Just like humans, plants need light, and there are those plants, esp. the hydroponic ones that need specific light. The grow light system of Marijuana enables you to lengthen the growing season by means of an indoor light equivalent to daylight. This is beneficial for those who have a one year supply of fresh veggies, herbs and flowers. Furthermore, artificial lighting is also a way to accelerate spring through seedlings in advance. There are 3 major types of lighting systems.
Approximately three thousand lumens per square foot are the minimum requirement of light needed by marijuana plants. But it is not 100% accurate because it varies the distance between plants and lights. 7000-10,000 lumens/sqft is the ideal amount. As long as the plants are safe and does not get burn. Take note that during summer, light produces 10,000 lumens/sqft.
Compare to incandescent, Fluorescent Grow Lights are more useful because of its efficiency, and cheaper in price. Due to its excellent output and size ratio, fluorescent tubes have become popular with growers. Fluorescents work best in small Marijuana plants and those who are on tight budget. Since they do not need special understanding or wiring of the bulbs for a particular fixture, and because they are widely available, they are the best option for novice growers. Fluorescent lights for growers come in different Kelvin ratings. The spectrums on packaging are often labelled as ‘warm white’ or ‘cool white.’ The latter is bluer, therefore good during vegetative stages, while the warm white light comes with reddish or orange, and work best during flowering stage. Warm light is also perfect for seedlings and starts.
When it comes to popularity, incandescents have become the most popular light types in the world. On TV or journals, they are advertised as tungsten, incandescent, quartz, simply standard or halogen. It is important to note that there are incandescents advertised as ‘grow lights.’ Incandescent lighting comes with blue coating and is available in sizes of 60W and 120W. They are so good for seedlings and since they do not need ballast, they are an inexpensive alternative for growers. They are the best option for all those farmers who are beginners in this field.
High Pressure Sodium Lighting
This type of light emits mostly yellow, orange, and red spectrum lights, which are ideal during the flowering stages of plants growth. According to expert’s opinion, they are the most efficient light available because they can be used throughout. They have larger buds and are denser than any other lights. Generally, they are more expensive but are very durable. They are the best choice for experienced growers because of their capacity to generate higher tighter buds, and lumen-output-per-watt.
High Intensity Discharge Grow Lights
Mercury Vapor Lighting: This type of light is not the most proficient light for growing. But, they are extremely bright, and fairly cheap. Of course, they emit light at wavelengths needed to support on plants growth. The commonly used light emitted is bluish-white by MV lights. Usually, the street lighting is the most commonly used in MV lighting.
Metal Halide Lighting: In the vegetative phase, this type of light is optimal for use. Usually, they emit blue light as it encourages energetic foliage growths. They are efficient, but can be expensive for starters. Hence they are a good bet when you are an experienced hydroponic farmer and know all the ropes and are very sure about the whole ins and outs of the process.
Whether a beginner or an experience grower, it is very important to know the different type of lights because hydroponic Marijuana grow lighting has very specific requirements.
Hydroponics is a type of horticulture that is grown using a unique method of mineral solutions. For instance, plants that grow on land may be grown with the roots deepened inside salt solutions. When mineral solutions dissolve in water, the plant roots are able to absorb and utilize them for quick growth. Research has proven that all terrestrial plants are able to grow with hydroponics. To determine the amount of heat that this plant requires, you should put your hand on top of the plant gauge to see whether the heat is too much.
In case you are growing hydroponics for the first time, it is very important to use the grow light as much as they require. Fluorescents may look strong, but their intensity requires them to be put closer to the plants for them to work well. If at all you have more cash to spend, you might consider using the HPS, which creates a lot of heat, but generates a lot of intensity that the plants needs. When using the HPS with any source of light, ensure that they are not very close to the plants as this might end up affecting them much.
How much light do I need to grow lettuce plants?
Lettuce plants do not require a large amount of grow light. The good thing about this plant is that so long as it has been kept alive, it does not matter how big, or small you grow it. The best advice is to purchase a bulb that is 40 watts or less, since if you use more than this the plant is likely to go bad after 8 weeks. In colder environments, where the air inside is drier, results are often better when growing the plants. Moreover, remember to place the light about 30cm from the plants to get good results.
However, some people have had success with 80 watts worth of light. With this kind of light, you can grow at least 6 types of plants and reap well. Apparently, if you want to start your seeds, Compact Fluorescent Light (cfl) is just a great way to start them. The amount of light that they produce is suitable. Make sure that you determine whether the plant require 400, 600, or 1000 watts.
