18/6, 24/0, or any other combo - best way to veg?

ive had my plants in veg at 24/7, just because im impatient and was hoping more light=more growth, which some people say is true, some dont. some period of darkness just seems more natural and one might think better, but i cant decide. should i go down to 18/6 or maybe 20/4?

Experiments have proven that 24hrs is better in veg, although I have tweeked with my fertilizers to compensate. The Limiting Factors are=Light, CO2, Temp, Air, Water, Fertilizer, Containers...Word.

+1 for 24/0
