Hello! I'm a bit curious about the types of media (rock wool from Grodan, coco coir, etc) available to grow Marijuana, so I have a few questions!
  1. What type of growing media do you use and why?
  2. For Grodan's products or other types of rock/mineral wool, what issues have you come across?
  3. How do you dispose the growing media when you?re done?
  4. If you use mineral wool, what percentage of your cost goes into buying mineral wool

Hoping to hear from someone!
