Pot sizes for regular potting using LECA

[bogdan]

Hello
I read that bigger pots can be used for s/h potted orchids, due to the nature of the particles that wick moisture uniformly.
My question is, would this apply to using LECA instead of bark in regular pots, or that would keep humidity longer, thus rotting the roots (of Cattleya alliance plants in this case)?

I did pot some plants directly in 6" pots from being overgrown in 3" pots and used Hydroton (I imagine this would be a no-no-no with bark). I did not plan to use s/h on these, as I wanted to see if they can grow without a reservoir as well, and to see how fast they would dry. If the need arrises, I may put a bigger saucer under them and call it a reservoir.

Thank you!
