Ok, not to get of track of the above threads but I do have an age old question about flushing, this is more of an experiment in the technique of flushing, I suppose.

Many years ago, an old MJ grower told me to flush for 5-7 days, like most of us do with RO water, maybe some clearex, I use flawless finish myself from AN. After that flush, put those pots into another pot, no holes, and flood with straight RO water. In essence, you will be drowning the root system for another 5-7 days then harvest.

The old man noted, when you drown the roots for another 5-7 days, it makes for a better, cleaner smoke.... Or he's blowing smoke up my arse!!.

I myself grow pretty simple. Easy seems to always win, I tried most of the snake oil out their and get some weird plants in the end,,. So I keep it simple with nutes, no more shit I can't pronounce and just stick with the basics. With that said, I grow in coco and soil so I do like to flush. DWC, I love just not enough room.

Anyways, would soaking, drowning, the root system do ANYTHING better for our autos?.. More heft, size, cleaner smoke???..

I decided to finish off 5 girls off this way a few weeks ago. The interesting part is, during the drowning phase of flushing, the girls did put more weight on for sure!!.. I had branches of buds bent over when they were upright a few days prior. The fan leaves, what fan leaves I had left, turned all yellow or orange. Now, they did put on a lot more weight and did swell a bit more during this phase. Is it because they just absorbed more water?.. Prior to this, I flushed twice a day running RO with flawless finish for close to 7 days. The water towards the end of that flush was pretty clean.

I read an artical published by a university studying the effects plants go through when the roots are submerged in water for long periods of time. Wish I could find that artical again!!. This is what I remembered;...



Fermentation is strictly defined as any way of anaerobically degrade pyruvic acid and recycle NAD+ to keep glycolysis going. You can then categorize this process as lactic acid fermentation (where pyruvate accepts electrons from NADH directly and becomes lactate), alcoholic fermentation (where pyruvate is first decarboxylated to acetaldehyde which then accepts electrons from NADH to become ethanol) and others (which are much more obscure). So technically, human cells are able to carry out lactic acid fermentation. Liver cells also have the enzyme alcohol dehydrogenase (responsible for ethanol formation in yeast and other fungi), but we use it in the reverse direction so to speak to get rid of any alcohol which we consume by converting it to pyruvate.
Plants however, can carry out alcoholic fermatation. They don't normally do it, because plants are usually in contact with oxygen. However, if you flood the root of a plant for about a week the cells are starved of oxygen, and because of this they will start carrying out alcoholic fermentation to survive.

So, dose this drowning of roots start the fermentation/curing process prior to the actual harvest?.. Dose it provide a slower, more stable cure when it's actually curing?.... @Corgy, any ideas?..

I'm still in the process of curing so I have no reports yet from the ones I pulled down a few weeks ago..

BS myth or some truth?.. Thoughts are always welcomed!!. :cheers:

It's plausible. Alcoholic fermentation is precisely what happens when fruits are kept under controlled atmosphere, i.e. low oxygen and elevated/high CO2, to prolong shelflife, and the O2 level gets too low. The fruits starts to convert sugars into alcohol, as you describe in ermmmm....layman's terms above.
When the fruits are removed from the controlled atmosphere, the alcohol quickly dissipated as it is converted back again to sugars when normal respiration resume in a normal ambient atmosphere.
Some fruits, say New Zealand apples, are kept in controlled atmosphere more than once during the stages of the voyage from tree to a consumer in say Europe, where it will arrive perhaps 6 months or more after harvest.

Whether these processes play a role in the curing of cannabis buds, or more correctly, the fruits..........again, it's plausible, but without expensive controlled research under lab-like conditions with a large number of plants involved including controls......who really knows, and since it's mostly organoleptic in nature there will probably be a large element of individual preference!

Interesting the swelling/weight increase you mention, question is of course as you allude to is this mainly just water that will evaporate again during drying, or is there a worthwhile percentage of "dry matter" too that will remain?
It's something to keep in mind and I might try this with a couple of the Fantasmo Express run I have going, there only 5 plants so it won't be much of a true reference, but at least it'll be fun and something new to fiddle around with if nothing else. Still some 5-6 weeks to go before any drowning coming up though!

Interesting subject, and it spills over to the respiration of cannabis fruits, ethylene sensitivity/production, climacteric or non-climacteric and such.....

Well, I knew you would be the one to dispel or concurs this idea @Corgy!!. Lmao, I love my, erhemmmmm, laymen terms, as I so called it or what other may call insane!..

I highly doubt any weight gain will be anything but, dissolvable water or swollen cells I don't really weigh my buds, just my personal use so not much care about that part.

I suppose the idea is to, make the cure 'faster' by doing this. Personally, I'm in no rush. I have a stockpile for years and not in any rush to hurry a cure. But, it's an interesting idea none the less. I like my smoke to be smooth and enjoyable for everyone, that was my goal with this idea.. Not trying to increase yield, only a awesome smoke.

I also thought alcohol will convert to ethanol as a byproduct instead of simple sugars?.. Or was it ethylene as it dose not evaporate as quickly as alcohol?.. Hum.... Damn science can be tricky. I need to get back into agronomy science to remember all these ideas!!..
 
Stunting autos early to prolong veg to be able to train..(2 weeks or 3 nodes-whichever comes first)......The NL auto triplets....day 87 in their lives...left-topped....middle-fimmed....right-untouched.........fim/top now in PF....untouched-flowering..............non-optimal conditions-outdoor Bay Area-winter..........extends my growing time up to weeks to month plus....but i do rotation=free sun-grow year round ==done others....more yield and more uniform buds with less popcorns
