The Big Tomato was helping home growers long before the dispensary boom, selling indoor gardening supplies for over two decades. Now owned by Schwazze, a Denver-based cannabis corporation, the Big Tomato still offers the same friendly service for newbies and regulars, but now has even more of a cannabis focus — and an online shopping option, to boot. For beginning green thumbs, finding a trustworthy growing store is like searching for a new mechanic; more cynical shops can take advantage of that lack of experience by suggesting unnecessary lighting equipment and nutrients. That's not the case at the Big Tomato, so don't be afraid to ask questions.
