They will pick up the white and blue light and will gradually tune themselves to pick up the full spectrum of the light.. so it will appear that your lights are changing colour... but in actuality.. its just your eyes adusting to the VERY bright light... Keep in mind.. that 600W bulb puts out 10X+ more light than a standard 60W bulb.. so your eyes just arent used to seeing that drastic of a difference in light... Doesnt sound like there is a problem imo :-)

Well said. don't look too long, it can be like looking at a welding rod burning.
LOC NAR on probation Reviewed by LOC NAR on probation on . 600w HPS Lighting Question. Total Newbie so please be gentle Hi to all the Cannabis crew. This is my first ever post for my first ever grow. Just a quick Question. When my Light first starts it emits a nice bright ice looking white around my grow tent. Temp inside tent at start up is not far off 20 degrees c. When I sometimes have a quick look in by unziping the doors i can clearly see that its more of a amber/red glow. Tent Temp is normally in the range of around 25 to 28 degress C. If i then stand there with the doors 1/4 way unzipped it will then Rating: 5
