Choosing a suitable vessel to grow your plant in is a delicate balance. It can affect the overall health, amount, and quality of the weed you cultivate.

Size Matters

When planting greenery, the growing container’s size dictates the final dimensions of the adult shrub. The pot houses the plant’s roots, which must have ample space, drainage, and airflow for healthy development.

The roots’ depth and width determine the height and width of the leaves and stem.

If your container is too small, your roots will quickly use all of its available space, stressing the plant. Using a large vessel wastes growing medium and nutrients and takes up unnecessary space that additional crops could occupy.

These points indicate the importance of using the correct pot volume and that size does matter when growing cannabis.

Pot Sizes for Autoflowers

Common strains of marijuana plants are often transplanted into bigger pots as they grow. Most have containers that have been changed at least once in their life cycles. Autoflower cannabis is a little fussier. 

While the seeds are easy to grow and very resilient,  autoflower prefers to stay in the same vessel for the duration of its life. Transplanting autoflowers decreases their bud production, and nobody wants that.

Another thought to keep in mind when selecting a pot size for autoflower cannabis is your growing setup. Making a choice based on your available resources is the best way to ensure thriving plants and an optimum harvest.
