When are the DWC guys flushing? 1 week before harvest?

Based on the answer to the first question, how do you determine that you are that timespan away from harvest?

I am approximately 2 weeks out, but have several different strains. I was thinking of one more rez change with nutes then flushing next week?

I know TokeKrazy starts at 17 days away from harvest, with 4 flushes
1st two weeks with FloraKleen like product 4 days/4 days
3rd and 4th with plane Ph water

What is FloraKleen? I'm thinking it's a hydro product to make the final product taste smoother?

Thanks,

For periodic res charge use to remove salts and other gunk
Let it sit in it for 4 hrs every 4 weeks, then in the final flush
17 days before harvest you do 4 days FloraKleen, then another 4 days of fresh FloraKleen, then 4 days of water, finaly 4 more days of fresh water, then harvest.

Why is Florakleen necessary? If the concept of flushing to is clean out accumulated salts you would want water with the lowest possible concentration of ions in order to have the maximum capacity to absorb the dissolved (ionized) salts right?

• Dissolves accumulated fertilizer salts.
• Reduces plant stress from excess and imbalanced nutrients.
• Releases nutrient bonds between plants and systems, also correcting nutrient lock-out

cool stuff, is that like clearex? or are they two different things?

Yes petty much the same stuff
Clearex

Does it list contents on the label?

I use it a little differently. I have been using GH 3 part which is high is salt. Which most nutes are. I drain my system every week and then refill with Florakleen, or ClearX they are they same thing. No need to ph it. Then water for about a 2 hr periord. If you have a ppm meter you are supposed to be able to stop the Florakleen watering when the ppms stop rising. That is how you know that it has completed its job. If no meter just water for a couple of hours or even a full day it wont hurt the plants. Then drain the system and refill with fresh nutes and ph water. You will see that your plants love this.

And for final flush I always like to keep feeding my plants up to the last moment possible. I have found that 5 days seems to be very effecient in a hydro set up for flush. On the 5th to last day. Treat with Florakleen then go ahead drain the system then refill with fresh water for the remainder of the feeding. However I like to continue to feed my plants the carbs there getting like Sweet and Boost during the final flush. Anyways I get good results doing this.

I'm slightly confused.

If you flush the res and add back plain spring water or whatever water you're using doesn't that take care of the salts? The salts are in the nutrient rich water, doing a flush should eliminate the salts, correct? What am I missing here?

There are salts accumulated in the medium and roots as well, which I was thinking about flushing manually by running water through it. This is why Florakleen doesn't make sense to me, salts are soluble in water and therefore adding anything to the water will decrease the amount of salts that can dissolve in the water. This is basic chemistry.

Good point.

We might be dealing with another pointless product thought up by the marketing scallywags. A nice root rinse and a thorough cleaning of the res should eliminate 90% or more of any left over salts. I wonder if anyone has done any comparative experiments in this area? I'd rather not spend more of what little money I have left on something that I really don't need and can do myself.

I wonder if Florakleen is meant to be absorbed by the plant?

So to further muddy the waters on flushing a DWC if you think about it you should need minimal flushing compared to other systems. In other hydro systems you have all the added equipment (pumps, pipes, trays, etc.) for salts to accumulate so you would need to flush the system. In soil/media you have a bucket full of soil/media with accumulated salts so it would take a while to wash that all out. My DWC rez's get broken down every week and cleaned out with H2O2, so the only place for accumulated salts is in the rockwool and roots, which I can flush with a hose in minutes not days.

That leaves "flushing" the plant itself, which is really just a matter of giving the plant enough time to absorb clean water and dilute the levels of nutrients in its capillaries.

I think you're right.

-the Corsican.

sounds like that makes sense... I would rather not spend money on something I don't really need too.
