You’re off to a great start! Taking pics and collecting data is a priceless tool to help you improve year to year. As far as knowing when to harvest..... If you want to be specific about it get a 60x magnifier lens from amazon. It’s great for identifying pests too. Once they start getting frosty, producing resin, the smells in the field really take over. They’re also sticky to touch. Keep an eye on your trichomes those are the glandular heads where the phytochemicals are biosynthesized. They will go from clear to cloudy, to a light gold (or Amber) to a darker and darker amber. You want to harvest when those heads are between cloudy and light gold. Any later means some of your phytochemicals have degraded. If you have farm equipment for tobacco use it to transport harvested material from the field for drying. You want to hang in a very well ventilated area. Optimal would be 60 degrees faranheit, 60 percent humidity. You’re aiming for anywhere between 8-12% moisture before processing or rolling depending on what products your going for. Most 3rd party do moisture content tests for $30. There is also a blog post on the IndustrialHempUSA.net website with resources that may help, has tons of scientifically supported links. Also, would love to meet you at the Southern Hemp Expo this next week, I’ll be around for further discussion. I’m also talking about just this at the women in Ag summit next Thursday and at the Sept 12th extension meeting in Jackson. Hope to see you around!!
