Ok so things got really busy at work and I haven't been able to update much, so I will fill you guys in on what's been taking place.
I decided on just going with a small ac unit with a built-in de-humidfier for simplicity and isolation from the ac of the house, I still need to determine where I will route the drain.
There was also an issue with the tank bracing that bothered me from the start, the bracing that was installed was positioned on either side of the overflow and caused a bit of a shadow with my halide suspended over it, here is a top down shot of the tank:
What I ended up doing was removing the plastic trim along with the center braces to install common euro-bracing which allows me to place the pendants over the tank at spacing that does not cause them to sit over any braces. I will post pics when it is completed.
My buddy who is a construction superintendent finally freed up his calendar enough to come by last night and scope the entire project out:rollface: "Piece of cake" he said

So the plan for this weekend is to get the opening framed out the walls framed and dry-walled and the stand built. We are also gonna be pulling 12-3 romex to supply (2) 20amp outlets one at the top of the wall and one at the bottom. My lights will be plugged into the top circuit and the rest of the equipment like pumps etc will utilize the bottom.
Looks like I'll be missing the monthly FRAG meet!
