Why is HPS lightning still popular in the UK despite the LED advances?
HPS are high-pressure sodium lights, and they remain a standard in many UK commercial greenhouses. This is because it offers high intensity, is effective for year-round farming and provides an additional radiant heat during the cold season, which is not possible through LED lights.
What is the difference between single-ended and double-ended HPS lamps?
The major differences between them are that double-ended HPS lamps are 25 to 30 per cent more efficient, brighter and last longer than single-ended lamps. This is because double-ended lamps are supported at both ends, which allows uniform heating and more stable output, making it ideal for maximising heavy fruiting crop yields. For the best quality, you can buy double-ended HPS lamps from a reputable company in the UK.
Do I need a special ballast for HPS Lights?
Yes, HPS lights require a specific ballast specifically designed for high-intensity discharge lighting to regulate voltage and current. You cannot use unregulated household power, as the ballast acts as an engine of a lightning system. To prevent any damage, the ballast must perfectly match the HPS bulb’s wattage.
Which plant stage is best for HPS lights?
HPS lights are superior for the fruiting and flowering stages due to their orange spectral output. This warm light encourages bud development and heavy yields.
Can I use HPS lights for vegetative growth?
Yes, but they may cause plants to stretch compared to blue-spectrum lamps or LEDs. The lack of blue light makes them less ideal for vegetative growth.
How far should I hang HPS lights from my plant?
The most optimal distance is 30 to 60 centimetres for a six-hundred-watt light, but it depends on the wheat output. You can check it by performing a simple test by placing your hand at that distance from the light; if it is comfortable on the back of your hand, it’s a safe distance.
How often should I change my HPS bulbs?
These bulbs last over twenty thousand hours, but they might lose their intensity over time. If you are a serious grower, you should replace HPS lamps for horticulture in the UK after every six thousand to ten thousand hours to maintain optimum yields throughout the year.
How do I know if my HPS bulb is completely used up?
An exhausted high-pressure sodium bulb typically repeats a cycle at the end of its life that is turning on, running for a while, turning off and then restarting after cooling down. The other signs for this include a blackened end of the lamp or a clearly visible reduction in brightness and spectral quality.
Are HPS lights expensive to run in the UK?
Yes, high-sodium lights are expensive to run in the UK as compared to LED lights. Roughly, a 600W system will cost 65 to 71 pounds per month in electricity due to high power draw and heat generation. Even though it will result in significant electricity costs, it may reduce the need for separate greenhouse heating.
Can I use HPS in a small, enclosed space?
Yes, you can use HPS lights in small and enclosed spaces, but it is generally not recommended without proper investment in cooling and ventilation to manage the heat generated by HPS. For small spaces, LED grow lights are a better option. If you choose to proceed with HPS light, go for a 150W to 250W model rather than higher wattages, and do not forget to maintain the proper ventilation. These models are easily available at a reputable horticulture centre in the UK.
Can I run HPS Lights at 240V?
Yes, most commercial HPS systems in the UK are 240V compliant. This is recommended to reduce amperage draw and run cooler compared to lower voltage options.
How many hours a day should I light my HPS lights?
HPS lights are usually run for 12 to 18 hours a day, depending on the plant growth stage. For the flowering or fruiting plants, it is recommended to turn on for 12 hours and turn off for another 12 hours. Additionally, the vegetative growth requires 16 to 18 hours of light daily to maximise yield.
How many watts do I require for my grow room?
To grow rooms, you would require 20 to 20 watts per square foot of space for a standard tent. You can also get Lumi Black Blade 100W, which is efficient for the grow room.
How long am I supposed to leave the lights on?
You can generally leave the lights on for 8 to 10 hours, but not more than 18 hours.
Why do I need LED lights for my grow room?
The LED lighting is important because they provide energy efficient, full-tailored spectrum light for photosynthesis while releasing minimal heat.
Are there specific types of LED lights that I need to use for my grow room?
When purchasing LED lighting, opt for grow lights that offer a tailored full spectrum and colours as well to promote plant growth.
What are the side effects of not having LED lights for my grow rooms?
The absence of LED lighting causes excess heat problems because traditional lights emit significant heat, higher energy costs because the traditional lights consume high amounts of electricity, and it also leads to increased risks of light burn.
How long do LED lights last?
LED lights last up to 17 years, which outlast HID and HPS.
What is the full spectrum of the LED grow lights?
The full spectrum provides complete wavelengths like the natural light, and it also includes blue, red, far-red and UV wavelengths. The full spectrum is ideal for the healthy growth of plants and better yields.
Are LED grow lights better than HPS?
Generally, LED lights are more efficient and effective compared to HPS in terms of energy, the cost of the LED lights and spectrum.
What are the factors to consider when buying LED grow lights?
When buying LED grow lights, consider buying lights with a full spectrum, lights that provide uniform coverage area, lights that provide passive cooling for heat management and lights that have dimmers and timers. You can opt for the Lumi Black Blade 100W that offers excellent functionality.
How can I select the right size of LED grow lights?
When selecting the right size of the LED lighting, calculate the size of the grow room and select an LED grow light that offers at least 30 to 50 watts per square foot for high-light plants and 15-20 watts low-light plants and ensure the footprints of the light match the area.
What is the electricity consumption of LED grow lights?
Generally, LED lights consume 100 to 300 watts for small to medium setups, and they can consume from 100 to 1000 watts for large commercial fixtures.
What is the best position for LED grow lights when installing?
When positioning the LED lights, ensure they are directly above the plants to achieve uniformity.
Can I use LED grow lights for all types of plants?
Yes, LED grow lights can be used for all plant types in grow rooms. They provide the full spectrum and controlled heat, which is ideal for the plants.
Are LED grow lights affordable?
The affordability of LED grow lights depends on the type of wattage, the brand and the spectral quality, but it can range from EUR 10 to over EUR 1000 for small spaces. The price range may start from EUR 10 to EUR 50.
