cfl question

allright ive read around a lil bit about the clf and i have made my own little setup and have notices some are more yellow and some are almost blue. is one better then the other? or should i try to use both? thx for any help

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

Yes, by law they have to. blue is Daylight, red is Warm White. DO NOT buy cool white they are no good.

oh ic thanks guys

ok i got afloresent65w bulb thats 4100k is this a good color as far as cfl or lor should i take it back and get a 2700. im using themvegging

6500k for vegging is ideal, 6000k can be used though...

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.

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.
