Journal — Greenhouse Know-how & Industry Perspective
Combining authoritative international research with Hwa-Nan’s field experience to discuss greenhouse structure, controlled-environment agriculture, and smart cultivation.
Open-Field vs. Protected Farming — In Taiwan, Count the Risk into the Ledger
Open-field growing saves the facility investment but stakes a whole season on the weather; protected cultivation buys stability of yield and price. In Taiwan, the risk belongs in the ledger too.
Before You Build a Greenhouse, Think It Through — About the Money
A greenhouse isn’t equipment you buy — it’s a business you open. Answer three questions before ground breaks: grow what, sell to whom, pay back in how many years.
Washing the Covering and Desilting the Gutters — the Maintenance Most Worth Scheduling
A dirty covering loses light transmission; a silted gutter turns every storm into leaks and standing water. Washing and desilting are one maintenance routine — and going up to wash the roof is the best chance to catch a leak early.
Getting Water and Power onto Farmland in Taiwan — Clear “Permitted Use” First
Hooking up water and power on farmland is never a mere phone call — it is tied to land-use legality, the purpose of the power, and permitted use of the facility. Here are the five categories of agricultural power, the documents you need, and the pivotal permitted-use consent.
Twelve Real Pain Points of Greenhouses in Taiwan — and What Design Should Solve First
Heat, humidity, typhoons, pests, cost, and regulation all pull against each other. This piece lays out the twelve most common field pain points and the five things design should nail before the first drawing.
Film, Netting, or Glass — Choosing the Right Greenhouse Covering
Film is cheap and quick to install, netting ventilates and excludes insects, glass transmits the most light and lasts — there is no absolute best, only what suits your crop and operation.
Why Early Planning and Design Is the Best Investment in a Greenhouse
A greenhouse’s most expensive waste is usually locked in before ground breaks — and can usually be avoided there too.
Why Good Greenhouses Use So Much Aluminium — and Why ESG Favours It
Corrosion-free, precision-formable, recyclable almost indefinitely, and one-third the weight of steel — Hwa-Nan’s own aluminium profiles, developed for Taiwan’s climate, make construction faster and safer.
Why Hot-Dip Galvanizing Is Standard for Greenhouse Structures in Taiwan
Hot, humid, coastal, and irrigated for hours a day — hot-dip galvanizing is the front line that keeps a greenhouse frame standing for ten or twenty years.
Why Greenhouses Deliver Stable, Sustainable Yields
On the same plot of land, why does a greenhouse harvest reliably year after year? The answer lies in two words: controlled environment.
What Taiwan Can Learn from the Dutch Smart-Greenhouse Model
A country smaller than Taiwan became an agricultural export power by making greenhouses that manage themselves.
