How long does HolidayGrow stay active in the substrate?

Long-term effect in the soil

HolidayGrow can stay active in the substrate for up to 3–5 years. During this time, the gel can absorb water and release it again and again.

Biological breakdown over time

Over the course of use, the material goes through a gradual structural weakening. After that, the gel slowly breaks down biologically – without harmful residues.
