    Thats an interesting growing method. Where do you get Osmunda by the way? I have always read about how it is great stuff that everyone used 50-100 years ago, but that it basically ran out.

    Hi Dave, In my past orchid life I bought many bails of shredded Osmunda and still have a good supply.
    But here in the highlands of northern NJ it's easy to responsibly harvest it from the woods, Osmunda fibre is the dead root mass of the Osmunda fern " Osmunda regalis " you can saw it out of the ground in chunks without killing the fern.

    Hi Mike, I have to build an orchidarium for a presentation to my society... Can I ask where you got your materials, especially the misting heads?

    Lovely and impressive collection. What is the theory about the oak leaves?

    Hi Mika,
    The Oak leaves add Tannin compounds to the water which have natural anti bacterial, anti microbial properties
    and they also release trace minerals that have been chelated for absorption by plant tissue. use only dry brown leaves, put them in a mesh laundry bag and hang it in your water tank, replace them once a month.

    Thank you for the explanation Mike. I might test that.

    Hi Mike, do the flowers open up with the green venation, or does this appear over time?

    The green venation is evident within a few days.

    Mike, what's the temperature range that you keep your tanks at?

    Mike, I totally copied you and have received my division of this from Darrin. I just love it! I'd say the flowers actually have four colors. Awesome! Thanks for the thread.
