Why the Hybrid R is the Right Structure for Cut Flowers

Low-growing cut flower varieties, gerbera (18 to 24 inches tall), ranunculus (12 to 18 inches), and anemone (12 to 18 inches), are ideal Hybrid R crops because their compact stature fits the multi-tunnel profile without clearance issues. Birdproof venting is critical: birds are attracted to the bright petals of gerbera and anemone and can destroy an entire picking in a single morning, and the Hybrid R's insect-screen vents provide complete physical exclusion without reducing airflow. The structure also protects the delicate petals from rain damage, a single storm during bloom can reduce marketable flower stems by 40 to 60% in open-field plantings.

FAQ

Cut Flowers in a Hybrid R, Common Questions

Can I grow gerbera daisies commercially in a Hybrid R tunnel?
Gerbera is one of the top 5 cut flower crops in North American production, and the Hybrid R is a cost-effective structure for gerbera because the crop's low profile (18 to 24 inches from ground to bloom) fits the multi-tunnel geometry well. Gerbera is a perennial in zones 8 to 11 and performs as a 2 to 3 year perennial under tunnel protection in zones 6 to 7, amortizing structure cost across multiple years. Top producing varieties for North American markets include Salvadori, Mega Revolution, and the Germini mini-gerbera series.
Is birdproofing really necessary for cut flower tunnel production?
Absolutely, birds cause a disproportionate share of cut flower crop loss compared to their impact on other crops because they target open blooms, which are the highest-value part of the plant. Mockingbirds, starlings, and house finches are the primary offenders in most US regions, and a flock of 20 to 30 birds can destroy 500 to 1,000 stems in a single morning in an unprotected field. The Hybrid R's continuous insect-screen perimeter vents eliminate this risk entirely without restricting ventilation.
When is the best time to plant ranunculus and anemone in a Hybrid R?
For peak spring holiday markets (Valentine's Day, Mother's Day), ranunculus corms are planted October, November and anemone corms September, October. Inside a Hybrid R, these planting windows can be extended 4 to 6 weeks later than open-field planting because the structure provides the 45 to 55°F corm development temperatures these crops need without the crop being exposed to damaging frost below 28°F. This flexibility allows growers in zones 6 to 7 to produce ranunculus that would be frost-killed in an unprotected field.
How many gerbera plants fit in a 9.6 m wide Hybrid R, and what is the expected yield?
Gerbera is typically planted at 30 cm × 40 cm spacing, yielding approximately 8 plants per m². In a 9.6 m × 50 m Hybrid R (430 m² net area), you can establish approximately 3,400 gerbera plants. At commercial yield rates of 150 to 200 stems per plant per year after establishment, a fully planted 9.6 m bay produces 510,000 to 680,000 stems annually, sufficient to supply a consistent wholesale account with 10,000 to 13,000 stems per week.
