HOW DO I HARVEST MY PLANT???

[Skarlet]

Then hang the bud upside down attached to a string but can I do it in my closet? and I must keep it DARK? Right?

You can do it in your closet. Keeping it dark is simply a recommendation.

Why do we have to do that? Like what does it do to the bud? Make it more potent?

The poster above me pretty much answered it correctly. Two things happen while the buds are in the jar. First, it allows the moisture that is deep inside of the buds to even out with the extreme dryness of the surface of the bud. Essentially, the water from inside the bud will move into the air inside of the jar and then be absorbed by the surface of the bud. You air out the jars daily to remove excessive moisture from the air inside of the jars. If you didn't do this process inside of a jar then your buds would be so dry after two weeks that they would crumble to a powder. The second reason that you let them 'cure' for two weeks is so that the plant has a chance to convert the chlorophyll inside of the buds into something else.

Pull a bud off of your plant and quick dry it in your microwave for 30 seconds or so until it is dry. Stick it in a bowl and smoke it. Notice that nasty fresh burning grass that you taste? Well that doesn't happen with a properly 'cured' bud. It is all about flavour, not potency.
