dude, my hydro store in Charlotte sells stuff for drying and they know exactly what your there for. Most of the people working there didnt get there experience from growing lettuce, atleast not the kind they sell at the grocery store. Just check out some of the hippied out labels on the nutes they sell, tell me there marketing to strawberry growers??
The hydro store can be a cool place to chill, but watch going there too often in the same vehicle, some desperate asshole cops will keep tabs from across the street or whtever... and I always try to take a different route home, make a a couple stops on the way.
