150 W cfl bulb

Im currently only using one 150 w cfl bulb for flowering cycle, and was wondering if i should increase the amount of light during the budding stage to increase yield?

Was thinking of getting a 300 watt single cfl bulb from home depot over it?

Veg stage is when you can use cfl's, but for flowering (budding) you should use a HPS bulb. You will have better results in the end, how many plants do you have currently ? If you have 1 plant go with 150w hps, 2 - 250w hps , 3-5 400w hps.
