What is the nutrient solution for soilless cultivation of flowers?

The stock solution of nutrient solution is the most basic nutrient solution for cultivating flowers, and the concentrated solution is the nutrient solution concentrated by how many times for the convenience of storage and carrying, such as concentrated by 100 times, 200 times and 1000 times. The concentration factor is formulated according to storage needs. The diluent is a nutrient solution obtained by diluting the concentrated solution with water according to the growth needs of various flowers. General diluent refers to the concentration diluted to the stock solution, such as concentrated solution concentrated 100 times, diluted 100 times and back to the stock solution, if only diluted 50 times, the concentration is 50% greater than the stock solution. Diluent is sometimes diluted according to the concentration required for the type of flower and the growth period, so the diluent cannot be regarded as the original solution. It can be said that diluent is culture solution, and some are called culture solution or working solution. Because the purpose of dilution is cultivation.
