Greenhouse Farming in Kenya: 2026 Cost, Crop Selection & Profit Analysis

Key Farmer Takeaways & Action Points

  • An 8m×30m commercial greenhouse accommodates up to 1,600 indeterminate tomato vines, producing 20–25 tonnes over an 8-month harvest.
  • Metallic galvanized structures have a 25-year structural lifespan with lower maintenance overhead than wooden units.
  • Off-season timing between July and September commands up to Ksh 120 per kg at gate prices in Nairobi and Mombasa.

1. The Economics of Protected Cultivation

Open-field tomato production in Kenya is increasingly vulnerable to unpredictable erratic rainfall, sudden hail storms, and devastating blights.

Under an enclosed commercial greenhouse, water evaporation drops by 60%, pesticide use drops by 85%, and indeterminate varieties produce up to 5 times the yield of open field crops.
