Specially selected and hand-mixed best ingredients to produce fast draining soil that helps protect against root rot, the number one killer of indoor plants. Houseplant chunky mix contains the most organic matter of the soils we carry to ensure that your houseplants get all the moisture and nutrients they need to thrive. This mix utilizes recycled coconut chips and coir, an otherwise wasted byproduct of the coconut industry. Of the 50 million coconuts produced around the world each year, about 85% of the husks are discarded as trash.  We also carry a 1 gal size.  See separate option & pricing.
