Thanks IF. I know I am a pain in the ass, but this raises more questions for me.
I thought that since the plant is fed via the media wick, the purpose of pulsing from the top was to flush the concentrations of salts that build up in the top of the medium (from evaporation) down into the res, to keep everything balanced. I gather that the as the water is drawn through the medium it fill draw fresh air in to the root system and displace the "bad air'.
Is this the primary function for the pulse feeding?
So you are saying a ~250-500 ml pulse every hour would work better than one larger pulse per day?
how would this make it any different from a top drip hydro system? or if using larger pulses would it not essentially be an ebb and flow? Is this the point, it just has the media wick to keep the roots out of the reservoir, and as a backup feed source just in case the pump stops working?
My head hurts.
I am way to sober for this
I am going to the hardware store so I can get this damn cabinet finished.

Since you're asking me, I'll say that the highest rate of flow you can deliver to your plants to the point of saturation--better yet: surface puddling--is better than slow pulsing frequently and large pulsing infrequently.
The pulse tech started out from coco slabs w minimal run off drain to waste (conventional crop) gardens.
PPK recirculates, so has different considerations.
It is fed by the nutes in suspension in the solution, which it access through both the pulse and the media wick.
Also very true. So we have a few very nice things happening.
Also true. I suggest that in most circumstances, replacing the 'bad air' more often is better than replacing it less often, and that replacing more of it is better than replacing less of it. Hence my recommendation for frequent 'saturation' pulsing.
Saturation pulsing hits way harder, so it would be a "top-flood/top-dump" system. But a PPK is also a wick system. The wick moves the PWT out of the root zone, and maintains a consistent baseline moisture profile between pulses by moving solution up via capillary action as the plant removes it from the root zone.
One of the very nice things about ebb and flow is 'bad gas' displacement. So while a PPK is not essentially an ebb and flow, it incorporates the best features of an ebb and flow. (And it's humidity buffered).

Nope. It does all the awesome things that a wick does, and a top feed does, and an ebb and flow does (saturation pulsing).
And it's called a Passive Plant Killer.
So there is some Irony too.
Because it's not passive (anymore).
And it doesn't kill plants.
And now, DocCrow your on the inside of a grand joke that--at the beginning--wasn't a joke at all.
Double Irony.
At least double. Maybe more Ironic. I haven't given quantifying the Irony enough thought.
I have other stuff to do.
But when I think about it, what is more important than quantifying Irony?
I like to eat and sleep. But then, next priority: Quantifying Irony.

Hey DocCrow, these guys really know their shit, eh?
OO
Whats more important? Growing, jeesh...but you dont need me to tell you that, right?

And boring.
Fucking-god-awful-boring.
So don't forget the boring part.

hey, DocCrow! welcome! sorry i'm late responding but i've been tied up in the jungle for a while. i was lost for several days but found moving water and followed it out.
i see that your questions have been well answered already so i'll just say good luck.
later, d9

Don't mind ashes; he just likes to swear online.
I think he lives a very repressed life in the real world. And adopts a bad-assish stance on a weed forum.
To make up for his very repressed life.

Well it took me a few weeks but I managed to read the complete thread and consider it to be the best thread on all of icmag. This thread has the best useful info versus BS ratio of any I can remember. Everyone is able to work together while exploring their own ideas with very little of the trolling on most other threads. It took a while for the way the system works to sink into my head but it's actually a very simple system to build and I can't wait till I get a chance to set it up for myself. It's an amazing way to increase yields while doing less work. 3 cheers to D9 and all the other contributors!

I built a ppk and stuck a rooted clone in it yesterday... I used a smart pot with a 6" tailpiece in a 3 gall Rubbermaid tote...
Hope it works out... It took 10 minutes to build, I think the hardest part was packing coco in the tailpiece...

I almost didn't because it was so difficult to find pictures of how to do it... I've been reading this thread since the day I joined this forum and its pretty hard to find things even with the link thread on the first post...

I feel your pain and the others that have questioned the build as I did myself. It would be really nice if someone intimately familar with the build would make a nice DYI with lots of pix.
I'm pretty sure I have it in my head now how to build it and exactly how it works but I took the time to read the entire first thread along with all the others on the ppk.
D9 is having to delete pix from the first thread to make space for his new thread so it can't be him. It's hard to read thru the first thread and fully understand the system when there are no pix to go by....just saying.
Anyone care to step up?

here's the deal with this thread. it is the experimental R and D thread. this is where it evolved and how it evolved. but you don't have to sift through the whole thing because all technology and valid operating theories were brought forward here as we went and are now shown on other threads.
we have discarded the old and moved on with the current "new".
each new change was tested multiple times and adapted or rejected.
the deleted pics just show the progress and not the final version.
in the wicked pulse thread i have tried to show all the components of the build and it's operation.
i just looked at those pages there and it is about as good as it gets for showing my current system. all elements have been included
i have shown a hand watered version and explained how it is upgraded to a pulse system. same components.
i have shown a state of the art pulse system and how to build the reservoirs, pump manifold, and the float control/metering box.
i have discussed plumbing alternatives on that thread too and explained the differences between the versions.
all of these guys in the links below have done a great job of explaining this device many times.
i'll try to put something even more direct and compact together soon but right now i'm up to my ass in it and it's getting deeper so it could be a while.
it's all there in the wicked pulse thread. and the pertinent info is on just a few pages, perhaps isolating those pages into another document would help?

Zeke had a nice little post where he linked pertinent new build details in the wicked pulse thread. Really all that is necessary is to put one of these together, a few hours worth of work, and sit back and watch as you grow the healthiest plants ever. At that point you will have so much time on your hands that you can read every one of d9's posts and get all of the knowledge and shinola you can handle.
Everything you could need to know is in the post below. If you have questions ask one of us we would be more than happy to assist.

No I'm fine now as I said. I know the word has to be going around about the ppks. As I read the thread I saw the attention it slowly received. I realize the system is fairly simple and straight forward and cheap to boot. My intention was to bring to light how complicated it can seem to a new user trying to get setup. It will be months before I get a chance to put together my own system. I live on the east coast and am wanting to move to Washington after I see what the election brings far as president and 502 before I make a final decision.
