The most challenging step is arguably choosing to clone the mother. It is the cornerstone of the whole process, so don't worry, choose the first healthy plant you see!
Analyze your plants and choose a plant that is tough, fast-growing, high-yielding, healthy buds, and large roots.
Before making the first cut, make sure your plants are in a vegetative state. Although you can plant the plant while it is flowering, it is difficult to take root. This increases the mortality rate. If you are trying to clone a game for the first time, you may not have enough knowledge or rich growth experience to decide your best choice.
In this case, just choose a female in a vegetative state, and it looks healthy. We also recommend cloning plants from ordinary seeds instead of using feminized seeds. Remember, cannabis plants produce feminized seeds only when they are stressed. If you pick plants from these seeds and stress them again, they may become hermaphrodite.

The plants you choose must be at least two months old. Your best chance of success is to choose a plant that has been in a vegetative state for three months. By exercising this degree of patience, you can obtain multiple clones from a single plant. Make sure that the plants you choose absorb about 10% less nitrogen than usual in the two weeks before pruning. This strategy increases the chances of successfully taking root.

When using greenhouse equipment to grow cannabis, china blackout greenhouse factory usually have a supplementary light system to supplement the lack of sunlight.
In order to avoid light pollution, we use greenhouse light deprivation systems, which is used when the fill light is turned on.

Of course, we will also make heating, cooling, CO2 and other equipment in marijuana blackout greenhouse to create a climate suitable for cannabis cultivation.

Hydroponic vegetables

refer to vegetables that are cultivated under the traditional soil cultivation form, in which most of the roots grow in the nutrient liquid layer and only provide water, nutrient and oxygen through the nutrient liquid. Hydroponic leaf vegetables have the characteristics of short growth cycle, clean product, good taste and good benefit. The varieties of hydroponic vegetables are mainly leaf vegetables, such as lettuce, green vegetables, cabbage, water cabbage, amaranth, chicory and so on. Preparation of nutrient solution is the key technology for normal growth of hydroponic vegetables.

At present, the nutrient solution formula used in the production of leafy vegetables is 1122g calcium nitrate, 910g potassium nitrate, 272g potassium dihydrogen phosphate, 40g ammonium nitrate, 247g magnesium sulfate, 1.2g boron sulfate, 0.09g zinc sulfate, 4.2g iron chelate, 27.8g ferrous sulfate and 37.3g disodium ethylenediamine tetraacetic acid per 1t nutrient solution. Leaf vegetables are grown on substrate. Vegetable seedlings grow to the colonization stage, seedlings from the soil or soilless cultivation matrix, can be directly planted in the pipeline equipped with funnel filter, or through root treatment and then planted in the pipeline water, the specific treatment method:

1. Wash soil or other cultivated substrate with clean water to remove roots;
   
2. Cut off old or dead roots, dead skin and excess lateral roots;
   

   3. Soak roots with hydroponic plant disinfectant for 15-20 minutes to sterilize and disinfect. 4. Rinse with water again several times before colonizing.

   

   The production management
   

   1.Temperature control Hydroponics leaf vegetable root growth environment is nutrient solution, the temperature of nutrient solution directly affects the speed of leaf vegetable growth, the appropriate nutrient solution water temperature is 15-18 ℃, the temperature is 18-23 ℃. In summer, with high temperature and strong light, leafy vegetables grow fast, have low nutrient content and poor quality. Moreover, the stems and leaves of leafy vegetables contain more moisture and are crisp and tender. Strong light or water vapor condensation droplets are easy to burn the leaves, causing spots on the leaves and reducing the commercialization. Therefore, in the production, fan wet curtain cooling system and shading net are used to achieve the purpose of ventilation and cooling, control the growth of leafy vegetables and ensure the quality. However, it should be noted that the indoor light time and intensity must meet the requirements of the growth of leafy vegetables. In the morning and evening, the shade net should be pulled up to increase the weak light time to increase the color depth and thickness of the leaves. In winter, the temperature of the nutrient solution is preheated to reach the temperature required for the growth of leafy vegetables.

