How often do you repot?I don't grow kovachii but I do use a coconut husk based media for my Paphs and Phrags. It's a mixture of small and medium CHC, large perlite and horticultural charcoal. I've been using this mixture for years and have had good luck with it. Good aeration but holds the moisture.
Your answer gives me courage because I heard mostly negative things about coco husk. ThanksI have pretty good success growing not just paphs, but just about everything under the sun with coco husk including all sorts of tropical plants. I mix it with perlite and peat, along with some broken terra cotta pieces for anything that needs some extra airflow. Even my phals seem to like it, although I give them a few big chunks of bark to cling to inside their pots.
Thanks! I already soaked the coco husk once. I shall do it 3 times to be sure.Repotting, generally every other year. Maybe one of the bad things you've heard had to do with the salt content, even with the stuff that is "pre-rinsed". I generally give it a soak in at least two changes of RO water and another of rain water and than check the hardness of the resulting rinse water before I use it for my mix.
My experience too with Paphs, CHC stays too wet.everytime i try using coco things die; the alternate opinion. It stays too wet, for me.
Have you considered semi-hydroponics with cymbidium?My experience too with Paphs, CHC stays too wet.
Having said that, I was looking for a new medium for growing Cymbidiums as it is basically impossible to find a good cheap Cymbidium mix in Australia at the moment. So I have just started trying a CHC mix. Given Cymbidiums love being wet, I am hopeful it will work out well.
Thanks Ray. I hadn't considered it but I will keep it in mind.Have you considered semi-hydroponics with cymbidium?
Many years ago, I imported about 500 Chinese species a month from Taiwan. They arrived as bare-root divisions, consisting of two old growths and one new one in-spike. Dropped ‘em into S/H pots and rarely even lost a bud.
My recent experience with Grodan mini-cubes suggests that rock wool is another good option.
