Why the Hybrid R is the Right Structure for Blueberry

Blueberry bushes reach 4 to 6 feet in height at maturity, so the Hybrid R's clearance and wide span, rather than a low-profile tunnel, is required to avoid canopy compression and airflow restriction. Because blueberries are a 10 to 15 year perennial investment, the Hybrid R's galvanized heavy-gauge structure and 90 km/h wind rating provide the durability needed to amortize the structure over the full crop life. Rain protection under the poly film directly eliminates the late-season botrytis and fruit cracking that can destroy 20 to 30% of open-field blueberry yield.

FAQ

Blueberry in a Hybrid R, Common Questions

Can I grow blueberries in a multi-tunnel greenhouse?
Yes, and commercial blueberry producers in Oregon, Washington, and Michigan are adopting multi-tunnel structures at an accelerating rate. The key requirement is adequate height clearance, mature Rabbiteye and Southern Highbush varieties reach 5 to 6 feet, so the Hybrid R's apex height (4.2 to 5.5 m depending on configuration) comfortably accommodates full canopy development with room for harvest equipment and pickers.
What is the ROI on a Hybrid R greenhouse for blueberries?
Blueberry growers using multi-tunnel protection report 3 primary financial benefits: (1) a 4 to 6 week season extension that captures premium early-season pricing at $4 to 7/lb vs. peak-season $2 to 3/lb; (2) a 15 to 25% yield increase from reduced botrytis and bird loss; and (3) lower labor costs from reduced spray applications. Most 1-acre Hybrid R installations targeting blueberries show full payback within 4 to 6 years.
What blueberry varieties are best suited to greenhouse production?
Southern Highbush varieties, Emerald, Jewel, Star, and Springhigh, are the top greenhouse performers because they require less chilling hours and respond well to controlled-environment season manipulation. In colder states, Northern Highbush varieties like Duke and Bluecrop benefit most from frost protection during early bloom, which can occur as early as March under poly film coverage.
Does growing blueberries in a Hybrid R eliminate the need for netting?
In most configurations, yes. The Hybrid R's birdproof venting system uses insect-screen mesh on rollup and ridge vents that physically excludes birds from the growing space, eliminating the need for overhead netting that is expensive, difficult to manage, and can damage fruit during harvest. This is a major operational advantage over open-field bird-exclusion systems.
