Jackie has now overgrown the middle bucket by 2-3" still under 22 watts with the the flowers starting to fill out a bit.

I am going to continue this journal, but put her under my 140w DIY LED lamp in the next few days. I will post one final photo in the buckets. I believe that I have shown what is possible with minimal lighting and I would not hesitate to continue flowering her if there was just a little bit more space. I am certain I could get a great GPW yield ratio if I could finish. Hope this has inspired a few of you.

I will get a much better yield under the 140w, but a much lower GPW ratio because the light is spread over a much larger area and will not be contained in the same way.

My Single 3W LED A-Train Grow I see so many baby plants vegged under big HID lights or like 5-6 or more 23w or larger CLFs or a 90-120W LED, 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 Rating: 5
