Air Root Elevator is specially designed for coir bags. They are robust and resistant thanks to its material and its UV treatment. It allows a greater air flow around the base of the holder and allows increased luminosity, which, in the drainage area, leads to self-induced root pruning. It also improves drainage.
Its light weight makes it easy to handle when in use. Avoid dead areas in the centre of the root ball, common when paving stones or bricks are used. They are stackable pieces, which allows for better storage when they are not being used.
