Is using Philips Daylight Deluxe and Philips Cool White a good combo for veg?
Philips Daylight Deluxe are 6500k and the Philips Cool Whites 4100K
For the vegetative phase you would want to use 6500K bulbs. When you switch to flowering you would be ahead to hunt up bulbs with a color temperature as close to 2700K as possible. These are sometimes referred to as being "warm white" I believe. You would also be fine with a ratio of 25% 6500K and 75% 2700K.
