After this there will be different slide shows. In this case, you should think about it's environment. Aldrovanda lives in and under water so you should use the type of light that people who grow plants under water use. The CP part of the equation is more related to the type of chemicals it likes in it's environment. It doesn't have to do with them being CP's.
Some plants are more specific too large for tubes.
I personally don't use just cool-white tubes, but mix grow lights and cool white. I feel that I get better results, even if the plants don't feel anything, since the grow bulbs have a more red and blue while the cool-whites are more yellow. I have tried watering everyday with refrigerated purified water, using a pump to circulate water to the root, but they always end up dead. I once read about a fellow CPer using an ice cooler to grow hers in. Thanks for any input.
