We don’t use solid plastic pots.
Instead, we use Fabric Pots or Air Pots. Because they let more oxygen reach the roots … and that makes them grow better.
Fabric pots have air-penetrable material.
Air Pots have small holes in them.
Both of these pots work well.
How many Plants?
You could fill your space with several small pots or 1 big one.
Its not clear which method bring a bigger yield.
But many people prefer having several plants.
The minimum size for a pot with soil is 3 Gallons.
