The range of Superoots Air-Pot Kits has been extended to include 12.5 litre, 20 litre and 25 litre sizes. In light of the success of the bigger 35litre and 45 litre Air-Pot Kits, and in response to customer demand, the Caledonian Tree Company designed and manufactured the three new sizes ready for potting this spring. Advanced orders of 200,000 Air-Pot kits in the 12.5 litre size - or 3 gallon, as it is called in the USA - have been made by Cherrylake Tree Farm in Florida for 2002. If the first year's production is a success, the nursery will steadily convert all its container activity to Superoots Air-Pots. Cherrylake already uses 15, 30 and 50 gallon Air-Pots.

The 20 litre Air-Pot Kit was introduced by request from a new British customer, whose initial trials suffered no losses. The nursery will be launching its new range in 2003.

Growers of large semi-mature trees and landscape companies who have to hold large trees above ground for summer planting are also delighted by the introduction of an Air-Pot 900mm deep (where previously the maximum was 600mm). This allows the largest rootballs to be wrapped in Air-Pot material, making containers with a capacity of 1200 - 5000 litre (plus).

All Superoots Air-Pots have been significantly improved, with a new process at the factory, which cuts a regular hole in the cones of the Air-Pot walls ensuring a consistent air-content in the container. It also makes the Air-Pot a much better looking product at the nursery. In order to form a 'reservoir' at the top of the Air-Pot and to prevent any unnecessary loss of water when irrigating, there are no holes in the top two rows of cones. And the holes at the base of the container are bigger to allow greater air circulation here where humidity can be greatest.

There are also two new fixings to choose from when buying Air-Pots, both of which can be mechanically or manually fitted: the bigger one is designed to assemble the heavier material, and the second smaller one is designed to assemble the lighter Air-Pot Kits. They improve the assembly process dramatically and make it child's play. Both are in Superoots green.
