1. Light: just after sowing, it is better to put it in a cool place. After germination, you can give light. However, this is a step-by-step process, which cannot be given strong light at the beginning. Just sprouted seedlings are still relatively weak, at this time can receive light in the morning, and can be separated from the glass, but do not cover the quilt, so it will be hurt because it is too hot.
2. Ventilation: necessary ventilation is required at this time. However, because the seedlings are very weak, so we can't have too much wind, otherwise it's easy to blow them down
3. Watering: within one month of germination, it is better to use "soaking basin method" to supplement water. Because the normal watering method is easy to wash down the seedlings. But when it grows up, it doesn't need to use this method. Just water it with a watering can. The interval of watering can be adjusted according to the condition of the substrate. After the substrate is dry, make up water in time.
4. What to do about lodging: the seedlings are relatively easy to lodging. When this happens, you can hold them up with tools and sprinkle fine sand to fix them.
After germination, it can be transplanted. Attention should be paid to the use of soil, which can be prepared with peat soil, perlite, red soil and fine sand, and needs to be disinfected before use. Prepare a small clip, dig out the seedlings and move them to a new basin.
