I sorted through your previous photos again.
Again, let me tip my hat to you for such amazing results without the years of experience. It seriously looks like you've been at this for a very long time.
I certainly hope you have at least one to two competent people to help you on harvest day. The number of big, dense colas I count in your pulled-back shots are amazing... but I wouldn't want to be the one to trim all that bud.
I see that your mature buds look pretty comparable to mine in size/density. Be very careful not to jar or bag them before they're dry enough. With buds that dense, you don't need to freak out about them drying out too much... but you do need to freak out if you sweat too early and your buds end up smelling/tasting grassy. Those things are loaded with resin...and resin hardens...doesn't dry. Give it at least a week in hang before bagging or jarring.
Edit:
I say this because it's extra important to allow those last traces of chlorophyll to dry out before allowing them to sweat. Improperly harvested bud tastes and smells grassy because those last traces of chlorophyll weren't handled properly. People smell their grow under the blazing lights and just think dank, dank, dank... and are shocked and disappointed when they harvest and it turns out not smelling dank, dank, dank, but grassy, grassy, grassy.
When you shut down your grow and turn the lights out, your nose detects just how much stored chlorophyll is still in your plants... there is still quite a bit. You'll notice that during the first few days of drying, if you sniff your drying buds, they'll smell grassy. That's natural and it's because it's releasing the chlorophyll that evaporates initially. Remember, chlorophyll, the green in the plant that tastes and smells grassy dries... that's what you're really drying during dry week. The resin doesn't dry and evaporate, it solidifies and hardens. After the chlorophyll has left, the resin is all that remains...and that's what tastes and smells dank. Put them in a jar or bag before all the chlorophyll has evaporated, and guess what? that's right. Having nowhere to evaporate, the grassy chlorophyll sweats through your entire crop. You don't want that.
Edit again:
All of the above applies especially to high-wattage light growers like you (and me). You can't expect to treat your crop the same as someone growing with a smaller light source. With over 3000 watts blazing down on your plants, they have been photosynthesizing at an accelerated rate compared to a plant growing in a more conventional, less intense setup. That means you have to take special care to prevent grassiness at harvest... or you can bag them up after only three days like someone else suggested and see what happens.
Edit again:
Oh, and during dry week, dark, dark, darkness, and slow, slow dry with gentle, and I mean GENTLE air movement not directly on them. Once dry, they'll feel crispy on the outside and the nugs should snap easily off the stem without the use of a scissor. I've read on the internet to let it dry until your main stalks snap. This is limited instruction as that information would only apply to a real twiggy little plant. Real plants that have huge main stalks... to let those dry until they snap would take weeks and be ill-advised. Just make sure it's dry enough that the little stem connecting the buds to the main stem snap... Don't worry if some of your thicker main branches are still a little bendy (we're harvesting bud, not branches).
Then and only then will you jar them. They feel crispy and the buds snap off, but don't be fooled by that. There's still trace moisture at their core. So now that all the green chlorophyll has evaporated, you can now sweat out that tiny, tiny bit of moisture at their core slowly... This is the cure. Continue to store the jars in darkness and open them once a day for about 20 min to an hour to let them breathe.
**of course everything I've been saying applies more importantly to your premium upper nugs. The lower fluff nugs you can play around with... But don't fuck with the premium tops.
So that is my advice for drying and curing. As for the finish in terms of flush, I'll have to refer you to my colleague, dsmoke1, as I am only knowledgeable in hydro.
