Does flowering under CFLs take longer?

[Italiano715]

I know many different factors can have an impact on the outcome of your crop but hypothetically, if two different crops with virtually identical environments except one has a 400w HPS and the other has equal wattage of CFL's, would the crop under the CFL's take longer to mature?

When using CFL's it doesn't have the same lumen output as a HPS, so you would virtually have to use more wattage from the CFL's.

Basically 250W of CFLs is not the same as 250W HPS...The HPS has a lot more lumen output then the CFLs, plus the HPS penetrates further into the canopy usually resulting in bigger buds, I.E. all other conditions are met.
