Week 4:
She's trucking along. Not my fastest grower, but she puts out bushy little side shoots at every node.
I'd say she's going along at a perfect slow veg, and I expect explosive outdoor growth.
I did have to raise the light fixture today for some of my bigger plants, so she may stretch a bit, but her stem is thick so I think it will just help contribute to the eventual goal of her being 10ft tall.
