Lechuza pon plant substrate is the perfect alternative where conventional soil cannot or should not be used. Lechuza-pon is 100 percent suitable for all plants. Consists of high quality, mineral stones, that are free from contamination and pollutants. Lechuza-pon has the optimal air/water ratio for plants of 45 percent water/55 percent air. The vulnerability to diseases is reduced. Even after some time, the structurally stable plant substrate does not condense and it keeps its air permeable structure. The multiple filtering in production reduces the fine particles in the substrate to a minimum. This prevents a silting up in the root area and sustains a long-lasting capillarity. The substance zeolite stabilizes the ideal PH balance for a healthy plant growth in your lechuza planter. Macro and micronutrients remain permanently. Comes in 12 liter.
