How much longer??? pt2

Hey I dont have a microscope yet and I've never chopped before so Im counting on you guys to kinda help me out. These are 2 LR#2 been about 8-9 wks and Im thinkin Ima leave them another wk jus to be sure. How much longer do yall think??

Since you have no scope, all you have to go on is the color of the hairs. Rule of thumb is over 70% red then chop it. If it is hard to determine, just look at a sq. in. or so and see how many white hairs you see. Repeat that a few times, and you'll know for sure.
