The sunshade net must be placed outside the shed, and the sunshade net should be removed sooner or later after emergence, so that the seedlings can be seen more without forming high temperature(9cm plastic grow pots). It is not possible to cover the shade net on the tray and not the shade net outside the shed. Due to the inconsistent seed germination potential or the low germination rate, the seedlings are not uniform or the growth is inconsistent.
Spread in the substrate or in the soil, seedlings can be divided into seedlings(black plastic nursery pots). It is easy to seedling under conditions of high temperature, high humidity and low light, and can be sprayed with an aqueous solution (pure product) of 10,000 to 20,000 times of ketamine, and sprayed once more every 7 days. Due to the high temperature in summer, the evaporation of water is large, the matrix loses water quickly, and it is prone to wilting, which affects the normal growth of seedlings(90mm plastic grow pots). It should be replenished immediately, but watering in the high temperature section should be avoided.
