Neostylis Lou Sneary Seedling Culture

[ozymand1as]

I bought a hardened seedling of the above orchid and am looking for culture advice. How does raising falcata seedlings differ from the mature plant I already own?

I want to try this one in semi hydro but am unsure whether to repot right away or wait for spring. This one is currently in bark, which frankly does not work well under my growing conditions. Most of my plants are in pure sphag or S/H.

Also, what about feeding or lack thereof during winter? Does this aspect differ when the plant is still so immature?

Thank you for the help.
