High-quality, lime-free quartz gravel ensures a balanced water capacity in the substrate. Due to its property of quickly absorbing water but also releasing it quickly, quartz sand provides an excellent additive for adjusting the moisture level for a range of different substrates. In comparison to quartz sand, gravel absorbs significantly less water and therefore promotes substrate aeration even in small amounts. Now new in a resealable pressure-seal bag!
