Is dennerle perfect plant system set any good?

Hi,

Just bought a dennerle CO2 system and it came with a set of fertiliser called "perfect plant system set".
Is that any good? Anyone with good or bad experience of these products?
Thanks

It works but it is relatively expensive, complicated to use compared with all-in-one products, and isn't suitable for high-energy systems with big nutrient demands.
