Ways to reduce greenhouse energy consumption

January, 17th, 2019

Canadian greenhouses are expecting a harsh winter in terms of energy. Rates have been steadily rising for years, but the explosion of the Enbridge natural gas pipeline in British Columbia may be the final straw, as B.C. growers are now facing a shortage of up to 50 per cent during the coming winter months. In order to remain in business, and just as importantly, profitable, greenhouse growers should consider improving energy efficiency, rather than relying solely on alternative energy sources

Luchtontvochtigingsunits nu ook op frames voor boven het gewas

February, 10th, 2019

Het inzetten van DryGair werkt op twee fronten. Ten eerste wordt de kaslucht ontvochtigd, waarbij geen koude buitenlucht benodigd is.
Ten tweede wordt de kaslucht door de ventilatoren goed vermengd. Hierdoor ontstaat een egaal klimaat en zijn er geen koude hoeken meer. “Dit actieve klimaat leidt tot weerbare gewassen. Gebruikers zeggen regelmatig: ‘Met DryGair heb ik een stuur in handen.’”

Greenhouse Heating, Coal & Dehumidification – A Breakdown

December, 26th, 2018

Heating a greenhouse is one of the most basic aspects of modern agriculture, yet the methods in which this heat is produced may seem a bit antiquated, even in countries considered to be at the forefront of both technology and environmental awareness. There are endless ways to improve the environmental footprint of modern agriculture. New greenhouse technologies may allow growers to focus on reducing the need for heating, thus reducing fossil-fuel consumption, as well as expenses, instead of searching for the next cheap energy source.

Surviving the Winter in a Greenhouse

January, 1th, 2019

Growing in a greenhouse is great because it allows a grow to harness the natural energy of the sun. The sun’s light heats up the greenhouse, while providing full spectrum lighting, free of charge, all day long. But when winter rears its cold head, the tide shifts, and the concrete walls isolating a warehouse operation suddenly seem pretty warm and cozy.

We put together a few tips for surviving and thriving during the cold season, between see-through walls.

The Energy-Humidity Connection

Energy is a major factor in modern agriculture. As we moved away from the plow and hoe and into the world of tractors, irrigation systems and eventually lighting and HVACs, we’ve improved yield quantities, gained the ability to bypass climate limitations and arguably improved the quality of our crops. But all this has come at a price – massive amounts of energy are poured into these operations in order to maintain optimal conditions for our precious plants.

Ask DryGair: Ventilation VS Dehumidification

Growers in closed facilities face complicated challenges, one of the more complicated challenges being humidity.Humidity inside a growing facility is generally caused by transpiration from plants. If humidity gets too high, drops of water form on the plants, causing humidity-related diseases such as Downy mildew, Botrytis, Alternaria, Powdery Mildew, Erwinia, Phytophora, or Clavibacter. Reducing the humidity inside growing facilities can prevent diseases and reduce the need for pesticides

A new technology aimed at greenhouse dehumidification

DryGair explains HVAC systems and their uses in a growing facility. Is it appropriate for your grow?

DryGair explains how temperature is influenced in the grow space, and the ideal temperatures for cannabis cultivation.

All growers must contend with high relative humidity (RH) in their greenhouses. This has motivated DryGair and the Israeli Agricultural Research Center to seek a solution to this issue.
The concept was developed by an engineer, Avraham Arbel, of the Agricultural Engineering Institute at the Israeli Agricultural Research Center (Volcani Center) in Beit Dagan.
It provides advanced solutions to overcome the high RH issue. High humidity inside greenhouses often triggers fungus and bacteria-based plant diseases, which can spread rapidly and damage yields.

