Growing hemp at home can be a challenging process, requiring careful control of the environment. One of the key factors for success is maintaining optimal temperature and humidity. In this article, we will explore how to create ideal conditions for hemp growth at home.

Optimal Temperature

Temperature is one of the major factors affecting the growth and development of hemp. This plant, originating from tropical regions, requires relatively high temperatures for normal development.

Air Temperature

For optimal hemp growth, the air temperature should be in the range of 21 to 27 degrees Celsius. Temperatures below 21 degrees slow down growth, while temperatures above 27 degrees can cause overheating and burns. During seed germination, the temperature should be between 18 and 25 degrees Celsius, ensuring rapid and healthy sprout growth. After transplanting the plants into the soil, it is recommended to lower the temperature to 18-22 degrees Celsius for the first 2-3 days to help the plants adapt and avoid stress. Nighttime temperatures should not drop below 18 degrees Celsius, as this can slow down growth.

Soil Temperature

The optimal soil temperature for hemp cultivation should be in the range of 20 to 24 degrees Celsius. Lower temperatures slow down root growth, while higher temperatures can cause overheating.

Temperature Measurement

To control temperature, use a thermometer. There are mechanical and electronic models, some of which can be connected to sensors for automatic temperature regulation. It is important to monitor the thermometer and hygrometer readings to maintain optimal conditions. Temperature or humidity changes can lead to overheating, mold, or slowed growth.

Methods of Maintaining Optimal Temperature

To maintain optimal temperature, you can use infrared lamps, heaters, and air conditioners. It is important to ensure good circulation of fresh air using fans and regular ventilation. One effective method is to use heat mats under plant pots.

Temperature Impact on Different Growth Stages

The temperature regime should be adjusted depending on the plant's growth stage.

Early Growth Stage: In the first weeks of growth, the optimal temperature is 20-25 degrees Celsius. Deviating from this range can slow down growth or even lead to plant death.
Vegetative Stage: During this period, hemp grows actively and requires a higher temperature - 22-28 degrees Celsius, with the optimum for most varieties being 22-25 degrees.
Flowering: During flowering, hemp becomes less sensitive to temperature changes. The optimal temperature for flowering is 20-26 degrees Celsius.
End of Flowering: After flowering is complete, the temperature should be reduced to 16-22 degrees Celsius.
Ripening Phase: In the final ripening stage, the optimal temperature is 15-20 degrees Celsius. High temperatures can worsen the quality and quantity of the harvest.

Optimal Humidity

Air humidity is also an important factor in hemp cultivation. Insufficient humidity can lead to drying out and plant diseases, while excess humidity can lead to fungal infections and mold.

Humidity Control

To control humidity, it is necessary to regularly measure its level using a hygrometer. The optimal humidity level for hemp cultivation is 40-60%.

Methods of Measuring Humidity

Hygrometer: This device measures air humidity. Place it near the plants for accurate readings.
Visual Assessment: Condensation on walls indicates high humidity, while dry plants indicate low humidity.
Paper Towel Test: Place a paper towel on the soil in the pot. If it remains dry, the air is too dry. If it's wet, the air is too humid.
Humidity Sensors: These devices can be installed near the plants for continuous humidity monitoring.

Maintaining Optimal Humidity

To maintain optimal humidity, you can use humidifiers, dehumidifiers, and fans. These devices will help create ideal conditions for hemp growth and development.

Conclusion

By following these recommendations for maintaining optimal temperature and humidity, you can ensure healthy hemp growth and high yields. Also, remember to consider other important aspects of cultivation, such as variety selection, soil quality, fertilization, and lighting, to achieve the best results.
