Did you notice I actually provided an answer to the OP...along with the reasoning? That is helpful information. It doesn't take more than a few minutes for the un-initiated to see that the majority of larger grows use HPS. Obviously CFL would not be a good choice in that case.
I will point out to you that when you start to get down to the lower wattage, HPS efficiency starts to decline. Grams per watt is not much different at 150 watts and below regardless of HPS or CFL. People complain about bud density, but the weight is about the same. It is about .60 - .65 grams per watt.
Big words more important?...No, if a person can understand the technical aspects...GREAT! If not, then no big deal. There are lots of different types of people who read these forums. I post info for everyone. Has nothing to to do with 'BIG' words.
