Nutrient substrate for rearing beetle larvae, also suitable for many millipedes, land crabs, and snails. For each species, it is recommended to mix Beetlefix 1 with Beetlefix 2 and/or Black Soil. Fill the stable rearing box with Beetlefix 1 to a height of at least 5 cm. There must be a free space of at least 5 cm above the substrate. The optimal rearing temperature is between 20° and 26°C. If necessary, the mixtures should be adjusted with Beetlefix 2! Depending on the species, it may be necessary to supplement and moisten the cultures during the rearing process. It is important to ensure adequate ventilation.
