Are you insinuating that is a bad thing?
What if I double paned the glass??

no i am not insinuating anything ....... i'm flat out saying it is a bad thing.
what materials do you plan to use to SAFELY build a ghetto air cooled reflector? do you think your version of an ACR is going to be better than what you can buy cheaply? how many hours will you invest in testing your idea before you realize it is not really cutting edge ?
listen to 5th and take a look at the bisquit box
one question ....... is this whole idea based on the fact that you think you are going to get away with not needing a scrubber?

The whole idea is based on the fact that, while you can cool a HPS light with a PC fan, it becomes impossible when you add a carbon scrubber
And what are you talking about buying cheaply? Remember, I'm still a noob.
You haven't sourced out to see what any of this is going to cost you?
It's like green said, your trying to improve on something that doesn't need any improvement.
Find a grow here you like, copy best you can....it really is that straight forward.

Forgive me, but I do not see where anyone else has attempted what I'm describing. I see people who have put a glass shield between the light within the same box, but the bulb, the ballast, etc, is still in there heating things up.
Okay. It'll work great. It's a fuggin' flash of genius that no one has ever thought of before!
And all these people with years of actual growing experience using high intensity lighting in small enclosed spaces are just jealous, 'stillanoob'.
Seriously, hammer something together, evaluate, and revise.
Or just get an air-cooled hood and set it on top of a box.

Yes it will be diminished the same as it would in an air cooled hood. Depending on the type/size light you use I would probably avoid plexi as well due to yellowing/warping.
You seem to be stuck on the fact that because the light is outside of the box that this is a new idea. "Outside" of the box is a matter of perception. If you build 2 boxes and stack them on top of each other and connect them doesn't it then become one box? I understand you are sealing the light in it's own compartment, but this is what an air cooled hood does. Air cooled hood aside, this has literally been done hundreds of times on this site alone. You are just compartmentalizing the light.

Also with hid orientation/ light spread is a consideration.
Conventional experience says a store bought hood is the way to go,
maybe 75 bucks plus ballast +/-. I went with a diy cooltube, remote
Advance brand magnetic ballast.
For me the tube is easier to cool with my 80 mm axials. The box is vented
through a 4" x 12" store bought scrubber with a S&P 125 on a Variac speed
control.
My flower box is 18" x 18" x 24" high. I don't flower in the summer
months due to ambient temps above 90F. Otherwise temps 5-7F
above ambient. Yup.

noob you have to understand that most of us have built more than one system and it usually does not take too long to run into the limitations of what you build.
trying to "wing it" on your first build will probably get you to a place you don't want to be and trust me you don't want to be the proud owner of a system you can't make work because of a dozen or so things that you just didn't think about
go with something that has worked for other people
you could be the best grower here, but without being able to control the temps in your system you are still going to get your ass kicked and have bad results at the end of the day
good luck with whatever you do! and try to remember that the guys criticizing your ideas are trying to help ( that is one of the hardest things to get your mind around at this site)

Also consider that a hps will heat up the surrounding area, raising the ambient temperature of your room. If your room is not well ventilated it doesn't matter how cutting edge your box design is.
If I were you I'd just build your box wil cfl/pll and get some seeds going. The growing part is much more challenging than box design, at least for me it is.

Ok, so the more I think about it, I guess the more my idea seems like a whacky stoned moment.
So let me ask you guys a few things.
Comparing a 125w cfl and a 70 watt hps, which one is going to heat up the box more? I don't mean the surface of the bulb, I just mean that box its self.
Also, do you guys think if I go vertical and surround the cfl will I yield just as much as the 70w hps and also is 18x18" enough horizontal space or do i need more? One thing I worry about is that my indicas will branch out too much and I'll be forced to chop branches off on the non-light side, won't that stress the hell out of the plant and stunt it's growth?

To be honest I have never seen a 70W HPS in real life but I can tell you that a 125W CFL dosn't give off much heat. I would be surprised if a 70W HPS gives off less than a 125W CFL to be honest. The least amount of heat is given off by LED though.

One of my worries is getting airy buds. I know you can easily get 1oz from a 125w cfl, but every harvest pic of cfl's I've seen has shown these thin, stringy colas with huge stems in the middle, or people complaining of airy buds....and, I *hate* airy buds

You're getting way ahead of yourself, my eager friend. Unless you already have a box with branchy indicas that you can show us, there is no way to know what you'll yield. Genetics, pot size, veg time, plant health, distance to light, nutrients, heat, humidity, airflow, odor control... all these things play into yield and overall success with your grow.
That said, a 70w hps is probably ok in a cab that small. Build a cooltube for it. Maybe have a 125w cfl for backup if temps get out of hand.
if i were you, i would scrog in that size cab with that amount of light

IMHO it can be argued that as far as light usage you are always better off going vert, but there are people who would disagree
i can tell you that there is more to do as far as pruning and such with a vert system IME. that kinda translates into yet another learning curve. it's not a bad thing, and there is enough information around here to help you out, but i don't know if your first grow is when you want to be trying to learn everything
Marlo's grows are pretty fucking impressive if you want to see how to control plants in a small area. he is not running a grow box he can sure as hell make you shake your head in wonder every time you read the measurements of his room. check the WoW thread

thats exactly why i suggested a scrog for him.
me persoanally, i grow horizontal. however i do think vert is a great way to up your yields and maximize light usage. i have no problems with vert growing. i think its pretty cool and i will probably be giving it a try someday myself. its just in this instance, i feel stillanoob would have an easier go with a scrog to begin growing.

well it's not my first grow, just my first micro grow inside of a box. my living situation changed from a rural house to an urban apartment. the problem i have with scrogging is the added veg time........though i'm conisering all possibiliites still.....question how wide are 125w cfl's, i'm trying to figure out if 18" is wide enough to surround one with 4 plants
