Greenhouse for Lettuce Growing
Greenhouse lettuce enables continuous, high-quality production year-round regardless of rain, frost or extreme heat. Temperature control is key to preventing premature bolting that destroys commercial quality. In intensive systems like NFT channels or floating rafts, a greenhouse multiplies efficiency per square foot up to 10 times compared to open-field production.

Bolting prevention
Temperatures above 72°F trigger bolting in lettuce, greenhouse ventilation management keeps conditions below that threshold during summer months.
Hydroponic system protection
The greenhouse protects NFT channels and nutrient solutions from external contamination, acid rain and sudden temperature swings.
30-45 day cycles year-round
Lettuce's ultra-short cycle allows 8-10 annual harvests under greenhouse with precise volume and delivery scheduling.
Agronomist Tip
Keep nighttime temperature between 54-59°F for greenhouse lettuce, this promotes head compaction and deep color. Warm nights produce loose, pale heads with poor shelf life and market value.
