Mini Vanda repotting advice and other recommendations

[avian]

I received 5 mini Vandas from Krull-Smith about 2 1/2 weeks ago. They are potted in plastic pots. 3 of them came with very little or no media in the pots and the other 2 are in pots filled with LECA. I have never grown anything in LECA so how often should those be watered? As per Krull Smith, I was told daily.

Can I place these outside? Temps range from as low as mid 30s in the winter and can go up to low 100s in the summer. Not a lot of humidity here in So. CA. Krull-Smith website states that they "will do great both outdoors or in an indoor setup." Have two other mini Vandas and those are sometimes outdoors depending on the weather. Have a mounted Neofinetia outdoors and one indoors. If I put the new minis outdoors I would probably bring them inside if weather became too hot or too cold.

I think it might be good to repot the ones that have no media. Would that be a good idea or should I attempt to mount them? Have never placed any of my orchids on mounts. If I repot should I go with LECA, bark mixture or sphagnum moss or nothing for the ones without media and perhaps put them in hanging cedar baskets? If I go with cedar baskets, can anyone recommend good resources from which to purchase those? Thought I could hang the minis on the branches of my lemon tree or under some shade cloth (40%). As for the ones with LECA, should I repot those or just leave them in the LECA for now?

Thanks in advance.
