Macrotunnel for Spinach Growing
A spinach macrotunnel is effective in temperate climates where the main goal is protecting the crop from heavy rainfall and hail that physically damage leaves. Natural ventilation through open ends helps keep temperature in check, reducing bolting risk on hot days. For cut spinach or baby leaf production, a macrotunnel provides adequate protection at a very competitive cost.

No physical leaf damage
Heavy rain and hail shred spinach leaves which are thin and fragile, a macrotunnel eliminates this risk that can ruin an entire harvest in minutes.
Natural ventilation delays bolting
Open ends allow airflow that cools the crop on hot days, delaying bolting without active ventilation systems or additional investment.
Production during rainy season
Enables cycle planning during rainy months that are normally outside the productive calendar for open-field spinach in tropical and subtropical regions.
Agronomist Tip
For baby leaf spinach in macrotunnels, program drip irrigation in short frequent intervals rather than long spaced waterings, consistent uniform moisture produces more tender, uniform leaves with higher market value.
