Thanks so much for getting back to me so quickly! I appreciate your input.
I'll definitely take a look at some of those MH posts as it's more than likely a safe call. And I hear what you're saying about the glass housing, as my next thought was to cut a hole in my hood and plum the ducting right up to the light.
Thanks again for your input. Without saying too much, the long and the short of it was when I was much younger I was my fathers trimmer and unfortunately I didn't get to learn enough before he stopped all together. The lights were his and I'm giving it a go on my own. I'm sure it'll be an interesting experience. Thanks again.
Do you mean you're on a VPN or that there just so many huge grows out there that you're not concerned? I was curious how many people posting here reside where it's frowned upon vs okay.Understood. But for me it's the opposite... I feel safe here because I'm a small, anonymous fish in a huge pond.
First of all, yes, you can do a grow entirely under MH lighting. There are entire threads dedicated to this very subject on just about every grow forum. The general consensus, which corroborates my own experience, is that it leads to smaller yields than HPS, but more trichome production. That being said, 175w is a bit underpowered for that sized space, but 400w is borderline too much, so the decision hinges on the ability to deal with the heat. Based on the fact that you don't have an air-cooled hood, I would choose the 175 if I were you. The only way I was able to do a 400 in my 2x2 tent is because I used a cool tube. And even then it was tough keeping things cool in there. So without an air-cooled hood, there's no question about it... I recommend the 175.
Yeah, like I said above, heat would absolutely be an issue, even trying to do the duct thing you described. It has more to do with the radiant heat coming from the bulb than it does the build-up of heat from the wattage. Those HID bulbs up above the 250w level really throw some heat from the bulbs, regardless of how much air is moving through the tent, and that glass really helps to keep the radiant heat away from the plants.

I'm sure I talked about my watering setup in previous threads but I can't remember off the top of my head. I would say just look through all my journals until you see what you're looking for. You can do a thread title search with the word "hush" and find all of my journals. I always make it a point to put my name in the thread titles for this very reason. It's how I find my own threads when I'm searching for them.
Basically though, I can briefly sum it up by saying all I do is use a pump and some irrigation tubing, connected to a digital timer. If you have more specific questions about this that I'm not answering then fire away.
