Does the bowl lotus need to be water changed after germination?
The germination of the bowl lotus marks the entry into a new stage of planting, and scientific water management directly affects the quality of seedling growth. This article will systematically analyze the key points of bowl lotus maintenance after germination from dimensions such as water quality control and light requirements.
Bowl Lotus Germination Water Management
Principles of Water Change Frequency Control
After the bowl lotus seedlings break through the shell, the water change frequency can be reduced to 1-2 times per month. The key is to maintain water transparency >30cm and no oil film floating on the water surface. If the water is turbid and green, has a fishy smell, or breeds mosquitoes and flies, a full water change is required immediately.
Scientific Water Change Procedures
Before changing the water, prepare water that has been sunned at the same temperature, with a temperature difference within ±2°C. During operation, retain 1/3 of the original pot water and slowly inject new water to avoid shocking the seedlings. It is recommended to change the water in the early morning and clean the algae from the inside walls of the container.
Key Points of Bowl Lotus Water Quality Control
Water Quality Selection Standards
Only use slightly acidic soft water with a pH of 6.5-7.5, and tap water needs to be aerated for more than 48 hours. Regularly check the EC value, keeping it within an ideal range of 200-400μS/cm. Do not use rainwater, distilled water, or other mineral-deficient water sources.
Water Quality Maintenance Tips
Add 1 piece of activated carbon per 10 liters of water, which can absorb impurities and keep the water clear. It is recommended that the diameter of the planting container is >30cm, with a water depth of 8-12cm, as too shallow can cause drastic water temperature fluctuations.
Bowl Lotus Seedling Maintenance System
Light Intensity Management
The seedling stage requires ensuring 4-6 hours of direct sunlight daily, and a 30% shade is needed at noon in summer. Use a light meter to test, and the light intensity should be maintained at 10000-15000lux. If the light is insufficient, supplement with full-spectrum plant lights for 2 hours daily.
Plant Food Application Standards
Begin fertilizing 15 days after germination, using a hydroponic special nutrient solution with an NPK ratio of 5-10-5. Add 0.5ml per liter of water, supplementing once a week. If leaf burning occurs, change the water immediately and dilute.
Through scientific water changing and systematic maintenance, bowl lotus seedlings can grow floating leaves within 30-45 days. Regularly observe the water condition, combined with temperature and light control, to allow the bowl lotus to successfully complete the nutritional growth stage.
