Hey J,
What up? ! Good to see things moving along faster!
I've only done business with BGHydro (Better Grow Hydro), and they're excellent. So I don't know as to lower prices/bargains. But I will recommend BGHydro dude, very very good.
As to the $1600, I think that's enough money. How big is the room? How many plants?

Interesting J. Hey, I was thinking: If I could change a couple of thing of my setup, it would definitely be the fans. I would buy good, high quality fans. Daytons or Fantechs or something.

Good to see you man,
