Long Fiber Sphagnum Moss, or LFS for short, can hold up to 10x its weight in water. Making it the ideal choice for net pots, adding moisture to your existing soil, or as a top dressing in pots to reduce evaporation. The long strands make it easy to work with when mounting plants, and will keep it from coming out of the net pots or pots with large drainage holes. LFS can even be used for orchids and some carnivorous plants as the only growing medium.
