About this item This extra‑coarse gardening vermiculite stays stable, tidy, scent‑free, non‑toxic, bacteria‑free and pH‑neutral. It will not degrade, get mouldy or decay. It can be blended with planting soil, peat, pine‑bark compost, fertilizer and plant‑care chemicals, speeding‑up root development and helping seedling roots take hold. The coarse‑grain vermiculite possesses natural water‑absorbing capacity. Its particles trap ammonium, potassium, calcium and magnesium essential for plant growth. Mixtures made from vermiculite and peat maintain good air permeability, while storing moisture and nutrition. Plants absorb required moisture, air and mineral substances on demand, cutting down maintenance work, improving plant health and boosting output. The grains are capable of absorbing water exceeding three‑times their bulk. Therefore, the substance suits pump‑free passive hydroponic planting systems. It also works great for seed sprouting and cutting propagation. Product: Extra‑coarse horticultural vermiculite
