Commercial Thailand Light-Deprivation Greenhouse with Hydroponic Growing Systems
A turnkey, fully-controllable greenhouse engineered for large-scale, high-value crops (flowers, herbs, leafy greens, berries and medicinal plants) in Thailand’s tropical monsoon climate. By combining 100 % automated blackout with soil-less hydroponics, growers can schedule 3–5 harvests per year regardless of external weather or photoperiod.
1. System Composition
• Primary Structure
Heavy-gauge hot-dip galvanized steel arches or Venlo-style glass/PC roof, rated for 40 m s⁻¹ winds and 25 kg m⁻² snow load.
• Automatic Light-Deprivation Package
Double- or triple-layer blackout curtains + reflective breathable layer achieve 99.9 % darkness in <30 s; precise photoperiod control triggers flowering or delays harvest on demand.
• Hydroponic Rigs
NFT, DFT, or substrate-bag systems with inline EC/pH sensors, automatic nutrient dosing, UV sterilization and closed-loop return that cuts water use by 70 %.
• Environmental Control Suite
Negative-pressure exhaust & wet-pad cooling, internal thermal screens, CO₂ enrichment, LED supplemental lighting, high-pressure fogging—all PLC or smartphone-app controlled.
• Optional Add-ons
Rolling ebb-and-flow benches, automatic seeder, monorail harvest carts, integrated RO + ozone sterilization for drain water.
2. Key Advantages
• Multiple Cycles per Year
Blackout + supplemental lighting compress crop cycles, raising annual yield per m² by 2–3×.
• Absolute Darkness
Prevents light pollution from nearby roads or full moon, critical for photo-sensitive cultivars.
• Water & Fertilizer Savings
Closed hydroponic loop uses only 20–30 % of the water required by open-field cultivation.
• Fast Deployment
Bolt-together kit, no welding; Thai technical crew can erect 1,000 m² in 7–10 days.
• Certified Durability
ISO 9001 steelwork, UV-stabilized covering (10-year warranty), blackout curtain tested for 50,000 cycles.
