Buying Guide: Key Considerations For Coco Chip Substrates
- Expansion and weight: Bricks typically expand 4–7 quarts per brick. Larger expansions reduce the number of containers you need to manage.
- EC and pH balance: Low EC and a stable pH (usually around 5.5–6.5) help prevent nutrient burn and improve nutrient availability.
- Moisture management: Coco chips retain moisture well but require appropriate aeration to avoid root rot. Consider mixing with perlite or charcoal for better drainage.
- Best use scenario: For seed starting and small pots, smaller bricks are convenient; for gardens or larger planters, 10 lb bricks or multi-pack options simplify bulk use.
- Compatibility: Coco coir substrates work across many plant types but may require adjustments when mixing with soil-heavy mixes or hydroponic setups.
