Temperature Control

Outdoor temperature swings range widely between day and night. Plants subjected to extreme cold and heat across a 24-hour period do not grow as well as greenhouse plants and stressed plants become stunted over time. The enclosed indoor space greenhouses provide is typically temperature-controlled with heaters and air ventilation for specific plant species, such as food crops. Timers connected to the heaters allow you to alter the temperature settings depending on the time of day. By following each plant species' temperature preferences, foliage, flowers and fruit flourish throughout the controlled space.

Carbon Dioxide Factor

Controlling indoor air movement provides the greenhouse plants with a constant supply of carbon dioxide, which they need for sugar production. Although outdoor plants have sufficient carbon dioxide levels, strategically placed horizontal fans throughout a greenhouse allows air to press closer to the foliage for peak photosynthesis action. The concentrated carbon dioxide results in larger leaves, stronger plant stems and possible early flowering and fruiting. However, air movement must be coupled with proper ventilation. Closing off the greenhouse to outside air circulation lowers indoor carbon dioxide levels because the plants use the gas quickly while transferring oxygen to the air in exchange.

Reduced Pest and Disease Exposure

Plants in greenhouses grow in containers with specifically chosen soil. Unlike an outdoor garden, your greenhouse container soil does not have the potential of harboring harmful diseases and pests. As a result, your greenhouse is practically sterile to fungi, bacteria and pests, such as borers. Without stressful pathogens and pests, the plants concentrate on healthy growth rather than repair and defense.

Considering Humidity

Plant foliage transpiration relies on a constant supply of moisture from both the roots and surrounding atmosphere for peak growth. Dry, outdoor conditions force plants to rely solely on soil moisture, which can cause water stress, especially if the roots are in drought conditions. Stunted growth and reduced resistance to pests and diseases occur when dry conditions stay constant for an outdoor plant. But greenhouses with humidity controls keep the air moist for peak plant growth. Reducing water stress by watering the roots and providing a humid environment allows each plant to concentrate its energy on fruiting and flowering.

There are many factors to consider when cultivating inside a greenhouse. We have been cultivating in greenhouses for many years and also maintain relationships with very large greenhouse cultivators from the agriculture industry to assist in greenhouse layout and design as well as work flow, cooling systems, heating systems, blackout systems, and many other systems. Our focus is not on building you the most expensive high tech greenhouse, but assisting you on keeping your cost low, greenhouse quality and production high.
