Installation requirements for LED grow lights
300wLED grow light installation requirements
1. Illumination distance
The light distance of the 300wLED grow light is very important. You have to adjust the cannabis at different stages, and the distance should be unified to make the light even more uniform. If the distance is not well controlled, it may harm the growth of cannabis. The general recommendation is that the germination stage distance: 60 cm, the seedling stage distance: 75 cm, the growth stage distance: 45 cm, and the flowering stage distance: 30 cm.
2. Evenly distributed installation
Measure the floor area. Multiply the length by the width to get the square meters of the cannabis planting area. You can make the right choice based on how much power to provide per square meter, that is, how many 300w LED grow lights are installed per square meter. In this way, each lamp can be evenly distributed, so that the outer edge will receive strong light, so that the light will be more uniform, and the growth of plants will be more effective.
3. Photoperiod operation
Like many plants, hemp matures with the change of seasons. When the photoperiod is shortened and the light wave is extended, the cannabis plant is prompted to produce flowers or seeds to prepare for the next generation of plants. When growing hemp indoors, growers use 300wLED grow lights to control the photoperiod of plants to achieve better planting results. Although the seedlings grow well under constant light, the vegetative plants should maintain a light cycle of no less than 18 hours. Although some growers expose their vegetative plants to constant light, it is believed that the healthiest and richest plants will experience at least a few hours of darkness in a 24-hour period. Sending a flowering signal to a cannabis plant requires the light cycle to change to 12 hours of light and 12 hours of darkness—no more, no less.
High-quality cannabis planting genes
Good genetics is essential to achieving a bumper harvest. Good genetics can not only produce high-quality cannabis, but also adapt to your level of knowledge as a grower. There are currently many seed banks offering a wide range of conventional seeds, self-flowering seeds and female seeds.
Remember: only female plants produce buds. You can ensure that you have female plants by using feminized seeds.
For indoor novice growers, we recommend first-generation hybrids, which tend to reduce pests and nutritional problems.
Indica hybrids. For example, the easiest cannabis planting variety to grow indoors is Critical Bilbo, which can be grown with only 50 to 12 hours of sunshine per day. Another variety suitable for the first crop is the White Widow. Although it takes 60 days to bloom, it is resistant to most pests.
Several hemp varieties like OG Grape and KryptandReCon of DNA Genetics are good. Their taste is very strong, with a sour taste, and sometimes reminds us of turpentine. Usually the products they provide are medium.
The right amount of watering
Watering in cannabis cultivation is one of the most common operations in indoor and outdoor cultivation. Before you start planting, you should know the amount of water available. In some areas, tap water is not suitable for the proper growth of cannabis. In this case, you can use bottled water or reverse osmosis equipment. Note that there are many variables that make us water more or less frequently:
Large plants need more water than small plants.
Low relative humidity causes plants to require more water.
More heat means more water demand.
Flowering plants need more water than growing plants.
Large potted plants require longer drying time than small potted plants.
The frequency of flood irrigation is lower than normal irrigation.
Generally speaking, hemp is grown indoors. If we water it manually, we water it every two or three days. If it is an automatic irrigation system with an irrigation pump and dripper, it is usually watered several times a day, but the amount of water is very small.
As a rough idea, we can use about 10 or 15 liters of water to pour a square meter of indoor space. It will be different according to what we have said before: plant size, stage, relative humidity, temperature, etc. We recommend that the amount of watering be 10% to 20% of the substrate water volume: in a 5-liter pot indoors, it can be used at most Water one plant with half or one liter of water.
Substrate fertilization
There are several mainstream substrates for growing hemp, including a wide selection of media as peat-based substrates and black or inert substrates for hydroponics, such as coconut, wool rock, etc. Each substrate has different characteristics, and growers should always choose the substrate most suitable for their cultivation. For example, there are substrates with added fertilizers and perlite, which can fully oxidize the root system, and currently has achieved great success in indoor cannabis cultivation. Solid modifiers such as worm humus or bird droppings are additives to improve the physical and chemical properties of the soil, because they contain nutrients and organic matter, creating suitable nutrients for the growth of hemp plants.
In any case, if you are not prepared to have a thorough understanding of various substrates, you can start using organic soil for planting, because it will also bring you better results.
It is best for novice growers to start with organic fertilizer. Natural organic hemp fertilizer made with nutrients comes from biological materials such as algae or natural plant extracts, and does not contain chemical ingredients. It is the best choice for most gourmets. They are specially designed fertilizers for organic soil substrates or growers who prefer good-quality, over-yielding crops. Bud 100% organic has more flavor and aroma than other fertilizers. Organic fertilizer contains carbon particles. When it comes into contact with the soil, the fungi in the soil release carbon particles to provide nutrients for plants.
Correct harvest time
The harvest of cannabis cannot depend on luck. There is a time frame, not too long, we can harvest our plants. You need a microscope to actually observe the trichomes. A handheld microscope ranging from 30x-100x can clearly see the color of the trichomes. At this stage, the trichomes change from transparent to opaque white, and from transparent to opaque, which indicates full maturity. The trichomes no longer produce additional THC. Not all trichomes develop at the same rate, and before you see uniform opaque trichomes, you will start to see some amber trichomes. Once the amber trichomes appear, THC decomposes due to exposure to oxygen and ultraviolet rays. At this time you can assume that you have reached the maximum THC and your plants are safe to harvest.
Although the 300wLED grow light has a good effect on cannabis supplement light, it should be noted that hemp is not only needed to supplement light, but also from many aspects such as seeds, water supplement, fertilization, etc. This is a skill, and then it is matched with 300wLED The effect of the plant light will give better growth of cannabis.
