Politics and profit mixed with health promises and some hip technology at the second annual Medical Marijuana Expo in Detroit over the weekend, says the Detroit Free Press. Some 135 vendors from Michigan’s fledgling medical-marijuana industry showed wares and touted services to a crowd that, at times, was jammed shoulder to shoulder. “This has gone from an industry in the closet to some very technologically advanced stuff,” said Jason Ray, 40, an Ohio horticulture consultant. He was doing market research for a company that plans to sell high-tech grow lights to marijuana growers.
“People are actually making money. There’s a guy here selling 180 air-conditioning units a day” to people whose grow lights generate excessive heat, Ray said. A group was collecting signatures to put a proposal on the Michigan ballot that would allow limited possession of marijuana. Security cameras disguised as rocks were going for $74 apiece. A just-add-water mix of potting soil and fertilizer was $40 for 2 liters and called Michigan Made Mix. A 15-by-25-foot structure covered with clear plastic film for growing the plants — called a cold frame — was $900, with greenhouses going for up to $10,000.
