Lightweight vs Heavy-Duty Planters
Smaller pots are usually ideal for those who move or reposition plants frequently, and for those who have to move in different weather conditions. The source also points out that they can be beneficial for smaller plants that don't need a lot of root space. However, lightweight pottery can be more fragile, and when large, they can be easily toppled over. Pots that are tossed by the wind with such force are easily knocked over and may be made of poor quality material. Heavy pots are usually more stable and durable, so they are best used for giant plants or plants that are placed in uncovered areas. They retain moisture and heat well, which promotes healthy plant growth. If you're looking for pots like these, I recommend checking out https://idealistplanters.co.uk/extra-large-planter-pots/. There are also several pots there made of other materials that can match the surroundings to some degree.
Lightweight pots are certainly easy to move around, especially if you change the location of your plants often. But I've also noticed that large heavy pots are more stable, and if you don't need to move them around all the time, that's ideal. Heavy pots tend to be more durable, but they are harder to move, so it's worth considering your goals and needs when choosing.
