What are the key advantages of using stone wool over coco for cannabis cultivation?

  • Early flower production and shorter growth cycle
  • Greater yield of dry flower
  • Improved root quality and plant uniformity
  • More compact and higher potency flower
  • Excellent steerability of WC% and EC
  • Increased resistance to disease
  • Reduced labor and resources
  • Less water and nutrient usage
