In a 15,000-square-foot warehouse just down the road from the Oakland Airport, an entrepreneur is opening a one-stop shop for medicinal marijuana cultivation. Don't know the first thing about growing pot? The folks at iGrow have a doctor on site to get you a cannabis card and sell you all the necessary equipment for indoor, hydroponic cultivation - from pumps, nutrients and tubing to lights and fans. Don't know how to set it up? For a fee, on-site technicians will show you how to build it in your home and even maintain it weekly. This is hardly a fringe business. When iGrow opens today, at least three City Council members will attend. So will most of the leaders of the cannabis industry in Oakland, a city long at the vanguard of medicinal marijuana. Though iGrow provides all the supplies and know-how for cannabis cultivation, they don't sell the seedlings - only dispensaries can. The cost of creating your own cultivation system or relying solely on a dispensary is vast. At a dispensary, a patient might spend $120 a week for a quarter-ounce of marijuana. However, it might cost $1,000 to set up an eight-plant system. But in the course of a year, they might only use half of their harvest and be able to sell the remaining 3 pounds for $12,000 to a dispensary
