All finally decided to show sex:
3 Females
1 Male (the ex-runt, has 11-finger leaves)
1 Hermi (yes, sloth is a he-she for sure)

The final verdict is 1 more month of veg. I know we're going to be having hellacious space issues with the massive difference in size between the old plants and the rhinos, but I don't care. We'll end up with 3 fucking giant trees and however many of those rhinos decide to be female. We went ahead and FIM'ed every single one of the tops on sloth and topped the original girl. The one I topped orginially is still fine, and I tied down the blueberry one some more. The one that I've tied down a lot is taking shape so nicely. I can't even picture what our room is gonna look like in a month......I might end up being able to build a tree house in one of these.
