Both true and false.. (low K is better for growth than high K but some people think high K brings out colors better), Besides this is a thread about Bob's cheap lights he found that actually look decent. If you want to know more do a search on light spectrum, lots and lots of good information
Looks good Bob.
Oh and sense Bob didn't pick it up "spectrum" is already a plural so you don't need the "S" on the end..
