addition to choosing the right size pot, there are other factors you should consider when selecting the best growing medium for autoflowering cannabis.

In terms of nutrition, autoflowering cannabis does best when it is provided with ample amounts of calcium, magnesium, and nitrogen. You should also keep the soil slightly acidic (around 6 pH).

Finally, you should ensure that the growing medium is well-aerated. Autoflowering cannabis needs plenty of oxygen to grow, and poor aeration can lead to stunted growth.


Choosing the right size pot for autoflowering cannabis is essential for producing the best yields. Generally speaking, larger pots will produce bigger yields. But aside from size, there are other factors to consider such as aeration, nutrition, and pH.

By taking all these factors into account, you can ensure that your autoflowering cannabis plants get the perfect environment to thrive.
