Ooh I'm sorry, didn't realize, must have missed it somewhere
Chunky peatmoss isn't ready available. I use the farfard brand, african voilet mix- its pretty good
Sure peatmoss is acid lower 6.2 ph levels - orchids love it. You can combind charcoal to help steady the PH balance. As the peat ages it will become less acid over time. I do add some bark and perlite.
I grow catts, dens, phals, paphs, phrags and others in this mix. I've been using this since I got into orchids, didn't know I wasn't supposed too and got called a mud grower
Fine with me, orchids thrive for me using peatmoss.
Repotting can be once per year or every 3rd year, it depends on the growth - its a freekin' breeze with peat
I use ferts 1/2 strengh every second week 7-5-6, I believe.
With any new mix, go slow, learn it before you put the collection into it.
