Katrina-Yes, its the growth opposite of the spike.
I would think that a root might not be stalling for so long and the shape of the growth does not look like a root much because it actually has a node forming, which I'm not sure if u can see it clearly in the picture.
The only thing that I'm not confident about is the light my orchids are getting, but my one and only oncidium seems to be putting out new growths like crazy...Then again, it might be just putting out new growths but when it comes to flowering, I'll just take my chances.
Thanks for the replies guys...I'll stick to the 'insufficient light' yheory
