There are three major light source technologies: incandescence (incandescent lamp), an electrical discharge (fluorescent, HID), and solid-state light sources (LED, OLED). The first and two are known as “legacy” technologies, and the third is considered as modern technologies. In order to choose the best light source for plant growth, it is necessary to understand the […]

Light is the basic environmental factor for plant growth and development. It is not only the basic energy source of photosynthesis but also an important regulator of plant growth and development. The growth and development of plants are not only restricted by the amount of light or light intensity (photon flux density, PFD) but also […]

The HPS lights, high sodium pressure, have been the most used until today in the cultivation of indoor cannabis. However, with the cost of LED going down and technology of LED improving, growers are growing more with the new LED lights and therefore the LED horticultural lighting industry is expanding rapidly. In this article we want to put […]

Creating an ideal environment for cannabis plants is only feasible if we understand the principles of nature – we cannot ignore the light spectrum. Most cannabis growers have several goals in mind when planning an indoor crop. Achieve higher yields, increase THC level, or simply improve plant health. This strategic planning implies having knowledge in various scientific […]

How is light measured in horticulture? To choose your horticultural lighting, it is essential to understand and know the metrics of the field. These will be useful to you in achieving your production and growth objectives. You will cross paths with certain measures such as: Watt, Lumens, LUX, PAR, PPF and PPFD. Indeed, they are related to lighting, […]

Lettuce is an excellent crop for greenhouse production throughout the year, especially in colder areas in the north. Lettuce is a crop with low light and low temperature, so additional lighting and heating costs can be minimized. On the other hand, local producers who can provide a constant supply of fresh and gourmet-quality lettuce can often charge […]

Light quality has a great impact on plant growth and development, photosynthetic characteristics, yield and quality. Studies have shown that green light and red light significantly promote the elongation of colored sweet pepper seedling stems, blue light has a dwarfing effect on seedlings, and composite light has a better effect than monochromatic light, and is […]

Light quality can affect many physiological processes of plants, especially in terms of photosynthesis and plant morphogenesis. The rational use of specific light waves is beneficial to improving the nutritional quality of vegetables. It is generally believed that red light is beneficial to the accumulation of carbohydrates and can promote the synthesis of soluble sugars, […]

Light is one of the most important conditions in tissue culture, mainly in terms of light intensity, light quality, and light period: Light intensity Light intensity has an important influence on the proliferation of cells and differentiation of organs. From the current research situation, light intensity has a significant effect on the initial division of […]

With the rise of cannabis cultivation, and after receiving so many questions from many people who begin to grow cannabis indoors do not get expected results, we felt obliged to make several general recommendations to new growers from our experience of growing with some prominent commercial growers. Following these tips, you will achieve a quality harvest without unforeseen events.  Always remember safety […]
