I'm still a bit new to growing myself, but seeing as no one else has replied, here is my :twocents:.

You can use the 6500k blue spectrum lights for the entire vegging period but you will get much more rapid growth using a Grolux or MH lamp. I assume you are using CFL's to eliminate heat issues in a small veg space?

4 x 26w CFL's isn't going to be enough light for 10 plants imo, I think they would grow very slowly. I used 1 x 125 watt CFL for 2 plants during my 1st grow and got just over 2oz a plant. I have since increased this to 2 x 125w for my second grow and in the future I plant to increase this to 2 x 250watt to increase my plants yield. Basically, the more light the better.
