DWC flush

[abadtrip]

I was wondering how many gallons of just ph water do u let your plant drink before u harvest it.

[Burny]

I usually flush for about two weeks.

[abadtrip]

In DWC? my nute secudal says 2 days wow now u am really worried

[Burny]

I always just used this.

Just to throw this into the mix: I've been reading articles against flushing because they say it causes the wrong kind of stress at the end. Also learned that if I have not been over-feeding all along, THAT is a continual flush of sorts.

Check out this information:

I'm still researching this, but I would like to see some scientific evidence on the value of the final flush...

abadtrip We all know pure sativas need less nutes, but it's going great with my hybrids, too. I don't see any signs of deficiency.

Aloner I've created a MONSTER!!!!

That's awsome

When it takes over a city, we'll all know who's to blame!

Flush with a res full of pH'd water with your hydroguard for 2-3days for DWC. DO NOT PUT SUGAR INTO A DWC.

Sugar daddy is a nutrient not sugar I have been using it since day 1

[Tazard]

LOL sry, but 2-3D is plenty.

[Burny]

Why flush at all? Couple of days isn't going to change anything.

[abadtrip]

I think it would if a plant drinks 20 l a week I think it drinking 10l would do somthing

[Tazard]

Flush time varies from 0 to 3 weeks depending on how the medium holds the nutrients. In DWC you change 99% of the medium. In super soil you don't use added nutrients during grow. In soil (longest) it holds nutrients. Coco falls in between. In any flush soon as leaves show stress (yellowing) she is done.
Hope this helps.

Kinda what I was thinking about the leaves. I am kinda going down this same rabbit hole on another thread

[Tazard]

It's all on GWE

I have read that but it has two weeks on the recirculating nutrient schedule. Kinda contradicts itself. I've actually tried both ways. I think longer is better. I flushed one of the plants that was in the GWE newsletter for 18 days.

I guess (just imo) you would need so long (2w) for recirculating since the medium is only wetted on the lower portion by flooding and the upper 3/4 of the medium is fed by capillary action only.

That nute schedule came from the bubbleponics tutorial. Idk.
