I got some MH lightbulbs and they don't say if they are 4000K or 5500K, is there any way to tell the difference?? :oops:

I know (think???) that 5500K is better for veg, but I think that the MH Lightbulb is 4000K....

If it is 4000K, does it work good? Does it work at all? Is there any way I can complement with some CFL or HPS?

Please help, we are desperate :( :stoned: :cry: :x


Thanks :D


You can veg with a hps light which is around 2000k so I can't see having a light that is 4000K is going to be a problem.
