Done for now. Gonna grab some cable clamps at Lowe's today.
Beginning exploratory surgery for my air intake. This will snake under a bathtub and poke into the house in our laundry room. I plan on zig zagging the pipe to create a light block and cap the intake inside with a 1 way flap and a charcoal filter. Exhaust for now will be connected to a charcoal filter bucket and a hepa filter using a large Honeywell hepa filter fan to pull air out of the grow.
Got tons to go and several logistics to plan but so far so good.
