Flowers are the least forgiving crop in any greenhouse, because a week of poor light or trapped humidity shows up directly in bloom grade and price. This house is built around those two variables: UV-resistant PE film passes 92% of daylight while blocking the UV that bleaches petal colour, and side openings with insect nets and roll-up curtains bring humidity down quickly on warm days. The frame is hot-dip galvanized steel, with the film locked into a grooved channel by aluminium clips so the cover stays put in wind. Spans run from 8 to 18 metres in single-span or multi-span form, and drip irrigation and shading can be fitted before delivery rather than improvised on site.
Cut flowers are graded on appearance, and appearance is a running total of everything the house did to the crop. Light that arrives unevenly makes stems that will not bunch; humidity that sits in the canopy costs petals to botrytis and leaves the grower sorting out losses at packing time. A flower house is therefore a light and air problem before it is a structure problem.
The UV-resistant polyethylene cover passes 92% of available daylight while filtering the UV that bleaches petal colour, so blooms hold their market look through the season instead of fading toward the end of it. Passing more light is only useful if it arrives evenly, which is why the cover is tensioned flat across the arch rather than left slack: an even roof gives even colour, and even colour is what makes a crop grade as one consignment rather than three.
Roses and lilies are sensitive to moisture, and still, humid air is the condition botrytis needs. Side openings fitted with insect nets and roll-up curtains let the grower bring humidity down fast on warm days without letting pests in, which is the difference between clean stems and a lost run. Ventilation is specified at order stage so the opening area suits the house volume and the crop, not the other way round - comparable houses that vent from the roof are covered by the ventilated greenhouse range.
The frame is hot-dip galvanized steel for rust resistance, and the covering locks into a grooved channel with aluminium clips so the film holds through wind instead of being tied down. The galvanized frame is rated for a 15-20 year service life and backed by a 10-year structural warranty. Spans run from 8 to 18 metres; a single-span house suits a small flower plot, while commercial nurseries usually take the multi-span form so walls and climate systems are shared between bays. Span and ridge height are set from your crop rows.
Drip lines keep water off petals and foliage, and shading controls the summer light peak; both can be pre-fitted before delivery. Watering is normally specified with the house so the manifold and pipe runs sit in the right place - the drip irrigation package covers the common layouts. Roses, lilies, orchids, gerbera and bedding plants all work in this house, and so does potted stock, so the fit-out follows the crop rather than a fixed recipe. Growers comparing flower houses can start from the greenhouse for flowers range.
We have delivered greenhouse projects in 27 countries, and flower houses demand more precise climate control than most crops. Every arch pipe end carries a stamped BZ mark, our anti-counterfeit sign, so replacement parts years later are traceable to our plant. The package covers the metal structure, the covering system and the installation accessories, and our engineers can travel to site to supervise assembly. Standards for greenhouse structures are published by NGMA, and protected flower production is covered by VerticalFarmDaily.
Roses, lilies, orchids, gerbera and bedding plants all do well, and potted stock suits it too. The even light transmission and the adjustable side ventilation are what most cut flower and pot plant crops need, and the fit-out follows your crop rather than a fixed recipe.
Yes. The UV-resistant PE cover is rated at 92% light transmission, and the figure is confirmed against the film specification before shipment. Tell us your crop and climate and we will recommend the covering and the layer count.
The hot-dip galvanized steel frame is designed for a 15-20 year service life in normal agricultural environments, with a double-sided zinc coating of 200-275 g/m². Film covers are replaced every 3-5 years, while glass and PC panels carry their own manufacturer warranties.
The hot-dip galvanized steel frame carries a 10-year structural warranty covering structural safety, plus a 5-year warranty against corrosion perforation. It is designed for a 15-20 year service life, and the covering film carries a 3-5 year UV warranty depending on material type.
Send your flower types, field size and local climate, and tell us whether you want drip irrigation and shading included. With that we can confirm the span, the covering and the venting, and return a layout and quotation with a bill of materials.
