Since this thread started 5 yrs ago, almost to the day, I personally felt compelled to bump it or rekindle it. Especially since reading thru 27 plus pages visiting various linqz associated with the topic of "flushing".
Alright now, here is where I'll start. I consider myself to be a muthafkn GURU, a damn gro monsta, started off in hydro, dwc, soil mix, Coco mix, you name it I grew it ! Tons of strains and tons of Harvey's. Made some mistakes, rectified said mistakes. Met some marvelous people with loads of knowledge and willing to share some of the knowledge, met a bunch of a holes steering a MF in the wrong direction, which taught me to be diligent in my research. Also I read my bitches ( plants )
I know what they want n need ! But hell I'm still picking up pieces of this complex plant.
Now a far as flushing is concerned, that shit should happen throughout your grow, hell who doesn't like a refreshing drink a water, it should be done weekly followed by a light feeding . As for the finish, I prefer to use the term "final rinse" . Everyone should know by now to ramp your feedings down to a minimum towards the finish line. If done properly, that final rinse shouldn't take longer than 3 days. Think about it, after that final swell of them drippy resinous buds throw some of that plain old refreshing water. IMHO that'll take away the option of the roots to take in one last meal up to your finished product.
And to end this long ass diatribe, I'll mention drying and curing. As a must, drying should be done in the slowest manner possible, to me very important. You have to let the chemical process break it on down by itself, don't try n rush this process. Once the buds snap off of the main stem, clean it and begin next process after a sample of course ! Now if dried proper like, you should be able to enjoy a little. But not to much, put them shits in a mason jar almost packed but not stuffed. Give it a day or 2, and remove the buds inspect them shits, squeeze a little, smell em, if everything is how you put them in originally, put them back in the jar. Repeat this process for 2-3 more days, sample again, everything all good, put jars in a dark cool environment and forget about them for a few weeks, occasionally check on them. Once you get back to them you won't regret it, the flavor will have kicked in, and some of that sweetness. A little extra time and you'll never Eva purchase dispensary or black market bullshit again. Enjoy that finish product, roll up a fat jizzle and let that sizzle! And if you did this rite as your rollin up with fiskars in hand you should have some Stkyfingaz like ya boy !
