In Maasland, the Netherlands, is a region the Dutch call “glass city” because of the many greenhouses that produce roses. In Columbia and Ecuador, hundreds of thousands of workers plant, harvest and ship most of the 4 billion cut flowers purchased in the U.S. South American flowers are used because California and Florida, the largest flower growing states, can only satisfy about 10% of the Valentine’s Day demand.
Overall, about 200 million rose stems will be purchased in the U.S. alone for Valentine’s Day, with millions more in other countries that celebrate this holiday with the gift of flowers.
What do all these roses have in common?
First, most roses today are grown in modern, climate controlled greenhouses. By accurately monitoring the water, temperature, fertilizer and carbon dioxide levels, rose growers have been able to reduce pesticide use.
To add CO2 inside a greenhouse, propane burners are often utilized. To balance the cost of fuel with the CO2 needed to grow the roses, products like our aSense GH Wall transmitter or our iSense CO2 Level Controller are used by greenhouse growers.
To further reduce energy costs, some greenhouses are being built next to power plants, where they can easily pipe in the excess CO2 produced by the plants. This exchange of CO2 becomes a win-win for both industries and insures better products for consumers.
