Recently, the selection at Kweekverlichting.nl has expanded considerably. We often get asked: Which lamp should I choose? That's why we've put together a brief explanation of several types of lamps and their possible uses. We'll also address some frequently asked questions on this topic. Please note: these are general tips. Every grow is different, and of course, there are other important factors besides the lighting.
HPS grow lights
If your grow is purely focused on achieving a high yield, HPS lamps are still the best choice for flowering. However, their power consumption is often very high, which is why more and more growers are switching to LED. Furthermore, the duration of your grow is, of course, important. HPS grow lamps are often cheaper but don't last as long. Therefore, HPS is very interesting for short-term cultivation. For long-term cultivation, we recommend more energy-efficient lamps.
Why do I no longer need a reflector with HPS lamps?
It's usually recommended to use a reflector with HPS lamps. However, this isn't the case with Ecolum HPS lamps, which already have an internal reflector that ensures optimal light distribution.
Induction grow lights
Induction lamps are very interesting because they sit between HPS and LED grow lights in terms of power consumption and light output. The choice of the induction lamp's light temperature depends on the growing phase. For optimal efficiency, 6500K induction lamps are used during growth and warm white 2100K lamps for flowering.
Be sure to use a reflector with induction lamps!
With induction lamps, it is best to use a reflector for optimal effect.
LED grow lights
The most efficient lights are no longer just HPS lamps. The latest generation of LED grow lights is not only more energy-efficient but also offers high light output thanks to the use of powerful 3W LEDs. However, the prices of LED grow lights are considerably higher. Therefore, these lights are especially interesting if you grow frequently or have plants that take a long time to mature.
How many watts of LED do I need to replace a 400W HPS?
For this, we recommend a 250W Spectrabox. A 200W Spectrabox will also work, but the yield will obviously be slightly lower. LED UFO lights and grow spots are primarily suitable for growing a few plants in a small grow tent.
Is LED also good for flowering or only for growth?
In recent years, LED grow lights have also been available that are beneficial for flowering plants. This used to be a problem, which led to some skepticism among growers. However, the older grow lights didn't adequately utilize the various light colors required for flowering. The Spectrabox Gold, for example, has eight light colors and can be specifically adjusted for the flowering phase. Very good flowering results have been achieved with it.
How do I get more out of my investment?
If you have a long-term project, you can easily recoup your investment in LED grow lights. The biggest savings, of course, come from the lower power consumption. The lifespan is also crucial. LED grow lights last up to seven times longer than HPS. Furthermore, the lights generate less heat, saving you money on your exhaust system. LED lights also don't have peak voltage, eliminating the need for a meter panel with relays.
