Best Pot Size for Autoflowering Seeds

Best Pot Size for Autoflowering Seeds

Selecting the best pot sizes for your autoflower seeds is very important and could be tricky.  Here’s all you need to know to make an informed decision. 

Autoflower weed seeds are a great way to grow your marijuana, and they’re even better when you have the right pot size. If you don’t choose the right pot size, your plants won’t grow properly. This means they won’t produce enough quality buds for you to enjoy.

The size of the pot you choose will depend on several factors, including your budget and how much growing space you have. Your best bet is to start with a small pot and work your way up if necessary—you’ll need much less space if you’re starting with a 2-gallon pot than if you start with the one that’s 4 gallons in size.

Factors to Consider When Choosing autoflower seeds Pot Sizes


When choosing pot sizes for autoflowering cannabis plants, consider the root size and growth habit of your chosen strain. If you’re growing a plant with long roots, it can be hard to tell how much soil is needed. 

Choose a container that’s at least one size larger than the final root ball of your plant. This will allow room for growth without crowding out nutrients from the roots. You should also ensure that your plant has enough room to stretch out and develop its branches. If your plant is already too crowded, it may not be able to grow properly.


You should also consider how much space you have available for your plants. You can use a smaller pot if you plan to keep them indoors, but vice versa—if you live in an apartment or have limited growing space outdoors, you might want to choose a larger pot.


Drainage is a very important factor that affects the success of your autoflowering cannabis plants. If you don’t provide enough drainage, your plants will become root bound, which means they can’t grow normally.

Autoflowers are typically not as deep-rooted as regular seedlings, so they need to be cared for differently than other plants. To prevent root problems and encourage healthy growth, ensure your pot has holes in the bottom and around the rim so excess water can drain out easily.

Type of container

If you’re growing in a greenhouse or other large area, fabric pots will be easier on your plants because they don’t have to compete for nutrients and light. They’ll also be easier to water because there’s no risk of overflow when it rains. And if you need to move them around, they will be less likely to break.

On the other hand, if your space is limited and you want more control over how much light and nutrients your autoflower seeds plants get, then regular pots are probably better for you because they let air circulate them so that roots stay healthy.

Few large pots or several smaller ones

The bigger the pot, the more plants can be grown in it. But there are also disadvantages to growing in larger pots. For one, if you have a lot of plants and they’re all growing together, there’s less room for air circulation and ventilation. This can lead to problems with root rot, pests, and disease.

It also means that each plant has less space to grow than the smaller pots would allow. In some cases, this could mean lower yields or shorter harvests.

Pot Sizes for Growing Autoflowers

Small Containers

Small containers are also great for beginners who do not have a lot of space or want to start their indoor garden with a small investment. Also, Small containers have sizes of between 1.5 to 2.5 gallons in size. These containers can be used indoors or outdoors, depending on your region.

Small containers are perfect for growing just one plant like autoflower seeds, especially if you want to save space in your garden. They’ll also work well if you have a small space where you don’t have much room for gardening but still want some control over your cannabis plants’ development.

Large Containers

Large containers are best for growers who want to grow multiple strains simultaneously. These large containers hold enough nutrients to support several plants and provide plenty of room for each plant to grow naturally. These pots are usually between 2 and 4 gallons in size, depending on the strain. 

They can be filled with soil or hydro, depending on your preference. Containers this size might be too large for small gardens and indoor gardens, but they are great for those with bigger gardens or more indoor space!


It comes down to the grower and their process. Some growers can get away with smaller container sizes, while others need to go all out to guarantee they have enough height to control light exposure. If you’re unsure, try to start on the smaller side and work your way up. Mistakes can be made by using a container that is too large, but it’s impossible to take a container that is too small and make it bigger without a major impact on the space you have in your grow area. It takes a lot of time and energy to nurture young plants/seedlings, so plan ahead. To purchase the best autoflower cannabis seeds for your garden, check out the Herbies head shop
