Indoor stealth cfl grow

Alright guys im fairly new to the site but i have a grow or two under my belt. This grow will be from bagseed of northern lights. I have the seeds germing right now and i will put them in the box. My box is inside of an ottoman that has the inner storage compartment. Ive wrapped the inside in mylar and have a cfl floodlight mounted at the top. I also have a fan that i am installing in the box for airflow. Im thinking about starting the plants in soil then switching to hydroponics once they reach a few inches tall. Any ideas on how to make this small of a hydroponic system, my box is 17 inches tall and 15 inches in diameter. Ill put up pictures later tonight.

Still waiting on the seeds to germinate but after that theyll be into the box

UPDATE: germed four seeds, gonna start them all in the box then move two outdoors. I will post more pics when they reach one or two inches tall.
