Formulated to provide a stable pH, Canna Aqua is specifically designed to work in re-circulating hydroponic systems such as NFT tanks and flood and drain set-ups.
Because the plants are in constant contact with the nutrient solution, and not all nutrients are absorbed at the same rate, the composition of the solution will change over time.
Canna Aqua has been designed to allow for this and also contains buffering agents to maintain the pH levels once they have been set. It also works well with both hard and soft water.
As with all Canna nutrients there can be a tendency for plants to ‘lock-up’ if you haven’t got everything right, but overall this is a great nutrient and a popular choice.
