It is an inevitable fact that once you get keen on the growing business, you will immerse yourself into the focus of which is the best grow lights. It gets even more confusing since factions for either Led or HPS claim that the light works best for their cannabis plants.
Before making the conclusion which is better LED vs HPS grow lights, it is important to explore deeper into factors like growth stages, room to grow, efficiency and ease of use before making a verdict.
If you checked this debate five years ago, HPS grow lights would have emerged as clear winners of the discussion. However, the technology of LED lights has grown tremendously over the years, especially when it comes to its cost per unit efficiency.
This element then makes determining a clear winner between the two less obvious. As technology continues to improve, more and more growers are gradually adopting the LED lights. But the question is have LED lights finally outperformed their dominant competitors the HPS lights?
Here, we are going to delve into the conversation to determine the ultimate winner between the two dominant players in the grow lights market.
The old saying that there is no definitive setup but only suitable lighting further illuminates the matter on which is the better option between the two lights. The type of space you are using is a great determinant on the type of illumination to make use of.
For instance, growers with an eight by eight tent will find that despite wanting to go for an economical and efficient option, the light footprint emitted by an LED may not be adequate to cover every section of the room. Hence for big tent growers, the HPS grow light serves them better due to the enormous obtainable light impression.
The type of plant you are going for is a determinant on the choice between LED and HPS lights. For instance, if your plant is the Cannabis Sativa plant 6’, then you are better off with a horizontal lying light option like the LED lights.
On the other hand, if your plant is a bushy Cannabis strain, then you have to use a light bulb with a very strong lumen. In this case, an HPS light system will do the trick for you.
Depending on the temperature, a poor lighting choice can determine the success or failure of your operations. For example, in an already hot environment, going for a choice like 1000 watts HPS light is not a very good idea.
What you need is a light source that emits low heat like an LED bulb. This system will ensure that lumens are being effectively discharged at the same time, ensuring that there is no corresponding increase in room temperature to the extent of destroying your plants.
On the contrary, in a chilly environment, using an LED will not serve you any good. This fact is due to its low heat. What you want in this case is an HPS light which will warrant that not only are critical lumens being delivered to your plants, but also some heat which will raise the room temperature ensuring a conducive environment for plant life.
For cannabis growers, the choice of a light source has an impact depending on the growth stage of the plant. At this initial stage, the cannabis plants are quite vulnerable on their journey to becoming infantile floras.
If you make the mistake of introducing intense light sources, you will end up damaging the plant since it doesn’t have a strong enough footing to put up with such a powerful light.
The dimming selections and full range abilities of an LED are ideal at this growth stage. Similarly, their low heat emission is ideal and can be placed above the delicate seedling without risking the possibility of harming the plant.
Using an HPS is not recommended at this stage. If you have to use, then, place it way above the canopy in order to protect your seedlings from damaging heat.
This stage is very integral in cannabis plants life cycle. It determines the root system and growth process. Obtaining photosynthesis efficiency from a proper light source at this phase cannot be over-emphasized enough. The HPS system is the ideal light source at this stage.
This element is due to added wattage hence fostering an increased growth rate among plants. On the other hand, having the HPS lights will mean a high electricity bill since it requires more than 18 hours of light for the plants to perform optimally. Similarly, other growers may argue due to the efficiency of LED lights and low heat emission they are ideal for this stage of growth.
In order to enable a bountiful harvest, an appropriate light source is key. This stage is also what every grower longs for. Studies show that due to better response by the plants to the red and orange wavelength, HPS lights are ideal for this period.
The reason is the wavelength mimics the shift of the sun, which occurs during fall. On the contrary, the enormous amounts of Heat the HPS lights produce impedes the survival of the buds produced by the cannabis plants during the flowering stage. This element can hinder the harvesting of optimum yields.
The trade off of using LED lights in this phase is the risk of having medium to low yields. The use of these lights is mainly done by growers who are on a budget and do not want to frequently change the bulbs to acquire the proper wavelength.
The reason is many LEDs have the benefit of being digitally viable. Hence a person can choose an all-red spectrum which can be used as a substitute. In contrast, cases are seen where experienced growers are able to produce relatively high harvests while using LED growth lights.
Despite the HPS apparent straight forward nature in its use, it requires external ballasts, which have the inconvenience of noise making as well as weighing a lot. For this reason, it’s not recommended for a do it yourself initial setup.
The HPS systems also require hoods and installing this increases setup time as well as cost. Amateur setups of HPS can lead to disastrous perils like the likelihood of a fire outbreak occurring in your growth room.
Quite the opposite, LEDs are exceptionally easy to use, and a considered plug and play option. The other great features include being lightweight, having a digital menu, hence making them particularly simple to use. They take the title as the most user-friendly and ideal for beginners.
Here are the Pros and Cons of each type of light.
The choice between LED vs HPS growth lights rests on you. To make this informed decision, you need to understand every facet of your environment, since every grow is different. Otherwise, from a technological standpoint, LED grow lights are superior and present a strong lead to the planters in terms of ease of use, efficiency and better results.
