Poly terrazzo pots is a common material for contemporary planters due to its light weight strength and durability. Like Terracotta it is permeable to water, allowing water to pass through the pot, which aids evaporation from the soil, decreasing the chance of root rot. This permeability can lead to discolouration of Poly pots over time but pots that have been painted are less likely to suffer discolouration. Lightweight terrazzo pots is often mixed with fibres to provide extra strength in larger sized pots. Depending on the composition Poly terrazzo pots can be relatively lightweight and therefore easier to move around.
