Incentive payments from the USDA’s Natural Resources Conservation Service or Environmental Quality Incentives Program, or a State Farm Energy program can help defray the installation costs.

An economic recovery is a business cycle stage following a recession that is characterized by a sustained period of improving business activity. Short of building specialized structures for growing mums outdoors, think creatively about how you can use your existing space. For indoor grow rooms, sizing the HVAC system is critical to handle the heating and cooling loads you will get once you start growing plants in those rooms. Fans located too high above the crop do not provide enough air movement within the crop, but fans located too close to crops will adversely affect your ability to manage moisture levels. Controlling air temperature with enough air movement and dehumidification can be hard to do when you are also trying to get the most plant density out of every room. She is a licensed Mechanical Engineer in California and received her Ph.D. in Agriculture and Biosystems Engineering from the University of Arizona’s Controlled Environment Agriculture Center (CEAC). Expansions last on average about four to five years but have been known to go on anywhere from 12 months to more than 10 years.

Money flows freely through the economy, companies take on loans to fund expansion, job prospects improve and consumer spending rockets.

Like the weather, the economy is believed to follow a circular path that continues to repeat itself over time. Properly size your HVAC system. Use shade curtains during high-light and high-temperature months. Tests show that it will have about 45% energy savings. Ventilation is the process of exchanging indoor air with outside air. When positive displacement MV relies on introducing outside air to condition the greenhouse without recirculation back to an air conditioner or climate control chamber, it is important to consider how the air will leave the greenhouse. Most of these new houses have one or more energy curtains to insulate the roof area, resulting in the heat loss through the walls being greater than through the roof. When the economy is growing, customers are buying and borrowing costs are cheap, management teams regularly seek to capitalize by ramping up production. If the above house was glazed with double polycarbonate it would require about 428,000 BTU/hr for the uninsulated wall area and only 309,000 BTU/hr for the roof area with a double screen on a night with a 60° F temperature difference between inside and outside. A trough, in economic terms, can refer to a stage in the business cycle where activity is bottoming, or where prices are bottoming, before a rise. Most commercial greenhouses are equipped with the ability to do both NV and MV, whereas some are only able to do one or the other. If there are no vents in the roof, this hot air will be trapped in the ridge space with nowhere to go. Stressed garden mums are more prone to form premature buds, especially when exposed to cool temperatures. Negative displacement is the more traditional method of MV used in greenhouses. It is generally better to have both NV and MV available, so that adjustments can be made in response to changes in the crop and the climate. Applying up to 500 ppm ethephon work well for garden mums.. For pinched crops, wait a week or two after the pinch occurs.

The author is founder of Dr. Greenhouse, an engineering consulting firm that specializes in the design, specification and analysis of environmental control systems. There are two common types of curtain materials that will provide good energy savings.
