Compact Fluorescent lights are great for starting cuttings or seeds. If used as a source of supplemental lighting, they are very effective for larger plants. Warm bulbs are (2700k) are best for general growth and flowering. Cool bulbs (6500k) are best for seedling, cloning and vegetative growth. They will work start to finish but the plant will be lanky with large node spacing.

HPS with Hortilux bulb is good for vegetation and flower. Not good for seedlings and clones to root.
