Flushing in DWC system

[scared crooked]

Hey there :p

So basically I was wondering how long one should flush using GH's Flora Kleen product if you are using a DWC system and had been feeding GH products, Sugar Daddy, a 0-13-14 bloom enhancer, and SM-90. The Flora Kleen bottle say 1-2 days for final flush, but the store clerk said anywhere from 3 days to three weeks. I googled it too but found only lots of "the last few days", nothing specific.

Not sure what to do here. I don't want things tasting all chemically, and I've got conflicting instructions, and I don't want to go too past the ideal harvest time. Help please :))

you guys rawk ;)

We'll need to see some pics to answer that question. Hehehe :D Really, what your waiting on... are the tricombs.

Once they start to turn amber - flush for a week to ten days (your choice). I've flushed for 3 weeks with no harm.

If you want to let them go even a little longer (after the Flora Kleen flush) you could use plain pH adjusted water .

Here is a simple and proper way to flush your plants in a hydroponics system.


With the GH product I use flushing takes about 3-5 day's at the end. You change the water every single day; but the most important thing to do it to watch the PPM.

On day one for example:
Your water starts with 25-75 ppm of clean water. You adjust the Ph and mix in the florakleen now you are reading about 150 to 200 ppm at most. This is before you turn on the pumps (just the ph adjusted water and flora kleen) Check the ph a few times a day it will change on you often sometime.

Day 2 before you change the water out check and record the PPM it will be somewhere around 500 or more

Repeat the same steps you did on day one to change out the water. Yes you change the water everyday so you are going to use a lot of water. Now you may not need as much as you did when you went 7-10 days between changes so keep that in mind. For 40 plants in a drip system that normaly used 20 gallons of water can flush with 5 to 10 gallons of water.

Day 3 check and record again the PPM before you change out. You will start to notice it will drop in PPM over the 24 hour period. This time it is probably around 350 to say 500 ppm.

Repeat the same steps you did on day one to change out the water. Keep records of your ppm change at the start and again at the end when you change them out.

You change out the water everyday and check your Ph several times a day there aren’t buffers to help keep Ph in check anymore so you need to pay close attention yourself.

You keep up the changing out of the water everyday until you have less then 50 PPM change over 24 hours from what ever you started with.

You can do one more flush if your Trichomes are not to amber just because; but you don’t need to. It’s just a good idea if you do this will make the plant use up even more stored chlorophyll and that is always a good thing to help speed up the cure time.

That is a proper flush and the way I personally track and flush anything I grow in Hydroponics.

I hope that helps.


*********************
When to know it's harvest time?
You must have a 30x lighted pocket microscope to view the trichomes and use the average I suggest.


What you are looking for is, small drops all different sizes and shapes on the buds and leafs. Then you will see the little odd shaped round parts rising up. After that it starts to look like an odd shaped ball on a stick sometime bending or falling over. The "T" part will stretch and the odd shaped ball will start to get rounder and larger. The "T" part will straighten out and bet stronger. When you are close to harvest you will see round balls sitting on a "T" it will look round and full then turn cloudy. Amber is after cloudy and you harvest on the average of about 10-20 percent of what you see when you look through the microscope is amber and 70-80 percent is cloudy. There will still be some clear so you harvest on the average. Check in many places all around the plant and give it your best guess is all you can do.

Hope that gives you some help

Peace
