Gaz,
Orchid growing for all of us is a trial and error procedure. We learn as much as we can to give each genera what it wants within our own personal limitations of our environment. Many times we try to fit a "square peg into a round hole" and find it simply does not work that way with orchids.
In the end, we wind up with what we like and do the best we can to benefit our plants. Always keep your mind open to change and improvement, no matter what. We, as growers, have to learn to adapt too.
I think you will do just fine with your Cymbidiums if you keep in mind what they want and the problems you know you have to watch for. Good luck.