   
   

   2.Concentration regulation winter temperature is low, the growth of leafy vegetables is slow, in order to improve the growth rate, the concentration of nutrient solution can be appropriately high, but not too much nitrogen, so as not to cause the taste of leafy vegetables, reduce the quality. Leafy vegetables grow faster in summer, and nutrient solution concentration is slightly lower than that in winter. The growth rate of leafy vegetables can be controlled by increasing the number of cycles to improve their quality.

   

   
   

   3.Timely liquid supply The time and times of nutrient solution supply mainly depend on the cultivation form, vegetable growth state and environmental conditions. In the cultivation process should be timely liquid supply to ensure adequate nutrient supply. The time of liquid supply is generally chosen in the daytime, and no or little liquid supply at night. The number of liquid supply in sunny days is more, and the number of liquid supply in rainy days is less. More when the temperature is high and the light is strong, less vice versa. Under normal circumstances, 2-4 times a day, each time hold in 30 minutes.
   
   

3. Replacement of nutrient solution The nutrient solution should be replaced timely after a period of use. Because nutrient solution in the process of use will gradually accumulate too much material hindering plant growth, nutrient imbalance, a large number of bacteria, resulting in root growth arrest, and even lead to plant death. To grow the vegetable with shorter cycle commonly, each crop changes nutrient fluid. At the same time, NFT Gutters and plastic pipes should be cleaned and disinfected once a year.
   
   
   

As the optimum temperature for most crops is usually below 30 degrees, the internal temperature of agricultural plastic  greenhouse for tropical crops should not exceed 35 degrees, and that for hardy or shade-loving crops should not exceed 25 degrees.  But for most of the country's low sea wave areas after May the temperature will be more than thirty degrees, intelligent greenhouse greenhouse without the use of shading and cooling equipment, the temperature will be as high as forty or fifty degrees, not suitable for the growth of any crops.  Today, I would like to share with you some of the installation points of the most important cooling system in summer: fan water curtain.  

First, temperature gradient design  
The temperature gradient difference between the fan and the water curtain should not be more than four degrees.  This needs to design fan water curtain exhaust distance should not exceed 48 meters.  Because the exhaust effect beyond the exhaust distance of the fan is reduced, the temperature of the air inlet of the water curtain is low, and the temperature of the air outlet at the fan location is high.  
Two, Cooling Pad &Fan System principle  
1. The fan starts to pump air outward to produce negative pressure outdoor air through the water film of the water curtain to evaporate and absorb heat to cool down.  So there are two main functions the first is the ventilation function, the second is the evaporative cooling function.  

2. The cooling principle is that humidity increases and the temperature decreases.  Therefore, the cooling effect is good in north China, and the effect is worse in high humidity areas.  

Three, Cooling Pad &Fan System layout need reference data  
1, the number of fans, which is related to the intelligent greenhouse internal ventilation volume.  
2. The area and height of the water curtain are related to the heat absorption effect of evaporation.  
3, the water volume and head of the pump.  The length of water curtain for a normal pump should not exceed 40 meters.  
4. The size of the reservoir is related to the water supply. 

Rainwater will cause certain harm to the greenhouse, so it is necessary for us to do a good job of rain proofing the greenhouse. Growing vegetables in a greenhouse is a popular way at the moment. There are many types of greenhouses, large or small. Remind everyone to do this in terms of rain protection.

First of all, the top vent of the greenhouse is rainproof. During the construction of the greenhouse, the position of the air outlet is located on the top of the greenhouse. Do not allow rainwater to pour over the top due to drainage and cause damage.

There is a waterproof membrane on the top. Prepare a plastic film with good light transmittance, the length is determined according to the greenhouse, and the width is determined according to the size of the tuyere. The upper end is fixed under the greenhouse, the two ends are fixed with iron wires, the middle can be fixed with a rope, and the lower end is fixed on the column under the tuyere, so that the rainwater will flow down and flow into the canal.

