RUINENG Greenhouse Engineering—headquartered in China and trading at filmgreenhouses.com—builds its reputation on low-cost, large-area film houses. The company’s standard offer is a galvanized-steel tunnel or multi-span block clad in single- or double-layer PO/PE film, designed for vegetable and flower growers who need to cover a hectare or more without breaking the budget. The frames are simple round-arch or shallow Gothic ribs, pre-punched and bolted, so no welding is required on site. Ventilation is provided by side-wall roll-ups or roof vents, and every project can be shipped with drip lines, pad-fan cooling, soil-less troughs and even a biomass boiler as one turn-key package. RUINENG’s sweet spot is temperate to sub-tropical zones where the main challenge is removing heat and humidity, not supporting snow.

Through a strategic alliance with Poly-Tex—New Zealand’s respected designer and manufacturer of high-performance structures—LONGXING merges world-leading greenhouse technology with proven local expertise. Together we deliver glasshouse projects that are tougher, smarter and more profitable for Kiwi growers.

Selecting a covering material for a vegetable greenhouse is a strategic decision that directly determines how much light reaches the crop, how much heat is retained or lost, how long the cover will last, and ultimately how profitable the winter or off-season harvest will be. The main options used today are compared below on the five criteria that growers most often cite.

A well-designed ventilation system is the “hidden motor” of a modern vegetable greenhouse, because it simultaneously solves four critical problems that would otherwise limit yield and quality.

When it comes to choosing the right greenhouse plastic film, it’s essential to consider various factors to optimize growth conditions and ensure longevity. Here are some key points to guide your decision:

These innovative structures have revolutionized the way we grow produce, extending the growing season and improving crop yields while minimizing environmental impact. High tunnels provide a controlled environment that protects plants from harsh weather conditions, pests, and diseases.

1. Superior Light Transmission • Ultra-clear tempered glass (≥91 % light transmission) guarantees uniform PAR distribution across every plant tier, boosting photosynthetic efficiency by up to 18 % compared with standard coverings.

LAGUNA, Philippines—Across Asia-Pacific, operators of commercial greenhouses are ripping out low-margin lettuce and replacing them with crops that fetch restaurant-grade prices. The goal: turn every cubic metre of climate-controlled space into a high-frequency cash register.

In modern agriculture, the use of various plastic films has revolutionized the way crops are grown, improving yield and quality while extending growing seasons. Among these, greenhouse films play a pivotal role in creating a controlled environment that enhances plant growth. While ground films are also a form of plastic film used in agriculture, greenhouse films differ significantly in terms of their functions, properties, and benefits. In this article, we will explore the various aspects of greenhouse films and why they are essential in modern agricultural production.

Tropical fruit can be grown successfully in a greenhouse. By precisely controlling temperature (24–32 °C), humidity (60–80 %) and light intensity, a greenhouse replicates the native equatorial climate and enables bananas, papayas, passion-fruit, guava, dragon-fruit and dwarf mango varieties to set and ripen far from the tropics .

• Greenhouse acreage has expanded by ~1,000 ha in the last five years; vegetable output doubled to 1.1 Mt in 2021 and is projected to reach 1.6 Mt by 2025. • Cucumber: 830 kt (95 % self-sufficiency, surplus for export).

Demand is huge—Russians consume large quantities for fresh salads and, especially, for pickling. Modern winter greenhouse projects in Yakutsk already deliver ~1,692 t of cucumbers per year, and wholesale prices remain high from November to April.
