Who has the Club PAR Meter? I would like to use it this weekend. I have replaced my 250 watt MH bulbs with two different brands. I am interested in the readings they give. I have a Phoenix 14k and a 20k Ushio. I am unable to tell any difference between the two, the color is very close and it is way too early to see any growth difference.
