Ornamentals demand the most precise climate steering of all crops

Cut flowers and pot plants are among the most demanding crops a greenhouse can grow, because with ornamentals the product is its appearance. A vegetable can carry a small blemish and still sell; a flower cannot. Stem length, straightness, colour, bud formation and vase life are all judged directly by the buyer, which means the climate has to be steered with a precision that leaves very little margin — and that precision is exactly what high-tech Dutch greenhouse growing was built to deliver.

Above all, flower cultivation runs on photoperiod. Many ornamentals flower in response to day length, so growers use blackout screens to shorten the perceived day and grow lights to extend it, steering the crop into flower precisely when the market wants it — for the peaks around key selling dates rather than whenever nature would allow. This control over timing is what turns flower growing from a seasonal gamble into a plannable, programmable business, and it is why the light plan sits at the centre of every flower greenhouse design.

Around that light plan, temperature and humidity are tuned per variety to protect quality. Temperature strategy influences stem length and the pace of development; humidity and VPD control keep transpiration steady so stems stay strong and calcium-related defects stay away; and careful climate management in the final phase protects the colour and the post-harvest vase life that determine what the crop is ultimately worth. Screening also manages the radiation load so blooms are not scorched or faded. Each of these levers is set to the specific needs of the variety in the house.

From roses and chrysanthemums to gerbera, lisianthus and potted ornamentals, our facilities are engineered around the light plan and climate profile of the specific crop, then supported with the cultivation knowledge to run them. The result is consistent, market-ready quality delivered to the calendar. Get in touch to discuss a flower greenhouse built around your crop and your market.
