Here are some more pictures that I had to leave out of the guide due to limited space:
The foot-candle is equal to one lumen per square foot
. Lumen is a measure of the perceived power of light. Full, unobstructed sunlight has an intensity of approximately 10,000 foot-candles.

The credit goes to CaliGrower who created these charts in the first place. The charts are in imperial units so those more familiar with the metric system will have to use an online converter.
Also, here is a more detalied picture on the male and female flowers, as well as how they develop:
Note here that somtimes there is undifferntiated vegetative growth at the nodes that can be mistaken for male flowers, so when you are sexing you plants, make sure that you wait long enough to be sure before removing any plant from the grow. The undifferentiated and staminate primordia can resemble each other in the early stages of development.
One thing that is good to keep in mind is that if you see more than one distinct "pod" forming at the node, you are most likely looking at a male plant becuase females produce only one elongated calyx at each node. If the preflower starts splitting up into several "pods" you are looking at a male flower.
