Had no idea that so many grades are now available! I bought some compressed
into a brick...I was hoping for the long hairlike kind but it was a bit
like peat really....but finer.
Since I use 2 mm quartz sand, grit 3-4 mm and some crushed
bricks....stability really isn't a problem here :-)
The mix IS light....I also add some crushed expanded clay spheres ( called
leca here used in hydroponics) so the roots get more air.
It was interesting to repot...I haven't repotted for the past three years
due to some sudden changes in residence, and some plants had waited longer
than that...I could tell merely by looking at the root systems which had
been sitting in a gritty mineral substarte and which had been sitting in a
Besides, I top up my pots with aquarium gravel of different sizes for
estethich purposes and to provide that extra bit of drainage around the
The juvenile Pel seedlings look happy in this...really they do. The Sarc
seedlings do too...no sign of fungus or anything.
But I will bear it in mind.....usually my C&S pots sit together so toppling
over isn't much of a problem.
