Has anyone ever tried flushing their plants by keeping the root system intact when harvesting and then keeping the roots saturated while the plant hangs upside down for its dry? So many arguments for or against flushing during a grow and I suspect this could be a nice compromise. You get to feed your plant until the very end and then still be able to flush it during the hang. At the very least I figure it would extend the hang dry process allowing for more dense buds, but also will increase the risk of mold.

Just smoked and now I am coming up with some bro science . Maybe someone with more experience can let me know if this is even plausible. I've heard of people doing other things like hooking an IV up to the plants during the hang and pumping whatever nonsense they can think of into it.

So you are drying out a plant for consumption in a dark tent and you want to continue giving water to the roots?

Really just say that out loud a few times and see how silly it sounds.

Flushing is appropriate for a very limited type of grower. Someone who runs the ragged edge in coco with CO2 could prolly benefit from a reduced nutrition load at the end of grow.
An organic soil grow has no need for a flush.
DWC properly maintained with proper nutrition levels there is no reason. A plant in lockout due to salt nutes could benefit from a flush.
Blind taste tests show no preference and the rest wise just bro science.

With roots still intact, with air, the plants keep growing. Till the circulatory system drys out. Longer hang time.

It does sound extremely contradictory, but so do some other popular growing techniques we know that work. Imagine the first person to ever top a plant. Every other grower in the world probably thought they were crazy. Every growing technique once started out as bro science until someone decided to give it some true research.

That being said, I do agree with you on every point. I run DWC and personally have never flushed.

I did see one study on flushing that showed most testers preferred a 0 day flush over a 7, 10, or 14 day flush. Odd thing was that the preferred order, in nearly every subjective category (taste, smoothness, etc.), was 0, 14, 10, 7. So, it basically indicated that if you are going to flush, longer is better, but not flushing is still best.


This is what I would expect to happen. It would continue to drink until it dies from lack of light. It would still slowly dry out while drinking since the plant would perspire all that water plus extra. Longer hang times (slower cure) is something that has research behind it and is crucial for preserving trichomes.


I may give this a test when my current grow is harvested. I also want to test ethylene during the last few weeks of flowering and through hang dry. I read it can be absorbed through roots, same as leaves, so during hang dry I can test one plant with a bag of water strapped to its root system and another plant with a bag of banana peels. Ethylene is known for its ripening properties and ability to break down chlorophyll. I have seen studies of using it during germination (supposedly gives greater chance for feminized plant) and flowering (supposedly increases trichome production).

Yeah but that same “experiment” was ran by a nutrient company ha ha ha.

So of course the zero day was preferred!

Sadly, this is the only company to put out a “study” on the effects of taste and flushing.
