Standard BV50
Substrate with a high sphagnum peat moss content, which provides porosity, aeration and a high capacity to retain water. The sphagnum peat moss content provides a very suitable medium for growing acid-loving plants such as hydrangeas, camellias, rhododendrons, gardenias and azaleas.

BV50 NF
Substrate suitable for acid-loving plants grown outdoors, given that its NF property (the presence of coarse sand) makes it retain more water so the time between watering sessions can be increased. This NF property is important for substrates with a high sphagnum peat moss content that need to stay moist.
