Harvest & Curing Checking trichs

[Surfer Joe]

I have a lab microscope and enjoy looking at the buds and leaves on the growing plants and I noticed that the trichs on the back sides of leaves are much denser and better formed than those on the front sides.
Does it make any difference when checking on the trichs whether to look on the tops or the bottoms of leaves to determine their stage?

Not an expert here, but I try to observe trichomes from several places on the plant and take an average or percentage. Then I use that to decide when I want too harvest. I don't think I have noticed a real difference between top and bottom, mine have just been covered everywhere.
