A pair of hydroponic stores
Around the perimeter of the store are pallets of rock wool and Hydroton, shelves of books, and bottles and jugs of fertilizers. One of Humphrey's favorite lines is Advanced Nutrients out of British Columbia, but he also carries the more well-known General Hydroponics.
In the back of the store is a tangle of metal and glass, mostly lights: "We have a really expansive collection of recycled and used equipment. You need 200- to 1,000-watt lighting if you want to get any kind of high yield. Basically, plants eat light, you know."
Gro Blue is keeping-in fact, expanding-Geechi Bleu's T-shirt inventory. Humphrey says in addition to the hip-hop-flavored shirts, he'll be carrying more environmentally friendly and organic-themed clothing. And he's keeping sister Gigi's display case featuring her jewelry line, called "Chocolate Chipmunk," as well as body care products made from hemp.
