Cabinet grow op

I'm starting to grow my first plant in an old cabinet I have, but am wonder about a few things. It's going to be Pineapple chunk for those that are interested. Anyway, the space is 34 in wide x 20 in deep x 33 in high. I can take out another shelf and make it bigger but that will require much work. Pineapple chunk is supposed to grow 60 to 80 cm (24 - 31.5 inches) high so I think that I will be off ok there, but with just 34 in wide how many plants should I grow? Also, I'm looking into HID lights, and I think I'm getting a 70 watt HPS bulb with 6700 lumens. Will this be ok? Also, I'm wondering how I install it since I'll need to wire it through a wall outlet. And most lights that are that high powered are lined directly into the system.

If i were you i'd only grow one or two plants at most, you may just have to take that shelf down. I have a grow space similar to yours and i didnt see the point on wasting money on a hps instead i spend about £25 on 6 cfl's which is perfect for one plant. If you ever get new seeds and use the same area you should grow autoflowers, you'd probablys be able to fit 4 lowryders in there.
