The more light the better?

Hi. I´ve just finished my PC Grow Cabinet, and are now waiting for my two AK-47 Autoflower&feminized seeds to germinate.
I´ve got two 35W CFL 6400K bulbs for veg-fase and two 23W CFL 2700K-bulbs for flowering.
My plan was to just use 2 bulbs at a time, but I have the possibility to use 4.

Will it be better for my plants to have 2 bulbs with 6400K, and in addition to that have for instance 46w 2700k bulbs and one 11w led 2800k?
And when I switch to flowering, replace the 6400k ones with some energy saving bulbs that have got 2700K?

Is it the more light the better, or is it important that the plants get mostly light in 6400 kelvin first?
Looking forward to hear from you guys! And by the way, I will have a journal here :) Looking forward to show you guys. It´s my first grow ever!

The peak for photosynthesis in veg is at 5500°K and for flower at 2100°K. The curve drops off sharply on either side of these numbers. The color of the light is far less important than the quantity of light and it's difficult to give your plants too much light as long as the temperature is under control. On average, cannabis likes temps in the mid 70s.

OK, I got 4 fans so I don´t think temperature will be a problem. In fact, I´m testing it today after I buy some batteries for the thermometer.
Well, then I´m going all in on the bulbs :) To give them all the light I got. OK, 75 fahrenheit is 23 celcius. Sounds like something that will do just fine.

Run bigger in flower or your plants will tell you to fuck off. Theres no reason that you want the peak light hitting them to be in veg. Theres no money in vegging plants. Remember that. Run every watt possible in flower from what you have and the what the temps let you max out at. Cfls are forgiving if theres enough room from the leafs.

Ah, ok. So there should be an increase in lightning when they flower?
So in veg, i should just use my two 6400K-bulbs, and in flower use all the 2700K + the 6400K?:)

General rule for HID lights is 150w per plant, then 50w more per additional plant. To do a through and through grow with cfl's, i would just say use a shit load. Cant really have too many. Use majority cool spectrum in veg, and warm spectrum in flower. Or just but a crap load of each and use them all from a-z.
