Here are some advantages of using biostimulants in horticulture:

1. Improvement of the efficiency of nutrient uptake by plants, resulting in better growth and larger yields.

2. Accelerate the growth of roots, shoots, and flowers, resulting in enhanced plant development and maturation. 

3. Improve plant health because it boosts plants' natural defense mechanisms, making them more resistant to pests and diseases. This has the potential to reduce the needs for chemical pesticides and fungicides.

4. Frequently less expensive than other plant treatments like chemical fertilizers or insecticides. They can also eliminate the need for multiple treatments, saving both time and money.

5. A more sustainable solution by lowering the environmental impact of farming and improving crop health and yield.
