Posted on: August 26, 2011

A greenhouse can proved to be a good and ideal place to grow many plants including orchids. Light, temperature and humidity are some of the conditions which can be maintained very easily in a greenhouse. Greenhouses are of different types and sizes so before purchasing a greenhouse, you should be sure that you understand the conditions which you are going to provide to your orchids.

Light

First element which needs special consideration is light. You will have to control light conditions in your greenhouse according to the type of orchid you have grown. For example, Cattleya orchids like sunlight while Phalaenopsis orchids require bright light but not direct sunlight. They like to be placed in west. In general, orchids should be placed in an area where they can get six hours of light but not direct sunlight.

Temperature

Since orchids are tropical plants, they need heat and humidity to thrive and both of these elements are present in a greenhouse. To make orchids bloom, you will have to make sure that temperature in greenhouse varies. Orchids will bloom only if there would be a difference of 10 degree F between day and night temperatures. For maintaining such temperatures, you need to have a thermometer in your greenhouse so that you can take readings and adjust temperature accordingly.

Humidity and Ventilation

Orchids like to stay in humid conditions but they do not like to sit in water at all. Water should not pool up in leaves or in soil as it may result in diseases like rot and fungi. Moreover orchids need good air circulation so place a fan near your plants. But fan should be kept clean to avoid spread of diseases from one plant to others.

Fertilization

Orchids need to be fertilized one time a month whether orchids are grown in gardens, greenhouses or in the house. Orchids should be fertilized by a fertilizer having equal amounts of Potassium, Nitrogen and Phosphorus.

These are some necessary requirements or conditions which need to be fulfilled to grow orchids in greenhouse. Growing orchids in greenhouse is beneficial as it allows you to grow plants throughout the year. So control above given conditions in greenhouse and have a healthy orchid greenhouse to provide you pleasure in your leisure time.
