I cannot find his colour temp anywhere I suppose is blue,dunno.
Any ideas?
Thanks

nope the colored bulb does not help anything. just use the regular cfl's

Another user on the forum (cerebralvibrator) pointed me in the direction of this online store;

I purchased the 30w (150) cfls (incase you are wondering)

You have the right in the colour (blue'ish for veg and red'ish for flower) but its actually measured in Kelvins (colour temp).

Daylight being the blue
6400k
Warm White being red
2500k

I have an hps and mh for my veg/flowering (cfl for mothers), but after reading i think its better to have a mixture of bulbs giving it a wider spectrum...maybe something like
During veg
5 blue 2 red
Duing flower
5 red 2 blue

if that makes sense...you should have a read in the clf section...lots of great posts!

thanks for the reply guys I knew that but I was just curiois to know what coulor temp was actually that specific light ,thank you very much

you want cfl`s that put out light sprectum in the 6500k for the veg. stage and 2700k for the flower stage..

thanks for confirming pal

Yo, I can't seem to find any 6500k cfls. I'm trying to avoid having to go to a hydro store as they be price gauging, but Home depot and Walmart only seem to have 2700k and if they do have 6500k it does'nt say so on the box. Anybody got an economical solution on where to get 2700k cfls would be greatly appreciated.

here is a chart for ct it might help.
Color Temperature (CT) - Color temperature, which is measured in Kelvin, indicates whether a lamp has a warm, midrange or cool color appearance. "Warm" light sources have a low color temperature (2000-3000K) and feature more light in the red/orange/yellow range. Light with a higher color temperature (>5000K) features more blue light and is referred to as "cool."

I use the 100w and 80w cfl's. But those use a balist fixture. some say they have found the 42w in 6500k but I haven't benn able to. I have one plant under 1 100w cfl. it might be getting a little side light from the 80w but not much. the tube ligh you can see has never run on this plant.

Appreciate the info...yeah I'ma have to bite the bullet and go get raped at a dro store.
