Based on a systematic review of the role of phytochromes in stress response and research progress in defense mechanisms in recent years, the improvement of crop resistance by utilizing light quality and genetic improvement of genes related to phytochrome signaling pathway in horticultural plant production was discussed. The importance of promoting increased crop yields and …

Principles of plant light quality photosynthesis and photomorphogenesis efficiency
There are two mechanisms by which light affects plant growth, development and yield and quality: one is to affect the photomorphogenesis of plants through photoreceptors; the other is to regulate plant photosynthesis through photosynthetic pigments, changing carbon and ammonia metabolism and photosynthetic products in plants. allocation. In addition to light intensity and photoperiod, light quality …

The regulation of UV on the growth and quality of facility plants
Due to the absorption of covering materials in greenhouses and greenhouses, the ultraviolet part of sunlight will be greatly reduced. An important feature of the greenhouse growth system is the lack of mid-wave ultraviolet UV-B (280~320nm) in natural sunlight. The physiological effects of this phenomenon are unclear. Plants often develop a thick leaf epidermis or …

Distribution characteristics of ultraviolet light in plant factories
The plant factory is a high-efficiency facility agriculture system that achieves annual continuous production of crops through high-precision environmental control in the facility. The computer automatically controls the temperature, humidity, light, CO2 concentration, and nutrient solution during the growth of crops. A brand-new production method that is not or seldom restricted by natural conditions. Plant …

Plant light quality biology-the basis of LED plant lighting theory
In the solar spectrum, the optical radiation in the 300-800mm band is called Physio-logically active radiation, and the 400-700mm optical radiation is called the Plant Photosynthetically Active Radiation (PAR). The former includes near-ultraviolet and far-red light, while infrared radiation is not physiologically effective radiation. 380～780nm is visible light, part of ultraviolet light and far-red light …

How many grams of weed can you get from an individual plant?（二）
SOIL AND NUTRIENTS PLAY IMPORTANT ROLES Cannabis plants have specific nutritional demands that must be met in order to push their yields to the limit. There are three nutrients in particular, known as macronutrients, that cannabis plants require above all else. These are nitrogen, phosphorous, and potassium. During the vegetative phase, when plants haven’t yet started to …

How many grams of weed can you get from an individual plant?（一）
Wondering how much weed you’d be able to grow from a single cannabis plant? Find out what to expect when growing your own. There’s no question that the goal of cultivating cannabis is to obtain the biggest yield possible. Whether you’re growing THC-rich buds to procure a stash that will get you stoned for months …

How much weed can you grow indoors on 1m²?
Roughly? Anywhere between 0 and 700g/m². Unfortunately, a more precise answer to this question isn’t that simple. The amount of cannabis you’re able to produce indoors depends on a wide variety of factors, including: *the genetics of your plants*the quality of your equipment*the nutrients and grow medium you choose to use*the actual space you plan to grow …
