Hi Michael,.

I had also once 2010 at gigas and decus-silvae. look here in post #41:
Mr. Titanum's collection

I had at that time asked Wilbert Hetterscheind for advice and he antowortete:
"Hi Bernard,

I know that, there are cracks that arise when a tuber in the full
Growth is suddenly taken from the Earth. Somehow there is then
too much internal pressure which comes out and the tuber "bursts" (as is frequently
at most. ochroleucus). Zein is not always a problem. I advise the
You tubers right back eintopfst and you could still a fungicide in
apply the cracks. Keep then again good moist, because that shall be
with gigas.
Good luck!

Bye,.
Wilbert"

I could also think that fluctuating substrate moisture could be a cause.

But as WH wrote, this is not necessarily a problem; may be that that is true but only on species, coming from immerfeuchten areas.
If I remember correctly, the tubers are grown at that time all...

Happy growing, Bernhard.

Hello

I was also extremely many of the "cracking" last Jahr(2015). The years before wars times 1 or 2 tubers, but this time it occurred while many tuberous.
Some tubers are even torn in the hand as gabs nen tore a loud noise and the tuber.
What it is I don't know well, but there were striking many tuberous 2015.Art plays no role when everyone, almost all big konjac tubers were this time also.

Maybe as a little hint - something on your CA supply look.
CA is Zellwandfestigend and can prevent such problems.

Generally, this is a much too little regarded nutrient...
