Grodan or rockwool challenges

@devjyarn thank you so much for these thorough answers - so incredibly helpful! A few follow-up comments and questions:

  1. From what I’m seeing, Grodan seems to be the dominant name when it comes to Cannabis but am aware of other brands in the hydroponics space like Cultilene. When it comes to Grodan for cannabis, are you aware of any issues with the product or with distribution?
  2. Interesting - I actually didn’t realize rockwool was compostable. From my understanding, I thought a pain point for larger growers was how to get rid of rockwool after their grow since it’s often a single use product (I heard some growers paid to get it dumped or would just discard it somewhere on their property). I was thinking from sustainability in a few different ways, first being the actual method of discarding the product at the end of life. Other thoughts were surrounding packaging and overall efficiency of resources compared to other products. If it’s compostable, the first part about the end of the product life isn’t as much of a pain point as I thought.
