Protecting the substrate is very important for crops with a longer vegetation cycle, as unwanted grasses can grow on the substrate base over time, which would damage the crop. Research suggests that South African farmers spend an estimate of +- R40 000 / hectare annually on weed control. When weeds are removed by hand by farm labourers, growing media is spilled on the ground and accounts for more costs to the farmer.

It is a 100% natural protector, made of recyclable coconut fibre. The coconut fibre is treated with 100% natural rubber, sprayed to help maintain the disc’s shape. Unlike other protectors with the same use, it has enough consistency to protect properly, preventing evapotranspiration, but allowing ventilation.
