Flushing Before Harvest

In hydro i do last 3/4 weeks depending on how they look, in soil i do last 2 weeks just water, you can get stuff called fast finish, but the stuff i really like and have used for years is stuff called 13/14 am sure its by canna its a final boost--a little last push for her you are only meant to use it once 3/4 weeks before harvest, its very good stuff ok a little expensive for 1 ltr but it does work, if you can find it online buy it, i get mine from growell and it goes along way 10ml per 10 ltr.
also just before harvest i like and prefer the soil to be almost totaly dry. but 13/14 have a look for it.

anyone know anything about flushing reservoirs such as an aerogarden? i figured just empty the tank and refill with distilled water and let the plants drink that until theyre ready to trim. i will be using gen. hydro's floragrow and florabloom. anyone know about the strength of these in regards to flushing time? thanks?

I sampled my baby 2 days ago, I didn't taste anything unbearable....but I am doing a 2 week water flush every 2.5 days, until I harvest. I will let everybody know how they taste after curing for a week or 2.

I've noticed a difference with my first grow...

The first plant I flushed once 2 weeks prior to harvest - smells like nice bud...

2nd plant I flushed a couple days before I pulled it (2-3 x the usual watering amount) and it smells and tastes completely different - I reckon the smell is chlorophyl, but they were both dried and cured for the same amount of time...definately smells more like chemicals anyway...so I learnt on my first grow to flush once 2 weeks before harvest, thats what I'm doing this time round as well...although hopefully with bigger buds!

flushing is very important. if you dont think so your either just a pot fiend or a lazy basterd

You do know this thread's like three(3) years old, right? Anyway, I'll chime back in. I NEVER flush. !IN MY OPINION!...it's a myth and a waste of time. For all the people out there that think it's necessary, I'll ask you this. If any of you have a garden, do you flush your tomato plants before you pick them? Pretty sure you just pull them off as they ripen, wash em' and eat em'. Now don't start getting all stupid and say, "We're talking about marijuana, not tomatoes". It's the same principle. You don't taste chemicals in your veggies, and you don't in your buds. Plants uptake nutrients and change them into sugars and whatever else they need to grow. Those chemicals are not delivered to the flowers in the form in which they were when they were mixed in your watering can. Like I have posted before, almost all Marijuana plants do most of there "Fattening Up" in the last two weeks. And it just makes sense to me that the plant is gonna need nutrients to do that, just like it needs nutients to grow lots of nice fan leaves during veg. When your old lady starts putting a few pounds on, it's not because she's dieting is it? No, it's because she's eatin' Bon-Bons. So feed em', dry em' CORRECTLY, and CURE, CURE, CURE!!!! If you cure them correctly and long enough, you will always have great tasting, smooth smoking, awesome smelling weed. Like I said, I never flush and ALL of my friends say my shit is the nicest they have ever had. Never had anyone say, "Man, this is harsh, or this tastes funny." Don't take my word for it people. Do some experimenting yourselves. That's the ONLY way you're gonna learn. A week before harvest, cut a nice branch off BEFORE flushing. Dry it and cure it, then test it up against the rest of the plant that you flushed. Simple! I'll bet ya dimes to dollars you don't see ANY difference. Do the test and come back with your results. I'll be waiting.

ya, there are a lot of unproven paradigms present in the online growing community. Flushing is one of them....

Ok...I know this is an old thread.....so I am gonna do it some good and test a few plants. I have 10 to harvest over the next couple weeks all different strains. I am gonna take some bud from a few plants before flushing and cure them up for 2 months in jars then me and a few 30 year plus smokers will sit and compare one weekend...(sounds like fun huh). I just wanna know...its my first grow so inquireing minds need to know.

My first grow I had a branch break off the day I changed my rez to flush. Naturally, I dried that single bud and cured it. It cured over a month like the other buds, only difference was coming down 5 days early and drying/curing a few days sooner.

The bud that came down early tasted salty, sent sparks up when burning it, and had a fairly unpleasant after taste. All of the flushed buds were 100% more pleasant to smoke and had a way better taste.

I say those who grow with chem ferts and dont flush either have shitty palates, or think the salty taste is what make buds taste "good".

Why risk your health, or anyone else's for that matter?

