A Demonic Deluge

hey, gregor, i don't think going up in tailpiece diameter will help grow a better plant.

in fact, if you are planning to go to saturation pulsing in the future you don't want the medium draining real fast as it takes longer and uses more liquid to flood completely.

also, it's my understanding that the big and chunky perlite is not as efficient at aerating as the smaller stuff because of the trapped nature of the air spaces in perlite.

Thanks D9

I agree, the larger tailpiece will not help me grow a better plant. The idea was, if using large perlite, which can be huge, the tailpiece would be hard to pack with a medium similar to the consistency of the rest of the pot. I have seen individual chunks in #4 that are 3/4".

I have not read about the lower efficiency of aeration with large perlite. I will look into that. Thanks for the heads up. The only reason I was interested in using it is that is the only perlite I have ever used that stays put.

As for the saturation pulse, I am already there. My Rio 700 GPH took a crap (used for 4 plants) The only other pump I had laying around was a Danner 1800 GPH. So I added 1 plant, and I am rocking that at the moment. Overkill, but I already had it, and it doesn't blow my halos off.

mrs d9 took this one from outside the door. that is how i get in and out. my hand is between 2 plants.

get ready, the larger diameter containers do make bigger plants.

I think that pic should be the cover of your b grade horror movie.. You should go back and edit it into the first post of the ppk bible, I mean thread.

Im already scared that your plants are going to kill you, it took you so long to trim last time.

The plants are plenty wide I just need them to get taller now.

I am confused as usual, quotes by D9 and IF:

this run i intend to use the "saturation pulse" technique introduced by Imaginary Friend. the idea is to do a full displacement of the root zone gases with each pulse by totally flooding the root zone. then allowing it to totally drain before firing the pulse again, thereby drawing in a new full volume "breath" of fresh, corrected, gases.

previously i have been using partial pulses of varying volumes and durations experimentally.

because of reservoir size restricting my volume i was not able to deliver a full pulse for about the first 2.5 weeks. i would say that i was doing about a half volume every 45 minutes.

Once you hit full saturation, there is no such thing as overpulsing...

How do you quantify a full pulse?

How do you know when it's drained?

"How do you quantify a full pulse?"

a full pulse is a complete flood of the root zone.


"How do you know when it's drained?"

when the float controlled solution level in the reservoir returns to it's pre-flood level.

I am once again bombarding you with questions. There is certainly no rush to answer these.

"How do you quantify a full pulse?"

a full pulse is a complete flood of the root zone.

"How do you know when it's drained?"

when the float controlled solution level in the reservoir returns to it's pre-flood level.

More or less you monitored the res. and set your timer based on this?

With this change, are you no longer concerned with limiting the duration of the pulse and that goes hand-in-hand with what IF said about not being able to over-pulse?

Full pulse throughout the life of the plant?

I'm a little late to the party... sorry.

If money is tight oil drain pans are only a few bucks, short and wide, cheap ones probably aren't as sturdy as the tractor supply tubs though. The tractor supply tubs are listed as 7 gallons... is that accurate? How many gallons of media are you using? If you're using more media couldn't that explain the increase in plant size? The reason I'm asking is the oil drain pans I'm eyeballing are only 2 gallons.

I know 2 gallon buckets have been discussed in another thread but what about a 2 gallon bucket with 2 gallon upper container. I believe the problem with 2 gallon buckets previous was due to their short height the air gap would be hard to "tune". Wouldn't this change with the new shorter top bucket.

The height of the original ppk setup has kept me from doing it but the idea of shorter and wider has really got me thinking. An oil drain pan on a 3.5 gallon bucket is no taller that my current false floor, DTW coco smartpot setup, and 2 gallons on top of 2 gallons will actually buy me back some headroom. Better growth without having to collect and dispose of all that drain water... NICE.

Thanks Johny, seen those before on your thread... kinda expensive, no? Are they rigid enough for monster plants? I feel like they're rubbery/not meant to hold weight on top of them.

The only concern with limiting the duration of the pulse relates to the return rates of your lower buckets--that is, you don't want to burn out pumps, or allow your top-off to over-top-off.

With regard to not being able to over pulse--yeah... the only real thing that matters in a saturation pulse scenerio is your frequency.

Mine held up pretty well in veg, I'm about to find out how well they do in flower with a Casey Jones and a Super Sour OG and hopefully in 6 weeks some clones of the ducksfoot plants I'm trying to reveg...

I'm not really after the biggest plants, I use PPK's for ease of maintainace... Once a week make RO water and mix Jacks, raise light, prune plants..

I guess I could go organic ppk to keep it interesting!

dude, you are a weed growing monster! your setup needs it's own tv show.
i lost track of the end of the last show, what did you pull from 6K?

I have a feeling D9 has been Jumanji'd by his PPK.

At this point I enter my room with a pair of loppers and a machete in my hands. I had to trim a walkway through some of my plants yesterday.

D9 I think you should trade a couple pounds to W. Wonkas Oompa Loompas to trim for ya this round.

Shit happens.......Adapt or perish.......

Walk toward the light D9.......

Peace......DHF.....:ying:.........

Hey D9 I am wondering if you mind talking a bit about your special veg cycle.

A quick description of what you do and why you do it would be most appreciated.

Many thanks.
