How do I properly flush guys?

[Team Microbe]

Do I do the typical 3x gallons of water per pot size?


Or do I simply feed with straight water for the later 2 weeks of flower?




Much thanks!

I always do the last two weeks of flowering and I usually feed lightly through. That's when I use soil. In hydro in flush for 10-14 days and usually run the food a little higher throughout flower. Lots of variables to consider.

2 weeks, straight RO only, i give until I get TON of run off.

The 3x through the pots is flushing , the 2 weeks of plain water is leaching , & thats what 99% of growers call the flush before harvest .
if you mean to flush before harvest then .... the 2 weeks of leaching is what you want to do .
if you have a problem during flower like a PH lockout or over nute situation ... then you flush 3 x the pot size in plain water .

ahhh, I see. So if I'm in organic soil I should just be feeding with water pretty much? not in any accessive amount?

Dans termanology is spot on.
Most growers refer to the final 2weeks of water-only as flushing. Which makes it hard to distinguish what they mean exactly.

My suggestion is to leach with straight r/o for the last 2 weeks. With 7 days until chop, flush once with 1x water per container size. Maybe less even. 5 gal smart pots I flush with 3 gals. of water. Stuck the run off out with a Turkey baster.

In true organics though, theres prolly no need to actually do any "flush". 2 weeks of plain water at the end is prolly fine.
Thats my two cents anyways.

haha I use the turkey baster too! works like a charm right?

thanks for the advice, I think you may be right about organics not needing a flush. I'll use RO water for the last 14 days though, maybe even some molasses for the first 7 days too

yup , just feed the amount you usually do but with plain water .the molasses is a good idea !!!

Organic no flush, just water the last 2 week. With Chemicals, flush with at least equal to the container size, more if you can, then just water last 2 weeks. Flushing is more important with chemicals than organics were it is not needed. You flush for flavor to get that chem taste out. Either method no ferts last 2 weeks. Organics won't be able to break down fert in time to use, chem you'll get the chem taste back.

I never do any flush unless i have a problem . I just leach the last 2 to 3 weeks & always get a nice clean white ash & no chem tastes .

leach as in feeding with just water? flushing is pouring 3x the container size through to get salts out am I right?

 

[pappy masonjar]

Yes.
Leaching= plain water for the last 2 weeks
Flushing = pouring 3x through the container.

(And it doesn't necessarily have to be 3x btw. 15 gallons of water through a 5 gal container seems overly excessive imo.)

ALSO, remember, most growers refer to both as flushing, so its kinda confusing.

Bottom line, if your growing organically, plain water for the final 2 weeks is all you need to do.

i never flush i feed the right way and just water in the end.

Much appreciated, I've never known the difference between the two! ahhh... the wonders of ICmag

I flush with clear water every two weeks but that's just to remove salts from the soil as I'm growing. When it's time to harvest is the real flushing for taste. Pull the plant up gently and trim all the roots off except the main tap root. Then stick the plant, root first into a small mouthed one gallon jug of clear water. Then put the plant with the jug back into the 12/12 light cycle with the jug of water buried in the soil up to the mouth so no light hits the roots. I put an aquarium bubbler down into the jug too. This will keep the plant looking just as healthy as if it was never pulled for about 3 days. It won't wilt at all and then cut the colas and hang them in front of a fan for about a week. Trim and Cure. This ultra flushing will make your weed taste a lot better.

Wow I guess there's a first for everything... In my 10+ years doing this, I have never heard anyone going to this extreme to flush in the end. No offense, but I actually lol'd.

Just leaching with plain water in the end has always worked for us.

Do you grow you grow vegetables indoors, in containers?

I see your point and am not a big proponent of flushing for "taste" but whenever I see someone reply with the "farmers dont flush their ...." comment, I have to point out that it is really apples & oranges.

Indoor potted plants and outdoor garden or field grown crops are much too different to assert that something that is good for one is good for the other.

Im with you though.

As for flushing or leaching; this is what I understand from what I know about plant biology.

Leaves are "stores" and flowers & fruits are "sinks" The stores stock the nutrients. When their is a shortage, the sinks (flowers) draw the nutrients from the stores (leaves).

So when your leaves turn yellow after you flush, those elements haven't disappeared, they have been drawn into the flowers (buds) so that they can survive.

If you dont provide the nutrients for a long enough time, the stores will be exhausted and the flowers will use up what they have and die. I havent seen anyone harvesting dead plants.

Maybe I am missing something.
