Root pruning pot 21Ltr like Rocket pots - air prune roots for root mass

Pot dimensions when flat packed are: 100 x 33 x 5cm as well as 5cm x 33 x 33cm for the base.

Why Use Air Pruning pots? Well air pruning pots have many advantages

• Excellent drainage - more difficult to overwater
• Larger root mass - while roots grow arond and around in a plastic or ceramic pot, the air at the edge of the fabric causes a root tip to dry out, and die off. Just like pruning the top of the plants, the roots will branch into many smaller roots because of "air-pruning". The mass is larger and made of more smaller more effective roots.
• Higher oxygenation to the roots
• Easy to store when not in use
• encourages aerobic bacteria/microbes
• Evaporation may reduce root zone temperatures (its a plus/negative sort of thing as the pot will dry out more)

Its definitely worth running a side by side comparison. The only negative is

• due to evaporation around the outside of the pot, these pots may need to be watered more often than a solid sided pot of the same size.
  • If you can't water more than you do already, going up one size of pot is a solution or leaving the pot in a saucer/bucket that allows the base to be in contact with some solution to suck up as it dries out.
