In simple terms, "Wabi-Kusa" is a clump of grass that includes the substrate. Since it is grown in semi-aquatic conditions, it grows quickly with a well-developed root system, and its growth rate is faster than that of typical water plants grown above water. "Wabi-Kusa" simplifies the planting process by eliminating the need to plant individual stems or clumps. Instead, you just place the whole clump into the tank and arrange it according to the desired height and position for landscaping. It allows for an instant aquascaping effect. For an immediate landscape effect, aquatic "Wabi-Kusa" is undoubtedly a great choice.
