A detailed depiction of three grow tents of varying sizes for different numbers of plants. Start with a smaller tent huddled in the corner with two small potted cannabis plants under a single grow lamp. Next is a larger tent with six potted plants sprouting bigger leaves under multiple lamps. And the largest tent with 20 pots covering a wide expanse under a network of high-intensity lamps. Emphasize the size aspect by placing a common object next to the tents, like a watering can or a gallon jug, for reference.
