Case Study

Western Growers Case Study

How Carbon Robotics LaserWeeders are working for a 20,000 acre grower of leafy greens in Salinas Valley, California.

“The LaserWeeder's ability to eliminate weeds effectively has also allowed Triangle Farms to increase some of their yields, particularly with organic spinach and multi-leaf lettuces — usually around 10–15%, but sometimes as high as 50%.” Western Growers Center for Innovation & Technology — based on results from Braga Fresh and Triangle Farms

Leafy Greens Grower Stories

Primaflor

Primaflor, one of Europe's largest lettuce growers, shares how Carbon Robotics' LaserWeeder G2 transformed their operation. Since deploying their first machine, they've achieved a 75% reduction in hand weeding, reduced chemical applications, improved quality at lower costs, and stronger sustainability outcomes. The results were strong enough that they purchased a second machine.

Hussey & Co.

See how Hussey is using Carbon Robotics' LaserWeeder G2 to reduce manual weeding by approximately $20,000 per week, cut chemical use, and transition from transplants to direct seeding—something they say wouldn't be possible without LaserWeeder. Backed by hands-on support from the Carbon Robotics team, they're building a more sustainable and scalable farming operation.

Riviera Farms

At Riviera Farms in Australia, a 5th-generation operation managing nearly 2,000 hectares, LaserWeeder helped reverse the impact of rising labor and chemical costs. They've achieved a 70% reduction in chemical use, improved yields, and significantly reduced hand weeding labor. The technology is also enabling a shift from transplanting to direct seeding, eliminating nursery costs and simplifying production. Hear it directly from Mick Cox, Production Manager at Riviera Farms.

What Leafy Greens Growers Are Saying

The LaserWeeder automates one of the most demanding, costly, and time-intensive tasks on the farm: weeding.

LaserThinning is a breakthrough approach and delivers benefits that are an order of magnitude better than existing solutions.

We've seen an increase in quality and consistency of the crop.

Soon after adopting the LaserWeeder, we reduced our chemical use by 70%, which has led to healthier crops and improved yields.

After one season, our weeding labor was reduced by over 50%, and daily operations are now easier to manage.
