Ventilation
Air exchange, side openings, roof form and insect net can strongly affect heat and humidity inside the structure.

Site-first planning
A protected structure is a crop-production system, not only a frame
Ag-En Plus treats equipment as part of a production system. The correct choice changes with site conditions, crop, water, operating capacity and the level of control actually required.
Covering choice
Film, shade net, insect net and other coverings should match crop protection, light, durability and maintenance needs.
Wind & anchoring
Exposure, terrain and site conditions influence anchoring, bracing and structural detailing.
Irrigation integration
Crop rows, filtration, fertigation, drainage and pipe routing should be designed with the structure, not after it.
Access & workflow
Doors, paths, crop handling, sanitation and material movement affect day-to-day operating efficiency.
Season strategy
The structure should reflect whether the goal is rain protection, season extension, heat management or more controlled production.

Adapt the engineering decision to the site
These are planning contexts rather than fixed prescriptions. Final sizing and specifications should be based on a site-specific assessment.
Hotter lowland sites
Ventilation, shade, insect protection and water availability can become dominant design considerations.
Valley production
Commercial vegetable, nursery and peri-urban systems can benefit from efficient space use and planned water storage.
Mid-hill sites
Wind exposure, slope, access, drainage and structural anchoring deserve site-specific attention.
Cooler high-elevation sites
Season extension can be valuable, while wind, cold, condensation and material access require careful planning.
Project workflow
Turn a broad farm idea into an engineering brief
A useful quotation starts with measurable site information. This reduces guesswork and makes product quantities, water-system decisions and installation scope easier to define.

Frequently asked questions
Make the technical scope clearer before buying
Exact specifications, commercial terms and installation requirements should be confirmed against the final project scope.
What is the difference between greenhouse and plastic tunnel?
Both protect crops, but structural strength, ventilation, covering, height, lifespan and level of control can differ substantially.
Is a greenhouse suitable in the Terai?
It can be, but heat management, ventilation, shade and crop choice should be considered carefully for the site and season.
Does protected farming still need irrigation design?
Yes. Protected crops often depend on precise and reliable water delivery because natural rainfall is partly or fully excluded.
Can a structure be expanded later?
Many modular designs can be planned for expansion, but bay geometry, water capacity, drainage and access should anticipate it.
