stealth CFL DWC cabinet 20x20x24

Before I begin, feel free to post with any advice or CONSTRUCTIVE criticism that you may have, bear in mind that at this point it is still a work in progress and I have read more than a few things on this site and others and that I have grown outdoors a few times.

With that being said, here I go.

I just want to grow 2-4 plants at a time with the intention of growing 30-45 grams per month for personal use. It want to make it as stealthy as possible, hopefully with no sound or smell at all when it is closed up.
I intend to do this for cheap and use what I have or what I can easily obtain for materials without having to spend way too much at the hydro store.

The Cabinet that I have chosen to use is 20x20x24 with a door on the front, it is a cabinet on the top of a very large wardrobe. If this is successful, I will convert the whole unit to a SOG (Sea Of Green) cabinet with a full propogation and vegetative area.
I removed a shelf that was in the cabinet, wiped it down and sprayed it with lysol, then I put a fan on to dry it overnight.
Next I put a layer of bubble wrap on the walls, ceiling and door with the hope that this might help to contain some of the sound.
I then put tinfoil over the bubblewrap with the shiny side facing out and into the area.
I then drilled a small hole in the top corner to run wires through, ran my wire, added timer, a power outlet thing (*thats the technical term), 2 powerbars and some lights.

The gear I will be using:
-Small DWC box for 2 plants (there is room for 1 more box of the same size).
-60G airpump (has 2 outlets so it could run both dwc boxes in the future).
-adjustable airstone X 2 (foam type)
-For airflow and to reduce the smell I will use a 4" 90CFM inline fan, 4" reflective ducting, reflective tape, charcoal perfilters, dryer sheets, and when I can find some activated charcoal... I also got a thermostat which I will not be using yet.
-powersplitter, 2 powerbars, 4 plug in lightsockets (more to come)
-4 2700k cfl bulbs for flowering and I mistakenly got 4 3500 K bulbs that I will be exchanging for 5500's for vegging
-I also got a 18" tubelight

I will be using lava rock as the medium with sponges as the collar.
I purchased the cheapest nutes I could find on EBAY.

I also included a pic of the wardrobe as I forgot in my last post.

So, I have my space with tinfoil and electricity but not much else.
I have made a rack to hang my lights upon so they can be more centered over the plants and easier to raise and lower.
I have also made some reflectors for my CFL bulbs from pop cans, I am hoping these will be effective.
I will be fitting it all into the cabinet and giving it a dry run for a while to ensure that it is all good to go then I will sterilize the res and the lava rock and I will be good to go.
I have some substantial light leaking out around the door that I will fix with some weatherstripping.
I will be blacking out my res with reflective tape as well.
I am in no hurry to install the air/smell system until I can find some activated charcoal (Walmart didn't have any), my seeds are still in paper towel so I have some time.
