The best hydroponic system for growing cannabis usually includes the following key parts:

‌Seedling stage‌: Use a mixture of sphagnum moss, peat and fertilizer as the seedling substrate, and select cannabis seeds with full grains for spot sowing. Place the sown substrate blocks in the tidal seedling bed for seedling raising.

‌Transplanting stage‌: Place the seedling strip substrate blocks into the floating board holes, with a planting density of 18 trees per square meter. Oxygenate the nutrient solution 24 hours a day to ensure that the oxygen content in the water is greater than 6mg/L. Strictly control and adjust the hydroponic nutrient solution, cooperate with environmental regulation, and cultivate accurately.

‌Growth period management‌: During the growth period, the hydroponic nutrient solution needs to be strictly controlled and managed to ensure that the composition and concentration of the nutrient solution are suitable for the growth needs of cannabis. At the same time, environmental regulation, such as temperature and light, is required to provide the best growth conditions.

‌Maturation period management‌: During the maturity period, continue to manage the nutrient solution and environmental regulation to ensure that the cannabis can mature smoothly and achieve high yield and high quality standards.

‌Advantages of hydroponic system include:

‌Water and fertilizer saving‌: Hydroponic system can accurately control the amount and composition of nutrient solution, reducing the waste of water and fertilizer.

‌High and stable yield‌: By accurately controlling the growth environment, high-yield and stable medicinal cannabis can be obtained.

‌Environmentally friendly‌: Hydroponic system reduces the use of soil and reduces environmental pollution.

‌Disadvantages of hydroponic system include:

‌Large initial investment‌: Establishing and maintaining an efficient hydroponic system requires a certain amount of capital investment.

‌High technical requirements‌: Professional knowledge and skills are required to operate and maintain the hydroponic system, especially the management of nutrient solution and environmental regulation.

Through the above steps and precautions, an efficient cannabis hydroponic system can be established to achieve high-yield and high-quality planting goals.
