When the medicinal plants seedlings are transplanted to the tent, in order to ensure that the leaves of the plants can get enough light and plants grow rapidly, multi-function LED lights should be used for lighting, and the LED lights should be hung in the tent.
The height of the leaf surface (canopy) of hemp plants is 50 cm. The red and blue light spectra are opened, and the light quantum flux is set densely. (Light intensity) is 100umol ∕ ㎡s, when the medicinal plant is 3-5 cm high, the LED lamps should also be the height should be 3-5 cm to prevent the young leaves from being burned by strong light. When the medicinal plant is more than 20 cm,the lamp can be raised to a height of more than 60 cm from the leaf canopy of the seedlings, and the light intensity can be set to 150umol ∕ ㎡s. In the tent, the light period is set to 18/6, that is, the light period is 18 hours, and the dark period is 6 hours. It is advisable to control the temperature in the tent between 19-25 ° C. The relative air humidity is 40-60%, and the pot soil humidity is about 50%. When the pot soil is dry, water it in time. Available when plants are deficient. Apply nutrient solution or spray nitrogen, phosphorus and potassium liquid fertilizer outside the root. Method: use 100 g potassium dihydrogen phosphate + 50 g urea. Foliage sprayed with 50 kg of water and sprayed every 7 days, or fertilize depending on the growth of the hemp. when you have mastered the above management points. Medicinal plants LED light tent planting must grow fast and well.
