Mounting Tips: The right light

For the cultivation of a hemp plant indoors, appropriate artificial light is a prerequisite. Even if the plant is standing at the window, it does not get enough light to grow big and bushy on the one hand, but on the other hand not to come into the flowering phase. The background to this is that hemp plants in the wild with their one-year life cycle grow through the summer and start flowering at the onset of autumn - i.e. when daylight is fading - so that they can reproduce in time before "their time runs out". By artificially illuminating the plant further, it is almost like a perpetual summer, and it continues to invest energy in its growth. The brightness and color temperature of the lamp are the most important factors in determining the correct cannabis lighting, but considering your own electricity bill, you should also keep an eye on the power of the lamp - after all, your cuttings should be kept under light for at least 18 hours a day!

COLOR TEMPERATURE

Hemp plants love sunshine - therefore the right color temperature for your hemp lamp is as similar as possible to daylight. You can achieve this by choosing rather cool, bluish light with a high Kelvin number (4,000 to 7,000 Kelvin), for example fluorescent tubes, LEDs in neutral white to daylight white, or metal halogen lamps. The unit lumen provides information about the luminosity of a lamp. Lumen actually refers to the luminous flux, i.e. the intensity of the perceived light. In times of energy saving lamps this unit is preferred to indicate the brightness, since an energy saving lamp should not give less light despite lower consumption.

Guide value for the selection:

60-watt light bulb: 600 lumens; 20-watt energy-saving lamp (A): 1,150 lumens; 40-watt fluorescent tube: 2,300 lumens. For cannabis cultivation, about 25,000 lumens per m2 are recommended. For legal cannabis cultivation, this is the correct lighting level throughout, as it supports the plant in its growth but not in flowering. Assuming that ten cuttings per square meter can comfortably accommodate ten cuttings, about 2,500 lumens should be sufficient to illuminate a single cutting properly. You can easily extrapolate this, depending on how many plants you place next to each other. The number of watts is rather secondary because, as mentioned before, the lumen value is decisive for the brightness of your hemp lamp. Of course, you can save the climate and your wallet by using energy saving lamps - considering how long your plant should get light for, this is very important.
illuminate correctly

Our lamps tip

We recommend one energy-saving LED lamp with about 2,500 lumens luminous flux and a color temperature of 5,000 Kelvin or higher per cutting. Metal halogen lamps, for example, are well suited for this purpose. Many hobby gardeners and breeders of exotic plant varieties like to use these lamps to provide their plants with sufficient "daylight" even in the winter months. Important: For this type of lamp you always need a ballast, which regulates the energy discharge! Who would like to have it a little more simply and without excursion into the specialized trade, can seize to usual energy energy energy-savings lamp. If you illuminate your cutting with two 20W energy saving lamps of efficiency class A and maybe use a reflector in addition, your hemp plant is well supplied. The best thing to do is also here: observe how it is doing! If the leaves simply don't want to get bigger and denser, and everything is right with the soil and roots, then it probably needs more light.
