I’ve been reading a lot of websites just to get a general idea of flushing and did see a few things about not flushing. Just curious
@Gentlemancorpse, how do you finish? Do you just let the medium dry up or just feed right to the bitter end?
I did have a really heavy bud Fall and crimp it’s branch, so I pulled that and am letting it hang dry. I guess, inadvertently I will be testing between flush and no flush!
Flushing is probably the single most contested practice in all of cannabis growing. FWIW, no commercial vegetable growers flush their product.
They feed through and through, and there is no negative impact on the produce. The plant will only uptake what the plant feels it needs at a given stage in life. The science simply says that flushing starves the plant of nutrients it might want at that given moment, thereby potentially having a negative impact on final product quality. If it's late flower, the plant's done with excess N, so it's not going to uptake it. What may happen if you try to force it is you lock out availability of other nutrients -- nothing more, nothing less. You can't force it to eat something it doesn't want.
That being said, you'll find cats all over that say they can tell the difference. That unflushed weed burns to a black/mixed ash versus white ash. That unflushed weed causes headaches or other issues. That unflushed weed tastes bad versus flushed weed.
My contention is there are mobile and non-mobile nutrients in the plant. Mobile nutrients move throughout the plant and never get locked in the cells. Non-mobile are uptaken by the cells and forever locked in -- no amount of flushing will purge those molecules from the plant's structure.
Now, that being said, if a bud burns to anything other than white ash, that indicates a few possibilities.
1: the drying/curing process was botched somehow. This is the most likely cause ime. Headaches/bad flavor/poor burn/etc all lead to this.
2: the grower fed too heavily on non-mobile nutrients earlier in the plants life. This is likely a result of the PK boost formulas that are now being proven to be ineffective, and frankly a waste of money.
3: the plant's genetics simply produce that kind of burn, with more carbon-dense characteristics.
For sake of avoiding an all out brawl over this very touchy topic, I'll leave it up to you to make your own determination. I choose to believe people that feed countries over hippies growing in a spare room and smoking entirely too much pot. Just saying, in the most respectful and non-derogatory way possible.
