More and more people are trying to grow their own cannabis. However, marijuana is a light-loving plant, and many places don't have enough light conditions. At the same time, regulations often stipulate that growers must "hide" the cultivation site of marijuana.
Therefore, artificial light is indispensable, and LEDs are becoming more and more mainstream because of their advantages of perfect spectrum, and low temperature.
Here are 3 points you have to know about using Led Grow Lights to grow cannabis, you would understand the advantages of Led Grow Light better as well.
1/ When your plants are in the seedling stage after germination, you need to turn on your Grow Lights. Note that the light in the seedling stage cannot be too strong or too weak, so you need to adjust the intensity of growth. There are generally two ways: one is to adjust the distance between the light and the plant, and the other is through the control system on the light (if your Plant Light has one).
Another important point is that the daily light integral (DLI), DLI is related to the daily light time/photoperiod and the light intensity of the lamps. For details, please refer to our article (https://www.ultraplantled.com/news/how-to-decide-the-lighting-distance-of-your-led-grow-light-78726.html); generally, 18 hours per day for Lighting and 6 hours of darkness for this stage.
2/ After the seedling stage, the plants enter the vegetation stage. At this time, pay attention to increasing the DLI, and the photoperiod is generally set to 18 hours of light and 6 hours of darkness.
Another important point is that when you increase the DLI, you should pay attention to the coordination of the growth environment, such as the increase of carbon dioxide concentration and sufficient nutrients to ensure that the plants can fully utilize the power of light.
3/ When the plant grows to a certain height, you can induce flowering by changing the photoperiod, which is imitating the seasonal changes in nature.
The flowering period is generally set with a photoperiod of 12 hours/12 hours. The point is to maintain absolute darkness during the dark period. Once the dark period is interrupted by light, one cannot expect satisfactory results.
In fact, experienced growers deliberately switch to lights with a greater proportion of red light during flowering to boost yields.
To sum up, to grow good cannabis flowers, growers need to switch the lights on and off every day to control the photoperiod, and adjust the light intensity at different stages. Experienced growers also use lamps with different spectrums depending on the growth stage. According to research, even the optimal light strategies for different cannabis varieties are different.
As a result, it is a complex and repetitive process that requires a considerable investment of time and effort from the grower. But there is a way to reduce the operation cost of the grower and the risk of making mistakes in planting.
It's to set it up and hand it over to the robot to execute it perfectly. Smart lights like Ultra Plant™, have the ability to adjust and automate spectrum, intensity and runtime change. Makes planting easier and more harvestable at the same time.
