I looked it up on Wiki.
It says that "Bright sunlight provides illumination of approximately 100,000 candella per square meter at the Earth's surface." It then goes on to state "a uniform 1 candela source emits 12.6 lumens."
So, if I do the math... 100,000 X 12.6 = 1,260,000.
One million, two hundred sixty thousand lumens per square meter.
Hmmmmmmmmmmmmmmmm.....
dooobster Reviewed by dooobster on . Northern California - Small Rooftop Grow i planted 4 seeds on 4/20 and 8 more the weekend after. the first seeds that were planted all sprouted and kept a healty look, so i kept them all. out of the eight that were planted the next weekend, 6 sprouted, but one looked deformed, so i decided to just get rid of that one early. if you notice, there are two plants that have been topped, and here is the story behind that... i was planning on moving the plants to an easier location, so its less work to water them and keep up with them. so Rating: 5