Exactly, when should u harvevst your plant, I've heard that u should harvest when the trichromes have turned half amber half cloudy. Does this mean that u should start flushing your plants now or does it mean that it is too late. i mean, I get so confused when i watch videos and they say that u should harvest now but, then it says that u should flush your plants with just water for two weeks do how will u knw exactly when to start flushing and when to actually cut the plant down and start trimming?

Hi, I am on my second harvest and I found flushing the plants to be very important as the plant has time to absorb the nutrients and produce last buds (those are head high buds cause the trichomes wont have the time to mature so it adds some head buzz to a body high harvest) and also because if you´re testing your weed to see what kind of effect do u want (transparent trichomes are good for head high and red trichomes for body high) you don´t want any nuts on it cause it will give u the worst head pain u´ll ever experience instead of a good idea of what your final harvest will taste and the effects it will produce.
If you´re patient and let your buds dry and cure properly this should´t be an issue but if you re quick drying some, toping for testing or just want to smoke some of your growth and cant wait to proper dry and cure all of it flush is the way to go.
Flushing a couple of times one week before harvest should be enough or even stop the nuts and feed the plants with just normal water two weeks before harvesting without flushing is also a good way to go, just keep in mind flushing to much is no good for the plants and not flushing at all mixed with quick drying or improper curing will knock your head off (in a bad way XD).
Timing is also important, if you want a head high ( higher concentration of transparent trichomes/hairs) you should stop nutrients as soon as u notice red trichomes on your plant and harvest a couple of weeks later when around 20% of the trichomes of older buds are red.
Or if you want a more narcotic body high effect you should wait for around 50% of the trichomes have turned red to stop the nuts that way when u harvest a couple of weeks later you ll have around 70% of red trichomes and a pretty good head high from your buds.
In the end its all a matter of personal taste so test the buds to see which effect pleases u the most and at which point you prefer the taste, just remember, dont go stressing to much your plant by over watering and flushing in excess as u wont go crazy with ferts in the last days before the harvest.
Cheers and have a wonderful smoke!!!

Got a quick question about flushing.

What if i cant flush, my plants are to big to getout of grow room let alone bring to the bath tube to flush. I quit using all nutes at the start of week 5 and am now going into the end of week six. I plain to continue to use only plain water till week 8 at harvest time. Do you think my smoke will be harsh and nasty tasteing.

i start flushng a week before i cut...i use mollases and water to water everynight for about four nights....on the 5th night i give straight water until the leach comes out clean and clear.....then let it sit for 2 more days and harvest the next morning........

what ratio of water to molasses do you use?

No need to flush chemical or organic. You flush a toliet, not a plant. Why starve them in the last few weeks when they put on the most bulk and resin?

This is correct!! If you don't flush your plants you're not gonna be able to tell the difference anyway. It's a sham! Said it once and I'll say it again. Drying and CURING are the keys to great smoke! I've NEVER flushed, and my weed is smooth and tasty...ALWAYS!!

I gotta ask, what nutrients do you use? and when do you stop giving them to your plants. This is old but i hope u see it

I've tried flushing and not flushing. Couldn't see a lick of difference. Using Genhydro nutrients in an ebb and flow system.

The organic versus inorganic distinction is totally unconvincing. We know what's in our water - that's what we like about hydroponic growing. There are simply not that many things in there that aren't natural or normal for the plant. What compound does anyone imagine is in there that an "organic" fed plant doesn't need too? I've tasted the water (before I started using Floralicious Plus). The flavor is mild.

I have multiple reservoirs and have run head-to-head tests. I had a friend do a blind taste test. He could see no difference.

I've cured weed badly and gotten mold. Had to fast dry in an attempt to salvage. That particular batch was flushed for a week. Another grower tried it and asserted the off taste was the result of not flushing. It gets a little old listening to people spouting nonsense as though it were sage wisdom.

That said, I'm not totally convinced one way or the other. Some people posted that it depends how you cure. That could be true. In tobacco curing, the taste can be affected by organisms that feed on plant starches. For us it may be that plant energy reserves can be used after harvest by either beneficial organisms or mold. It may be that pushing those reserves down by starving the plant makes for a more mold resistant product. I'm just guessing here, but at least that would explain some of the differences in experience.

I don't flush...although I grow in soil with all organic fertilizers, and it seems to me that there would be no need for it.........
