R&R SHOP – Medium Black Lava Rocks, 100% Natural, pH Neutral, Ideal for Drainage and Plant Growth, 10–20 mm (5L)

• Dry matter: 90%
• Total porosity: 70%
• Water retention: 100 mL/L
• pH: 7.0
• 🌍 ORIGIN: Extracted and selected in Italy from basaltic volcanic rocks, naturally rich in iron and magnesium. This gives them their dark colour and high absorption capacity. The crushing, screening and washing process ensures a clean, stable and 100 % natural material, ideal as an inert soil amendment or as a substrate for hydroponic systems.
• 🌱 PLANTS: Thanks to their properties, lava rocks provide excellent absorbency, reducing watering frequency and storing nutrients supplied by fertilisers without altering the pH, while at the same time oxygenating the roots. Particularly useful in the early growth stages and for cutting propagation.
• 🛠️ USE: For an ideal mix, add 10–20 % lava rocks according to the required aeration of the substrate.
• ♻️ COMPACT SIZE: Thanks to the compact packaging, the product is practical and space-saving. Supplied in a resealable press-zip pouch.
