"The GR-100 has been a game-changer for our labor strategy. We're no longer scrambling for pickers during peak season. The consistency is unmatched."

David R., Greenhouse Operations Director · June 2026

"The integrated quality check is the real winner. We've seen a measurable decrease in post-harvest sorting time and an increase in the quality of our packed tomatoes."

Maria S., Head Grower · May 2026

"It's an impressive machine, but be prepared for a significant upfront investment and calibration period. It's also limited to our tomato and pepper houses; we can't use it for our other crops."

Tom K., Farm Owner · April 2026

"This is the future of greenhouse farming. The ability to harvest around the clock without a drop in quality is a massive competitive advantage."

Chen L., AgTech Consultant · March 2026

Comparison

How it compares

While farm management software platforms focus on data and workflow, the GR-100 is a hardware solution that physically automates harvesting. Choose the GR-100 when your primary bottleneck is labor cost and availability for picking tomatoes, peppers, or cucumbers. Opt for farm management software if your goal is broader operational visibility and data tracking, rather than physical task automation. The GR-100 replaces a specific manual job, whereas software augments human decision-making.

The decision

🎯

Built for

Best for large-scale greenhouse operations seeking to automate harvesting and reduce dependency on manual labor for specific crops.

In-Depth Overview

For modern greenhouse operators, labor shortages and rising costs are a constant threat to profitability. The Four Growers GR-100 directly addresses this by automating the labor-intensive process of harvesting. Its system doesn't just pick; it uses 8 stereo cameras and advanced AI to perform quality checks as it harvests, ensuring only market-ready produce is selected. This dual function of harvesting and quality assurance reduces reliance on a fluctuating labor market and minimizes human error. The GR-100 is specifically engineered for high-value greenhouse crops like tomatoes, peppers, and cucumbers. By providing robotic harvesting and plant-level analytics, it allows growers to transition from managing large crews to managing a high-efficiency automated system, ultimately lowering production costs and stabilizing operations. The company holds two filed patents, indicating a commitment to proprietary, defensible technology that gives growers a competitive edge.
