All Cultilene media products allow plants excellent root penetration, optimum drainage and good water movement due to the small fibre diameter in the rockwool. Cultilene products are all pathogen free and are renowned for holding their shape once soaked unlike other blocks on the market. Whenever transplanting into the block always pre-soak them in a solution with a pH value of around 5.8 and allow excess solution to freely drain away.
