not tryin to rain on your parade or anything...
Looks like your doing a great job.
Just wanted to point out that you'd be better off not growing a plant with a 9' ceiling in mind.
Tell yourself you only have "x" amount of room to work with. thats going to be a true test of skill as you become better with each garden or harvest.
9' is way to much space to waste all that time growing when the best part of the plant will be the closest to the light. All the under growth, and low sites will be starving for light.
Hope you can make use of this.
