After struggling with the cheap hand held devices I paid up for the digital usb that puts the trichomes on the computer screen. I thought I was on top until I went to a person's house for xmas and they had a lab type microscope. I used it to check some buds and it was like driving a caddillac. So much easier and clearer. I was so impressed I bought one and it's in the mail. I may have screwed up though because I bought a compound microscope not stereo. I don't know what kind the person had that I tried. Can you even look at buds with a compound microscope or do you have to put them on a slide?
