I don't have any dates on these but the first was around December of last year, most recent was a few months ago, now the rock is empty because my b/f refused to believe they would roast under the new halides and I let him learn a hard lesson, gotta refrag for him one of these days.
At it's glory it was totally covered and growing on the back, good thing these are fast growers. Next time I'll keep dates better.