Due to the high humidity after rain, in order to prevent the infection and spread of germs, it is necessary to promptly clean up the residual branches, fallen leaves, and the diseased plants in the field, and clean up the old leaves, yellow leaves and diseased leaves at the lower part of the plants, and concentrate the treatment to reduce the germs. When conditions permit, the greenhouse shall increase the ventilation and humidity. Wind and rainy weather will cause a lot of sludge to splash on vegetable leaves. It can be combined with spraying foliar fertilizer or spraying to clean the sludge on the back of the leaves to enhance the effect of light and quickly restore growth. After the heavy rain, soil compaction occurs in the field. It is necessary to wait for the rain to stop and the sky should be fine, and seize the time to carry out cultivating and loosening the soil to improve the physical and chemical properties of the soil and increase the vitality of the root system.

In agriculture, 8mm hollow transparent color is generally used as a covering material. It has good thermal insulation coefficient, light weight and high structural strength. It is favored by multi-span greenhouses in cold areas. But what I am sharing with you today is a case of using milky white sunlight panels in a corrugated greenhouse.


First, the use of PC greenhouses

Greenhouses are used as vegetable storage and sorting centers, cold storages, offices and other functions. However, since it is not suitable to build concrete buildings in the agricultural park, the design of the corrugated Polycarbonate Greenhouse with the top and the surrounding milky white material covering is used.


2. Polycarbonate Greenhouse model

1. The specifications and models of the steel skeleton of the solar panel greenhouse are 150*150*3.75*4500mm for the columns, 50*70*2.5mm for the truss beams, 50*100*2.5mm for the longitudinal truss beams, 375*2.2*4000mm for the water tank, and 375*2.2*4000mm for the greenhouse. The surrounding beam is 50*50*2.0,. The span of the greenhouse is 10.8 meters, and the bay is 8 meters. The greenhouse is 5 spans, 54 meters from east to west, 5 bays and 40 meters from north to south, and the building area of the greenhouse is 2160 square meters.


2. Greenhouse covering materials

The top and all sides of the greenhouse are covered with 10mm milky white sunlight panels, and the light transmittance of the sunlight panels is 10%. This can not only ensure the thermal insulation of the greenhouse and the use of normal greenhouse installation profiles, but also ensure that the interior of the greenhouse will not be too high to affect the temperature in the shed.


3. Advantages of milky white sunlight panel sorting center

1. It meets the functions of the park, builds speed blocks, is convenient for construction, and has low requirements for the bearing capacity of the foundation. Normally, it can be installed in 45-50 days.
2. Hot-dip galvanized light steel structure, the cost is more economical and practical, and the service life is more than fifteen years.

3. Non-large span design, strong wind and snow resistance. At the same time, the interior is bright and meets normal working conditions.

How much do you know about the intelligent greenhouse control system? Everyone who builds a greenhouse knows that when planting in a greenhouse, attention should be paid not only to irrigation and fertilization, but also to the temperature, humidity, and light in the shed, as well as to understand the indoor environment and to ventilate regularly. Therefore, a lot of manpower is required for actual planting in the greenhouse.

  The intelligent control system is a product specially designed for greenhouses. The greenhouse can realize functions such as automatic irrigation and fertilization, automatic constant temperature and humidity, and automatic ventilation. Through automatic control, manpower can be saved. So how does the intelligent greenhouse control system realize automatic control? What is the specific principle? Let me introduce to you.
   Regarding the principle of the greenhouse control system, we can give a few examples, such as the automatic control of the greenhouse. The system can monitor the temperature information of the greenhouse in real time through the room temperature sensor. When the temperature of the greenhouse is lower than the standard value, the system will automatically start the constant temperature system to adjust the temperature information of the greenhouse. When the room temperature reaches the standard value, the system will automatically close the constant temperature system.

