SIZE OF POTS FOR CANNABIS PLANTS
Choosing a plant pot is an important but often overlooked task. They come in all shapes and sizes that are all going to effect the way your plant grows in some subtle way.

Happy cannabis roots want…

Moist at all times — roots die when they dry out! Good watering practices combined with a great growing medium will make sure your roots never dry out

Oxygen — your roots “breathe” oxygen, so one of the best things you can do for them is make sure they always have access to plenty of oxygen — more oxygen to the roots = faster growth

Nutrients — your roots “find” nutrients at the roots, and then deliver them to the rest of the plant, so making sure your plant has easy access to nutrients will help your plants thrive and make buds

pH Management — Some nutrients are sensitive to the pH of their environment. When exposed to the wrong pH, the molecular form of these nutrients actually changes.

POT SIZE MATTERS!
Did you give your plant a 2, 3, 4 or 5 gallon pot, or a 10 gallon pot? The bigger the pot, the bigger the plant. Lighting is another key ingredient to increasing your plant yields. If you grow with a cheap LED Light, you’ll diminish the plant’s yield potential. You’ll want to grow with a high quality LED grow light to get the most amount of yield per plant indoors.

With all that said about indoor plant yields, home growers who grow marijuana plants indoors in grow tents may yield from 1–5 ounces per cannabis plant, with a sweet spot of 2–4 ounces per plant. Honestly it depends on the above mentioned gardening and genetic factors, but this gives you a realistic snapshot of your cannabis yield potential.

The pot sizes needed is going to depend on the length of vegetation. You can base your expectations on the table above and use this guide to determine your transplant strategy and final container sizes. We recommend fabric pots for all containers

  • 0-week vegetation: Start plants in 1-gallon pots, no transplanting.
  • 1-week vegetation: Start and stay in 1-gallon or start plants in ½ gallon fabric pots and transplant to 2-gallon at the flip.
  • 2-week vegetation: Start plants in ½ gallon fabric pots, transplant to 2-gallon 3 days before the flip.
  • 3-week vegetation: Start plants in ½ gallon fabric pots, transplant to 2 or 3-gallon around day 18.
  • 4-week vegetation: Start plants in ½ gallon pots, transplant to 3-gallon around day 18.

A relatively new innovation in container gardening, fabric grow pots offer many benefits when it comes to building healthy root systems. Roots in fabric pots grow to the outer edges and attempt to bypass the porous fabric wall. Instead, they are cut back, allowing new growth to occur. This process, called “air-pruning,” results in denser root composition which promotes healthy growth and development.

Promotes dense, healthy root systems

Increased airflow to the roots

Excellent drainage ideal for carefully-maintained gardens

Requires more attention and maintenance as the pots dry out quickly (Note: you can use larger pots to help slow dry-out.)

Flimsy structure can make plant support challenging

We all know that the better the roots the better the plant. Well look at this pot. This will give you heavy roots for your tomatoes , pumpkins, and any other plant you want great roots on. The Accelerator air root pruning system is a natural way to help grow a better tree with a stronger root structure from propagation to final planting in the ground. Utilizing a patented root enhancement technology, Accelerator containers produce much larger trees in the same time as conventional container products, at a cost-per-tree that is less than traditional methods.

Pot and Container Sizes for Growing Vegetable Crops

Pots and containers for growing vegetables and herbs on patios, balconies and roof tops must be large enough for the crop to mature. A container must hold the soil and moisture that deliver nutrients to growing plants allowing them to leaf, flower, and fruit. The pot must be large enough to accommodate the plant’s roots. And a pot should be large enough that the height and weight of the above ground growth of the plant does not tip the container.

Some plants are small enough that you can grow more than one plant in a container; other plants grow so large that you would not want to grow more than a single plant in a container.

Soil depth of at least 8 inches/ 20 cm will hold sufficient soil, nutrients, and moisture to support a good yield from almost every vegetable and herb grown in a container. (Expect to water two or three times per week.) Smaller containers holding less soil may require more frequent watering and fertilizing.

Containers Must Be Well Drained

Good drainage is essential when growing plants in containers. Containers less than 10 inches/25 cm in diameter should have a hole ½ inch/ 1.2 cm in diameter to provide good drainage. Containers greater than 10 inches in diameter need two to four holes.

Pots and containers for growing vegetables and herbs on patios, balconies and roof tops must be large enough for the crop to mature. A container must hold
