    Rockwoll is often used to root cuttings (though I personally have found this method worthless.) I would guess you could mix it in to any mix requiring LFS as the properties are somewhat similar. That being said I would recommend you only try the mix on an expendable plant incase things go wrong

    Thanks Ozzy, i heard on the listserv once that even the managed farms tend to get pitcher plants in the spaghnum, but i agree it's still disturbing. I personally try to err on the side of the sand /perlite in mixes, for the very reason you mention.

    So, if rockwool has similar properties to lfs spaghnum, why is it not more commonly used? It seems, considering the topic in question, that it would be a good alternative. Just wondering. I've not been using it long enough to get any feel for how well it works. All i know is that it looks just like that fiberglass insulation that is supposed to be so dangerous for your skin and respiratory tract!

    One important thing to remember when using rock wool it is recommended that you first condition the rockwool before using it as a media. Conditioning consists of soaking the cubes for 24 hours in an acidic solution.
    This removes any impurities and corrects the ph of the cubes.

    Coir is the true media of "tomarrow".

    Thanks Khai, i didn't know that about pretreating rockwool.
    Why is coir better than eg rock wool? Just curious.

    One problem with coir, that I noticed a few weeks back, I can't find any. I looked at Lowes and every greenhouse I could think of and everybody looked at me like I was crazy when I asked for it. I gave all the names I could think of, cocopeat, coir, coconut husk. That didn't help either, I think it confirmed to them that I was crazy.
    Only thing close I could find was the coconut lining for hanging baskets.
    Let me know how the rock wool turns out.

    Rockwool is not used as an alternative because it is pretty expensive when compaired to LFS. It is also a lot more difficult to come by, I have never seen rockwool in a nursery while LFS is in every Lowes/Home Depot.

    Is rock wool rot proof? That alone would make it ideal in my book--set up the terrarium and forget it.
