figured id actually answer the second part of your question
since no one else chimed in
the amount of lst depends on your amount of vertical space , canopy level , and probably alot more that my stoner ass cant think of
most of all it depends on YOU
if your skill level/ experience with it is low then start simple just tie some branches down
then progress to tying the main stalk at around 5-7 nodes tie a loop around the main stalk at just above the 3rd node
poke a hole in the rim of the pot and and start to pull it down then lst the branches even them up and pull them down
more advanced would be tying the main stalk down around the edge of the pot
