Which is better vermiculite or Perlite..
Hey gang...I cannot readily find vermiculite; but I find perlite easily in local stores. Can I replace vermiculite with Perlite. I heard that vermiculite last for 2 years, until it decomposes, then you have to add it again. However perlite lasts for a long time. Also vermiculite, could have some asbestos, or, asbestos like material/fine dust that could cause some breathing problem down the road. That is why some of the stores quit carrying it. I understand, that only one mine was contaminated, other than that I have not heard anything.
Can you give me some expert opinion on this?
Is vermaculite better than perlite? Do they have same benifits? Are they interchangeable?
Thanks for your response.
