I don't know how serious you are about your lighting but it's pretty F@#$ing important..... if you would like I will direct you to a system with a top of the line switchable ballast (400 watt MH/HPS) and Sun Gro hood, a MH bulb (for veggie growth), glass, all cords AND postage all for under $400.00. That is what most people spend for this system without the switchable ballast......if you swallowed the hook then just reply and I'll put up the link........
