The warming weather is a reminder to greenhouse owners to examine climate control strategies inside the structure so as to ensure crops grow strong and healthy throughout the warmer days and nights ahead. Without such consistency, plant damage and even death can occur.
The experts at Gothic Arch Greenhouses, a family owned and operated greenhouse and supply business for nearly 70 years, can partner particular circumstance with quality, affordable, easy to use equipment needed to help ensure optimum climate control inside the greenhouse.
“It boils down to three things,” says William H. “Buzz Sierke, third generation president of the Gulf Coast based business, “correct lighting, temperature and humidity. To know those, you first must know what conditions are needed for the particular plants being grown in the greenhouse.” Sierke encourages all growers, commercial or hobbyist, to think about where a particular plant originates. Take ornamentals and tropicals for example.
Ornamentals can tolerate nighttime temps as low as the mid-50’s while that temperature can damage tender tropicals that don’t want it below 60 degrees. On the other hand, temperature needs for successful seed germination varies as do those of cool or warm weather vegetables. “It all depends on what you’re trying to grow, and under what circumstances,” Sierke says.
Rising temps means higher humidity which, for some crops like Tropicals, is good, for others like some ornamentals, it could be deadly. If the circumstance calls for decreasing humidity levels inside the greenhouse, venting or exhausting the humid air is in order. That means air movement. A closed greenhouse needs a fan to blow hot stale air out of the structure and bring fresh cooler air inside via intake shutters mounted on the opposite end of the structure to create consistent environmental control.
Gothic Arch Greenhouses offers a huge selection of greenhouse ventilation fans like our favorite, the Air Flow HAF fan, a specialized greenhouse fan that allows adjustable air patterns to create a uniform temperature throughout the structure to suit any growing need. According to Sierke, the Air Flow HAF is by far, the most versatile, energy efficient, best valued HAF fan available.
For larger greenhouses, Sierke says the same optimum growing conditions can be maintained by using greenhouse cooling system which utilizes the hot air inside the greenhouse to evaporate the moisture from plant surfaces thus cooling the inside temps by up to 20 degrees.
Whatever environmental control system you choose, you’ll need control. Arch Greenhouse can help you choose from a wide selection of the most reliable automatic one, two, or manual variable speed thermostat controls available on the market today, designed especially for greenhouses.
And no environmental control plan would be complete without a timer to give freedom over how much or how little light plants get and when. The right automatic timer allows control over automated watering and mist systems, fans, heaters, and other equipment too, allowing one time for other activities.
So, as the days grow longer and warmer, take the time now to plan how to create and maintain consistent optimum growing conditions needed for successful healthy plant growth inside the greenhouse during the days ahead. Gothic Arch Greenhouses is the most trusted name in greenhouses with over 70 years of dependable service providing made in the USA, do-it-yourself greenhouse kits, related accessories, and the right environmental control systems to fit any need.
Most of the greenhouses in the Netherlands are so-called Venlo greenhouses. This construction is strong, allows a lot of light to pass through, is relatively inexpensive. The Venlo greenhouse is ideal for the Dutch climate conditions. But which design fits in another climate, such as a desert or a humid climate? The Greenhouse Horticulture & Flower Bulbs Business Unit of Wageningen University & Research developed a method for designing one based on local conditions: Adaptive Greenhouse Design. An interactive tool demonstrates the operation and benefits of this method.
