Just an update- It's a FEMALE! And she's gotten so big. At least a yard high and a yard wide, and there're like 4 colas on top (aside from the main one I guess?) which just grew there of their own accord. She is drinking about 3 liters from the 6 gallon res every day; the root mass has taken up half of the res.
I am having to raise the light every two days, and am starting to wonder how I'll do the water changes if she gets any bigger. That, however, is a good problem to have though I think. I am stoked but not over-confident, as I am just a newb still. She's in her 12 hrs of dark right now, but I'll post pics of the whole thing later.
Thank you again for all the help and info in this forum.
