Flowering hardeners are hydroponic supplements that are designed to promote the growth and development of ornamental plants during the flowering stage. These products are formulated to help plants produce more flowers, increase flower size, and improve the overall quality of the blooms.

Flowering hardeners work by providing plants with a range of essential nutrients, such as phosphorus and potassium, that are critical for flower development. They also contain other beneficial compounds, such as amino acids, vitamins, and plant hormones, that can help to improve flower quality, increase oil production, and enhance plant resilience.

It is important to note that flowering hardeners should only be used on ornamental plants and not on plants that are intended for human consumption. This is because these products may contain ingredients that are not approved for use in food crops, and could be harmful if ingested.
