I don't think the blurry pics of average weed is very good advertising. If I was the marketing manager I would grow some nice plants under HID's and then take a pic with the mars hydro over them.
I accidentally got some good results in veg with a Walmart led shop light. The plants under that led got thicker stronger stems and branches than the plants under the 400mh.. I plan to do more testing with it. Led's may be ideal for vegging for all I know.
