Reduced Pest and Disease Exposure
From large freestanding buildings to small window-mounted structures, a greenhouse is possible for almost any property. Although working in an outdoor garden allows you to soak in the sun, many prefer the controlled indoor environment greenhouses provide -- you are still productive in the garden on a surprise rainy day. And, plants tend to grow better in greenhouses compared to outdoors.
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.
