I suppose this is kommon knowledge, but...
You don't need to check your trichs through a 30X microscope. You take your digital camera and shove it as close to the bud as you can (my Ricoh R1 have a great macro function - for a compact - and can take a pic as close as 1cm), take some pics from different angles, then check them at ease on your broadscreen. Beats trying to focus on snips under the microscope. Best way to survey a spidermite infestation too.
Not that it's necessary with these DJ Short Blueberry buds, they're only on day 37 in flower. Still a long way to go. No Spidermites either.
Notice the little fly stuck on the trichs, on the right side? I get a whole lot of these critters that stick to the trichs. I don't have Spidermites anymore, killed the Fungus Gnats, spared from thrips, so the Dark Lord of Nature sent me these obnoxious flies, which I suppose I'll be smoking well-done.
