Some of it is used to produce vegetables, although customers at Mighty Grow on Monday were overwhelmingly budding pot farmers. "We are here to help people grow plants," said Jim Luck, who works at the store on W. Michigan Avenue. "They grow everything from tomatoes to orchids, citrus and marijuana." Mighty Grow features dozens of brands of organic fertilizer for hydroponic operations and all of the equipment required for growing plants indoors without soil, including a large tent that can be outfitted with pumps, pots, lights, tanks and aeration for $1,600. The floor model contains a small jungle of gangly cherry tomato plants that have never tasted soil. Their roots live in a clay medium and are bathed at programmed intervals by aerated, nutrient-rich water. "Hydroponics means water at work," Luck said. It is a niche that has expanded greatly under Michigan's medical marijuana law. People with medical clearance can grow marijuana for themselves and others with prescriptions. The growers call themselves caregivers. "I decided to grow on my own because I thought it was cheaper," Jackson grower Mary Robbins said, rolling her eyes. Robbins has arthritis, bulging discs and pain from several car crashes. Pot prices rose from $65 a half-ounce before the medical marijuana law to more than $100 a half ounce, because growers are trying to retrieve their investments and capitalize on potent weed, Robbins said. "Modern strains of pot will knock you on your ass," she said. Growing marijuana indoors is incredibly complex, Robbins has learned. She has one prospective "patient" if she is able to grow a reliable supply. It has been a hard-knock education with plenty of setbacks. Strains of pot are as varied as grapes, and each has its own traits and requirements, she said. Among the strains are White Widow, Train Wreck and Blue Berry. Growers buy seeds from a network of suppliers. Luck said he does not sell pot seeds. Mighty Grow does not offer classes, but there is a running dialogue among customers and Luck regarding growing tips and troubleshooting. Luck said marijuana growers are just one segment of Mighty Grow's customer base. Many Jackson-area residents are learning how to stretch their gardening season by keeping indoor hydroponic gardens. "I have people who grow citrus trees in their basements, wheat grass, lettuce, orchids and tomatoes," Luck said. Mighty Grow is open from 10 a.m. to 6 p.m. weekdays and from 10 a.m. to 5 p.m. Saturday. - --- MAP posted-by: Matt
