What are the effects of green and far red?
Migro did a video showing the following spectrum and intensity measurements comparing above and below a leaf.
He found 10% Green and 50% Far red penetrated the leaf, and that 5% Green and 40% Far red reflected from the leaves.
UV causes plants to produce oils, antioxidant vitamins and flavonoids to protect themselves from the damaging effects of UV. These compounds produce the vibrant colors, smells and tastes of plants.

How many watts do I need per square foot of grow space?
You will want around 30-40 watts of actual wattage per square foot of grow space. Some LED grow lights require less, while others require more depending on the efficiency. It is best to follow the manufacturer's recommendation because all LED units are designed differently. See this article to learn more.
You shouldn't actually use wattage to determine how powerful of an LED grow light you need. Instead there are other factors that are more important, such as PPFD and footprint uniformity.
