WTF do these terms mean??!?

Ok, I have been on this forum for a short time, quite active and trying to learn as much as I can, so I will get my balls out and just ask..

What the hell do these stand for...

SoG - ..... Sea of Green?
SCROG -
LSD (Growing wise, I know of the drug)


+Rep, and if you know any others, I would appreciate the input!

sea of green
screen of green
a type of plant unless you meant lst which is low stress training.
Keep the rep.
