I actually harvest twice. So i leave all the main tops from each plant sticking up through the trellis and i leave the "shoulders" just under the trellis and then i clear out everything else underneath the shoulders. SO... i watch as the hairs start to turn orange i know its time to start watching the trichomes. When all the trichs are fully milky white through and through (there will be just a few trichome heads that will have turned amber). Personally i prefer to have a few amber trichs to ensure ALL the rest have peak cannabinoid levels. You may prefer the "couch-lock" and might want all the trichs to be amber. Either way, once all of my mainlined colas are ready, i cut them all down. Then lower the light a few inches and let the "shoulders" (all the buds that are at or just under the trellis) and giving them the extra light for an extra 2 weeks (between 1-2 weeks, watch the trichs) gives me a second harvest. Personally, this second harvest is AMAZING for extracts. I specialize in solventless extracts, like rosin, blonde hash, live rosin, infused oils, ect.. and many other people here do solvent based, like shatter, distillates, ect... (not my area) but fwiw, if interested in going the BHO/solvent based route, i believe using hexane pulls out more
terpenes than butane. Wow sorry, really going off topic this time...... focus J...
...right harvest, thats where i was
so doing it the way i just described, sometimes the second harvest ends up weighing the same as the first. And sugary as fuck
