Can green lobelia be hydroponically cultivated?
This article introduces whether green lobelia can be hydroponically cultivated and provides detailed techniques for hydroponic care. Here is the comprehensive introduction.
When hydroponically cultivating green lobelia, it is necessary to change the water regularly. Initially, change the water every 2-3 days, and after the roots have formed, change it every 15 days. Provide ample diffused light, and for indoor cultivation, place it in a sunny area for care. Add 2-3 drops of nutrient solution when changing the water, and clean the container promptly when green algae appears. Also, prune the decayed roots timely.
I. Cultivation Environment
1. Water Change: Hydroponic green lobelia requires regular water changes. Change the water every 2-3 days when initially hydroponically cultivating and every 10-15 days after the roots have formed, ensuring the water does not become murky. Additionally, do not add too much water when changing it, leaving 1/3 of the roots exposed and avoiding contact between the leaves and water.
2. Lighting: Provide appropriate lighting, avoiding strong direct sunlight and ensuring it receives adequate diffused light. If grown indoors, place it in a sunny area or move it outdoors regularly for sun exposure.
3. Temperature: Hydroponic care requires a growth environment of 20°C, with temperatures not too high or too low. Low temperatures can cause frost damage. Also, avoid placing it directly in front of an air conditioner or near a heater.
4. Nutrient Solution: Regularly add a nutrient solution when hydroponically cultivating green lobelia, usually done when changing the water, adding about 2-3 drops each time. After starting the nutrient solution, green algae may appear in the container, so it should be cleaned promptly.
II. Precautions
When hydroponically cultivating green lobelia, pay attention to the root system. The roots grow quickly in water, and if they become too long, they should be trimmed appropriately. Also, roots in water can easily rot, and any decayed roots should be cleaned and cut off, and消毒 can be performed using potassium permanganate.