In addition to controlling the smart greenhouse, there are also irrigation, fertilization, and ventilation. They are all the same principle. Soil moisture sensors monitor soil moisture information to realize automatic irrigation; use soil sensors to monitor soil nutrient information to realize automatic fertilization; use greenhouse carbon dioxide sensors to monitor greenhouse air quality and control automatic ventilation.

The above mainly introduces the control principle of the intelligent greenhouse, which is mainly used in the fields of automatic control of the agricultural greenhouse environment, high-tech agricultural demonstration projects, and agricultural scientific research and teaching.

The ebb and flow method, also known as flood and drain, is a hydroponic growing technique used to cultivate plants without soil. In this method, plants are placed in containers or trays filled with a growing medium, such as expanded clay pellets or rockwool. The containers are periodically flooded with a nutrient-rich solution and then drained.

Here's a step-by-step breakdown of the ebb and flow method:

1.    Setup: The growing containers or trays are positioned on a table or bench. The containers usually have holes at the bottom to allow drainage.

2.    Fill and flood: The containers are filled with the growing medium, such as expanded clay pellets or rockwool, which support the plant roots. Then, the table or bench is flooded with the nutrient solution, which is pumped from a reservoir or storage tank. The nutrient solution should cover the entire growing medium, saturating it.

3.    Nutrient absorption: As the table or bench floods, the plant roots absorb the nutrient solution along with oxygen. The nutrients in the solution provide the essential elements needed for plant growth.

4.    Drainage: After a specific duration, usually a few minutes, the flood is stopped, and the nutrient solution drains back into the reservoir or storage tank. Gravity or a pump system can be used to facilitate the drainage.

5.    Resting period: Once the flood is drained, the plants have a period of rest where they are exposed to air. This allows the roots to receive oxygen, promoting healthy growth.

6.    Cycling: The flood and drain cycle repeats at regular intervals, such as every few hours or several times a day, depending on the plant's requirements and the system's setup. The timing and duration of the flood and drain cycles can be adjusted for optimal plant growth.

The ebb and flow method provides plants with a periodic supply of nutrients and oxygen, creating an environment conducive to rapid growth. It is a flexible and versatile hydroponic technique suitable for a wide range of plant species and can be used in both small-scale and large-scale growing operations

The ebb-and-flow, also known as flood and drain, is a hydroponic system technique used for growing plants. The purpose of the ebb-and-flow system is to provide periodic flooding and draining of the plant roots with nutrient-rich water. The cycle typically involves flooding the growing tray or container with the nutrient solution, allowing the roots to uptake water and nutrients, and then draining it away.

The ebb-and-flow system serves several purposes:

1. Nutrient uptake: By periodically flooding the growing medium or container with a nutrient solution, plants can absorb the necessary water and nutrients they need for growth. This helps ensure that the plants receive an adequate supply of nutrients for healthy development.

2. Oxygenation: During the flooding phase, the roots are submerged in water. When the water drains away, it allows for the replenishment of oxygen around the roots. Oxygen is vital for root respiration and the prevention of anaerobic conditions that can harm the plant roots.

3. Prevention of waterlogging: The ebb-and-flow cycle helps prevent waterlogging of the roots by allowing excess water to drain away. This promotes healthy root growth by providing a balance between nutrient uptake and oxygen availability while minimizing the risk of suffocating the roots.

4. Irrigation and hydration: The ebb-and-flow system provides an effective means of irrigating the plants. The flooding phase ensures that the growing medium is thoroughly hydrated, enhancing plant growth and overall moisture management.

5. Nutrient circulation: The periodic cycling of the nutrient solution helps maintain proper nutrient circulation and prevents the buildup of salts and nutrient imbalances that can occur in stagnant systems.

Overall, the ebb-and-flow system provides an efficient way to deliver water, oxygen, and nutrients to plants in a controlled and optimized manner, promoting healthy growth and optimal plant.
