'Wal-Mart of weed' opens in Oakland

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 that's believed to be the largest in the state.

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...

The opening of this Wal-Mart of weed arrived as California residents consider whether to support a statewide ballot measure to allow recreational marijuana. Proponents plan to turn in about twice as many signatures as needed to qualify the measure for the November ballot.
