Pick a calyx and snip it w/ scissors. I had a picture of one in Amnesia Haze bud & trichs 
. The one in the picture is a little larger than I try for. I posted this picture in the blueberry auto thread 
. I replaced the flex stand with this aluminum one. Between the height adjustment and focus you can zero in fairly well. Basic limitation is depth of field with the higher magnifications.
That is the tough part. If I can, I will just cut what is ready and let the rest of it go a couple more days, maybe more. A lot of the smaller buds from the bottom end up in the freezer. I have an excess inventory problem. I was planning on doing bubble hash and some extracts with it but have not gotten that far yet. Some of it I just cure and dry sieve it to make pucks with a t-handle press.
Heading back to the garden. Planted the onion sets this morning. Now garden peas and snow peas.
I’ll plant peas 2 different times to extend the harvest period.
