Hello, this is literally my first post here, so
I just bought this very cute Brassavola nodosa 'Panama Soire'. It's still somewhere in the post so no pictures for now.
Have no experience with Cattleya or its subspecies/hybrids/whatevers, I've been researching ahead of her arrival. The grower I bought from told me the Brassavola would arrive potted in bark. Now I'm trying to decide which medium to repot her in once she's settled in and growing new roots (which I assume would be the ideal time to repot Cattleya and its subspecies/hybrids/whatevers).
I'd
like to repot into S/H culture, mostly because I happen to have unused leca on hand (and no bark). What experience I have with leca/semihydro is gotten from sprouting and growing grocery store fruit seeds in leca/semihydro. Some of them are still alive, more than half a year later. So I'm not completely inexperienced with this culture.
My reservations with S/H are,
1) The leca I have on hand is on the large side, with diameters around 0.4 to 0.6 inches. I think the large size and extra space between pellets might cause problems with very fine rooted plants, because the fruit seedling grown in a mixture of leca and crushed lava rocks does better than the one in pure leca. I don't know how large the Brassavola roots are and how (or whether) the extra space between pellets might affect her roots.
2) I read that Brassavola nodosa are warm-growing epiphytic orchids. With S/H culture, she'll get 'cold feet'. And I'm not sure how well she'll like it.
3) I also read that Brassavola nodosa prefer drying out between waterings. With S/H culture, I can't provide that 'dry period' unless I let the reservoir dry out completely before watering again. But isn't it bad for roots to be exposed to bone dry leca?
After S/H, the obvious next choice would be bark as medium. I suppose transition would be shorter since I would be replacing bark with bark. With a phal potted in bark, I also have experience watering this medium. The downsides would be, well... buying it.
And a question about Brassavola nodosa light requirement. They're said to be bright-light loving orchids, living outside in many places. Mine is going to be grown indoors in front of a south facing window. In winter, that window gets full sun when sun deigns to show. But in summer, she's not going to get any sun whatsoever. Is the light enough for her to grow and flower?
Please advise.
