Well, I may be incorrect but this what ive known, I prefer to use a Metal Halide for the vegging, its the supposed right spectrum of light I believe, for your flowering stage, your going to want to use a high pressure sodium.

Derby Reviewed by Derby on . setup with cfl's hi i have 5 seedlings, 1 is a week old, lightened with 2 X 23w cfl (100w equivalent) soft white, and i have one 23w cfl for the other 4 which are only 2 days old. is it enough, would getting another 23w cfl for my one week old one be too much, or not even enough. is it better to use more 23w cfl or buy just one 100 or 125w cfl. Is it even possible for a plant to get too much light (lumen) thank you guys Rating: 5
