On average, doubling
pot size allowed
plants to grow 43% larger. ... To understand the
pot size effect, the scientists looked at various aspects of the
plants'
growth. They found that the
plants in smaller
pots grew more slowly because of a decreased rate of photosynthesis.Jul
With auto flowering plants it’s not that easy to chose the pot size because you need to think not only about the time how long will your plant live, but you need to also think about the
size of the plant and how big you want it to get. Most people choose auto-flowering strains because their growing space is limited and they can’t grow plants that stretch 1 or 2 meters (3,2 or 6,5 feet) in height and pot size can greatly affect the plants height. If you plant your autoflower cannabis seed in a small container like a “Dixie cup” then it will stay short because it will become pot bound (root bound) fast and that will stress the plant slowing down the growth.
Using too small a pot
This is a common mistake that often can often lead to disappointment for the grower, who may end up harvesting a plant that's only 20 or 30 centimetres high, with a much lower yield than expected. The explanation is simple; When the seed germinates, its
main taproot develops downwards in a straight line. As soon as the root tip encounters a barrier (the base of the flowerpot) which stops it growing any further, the aerial parts of the plant will cease development and soon after initiate flowering, with a much smaller structure than if it had been in a larger pot or planted in full soil, which is where these varieties offer the best performance.
To avoid this unfortunate phenomenon, we need simply use good-sized
plant pots from the start, with a minimum capacity of 7L for indoor plants and 15L outdoors. This way we make sure that the plant will reach a considerable height before flowering, and be able to deliver the yields we expect
Just saying a tiny bit of info I found proving what I said earlier
