Hi all,the way i do it is check all the calyx that u can see and that are swollen (hopefully all)on all the buds,that seems to be where most of the trich development is,also u can look over the bud leaves but the calyx has the most.
Can you describe from his pictures what the calyxes are? Looking at his second pic, the one up close, which part of that is the calyx? I would think it's the tiny green leaves that the hairs lay on and form the mass of the buds. Is that right?
As far as harvesting goes, my observations from reading is that you want a strain's trichs to at least be cloudy, if not some amber. It seems like cloudy with some amber would be the point you get the truest characteristics of what the breeder would have described about the high. If I used your method and didn't want a couch lock and found one plant to be mostly or all cloudy with a few amber top to bottom, I'd harvest the entire thing. Knowing bottom branches tend to mature faster, if the bottom branches were ready but the top branches still had a lot of clear trichs I'd only harvest the branches that were ready and wait a little while on the others. I would also wait on the plant that still had a lot of clear trichs. I'd at least want them to be mostly cloudy. The thing is, they look so ready to me(my inexperienced eye). It would be hard to leave them out there to mature much longer just because they look so ripe. From watching the Greenhouse videos I remember their white widow or white rhino looking ready about ready but their saying you could wait a little longer before 8-9 weeks and it will really get snow covered with trichs. These plants are at 7 weeks and both nirvana and greenhouse say their WW is 8-9 weeks. Still, I guess you have to go by your plant and what it's showing you under the microscope and how much of the CBD couchlocky high you're willing to tolerate. It doesn't seem like you would want to harvest any branches that have clear trichs and in order to produce the THC have to wait til they are at least cloudy. If I get my plants to a point where I have a choice I will probably harvest some branches at all cloudy and some at cloudy with some amber if I can discern that under the microscope just to see if there's that much difference. But I seriously doubt I'll wait til most are amber(not that anyone suggested that).
I wonder what a sativa with mostly amber trichs would feel like? All these discussions about trich color determining the high makes me wonder if you can harvest an indica with mostly cloudy that seems just like sativa or sativa with mostly amber that seems like indica.
