Buying Guide
- Texture and preparation: Choose blends with ready-to-use moisture retention and aeration, or bricks/bricks that require expansion. Consider how much effort you want before planting.
- Moisture retention vs. drainage: Coconut coir typically retains water well, but blends with perlite provide better drainage for plants sensitive to overwatering.

- pH and nutrient considerations: Neutral pH and high CEC support a broad range of crops; some products come pre-buffered with calcium for pH stability.
- Intended use: Hydroponics, seed starting, or potting mixes may benefit from specific textures and additives; match to your plant type and growing method.
- Certification and labeling: OMRI-listed options are preferred for organic gardens; check for certifications if your project requires them.
