Thanks TinyToon....:thumbsup:

But i think i did ask the question in a wrong way....
I meant to ask if a 4000k light, in general(veg and flower), is any good for growing pot...i have read somewhere that the 4k lights are in that spectrum which the plants can't absorb....basically the plant can't use that wavelength - it's not in the red(flower) or in the blue(veg) spectrum....it's in-between....

So, can i use a 4000k light, or is it useless - because the plant can't absorb it for photosynthesis??
