I apologize if it wasn't completely clear, but I already have a flowering HPS. Item one in my post describes two possible setups for the veg stage.

In other news, Seeds Boutique came through like a champ today with two-week delivery, an extra seed of my chosen variety, and a free pack of fifteen Skunk #1 seeds. None of the seeds were crushed or broken, though two of the free Skunk seeds looked a little immature. Pity the Skunks, for they'll soon run the gauntlet of my inexperience.
