It's such a pain in the butt for me to look at triches; I would probably need some really expensive camera equipment to be able to do it better. Using the little hand held microscopes is always so frustrating to me, BUT I can catch glimpses on the plant itself. That's why I like the one that connects to my computer, cuz I can snip a sample and put it down, and it holds still; all I have to do is focus the scope.
The buds will be lighter green and round, and covered with triches. You will get to see the difference between them and the leaves the more you look. Your cell lens should work great for that.
