First Indoor Grow! Advice please

I have pictures of my setup on my profile under the picture section.

Here's what I did,

I took a 4 foot , 2 foot long cardboard box, I lined it with aluminum sheets and white plastic. I added a florescent light on the side and a florescent light hanging down. I also added a small clear Bright light on the other side. I'm not planning on growing ounces and ounces, I'm only growing what I can grow in such a small space. I have a few outdoor plants going but I wanted to see if I could SOG grow one plant indoors. As a grow medium I'm using something I made myself since I only want organic bud. I'm not finished with the box yet, I have to figure out how I'm going to exhaust it. I'm using bulbs that I bought for my fish tank to grow live plants. I'm hoping I can use these from start to finish but if not I'll go get a 200W HID light either hps or mh. I use only aquarium water since the fish produce nitrogen in natural form. Any advice would be greatly accepted. I know I don't have enough space to grow a super huge plant, Google bonsai weed plant, I'm kinda going in that direction just not as small.