You’ve probably encountered HVAC systems. HVAC is an acronym for Heating, Ventilation, Air Conditioning. They’re virtually everywhere: air ducts lacing supermarket and warehouse ceilings, bulky equipment outside or atop office buildings and sports stadiums, or furnaces sitting in the garage or basement of your home. HVAC systems are found commonly in our lives and are there to provide comfortable indoor environmental conditions in the form of temperature and air quality. Studies conducted in office buildings showed that ambient indoor air temperature as well as indoor air quality have significant effects on the productivity and well-being of workers. *

One of the most crucial factors influencing cannabis growth is temperature. Temperature plays a vital role in a plant’s growth processes such as photosynthesisand transpiration, which are responsible for the plant’s physical development and nutrient uptake. Temperature is also crucial in the production of a cannabis plant’s resins and terpenes. This impacts the quantity, quality, and composition of the final product. Growers in closed growing spaces need to maintain temperatures within optimal ranges for ideal growth.

“DryGair gives grower the reins”

Elad Spiegel, Director of Cultivation for Golden Leaf Holdings

Reducing humidity while saving energy

Less than two years ago, the first units were installed in a Dutch greenhouse. Then another, and again another one, and yet another. Now, more than 50 units have been installed at over 30 companies in the Netherlands. “It’s all I do now,” says Eef Zwinkels of Royal Brinkman. The company started a partnership with Israeli developer DryGair a few years ago. The dehumidification technology is effective, sustainable, and give the grower the reins.

The best way to prevent fungal pathogenesis is environmental control. While fungicides work to a limited extent, you greatly sacrifice quality, and the effects are limited over time, as the fungal population will eventually develop resistance to the fungicides. More effective fungicides will have a negative impact on your laboratory tests and will greatly lower the quality of the cannabis. As a result, fungicide use is unsustainable for a commercial cannabis grower, because you will not be able to sell your product.

Growing flowers in greenhouses is a very common growing method, and popular flowers such as Gerberas, Lilies, Tulips, Roses, Orchids, and Bromeliads are grown in greenhouses. There are many challenges the grower faces when growing in a closed space; a major one is a high humidity.

Using energy to positively influence the climate

Cannabis Technology, Policy And Global Innovation Is Lit At CannaTech 2017

Dehumidification units transform any operation into a semi-closed system

Energy and climate are connected.
We influence the climate through energy without meaning to.
Since the industrial revolution, the increase in energy consumption led to a rise in the anthropogenic heat (heat generated by humans’ activity), local environment temperature and humidity…

Another interesting example was DryGair, which reduces the humidity and controls the temperature inside cannabis commercial growing facilities. The technology allows growers to control the growing climate conditions and to create uniformity; to improve yield (quality and quantity); to reduce the need for pesticide and fungicide and to save energy.

Closed and more recently, semi-closed greenhouse growing are much discussed new ways of cultivating as efficient as possible. While depending on the location and application the system has a lot of major advantages over traditional greenhouse growing in terms of energy saving and crop enhancement,  the high investment is sometimes still preventing growers from making the switch.

What Cannabis Growers Need To Know About Humidity

The overall acceptance and technological development and innovations in horticulture might be sped up by the burgeoning medical marijuana industry in North America. There is a growing interest in horticultural technologies, know-how and products, and cannabis entrepreneurs do not hesitate to spend their capital. It seems like the entire horticulture industry, including flower growers and producers of edibles, can benefit from the know-how that the  cannabis industry gains while experimenting with new technology.

Een reuzenvochtvreter in de kas bij cherrytomatenteler Robert van Koppen in Kwintsheul zorgt ervoor dat de RV niet meer boven de kritieke waarde van 95% komt. Het principe is simpel: wanneer vochtige kaslucht langs de koude ribben van de ontvochtiger wordt gezogen, condenseert de waterdamp. Net als het condens dat zich vormt op een koud flesje bier wanneer je dit uit de koelkast pakt. De behandelde droge en iets warmere lucht gaat de kas weer in.

An increasing number of cannabis growers have advanced from growing in small rooms to commercial growing inside greenhouses. Greenhouse growing allows them to increase their yield, enjoy the outside sun (the greenhouse is transparent), control the growing conditions and save some energy required for lighting. Despite all the greenhouse advantages, the path toward better production has its difficulties, one of the biggest offenders is the humidity.
