A greenhouse needs to be set up in a way that it provides the proper environment for plants to grow.
One of the of the most important factors in plant growth is lighting.
Sun or Shade
It’s important to remember that not all plants need the same amount of sun. Some need full sun, while others need partial shade. When choosing the perennials, shrubs, and grasses for your greenhouse, you need to learn which type of sun conditions they would thrive in when planted outdoors.
You can then divide the plants into groups based on their lighting needs. This will allow you to organize your lighting system so that each plant gets the amount of light it needs. While the plants are growing you should continue to monitor their growth, in case you have to make changes to the lighting.
Light and Heat
Your greenhouse lighting will emit a large amount of heat unless you buy lighting that is specifically designed to be low in heat-emission. This heat can actually damage your plants if you’re not careful. However, you don’t want to eliminate the heat because, for some plants, it is needed for growth.
Since perennials, shrubs, and grasses are long-term growing projects, you should continually monitor the growth of the plants to ensure the proper distance is maintained between the plant and the lighting system. As the plant grows closer to the light, it may be damaged by the heat.
The lighting you choose should be movable or adjustable. This means you can either raise or lower the lighting if needed, or lower the light level, thus reducing the heat. However, you need to ensure that the plant is still getting the proper amount of light, in order to maintain its health and help it grow.
Natural or Artificial Light
In a greenhouse it is possible to get some natural light, however, this light is seldom enough for most plants. Lighting is available that replicated natural lighting, however, this type of lighting can cost more than standard greenhouse lighting.
When you look for lighting make sure you try to get lighting that offers light that is as natural as possible. This will help the plant when you finally remove it from the greenhouse and it is placed outdoors.
Since a perennial, grass, or shrub may be in your greenhouse for months or years, the lighting for these plants requires more of an investment of time and money than for your standard annuals. If these plants die you’ve lost a significant amount of your time and effort.
Look for the best lighting options you can afford. Talk to the people at your greenhouse supplier or with other gardeners who have greenhouses. They can be a great source of information and can help you determine which lighting would work best for the types of plants you want to grow.
