I see so many baby plants vegged under big HID lights or like 5-6 or more 23w or larger CLFs, when that is hardly necessary. And then the same people talk about GPW... People did not believe the huge plant I vegged with a single 23w CFL, yet this is way more impressive. It is all about not wasting light. Here is my widdle 8" X 8" A-Train vegged under a single 3w cool white LED. Yes, one 3W light with nothing else. The hull wouldn't come off and it was nearly dead and I was ready to toss it, but it made a full recovery and is a happy camper. Think I am lying? A standard CFL radiates in almost a 360 degree radius. This is a 30 degree LED thus the beam is concentrated 12 times and since it has 50% more LPW, that is 18 times the concentration of a comparable CFL. Will probably flip in one more week. I am going to attempt to flower with an absolute minimum of watts and still get an acceptable harvest to see what is possible. I might have to go as high as 18w.
