Don't buy mylar....
Mylar works, but there are other types refelective material you can get that is more efficient.
I use panda film. It's white on one side and black on the other. The white acts as your reflector, and the black helps fight mold & mildew.
Plus, when cleaning your grow area, you should spray down your walls every so often. When using the panda film it doesn't smear when you wipe it down. Mylar leaves smear marks.
Plus, mylar creates hot spots in your grow area.
You can buy Panda film at just about any Hydro shop.

PC fans are light.
Yeah ive read about people usin pc fans but idk how to wire them to a power source and i really dont want to mess something like that up and start a fire. Also, this may be a stupid ? so i appologize ahead of time, but is it possible to have too much light im starting out with only one plant and i plan on having as much as 10000 lumens on this baby, one 80 or 105w on top and as many as 4 20w surrounding her when she gets older, is this too much or is there no such thing?

Take a look at this. It would still probably need some minor mods, but should work just fine. CS 110v AC to 12v DC Power Supply with 4 Pin Molex Adapter

Spray mount is great to adhere the film to the walls.
Hey everyone, thanks for all the help so far just a few more ?s I was at home depot the other day and saw some big 100 cfls in the flood light section. I looked on the box but could not find any indication as to what the spectrum may be, does anyone have an idea as to what they may be? Also, would i be able find this roof paint at home depot?

Quoted for truth. Mylar, in my experience, is a pain in the butt. Flat white paint is nearly as effective and with the diffusion of light that you'll get with flat white paint you'll avoid hot spots on your plants which can cause burning of the plant tissue.
If you do use mylar around an ionizer, be sure that you ground out the mylar. With the high voltage ions given off by the ionizer, the mylar can build up an electrical charge (it will act as a capacitor) which can give a painful yet harmless electrical shock.

If 70% vs 90+% is nearly, then ok.
Great tip about the grounding!! Bust some of us are masochists.

hmmm....I don't know where you get 70% for white paint....it's more like 85-90%.If 70% vs 90+% is nearly, then ok.

I *gotta* send in some samples to a place I worked to have tested.
Now, the reflective ratings, at what angle? The percentages can be *drastically* different from head on vs say 30 degrees. Now head on ratings are *useless* for a wall unless you have your lamp on the opposite wall.
I have used a spectrophotometer on a daily basis. Measuring transmission, reflectance at various angles, and done the curves for them along with the curves for photopics.
Now far from an attack. I've read so many things here, just sorting them out. You have *good* points.
3/4 of the curve of that last PDF is in the near and mid IR range! Its meant to reflect *heat* aka IR It goes out past 2200nm
