This DIY mix is handmade and composed of high-quality, mineral stones that includes 3/16" small grain horticultural pumice, 1/8"- 3/16" horticultural red/black lava rock & zeolites. You'll receive 3 pounds or about 10 cups.
 
NOTE: We may occasionally include a larger size pumice stone up to 1/8" in size mixed in.
 
The pon will be sifted to remove dust. We recommend rinsing before use. This mix contains no added fertilizer.
