what is the best type of bulb to use for plants with 2-25 Watt lights?

your question is a little too vague. What is the tank tank size u r planning to use.. is it a low tech or high approach. Do you plan to inject CO2? Substrate? which one do you plan to use.... which plants.... some plants require a rich substrate to flourish.

Later!

You can basically use any brand that you want as long as the K rating is between 5500k-10000K, with the 6500k/6700k being most commonly found/used.
