Yo man, I hope you still have it! I was in a similar dilemma a few years back. I did have some experience with one that I had tossed when I moved. Then a friend gave me another one - much the same condition as yours. Not wanting to waste the oportunity OR to stay in contact with the manufacturer, I decided to "experiment" on my own. What I found did that good ole' Miracle Grow potting soil and fertilizer worked as good as anything. Before long I was producung a harvest every 3-4 months. I did do some adjustments to the light cycle but what the hell, better than throwing it away! I settled on a cycle of 20 hours light during vegetative cycle and 12 hours during "flowering" cycle. And I only use the center fixture (with compact florescent bulb) to speed up maturing the buds. Hope this helps... someone anyway. Comments anyone?
