The Growcoon bears the official OK biodegradable soil label, managed and controlled by TÜV AUSTRIA. The OK biodegradable SOIL label guarantees that a product is biodegradable in the soil without harmful consequences for the environment.
The testing for the OK Biodegradable Soil certificate has been carried out by an independent certified laboratory. The laboratory has shown that the Growcoon is biologically converted into CO2 and H2O and that no toxic substances are subsequently left behind in the soil.
The Growcoon already obtained the OK Compost Certificate in 2017 (guarantee that the Growcoon is biodegradable in an industrial composting installation) and is also on a list of permitted products for Dutch organic horticulture.
