Our COB LED lamps are equipped with a separate farred dimmer or switch. This ensures that the user can control the vegetative phase of the plant.
In the vegetative phase this unique color can be dimmed separately. Once switched to the duration of hours needed for the flowering period, it can be switched on to simulate flower formation
This unique color provides the right temperature for nutrient uptake and because it is dimmable, the user can determine the evaporation of the plant. In the final phase this color can be dimmed again so that the flowers remain compact because they do not open due heat transpiration.
In order to achieve the best results. We advise to check our VPD information.
The dimmer is located on the right with steps of each 10%. The lowest value is 10%
Far-Red Light and Vegetative Growth
R:FR affects plant growth. A large amount of far red light causes the stem to elongate/lengthen and the leaves to grow longer and wider. This is because plants try to stretch their bodies to get more sunshine. Therefore, a plant can look “elongated” and these slender stems are sometimes too weak to hold thick cannabis. A large amount of far red light can also reduce the levels of chlorophyll, anthocyanins and antioxidants in plants. Chlorophyll and anthocyanins are pigments that make plants rich and colorful, which can take into account the novelty and value of harvest. Antioxidants prevent harmful free radicals – whether they are plant or human – ideally, plants that growers want bright colors and high levels of antioxidants. In order to produce plants with strong stems and bright colors, they should be given a lot of red light and a small amount of far red light. This is especially the case if the plants are grown under high density conditions.
Far-Red and flowering
At this point, you may begin to notice a trend: plants associate far red light with shadows. Therefore, if you give plants too much red light, they will think they are in a cool environment. Excessive shading can put stress on plants, so precautions need to be taken to avoid these situations. The seeds will avoid germination and the stems will stick out to reach more light. In order to cope with excessive shade, plants tend to bloom. Flowers are the reproductive tissues of plants. If plants believe that there is a danger of death (from too many shadows), it will begin to multiply as soon as possible so that it can pass its genes to future generations. A lot of far red light has accelerated the blossoming of many species – tomatoes, potatoes, cucumbers, beans, wheat, mustard and many ornamental flowers. In some species, far red light also increases flower yield.
As growers, we can use this knowledge to make a profit for ourselves. If we want a plant to start to bloom (such as a stubborn cannabis plant that refuses to germinate), we can give it a lot of far red light. Far red light should be applied for a short time to induce flowering and stop, once the buds begin to appear. Applying a small amount of far red light at night (~ 2μmol-1 m-2) can also effectively accelerate flowering and increase the number of flowers
