Killerweed,

Great job on recovering the them Big Buds,

Looks like your sold on florecents, for a closet grow that is probably the way to go.

If you have or can get good ventelation in there, HID lighting is the way to go, Like ESP13 said you would have increased your yeild significantly.

You can get a 600w digital ballast that will take both MH and HPS bulbs, both bulbs included ,with retractable hangers, and reflector for $316.00 shipping included. At htgsupply.com

They might even have a better price on the light system you are looking to buy.
Great prices and pretty much one stop shopping for any and all your needs.
