How to build your own led grow lights


You are at the right page if you are looking for info on how to build your own led grow lights. This article looks at the construction of an optimal grow light for a small space. Before you start making the led grow lights, it is essential to understand why growers use both metal halide (MH) and high-pressure sodium (HPS) for plant growth and flowering. In simplified words, there is blue for veg and red for the flower. MH is needed because of the inadequate blue in HPS bulbs and plants need blue light to grow. This is known as phototropism, and if there is not enough light in the blue spectrum, the plants keep searching for it.

The plants need the spectrum they respond best to. The Red chlorophyll A & B receptors offer a higher response as compared to the blue chlorophyll A & B receptors. During the mid-flowering stage, the upward growth slows down, and the blue light is not as that important to marijuana growth at that point. The plants make use of entire visible light spectrum at different efficiencies and can adjust to imperfect balance light conditions. Bi-color LEDs focus on the red and blue chlorophyll A receptors. The essential information here is that plants can be grown based on

two narrow spectral bands.

When working with commercial LEDs, there is an issue of unregulated current that can burn the bulbs. Another issue is the laser-like focus of the narrow-angle LEDs, and that could lead to lighting or spotting if too close to the plant. Even with both color LEDs, the issue of color mixing remains. Another major consideration is that while lumens per Watt when you focus on how to build your own led grow lights. The LEDs carry distinct advantages as they have wider viewing angles and longer life.

Moving further with how to build your own led grow lights, it is essential to know that Spectrum can be custom designed. As Lumen decay is slower in LEDs, they are likely to hold on to their brightness throughout their life. Moreover, HIDs carry metal filaments that get very hot. What LEDs are weak is in the area of color mixing and the lower luminous efficacy could not compare to HID.

Before you proceed with how to build your own led grow lights, it is helpful to study the sun and the photosynthetic response curve to get the best possible grow lamp. In the experiment, the maximum amount of heat dissipation is at about 165 Watts. Five emitters at about 28 Watts each is selected as well as four 2700K and one 5000K. Active cooling with the help of fans can reduce the size of the heat. Five monster heat sinks at 50 Watts of heat dissipation are attached to an open air aluminum frame for higher cooling capacity. LED holders are screwed into the heat sink. Five separate constant current LED drivers are used for providing a constant current. Superior commercial LED grows lights are used to prevent current fluctuations.

Those who are not looking for an elaborate process for how to build your own led grow lights can use just one 5000K emitter, heat sink and driver. Go for a simple setups and this is just ideal for a small dish of seedlings for 2-3 weeks of vegging. Spread out the light sources to provide much better lighting than a single source.
