Yup ProGro is right. You have no place to stick that bulb, aka, no hood which is more money. You would most likely be better off just buying something from a local grow shop. If anything you can actually haggle with the owner for a lower price and *most* grow lights come pre-assembled or at least close to it. Also you have the factor that the hood was designed for good airflow so your bulb will run cooler and last longer.
