Little Leaf Farms Becomes World’s Largest Indoor Lettuce Producer

Little Leaf Farms, a greenhouse producer of leafy greens, opened a new facility at its McAdoo, PA, campus. The new greenhouse marks the company’s fourth facility on-site and cements the operation’s McAdoo campus as the largest controlled environment agriculture (CEA) leafy greens facility in the world. The company now represents more than 54% market share among indoor lettuce growers.

Now totaling 40 acres, the Pennsylvania campus supports the company’s expansion into the Southeast, Midwest, and Canada, furthering the company’s mission to bring quality leafy greens to more consumers. Now available in more than 8,000 grocery stores, Little Leaf Farms is both the country’s leading CEA produce brand and the fastest-growing packaged salad brand.

“2025 marks a decade of transformation and growth,” says Paul Sellew, founder and CEO of Little Leaf Farms. “When we started 10 years ago, controlled environment agriculture for leafy greens was virtually nonexistent in the U.S. Today, Little Leaf Farms has expanded what is possible in CEA, reshaping retailer assortments and consumer perceptions and pushing the packaged salad industry into a new era of variety and quality.”

The greenhouse expansion will support consumer demand for Little Leaf Farms’ newest product, Romaine Leaf lettuce, which has doubled in national distribution since its launch in July 2025. With the launch of Romaine Leaf, Little Leaf became the only greenhouse in the world growing “teen” leaf romaine, which maintains the size of field-grown Romaine yet still preserves the variety’s classic crispness.

Little Leaf Farms recently announced a new campus in Manchester, TN. Once fully operational, anticipated in Fall 2026, the Tennessee campus will supply fresh leafy greens to the Midwest, Southeast, and Texas.
