Im not sure what size scrubber you should use. I would ask your hydroponic store. The one I use is good for upto 40 1000w lights. Its the biggest one i could find. It works great for killing smell. Cant smell a thing. Using a pilot light will give off Co2 while your lights are off. You dont want to give your plants Co2 while your plants are in the dark. When your lights first come on is when you use the most Co2 then once your room fills to the PPM you have set then it kicks on and off to keep it steady.

I needed to move my grow op. for security reasons and am now going for a sealed environment. I have 10Kw of A/c installed. My concerns were for co2 usage, which I don't have experience with. I'm going to buy a burner with a pilot light as I can't locate blu-ox over here (Europe). Its not a big deal since the gen. will be outside the growroom, the room being tubefed. This keeps growroom heat down and imo its much safer to have propane/burner at a distance. You mention that you use 2 x 20lb tanks per grow. That seems pretty reasonable. I've done my co2 calculations, but the variable is plant consumption. What you are indicating is that co2 use is not that huge once the room is up to the desired ppm ?
I noticed you had an air scrubber listed in your equipment. This is something else I will need to install in my grow. Smell suppression is very important in my new home. How big a scrubber/fan do you use in yr. room ? Does it entirely suppress smell ?
A word about AN : I tried them a couple of years ago...the full program recommended by their website. Hugely expensive, like $1000 in nutes for a grow ! I honestly didn't see an improvement on the GH nutes I normally use.
