Understand power (watt)
A watt is a measure of the energy input required for light. The output of the LED lamp depends not only on the function of the watt, but also on the quality of other components and designs. These components are:
LED chip quality
Lamp bead density
Optical design
The radiator
LED Driver Power Supply
The power increase reduces LED efficiency due to the temperature increase in the electronic circuit board. So when LED manufacturers claim that watts are a measure of a plant’s ability to grow, it’s questionable. Therefore, you need a lot of knowledge about wattage and PAR, and it must depend on the manufacturer’s information.
Manufacturers can position growth lamps higher above vegetation and illuminate large footprint areas. Then, if the LED emission is designed to be close to the plant, the output will be higher. The light intensity is lower at the edges.
The leaf tissue can touch the well-designed LEDs because they operate at a low enough temperature so that the tissue does not suffer any damage. So you can get these lights close to the plants. Light intensity is a limiting point, though, because too much burns plant tissue.
Diodes should have specifications to emit actual wavelengths. Well-known manufacturers use a complex process that means their diodes will emit the right wavelengths of light. Other manufacturers also produce inexpensive LEDs to appeal to budget-conscious shoppers.
Cheap LEDs may not emit the specific wavelengths needed by plants, and the intensity of light may vary. The customer should be aware of these facts.
LED lens
The quality of the LED depends on the lens to which it is connected. Optical lenses can affect size and output. If the required footprint and appropriate intensity are not provided, the health of the plant will not be up to scratch. That’s how you measure quality.
Adjust the height of the lights hanging over the plants.
Early stage of plant growth – place the lamp about 300mm above the plant. Therefore, it ensures a minimum internode length and provides internode space.
Nutritional period – now increases the distance between the light and the plant, possibly between 300-600 mm. Plants with lots of leaves need to lower the light so that it can reach the lower branches of the plant. Also, if your factory requires high lighting levels, keep LEDs above 300 mm; If we need a lower lighting level, keep the LEDs above 600 mm.
Change the way you water. If you are new to using LEDs, watering may cause some problems.
The watering guide is mainly based on HPS lighting. In the process, evaporation occurs. That’s why water is needed. However, when it comes to LED planting lights, watering or feeding is not an issue.
You will need to provide a 30% HPS light source for the plants. Add Cal-Mag when your plants are growing under LED lighting.
In hydroponic systems, evaporation is reduced, so you have to provide less nutrients.
In winter, you need to provide more heat in the room. This will promote the growth of the plant. The heat of the growing area is much lower than that of HPS illumination. Therefore, in winter, this may cause some problems, so if you use LED plant growth lights, you should pay attention to plants.
Set Light Cycle
The life cycle is crucial to the biological life of crops. Growers can manipulate it by increasing or decreasing the amount of light. Greenhouse growers can do this by using blackout curtains and extra lighting. During the growing phase of the plant, it takes about 18 hours of daylight a day. Nutritive crops receive 17 to 18 hours of light per day.
Light intensity
Adequate light levels for flowering are 400 and 700 uMoles/m-2s. Light should be evenly distributed across the tree canopy. Since the illumination of the LED plant growth lamp is directional, please pay attention to it. Light less than 10 inches may cause bleaching.
SOG and SCROG techniques will help create a corolla depth between 12 “and 16” and light will reach all locations. If any flowers fall below this level, prune them at the end of the second week. By the fourth week, remove all the large fan blades so that they can be photographed. Ensuring that the light path is consistent is critical.
The temperature
78F is the best appreciated temperature for any plant. Then the CO2 level should be 360 PPM. You should monitor the root zone temperature. Air temperatures above 85°F require cooler dark period air temperatures.
nutrients
As the temperature increased, the nutrient concentration in the dry area also increased. It can produce toxic levels in the root area. Therefore, reduce nutrient concentrations by 25-30%.
Often ask questions
Should you keep the lights on at all times?
It depends on the stage of growth. During the growing phase of the plant, 24-hour lighting does not cause any problems. But in the flowering or fruiting phase of a hydroponic tent FAQ, you need 12 hours of light.
Will regular LED lights produce the same results?
Yes, but it wasn’t a wise decision. After good soil, light quality will be the most important investment.
Can you invest in dimmers to adjust the spectrum?
For dimmable lights, there is no need to adjust the height, which is the main purpose of using it. The dimmer series includes vegetable dimmer and generous dimmer.
