Why is Coco Coir Better Than Potting Soil for Indoor Cannabis?
Coco coir, a natural fiber derived from coconut husks, is increasingly favored by indoor cannabis growers over traditional potting soil. Here's why:
1. Aeration and Drainage: Coco coir's coarse texture allows for excellent airflow and drainage, promoting healthy root development and preventing waterlogging.
2. pH Stability: Coco coir has a slightly acidic pH, which is ideal for cannabis growth. It buffers pH fluctuations, reducing the risk of nutrient deficiencies or toxicities.
3. Humidity Control: Coco coir's moisture-retentive properties create a stable humidity environment, reducing the need for frequent watering.
4. Nutrient Absorption: Coco coir is rich in nutrients and easily absorbs and retains fertilizers. It also allows nutrients to be released gradually, preventing nutrient burn or leaching.
5. Disease Resistance: Coco coir is a disease-resistant substrate that does not harbor harmful pathogens, making it safer for plants and growers.
