TKL - High Quality Red Lava Rock / Volcanic Stone 0.1-0.3mm (700g) 火山石

This lava rock is made up professional formulation which keep its well drainage and also supply the necessary nutrition for plants growing. It is best for succulent hobbyist and other succulent lovers. 

Function: 

• These lava rocks are all natural and organic. 

• Ideal for pots with no drainage holes you can place the lava rocks at the bottom of the planter so the water can pool without drowning the roots. 

• Lava rocks are porous and will absorb and slowly release excess water back to the plant. 

 • Perfect for preventing root rot. 

 Benefits: 

• Lightweight – lava rock is quite lightweight because of the air pockets in it. Its lightweight makes it ideal as mulch because it does not sink into the soil, nor does it compress it. It lies on the surface, protecting it from the environment while allowing it to maintain its structural integrity. 

• Porous – Lava rocks porosity allows for better drainage. It ensures water does not pool between the rocks or under them, which prevents fungal growth keeping the yard healthy. 

• Protects the soil – When used as mulch, lava rocks also prevent soil erosion while allowing all the nutrients to seep through. It also slows down evaporation from the soil, which can drastically reduce watering needs for your yard. 

• Weed Suppressor – By adding a fabric weed barrier beneath the layer of lava rock mulch, you can effectively protect your grass from a weed invasion for a very long time. 

• Low maintenance – Unlike organic mulch, lava rock does not disintegrate or decompose. It lasts a very long time and requires almost no maintenance. Add it in your yard and forget about it. You don’t even have to worry about replacing it for a while. 

• Available in Different Colours – the reddish-brown lava rock can add a much-needed pop of colour to the yard. Though it may not be for everyone, it is quite a popular option for many landscape designers, especially in desert regions. For those who don’t like red could always opt for the greys and the blacks to add earthier tones in the yard. 

描述：火山石是一种功能型环保材料，是火山爆发后由火山玻璃、矿物与气泡形成的非常珍贵的多孔形石材，火山石中含有钠、镁、铝、硅、钙、钛、锰、铁、镍、钴和钼等几十种矿物质和微量元素，无辐射而具有远红外磁波，在无情的火山爆发过后，时隔上万年，人类才越来越发现它的可贵之处。现已将其应用领域扩大到建筑、水利、研磨、滤材、烧烤炭、园林造景、无土栽培、观赏品等领域，在各行各业中发挥着无法替代的作用。火山石有黑红两色，总体上不太适合怕热的多肉，因为其颜色较深，吸热能力强！特别是夏天！而且由于火山石透气性太强，许多小苗或者根系较少的多肉，新长出的根系还没扎进土里，就因为缺水干枯了，因此也不适合刚刚生根或者根系较弱的多肉。 

功效: 增强土壤透气性，改善土壤结构；其次就是吸附水中的有害细菌，重金属离子如铬、砷等，还可以吸收一些家用自来水中残留的氯；再者就是火山石含有的微量元素和矿物质能促进生长，增强免疫力，大孔隙能培养硝化细菌等 

功能: 火山石还是一种很好的缓冲物质，能在一定范围内调节土壤 pH值。火山石带有气孔，透气性极好，而且比较坚硬，不会变形，不会粉碎，比较适于石莲类及带桩多肉。
