Njanneanswered grow question 5 years ago You can order a cute little digital microscope from Amazon for around $100 and it will allow you to zoom right in on the trichomes.
This is the one I have : https://www.amazon.ca/Celestron-Handheld-Digital-Microscope-Pro/dp/B00CMJ1I08/ref=sr_1_3?crid=TNDA6PBQNQ69&keywords=celestron+digital+microscope&qid=1562203808&s=electronics&sprefix=celestron+digital+mi%2Celectronics%2C154&sr=1-3
It really is the best way.
Otherwise, six weeks of flowering should about to the trick for this variety :)
