Styrofoam-Flakes

Styrofoam flakes are affordable, easy to obtain and have excellent drainage abilities. Though, they can be too light for some applications. Mostly they are used in closed tube-systems.



It has to be mentioned, that it is important to use Styrofoam flakes instead of bio-degradable packaging flakes, because those decompose over time and the plants absorb the remaining substance, which leads to a potential health risk.
