you want the bluer ones for veg stage and redish ones for flowering stage. its on a kelvin scale cfls are easy to find 2700K for your redish ones and 6500K for your blueish ones

or both for flowering (you want to give them as much light as you can then)

take it back while you still can, 2700k is MUCH better, once you go over 3000 it really loses effectiveness, you want either really blue or really orange, not in between. Since its veg you should actually use 6500k like above ^^^ guy said, but if 2700k is all they have its better than the 4100. I used 2700 for veg and it didnt turn out too bad.

i agree 98% but if you cant find anything else the 4100k can be used for a veg. its slow but i used them for the first few weeks of my grow now untill i could find what i needed

ya actually I have heard of people using them and it working but lets say if you had a 100 watt 4,100k and a 100 watt 6,500k growing a plant side by side the 6,500k would be bigger, stronger, bushier, just all around better.
