Greenhouse for Spinach Growing
Greenhouse spinach enables continuous production through hot months when field-grown spinach would bolt within days. Temperature control is critical for this species: above 75°F plants activate irreversible bolting that makes them unmarketable. A greenhouse with proper ventilation and diffuse plastic allows spinach production in any season with consistent quality.

Bolting prevention
Keeping temperatures below 75°F is the only way to grow quality spinach through summer months or in warm climate zones.
Clean leaves without soil splash
Overhead cover eliminates soil splash that stains spinach leaves, reducing washing labor and extending fresh product shelf life.
Fast 30-40 day cycles
Stable temperature and controlled irrigation accelerate the cycle, enabling 8-10 annual harvests with precise volume and delivery scheduling.
Agronomist Tip
Use plastic with at least 60% light diffusion in spinach greenhouses, intense direct light raises leaf surface temperature several degrees above air temperature, accelerating bolting even when ambient temperature is controlled.
