Tanks Green Stuff - Pumice 16qt Bag

Horticultural Pumice for Soil Aeration & Drainage This lightweight, porous rock improves drainage and root-zone aeration, helping prevent overwatering and compaction. Its high surface area holds moisture and nutrients, releasing them gradually to support beneficial soil microbiology and long-term soil structure. Pumice for Cactus, Succulents & Houseplants Ideal as a soil amendment or growing media component, pumice enhances potting mix performance for cactus, succulents, and indoor plants—and can complement hydroponics and soilless mixes. Benefits: Improves soil drainage and aeration to prevent overwatering and root rot. Porous structure holds and slowly releases moisture and nutrients for steady root access. Supports beneficial soil microbiology and long-term soil structure for healthier growth. Lightweight, inert, and pH-neutral—won’t compact or break down; reusable across repots. Versatile amendment for cactus, succulents, houseplants, bonsai, and potting mixes (pairs well with coco, compost, or perlite).
