Sphag n' bag - need some help :)

[wasillisaw]

Hi guys, this is my second thread on this site.

I have a question about "sphag n' bag" re-rooting technique.

Some time ago I overwatered my ochid so much, that it lost all it's roots and most of the leaves. I've stepped upon using shpagnum moss and a bag, to propagate new root growths, and guess what - I now have two baby roots.
But I have a little concern. They seem to have stopped growing and now they're just chilling with the orchid in the bag. I really don't know if im doing anything wrong, because it's my first time using this remedy.

I mist the sphag. with water everytime it's getting dry, and the bag isn't sealed completely so the air can go inside. I try to let it breathe so there's no mold or fungus growing. Once every 2-3 weeks I spray the moss with fertilizer, that is higher in phoshoprus, because I've read that it'll stimulate the rooth growth.

Also, when do I plant it in a pot? Do the roots need to be specific size? I'm just scared it's gonna stay in that bag forever because I'd be scared to destroy it

Am I doing anything wrong? Please help me
