light fixture question

i have a cooper lighting fixture its 12"X15"metal box and has 2 bolts on the side but i dont have the mount. What is the best way to mount this damn thing it wont stay balanced well i havent tried it yet still tryin to get all my shit right without spending the dough. it was free so im using it i have CO2 tank and regular regulator and computer fans so i should be good this is the first time i used a hid its a 400 watt MH it still has the reflector. should i rig it up out of the box or keep it in the box/ it is siutable for wet locations. Any info would be helpful this is the first time ive ever did this shit the right way...kinda my space 41" X 21" X about 5 1/2' tall how many should i do with that small of space and only one light???????? sorry for all the questions but i want to know everything before i do this again thanx for any input

You need a better light. A Metal Halide light wont do much when it comes to flowering your bud. You need an HPS bulb. They are going to veg nice though. I'd say about 3 or 4 plants with only a 400...maybe even 2 really big ones. In this business you're gonna have to spend some dough. At least on lights. I have yet to see a DIY guide on how to build light bulbs so try not to skimp on food and water and lights. You don't need co2 and tons of chemicals but you do need good light and clean pure water. I have no idea on how to mount a copper lighting fixture seems I have never used one. Use the reflector. It'd work better at reflecting then copper. Seems copper is a dark colored metal it shouldn't reflect very efficiently.

its not a copper light fixture its a cooper edison. like a parking lot light and MH can be used the whole grow from what ive heard

Well a MH CAN be used but you are going to get results far less then you could if you used a HPS bulb. I have seen the parking lot lights used but they usually have to be wired etc and are just sketchy all around.

Sell the light to someone and buy a real fixture so you don't start an electrical fire. Fire is bad.

Dude Kodank, I need that avatar... How do you get them to do movement instead of just a flat picture. I wouldn't use it on this forum since you have it but i'll use it on one of my others. When I save it as a pic its obviously only a pic, so any idea how to make it like yours... Sorry for going off topic (I hate when ppl do that on my posts lol my bad,) lmk thnx

Could you get some pics up of this copper edison?
