Anyone seen this?
these hard lumps have shown up on some of my older roots, and usually layered under a white substance that's hard to remove... this pic is post clean up...

I can't help I'm afraid. Hopefully someone with an idea on this will see it soon.

MT,
Is this root firm or soft. Was it original to the plant or is it one that grew and developed after you repotted to S/H?
Maybe it's just in the process of dying off. How's the plant and do you currently have healthy roots?

this root is firm, and it was part of the original root system prior to the move to S/H. All the other roots died off a couple months ago.
My plant is in good shape, for now. My root system currently consists of root nubbins that are growing painfully slow. I'm about to put it back into coconut chips. S/H didn't work out :-(

MT-Phal I second you.
I have a C guttata. small. was puttong out new roots but then the tips would die off.
Same with some Onc NOIDS I got for a couple of bucks each.
What is working in S/H is a Laelia tenebrosa. ok roots but no new growths. and some sort of reed stem Epi. But for the most part I have not really been happy. I feel lava rock probably would work better than hydroton.
Or maybe hydroton has to be soaked for a week. Or maybe works well in a greenhouse or somewhere very humid.
I transferred almost all to cocounut and I can see the roots taking off growing through the medium.
I feel you need to keep LECA very moist and for me it dried too quickly. Probably i would have had to mist it twice a day.
I think a way that could work better for S/H probably filling 2/3 of the container - or maybe half with LECA and top it off with coconut chips.

stefpix,
Yeah, I attribute my s/h failure to bad timing. I repotted as new growth was appearing, but I did not expect the winter to get as cold as it did in California this year. As my new apartment doesn't have central heating and I waiting far too long to get a room heater, the cold temperatures in my room were probably the cause such slow growth. And then as the roots began to rot, suddenly there was an outbreak of mold that I couldn't really control.
maybe next time...
as for my current phal, it will be back in coconut in a few days. Since it will have so few roots, I'm going to do a half PA and half coconut to avoid having a soggy bottom.

Hi MT the little hard white growths are a fungus, and it means the root is on its way out, i'm sorry to say.
Yeah obviously repotting coming into the growing system is the best bet with S/H. I think now that you've got it there you might as well leave it there, going back to coconut husk will only be another shock.

i think it is more of a shock a medium that the roots dont like. the roots of some plants refused hydroton and where going upwards or getting dark/dry tips. no such problems with coconut chips.
leave a plant in the wrong medium it will eventually die.
actually at the hydroponic store they sell coconut as a hydroponic medium.
In my experience my success rate in coconut chips is way higher than hydroton.

Cold was your problem (probably stefpix's too).
Don't forget that there is a fair amount of evaporative cooling that can occur in a dry environment, and some plants are quite intolerant of it. Allow the temperature to get down too, and it exascerbates the issue.
