Default best hid's for plant growth

What are the best hid's for plant growth. Most supplyers over here recommend Sodium which I have been using without much success. I keep getting told that my plants need more light: I'm no expert, but the plants which I am growing do not need 30,000 lux. I feel that they would grow much better under metal halide lamps, but I am reluctant to spend any more money until I am sure. I have already bought 250, 400, 600 watt systems on the advice of 'experts' in the UK.

metal halide is favored by many indoor growers because of its broad spectrum of white light and is ideal for seedlings and vegetative growth and then switch to high pressure sodium for flowering because hps has a light spectrum in the red, orange and yellow range. A combination of the two will give your plants the full light spectrum they need for healthy growth.
