Greenhouse Lighting – All About Light in Protected Environments
Greenhouse Lightning – One of the Most Important Factors of Growing Green Plants Greenhouse lightning
is probably the most important aspect of growing green plants
. Plants use light for photosynthesis
, development and growth. In nature, green plants acquire their light from the sun. A greenhouse is no different. A greenhouse does have one advantage over nature, that being it is a more controllable environment. Most greenhouses will have some type of artificial or man made lighting system installed on the interior. These lights can be used to provide light during the evening hours when the sun is not present. Each Plant will respond to light in uniquely, so it is important to research the plants you plan to grow in order to obtain the correct grow light
settings. You can use common light fixtures to create light for your plants. However, you can use growing lamps and supercharge your greenhouse and the plants growing within. Growing lamps
are very effective during winter months because of the shorter days producing less sunlight. Growing Lamps will help increase the intensity of the light used to grow your plants by simulating longer days. Growing Lamps use Fluorescent light
to produce the light for your plants. These types of lights to not produce very much heat and will allow you to place them close to your plants. In nature, plants will maybe get between 8 and 12 hours of sunlight during the day. These hours are dependent on plant, its location, climate and surroundings.
GREENHOUSE LIGHTNING | Can Plants be Exposed to Too Much Light?
The answer to this is no. However they can be exposed to too much of the heat that is also generated by the growing lamps. If the greenhouse environment and plant tissue temperature becomes to high, the water that was ingested by the plant will be used to cool the plant cells and tissue. This will cause photosynthesis and other developmental functions to shut down, thus limiting the growing potential of your plants. If you plan on using your greenhouse lights as a type of steroids for your plants, make sure to keep your greenhouse as cool as permitted by the plants you are growing. Proper ventilation, humidity levels, and shade net
are all techniques that can be incorporated into your greenhouse to prevent any heat from your lamps from overheating your greenhouse. Once you have things in balance, these lights can be used to supercharge your plants and help you grow a healthy batch of fruits and vegetables. The growing lamps are equipped with reflectors that will redirect the light downwards, where it is most beneficial. In order to maximize the potential of your greenhouse lighting setup, it is recommended to install the lighting tubes twenty five (25) to thirty (30) cm above the plants. Light meters may be required when your plants require a strict light diet. The light meters will measure the light levels in the greenhouse, thus allowing you to adjust your lights and plants accordingly.
Greenhouse lighting and SCROG or SOG netting
Obviously the main consideration when using expensive artificial lighting inside a growing environment
is trying to maximize the exposure to the artificial and expensive light source by accommodating and supporting plants with SCROG netting
(screen of green
) or SOG net
(sea of green
) in such a way that even the smaller or slower growing plants are allowed the same quantity of light as each flower plant is confined within the space of the HORTOMALLAS flower net
