Looks like a real good job, especially for first grow. Not sure if my sense of depth is off due to photo, but one thing to watch out for could be the outer colas leaning when they get heavy and pressing against the tent. I’ve had this happen and they get misshapen and not as much light. I could also see it contributing to bud rot or other issues, so it may help to use a trellis.
With all due respect, I disagree. Better off counting from when the plant starts showing signs of flowering. That said, five weeks may not be an unreasonable estimate.
I second that.
