Lowryders in a mini greenhouse

Hey guys... I recently built a greenhouse that is 6 feet tall, 4 feet wide, and is 32 inches deep (with two shelves) leaving 3 feet of growing space for the plants. So thats 32 cubic feet of growing space for each shelf. I built this greenhouse with lowryders in mind...... & I plan to cover it with reflective foam board. So my questions are, How many lowryder #1's can I grow comfortably in this thing? What kinds of lights should I use? Should I grow them hydroponically with coconut coir in 2 gal buckets or in potting soil in 2 gal buckets? Or something different entirely? This is my first ever grow guys and all I'm really doing it for is some cash to get a serious grow going. Any advice is appreciated. Later guys!

What kind of electricity do you have? Calculate the exact amount of electricity you can pull, and then we can talk.
