    Default S/H fuzziness what do I do?

    I've had this guy in S/H for a while so both the new growths are used to the S/H (I hope). The media has been fuzzy like this for a while and rinse twice when watering every week or so (in the winter). I'm thinking of taking the plant out and properly flushing and cleaning the media but I'm worried about disturbing the new growths, what's the best thing to do in this case? It doesn't look like the plant is being harmed but I'm quite worried for the new growths.

    I have never had this happen but I suspect it is from the dead material (old roots ect) Being the medium is inorganic, then it must be from dead living material. What I would try is doing a Physan soak followed by a thorough rinse. Cover the drainage holes...soak 15 or 20 mins...drain and rinse thoroughly a few times.

    Being I am not an expert on this, get other opinions prior to trying my suggestion. I believe it is what is called "snow mold"

    I only have 3 orchids in S/H. I find it easy to pull the whole plant out, pour out clay balls and clean up algae and dead roots in the pots. I do it maybe every two month or so. I haven't seen any mold since.

    How do the plants respond to this frequent repotting?

    They didn't complain Repotting in S/H seems a lot easier than regular bark, roots are attached to some clay balls, but not to pot, so it's easy to pull the plant out.

    I agree with Ron. Run some Physan through that pot. First, flush the pot with lots of fresh water. Let it run and remove as much decaying material as you can. Next, sit it inside another container that doesn't drain and let it soak in a Physan mix for 15 - 20 min. Let it drain normally and keep an eye on it.

    Cheers,

    One possible problem for Richard--Physan is not readily available in Canada. Any suggestions for substitutes?

    Cheers,

    You could try hydrogen peroxide.

    That I was unaware of. Richard, there was a prior post on this forum that you may find helpful

    http://www.rv-orchidworks.com/orchid...ng-fungus.html

    You could also try a bleach solution...Bleach at 1 ounce per gallon of water
