Awsome Lienluu.
I have a couple of seedlings that I bought from Sheerwood a few years ago. They are just now thinking of adding new growths. They did poorly in potting mix I used for most of my multis (with oyster shell), but do much better in my no-calcium mix with sphagnum moss and some volcanic rock. They are closest to the humidifier and stay cool and not too bright.
They have been slow growers for me, so what's your experience?
