Hello, repotting and S/H attempts in Idaho

[kkdcalgary]

Hi Orchidboard! I just moved from Hawai'i to Boise Idaho and I managed to bring a bunch of orchids with me (thank you kawamoto orchids for so graciously helping me ship!)

The orchids I currently have are:
# large Blc. Lawless Walkiire "The Ultimate"
# Maxillaria tenuifolia (4N)
# small Brs. Rex "Waiomao spotless"
# large Bc. maikai "mayumi"
# Den. aggregatum
# new small hwra. lava burst "puanini"
# new small Onc. twinkle "red fire"
# Epc Renee Marques "Tyler:"
# Epy. Serena Oneill (whew that's more than i thought i had)

The 'puanani' and 'red fire' I just bought while they finished flowering from a local nursery and the water drained brown when I first watered them. The lava burst 'puanani' (first pic) initially had some small root growth that slowed and the green root tips are now gone. I repotted it in hydroton and sphagnum since the root growth slowed. I was planning to do this quasi-semi-hydrotonically with a half inch of water each week which I assume will dry quickly in the boise climate.

The 'red fire' ended up being two separate plants (second pic), I've only had time to clean the roots and have it sitting in a wad of sphagnum, the left one has two happy new roots, the right, nothing. I was also planning to repot this into hydroton for S/H culture in a starbucks cup with holes in it.

The next two pics are of two coconut 4N orchids that I have potted together in hydroton. I repotted before there was root growth this year, which I'm not sure was wise, but it's been very hard keeping up with the moisture needs in boise and it's now in a S/H setup. The third is very shrivelled and sad, I have it sitting in a big bowl with the 'red fire' while I figure out what to do.. I sphag and bagged it but the roots kept growing mold, does that mean they're all no good??

The last, happily, is my first rebloom of a beautiful magenta cattleya called 'The Ultimate' - the ones at the nursery in hawai'i had multiple flowers on new growths, but I was pretty happy that it enjoyed the move.

My other orchids are doing ok-ish some better than others, but all have had new roots and new growths since I moved last fall luckily. The more I grow them the more I think it's not messing with them and dumb luck! I think the orchids are actually happier here because they were overly wet in honolulu and had poorer sun exposure. I'm also very type A and have to resist constantly repotting because I don't like how the roots are doing....

Any comments or advice on any of the above super welcome thanks for reading!
