Gee beadip, sucks that a chair fell on your plant. If I was you I'd just cut it back (rootball and all) and repot it rather than start it from scratch again.
Both my Naga's are doing good right now. I cut one of them back and replanted it into a smaller pot and it just took off! If it survives, it's gonna be a big producer. There's already a ton of flowers on it and I only have it under 4' floro's at the moment. The other one is too big to fit under the current grow setup, but it still seems to be doing fine with limited winter light in the window.
Still battling aphids. Miss one and they're back in full force within a week.
