Tips:

1. The seeds can be soaked in clean water for about 6 hours in advance, then put into the bottom of the hole of the fully soaked planting sponge, and turn on the fill light (different seeds have different soaking times).
2. In general, it is recommended to put 2 seeds into each cotton block for planting. During the seedling period, it is recommended to retain the good growing plants. The bad growing plants can be gently pulled out or cut off with scissors. It is recommended to retain only one dominant plant.
3. You can use the transplanting method to find a sealable box and clip the seeds between two pieces of soaked thick paper towels to avoid light
After being placed for 2 days (spray wet properly if it is dry during the period), use tweezers to transplant the budding seedlings. Be careful not to damage the primary root system. At this time, turn on the fill light directly without the seedling hood.
4. Please keep an eye on the initial germination of seeds. Lack of light and failure to remove the nursery cover in time may lead to
The plants are overgrown. Remove the nursery cover in time after the seeds germinate.
5. The nutrient solution can be added after the young seedlings grow leaves, and the water supply for the whole growth period thereafter shall be the water added with nutrient solution. Generally, the nutrient solution shall be added every 1-2 weeks, and the water shall be kept clean before.
6. Pay attention to the water level during the seedling growing period, which shall not be too high or too low; If the water evaporation is too low, it should be supplemented in time to avoid the influence of rapid drying on seed germination; If it is too high, the seeds will be soaked in too much water and become moldy; When the plant has a little more branches and leaves and roots are developed, the liquid level can be kept in contact with the plant roots, and the plant can grow normally.
7. The distance between the lamp board and the plant should be kept at about 10 cm to avoid scalding the plant branches and leaves.

Notes for first use:

When adding water for the first time, add water to the large water tank at the bottom to the highest water level, then turn on the water pump to fill water, wait until each small water tank above is full of water, and then add water to the large water tank at the bottom repeatedly to the highest water level.
Add nutrient solution for the first time. When the water pump is turned on, add nutrient solution in any water tank: 200 ml of nutrient solution in three layers (40 liters of water), 200 ml of AB solution (2 bottles each)
For the 4-layer model (48 liters of water), add 240 ml of nutrient solution at a time, 240 ml of AB solution each (2 bottles+40 ml each). If the water is reduced later, prepare a water container, and add 5 ml of AB nutrient solution each in the proportion of 1 liter, and then add it into the planter.
