There are two chemical reactions in the leaves of grows
1 Light response
2 Dark reaction
Photoreaction is the synthesis of light energy to synthesize carbon dioxide from water into starch, which can only be carried out under light conditions, and the dark reaction is respiration. By decomposing starch to obtain energy for the growth and development of grows, we can verify:
1 The leaves without dark treatment are boiled in alcohol for 10 minutes, the purpose is to dissolve the pigments of the leaves, and then put the leaves in iodine water, the leaves turn blue, which proves the presence of starch in the leaves
2 The leaf treatment method after 24 hours of case treatment is the same as above. The leaf does not turn blue, which proves that the starch has been consumed and the nutrient in the leaf is starch.
As long as there is light, photosynthesis can continue to promote the accumulation of organic matter and make grows grow. However, the light time required for each stage of grow growth is different. Many grows are subject to the length of light to regulate their flowering. It is difficult for them to bloom under constant light, which will bring negative effects.
Features of LED grow light:
(1) Imported chips, basically no problems in performance;
(2) High luminous efficiency, 90% of the light emitted by LED grow lights can be absorbed by grows;
(3) High-quality products and perfect after-sales service;
(4) Integrating dust-proof, anti-corrosion, and thermal shock resistance design into one, it can meet the requirements of harsh outdoor applications;
(5) Optimized design of light and color to provide you with a comfortable lighting environment;
(6) Long life span of 50,000 hours and 5-year warranty, so that customers can rest assured;
(7) Full-spectrum LED grow lights to meet the spectrum required by grows.
LED grow light lighting suitable time
1. The degree of light joy of grows is determined
Not to mention that LED grow lights do not rest, almost all living things need to rest, so it is impossible to use LED grow lights to fill the grows with light, which will have a bad effect on the grows. Studies and experiments have proved that the best time for grows to add light is controlled at about 12 hours, and it is necessary to leave enough time for grows to rest for 4-6 hours.
For light-loving grows, it is necessary to use LED growth lights to supplement light for grows at 6:00-10:00 and 17:00-00:00, because 10:00--17:00 is the sunlight that meets their growth needs Time period, so it takes about 11 hours for grows to fill in light.
For grows that do not like light, their growth needs can be met when there is sunlight. The time for supplementing light with LED grow lights only needs to be set according to the local sunrise and sunset time, and the supplementary light time should avoid grow rest time as much as possible.
2. Environmental decision
The growing environment mentioned here includes the difference between the north and the south, the difference between spring, summer, autumn and winter, and the difference between indoor and outdoor sunlight. Regional and seasonal differences can be set according to the light law, the closer to the equator, the stronger it is to set the lighting time with LED grow lights. Strong in summer and weak in winter, set the lighting time with LED grow lights according to local conditions. There is a big difference in the light that can be received for indoor and outdoor growing. It takes 16-18 hours to fill up the light with LED grow lights for the whole time. Outdoor grows use LED grow lights to fill up the light according to the difference in the illuminance of sunlight.
No matter what grow you grow, you must first understand the light required for growing, and then use LED grow lights to supplement and dim light according to the growing environment to give grows better light and growth status.
