Please check this out and give me any feedback you can think of. I have been doing a lot of reading and tokin

and have come up with this idea for a super stealth cabinet.
I am thinking about using a 250w HPS light for the flower area, but would really like to get a 400w HPS in there, but am worried about heat.

I will probably supplement the flower area with CFLs to help balance the light and maybe give it more lumens if I do go with the 250w. Here is the light I am thinking about

For the Veg area, I am thinking about 6 - CFLs (~30w ea)
For the vents I am thinking about a passive intake with a 6" duct blower

I plan on using the rigid duct work as I have heard that the flexible tubes will cause more CFM loss. I also plan on using a similar 4" duct blower with flex tubing for the HPS light.
Please let me know your thoughts/ideas on my venting, lighting, and odor control plans as I have tried to scour this site and get the best ideas together into this one stealth cab. I have borrowed ideas from a couple of those bad ass stealth fridges and some other ideas, but am trying to keep this thing as self contained and stealth as possible.
