Like every other plant’s growing requirements, weed necessitates various essential aspects for its nourishment. From favorable humidity levels to sufficient day or night temperature and carbon dioxide supply, they all play a significant role in the sustenance of a weed plant.
Besides all these factors, lighting is also a major requirement. Essentially, if you want to grow weed then you need to take this into extensive consideration.
But what kind of light is best for growing weed? Well, certainly some light types are more suited for cannabis growth than others.
In this article, we shall discuss such lights providing you an insight which in the long run will help you make a shrewd decision on which lights to use to grow your cannabis. So with no further ado let's take a look at the different options available and the pros and cons of each.
1. High-Intensity Discharge Grow lights
This light brand provides one of the most preferred bulbs among most weed growers. They are highly effective and result into highest yields per portion of grown weed.
Lamps in this category are used together with a reflector to increase light intensity reaching the plants. Due to their high heat generation properties, you can connect an exhaust to provide cooling effect hence preventing from blowing out.
HID bulbs are further subdivided into the following categories.
- High-Pressure Sodium lights: Their light is pale yellow and is typically suitable for growing weed during the flowering stage. This kind of light nurtures bud growth, which eventually increases the overall production.
- Metal Halide lights: Bulbs in this category produce blue light that is favorable for vegetative growth of weed. Well-nourished leaves help grow a healthy plant, while the eventual produce is boosted. In case of limited resources or other factors that prevent you from changing to HPS grow lights during later development stages, you can still use this bulb for the entire growth period.
- Light Emitting Ceramic/ Ceramic Metal Halide lights: These bulbs are suitable for the general growth of weed, although they are mostly preferred as an alternative to metal halide lights. They are more efficient hence result in higher yields and better quality.
Advantages of HID grow lights
Below are some of the benefits associated with High-Intensity Discharge lights.
- Convenient to use since they do not require regular shifting once you hang them above your weed plants.
- Highly efficient since different bulbs in the same category specialize for a particular function hence assuring you high yields.
Disadvantages of HID grow lights
- Complicated set-up due to the inclusion of several parts such as exhausters and reflectors.
- They generate much heat whose cooling process demand additional expenses. Besides, if excess heat reached the plants, it would cause significant damage and reduction of yields.
2. LED Grow lights
This type of grow light bulbs is suitable for use for the entire growth period. However, its light is most useful during the flowering stage and is often used as a substitute to HPS grow lights.
The reason why these lighting systems are mostly preferred is due to their operation while still maintaining cooler temperatures. Therefore, there is no need to install an external cooling mechanism, and besides, they have in-built coolants.
Due to its high penetration properties, LED lights do not require reflectors as they reach weed plants adequately. However, they yield lowly as compared to other types of lights mostly due to lack of sufficient heat within the growing atmosphere.
For that reason, you might have to provide additional heat externally to the plants for increased production.
But if you aim at minimizing power consumption, then this kind of light is perfect for you since it provides a low consumption rate while keeping yields at a relatively elevated level.
Advantages of LED lights
- Although there exists no sufficient proof, this light is presumed to produce gummy buds, especially when used together with HPS bulbs. Such buds contain more active compounds hence increases weed effects on the user.
- Due to their size, you can easily hand then on the walls without complex support mechanism.
- They have an in-built cooling mechanism hence operate at low temperatures thus do not necessitate for coolants. Exclusion of coolant mechanism reduces costs as well as saving on energy.
Disadvantages of LED lights
- Since this light has a high penetration rate, the size of space required between them and weed plants necessitates for a sizeable room with high rooftops.
- Comparatively, the resultant yields are low for this kind of lights and require a constant upgrade in regards to wattage ratings of the bulbs in use.
3. Fluorescent Grow lights
These light types are the most commonly used among weed growers. They are highly efficient, while the amount of light intensity they produce does not affect humans when working in the farms.
Fluorescent bulbs are available in various forms and shapes which matches different growth stages.
Here are some types of available fluorescent lights.
- T5 fluorescent lights: These kind light a large while they come in the form of panels packed with several tubes in them. They are used in most improvement-based indoor farms while they are suitable for all types of weed plants.
- CFL fluorescent lights: They are smaller twisty bulbs that are suitable for smaller farms. Their light band is excellent for various types of wed plants while they yield highly.
Advantages of fluorescent lights
Here are some of the benefits associated with fluorescent lights.
- They are suitable for small scale farming while the distance between them and the plants can be kept short.
- They are cheaply available and consume low amounts of power.
- They are great for young weed plants, especially grafted ones due to their low heat generation. Excessive heating would burn weed seedlings and young plants.
Disadvantages of fluorescent lights
- They have a low penetration rate hence cannot be used in large farms. Besides, they are only suited for lowly-growing trained plants.
- They result in trivial yields due to their low spectrum power, unless supplemented with other light types during the budding stage.
While some farmers may consider solely providing nutrients to weed plants as the ultimate enhancement to high yields, a good weed grower understands the essence of good lighting.
Since most weed growing is best carried out indoors, you should consider acquiring a suitable, preferred kind of light for guaranteed high produce.
