We want to plant cannabis indoors first, taking into account the lighting system, ventilation system, temperature and humidity in the growing tent, how to fertilize the cannabis, how to give marijuana quarantine and other factors, we will mainly talk about how to choose lighting System and use.
These lamps should be 50/60 cm (600 watts sodium), 35/40 cm away, and 400 watts of sodium lamps, which should rise with the growth of the plants, always at the same distance from their tops.During growth, cannabis plants require 18 hours of light and 6 hours of darkness for rapid and healthy development. This stage should last for a minimum of two weeks or until the plant is about 25 cm high.During flowering, cannabis plants require 12 hours of light and 12 hours of darkness (the plant is completely dark is very important). The length of the flowering period varies from plant to plant and depends on the phenotype, which ranges from 50 to 70 days. Typically, growers use HPS lamps, LED panels or LEC CMH lighting kits at this stage.
LED plant growth light
LEDs are the most energy efficient type of growing light. This means they provide the most light compared to operating costs. Another advantage of LED lights is that they run cooler than HID lighting – no heat at all. In turn, this means that the risk of "burning" the plant from too much heat is small, which helps keep the temperature inside the growing chamber down. LEDs also don't require ballasts to work like HIDs, you can simply plug them into a standard socket.
The initial cost of an LED growth lamp can be high compared to other types of illumination. High-end LED luminaires with modern LED modules can easily bring you thousands of euros in return. On the other hand, if you plan to grow a lot, LEDs run cheaper, and lower temperatures can have an impact on your initial investment.
It is worth noting that unlike HID and CFL lamps, there is no industry standardization. As a result, the current LED growth market is flooded with retailers who are trying to sell poorly designed LED lights by making poorly designed and false claims. In terms of LEDs, you get the price you need and it's worth paying extra for your research and for famous brands.
