Wow 30x40 Congrats bro! I am happy for ya. You will be bringing the PPK to another level.

Where i'm going does not have those @#$%^&* smart meters that have time of use capability. I don't like the idea of a program that finds 12 hour cycles.

As time goes on I think that capability will be used against us more and more.

Later on

I promise I will get the flip flop tutorial done. Then your 30x40 could be two 20x20 rooms powered by one set of ballasts 24/7....@#$% a smart meter. Also leaving you with a equipment/trimming/drying area.

My space is 24x30 with 12-15 foot ceilings ..... no crapper or sink.
Framed up 2 12x20x8 rooms with storage above
You could go double decker in your space.

Oh yeah and reguardless of how safe your area is think about getting yourself a good dog, they call em "Mans best friend" for a reason. Your seasoned trimmers can hold down the fort and feed the pup while your gone for three months in Bali.

A few pics of my pulse and home run connections

A few pics of my pulse and home run connections

All hose is 1/2" Hydrofarm brand. The fittings for the home runs are 1/2" ebb and flow fittings.

From the top:

The manifold, which is a four way hose splitter:

Home run:

My medium is about 3 inches down from the top, and I wanted my halos to sit flat on top, so I drilled through the side of the bucket at the medium level:

The blue line in the pics above is 1/4" OD, and runs out the to volume tank.
The connection there is a tire valve with cap on, and a tiny hole drilled to slow the water trickle.

Lot of time went into your design, it looks great. thats not the Hydrofarm with the N-G-K on it, is it? Imaginary Friend and others had gassing problems with that hose (N-G-K). I've thought about 1/2" useage, almost zero % that it would clog in any 3 month period.maybe later. Let us know how it runs, please. Your pulse time must be 10 seconds.

 

[gregor_mendel]

Thanks. The time was mostly in value engineering to use things I already had.
None of this is really an attempt to improve.

thats not the Hydrofarm with the N-G-K on it, is it?

As far as I know, different hose, different companies.

My pulse is 28 seconds, but that is based on the slowest bucket.
The fastest one is about half that.

Wutt you meen? Slowest?? Fastest?? Different lenght hose to halos? Should be all the same, no?

 

[gregor_mendel]

Equal length hoses.

I should run a catchment test to see what is really happening.
Going on a visual of when water comes out of the holes, the rate is different.

Real clean build. Super impressed with the detail and good use of readily available equipment off the shelf. I always buy four hundred fittings to move up and down sizes and glue and jam and paste and fuckerize my way into a real Frankenstein set up. Yours is super clean.

You are slowing the volume tank to allow the pulses to drain and return to your pump chamber to maintain a consistent air gap, yeah?

Thanks IF! I have many boxes of grey pvc barbs, black hydroponic hose barbs, ebb and flow fittings, other bulkheads, poly hose, vinyl hose, greenhouse irrigation stakes, and the list goes on. I've been there. I've been there with bio-buckets, krusty buckets, bato buckets, ebb and flow, once even a 6'x6'x1' DWC unit.

But now I'm here. I'm here with PPKs. And all of you.

Yep

I would like to add, for anyone using ebb and flow fittings, that after drilling the hole, use a heat gun or sink full of near boiling water to heat up the plastic, then install the fitting. It will not leak.

In my home run pic, you can see salt stains above the fitting on the control bucket.
That is because this is a former bio-bucket.
I turned the ebb and flow fittings on the overflow holes to the inside, and used a short length of hose and a plug.
But I didn't use my heat-up-the-plastic trick, and they initially leaked.
It seems I have enough salt buildup at those fittings now to seal, as they haven't leaked in weeks.
I will replace that bucket at the end of this run, as the "plugs" poking through inside require my float valve travel to be angled.

gregor gets all industrial! nice. after all the ways you have grown, with all of your experience, you are gonna pull some serious weight.

hey, snook, how long did you veg? how tall did they end up? and what plant training did you use?

so, oo, how long were you out on the ice? you live 30 miles north of the lake and i used to live 30 miles south of it.

hl, there will be dogs. i'm probably just going to build one chamber first, but i'll leave room for a second. 16x24 ea should work for what i have in mind.

uh-oh, mrs d9 is home! gotta go!

They were veged under t5s for 6-7 weeks, horizontal (18-6), kept cutting them back to 18-20" >(all the headroom in the veg cab) put in the tent @400w for 1 week, 600w for 1 week and then bloom (12/12) 600w for 2 weeks, then 1200w for the rest of the run.. buds that overhung the lower light dried out to the point where I'm not sure a few days more, they might have combusted.. from here on out the last 2 weeks will be run from just the top bulb @ 1000w. they ended up about 3.5 ', and were run vertical scrog. Generally buds were about 14 inches from the lights. I have no idea why one sssdh and one f-13 didnt stretch much at all and only produced 6z each... the f-13, it is the 4th run of the same cloneage and the characteristics were totaly diferent from the first 3 runs (shorter/lighter color/menthol tasting/same hammer though..)... none the less, I didnt tke clones.

 

[delta9nxs]

thanks! you don't like clones and i prefer them. but i'm about to do an all seed run. i've got a bunch of strains i haven't flowered yet and need to sort out.

i thought that i had finished selecting one pheno of the old swt #4 but after about two years i began seeing slightly different expressions. at least two. both descendents of the same cut. i tracked them for a few grows and they were definitely producing two different cuts. i ended up selecting the one i used here and threw the other out. i have no idea how this can happen.

"Epigenic drift"


Random google copy and paste (in this case:http://blogs.scientificamerican.com...rning-point-in-our-understanding-of-heredity/) :

Epigenetics: A Turning Point in Our Understanding of Heredity

By Kara Rogers | January 16, 2012 | Comments7

"In a study published in late 2011 in Nature, Stanford University geneticist Anne Brunet and colleagues described a series of experiments that caused nematodes raised under the same environmental conditions to experience dramatically different lifespans. Some individuals were exceptionally long-lived, and their descendants, through three generations, also enjoyed long lives. Clearly, the longevity advantage was inherited. And yet, the worms, both short- and long-lived, were genetically identical..."

"There is increasing evidence that epigenetic modifications are transgenerational (inherited through multiple generations) in a variety of species. Examples include coat color in mammals, eye color in Drosophila, symmetry in flowers, and now longevity in C. elegans. These findings are exciting and raise intriguing questions about the seemingly limitless nature of epigenetics..."

Essentially, evidence suggests that it is possible for environmental factors to trigger a genetic 'switch' that effects physiological expression.

This suggests that a genotype's potential is much more diverse than the coincidence of its coding.

I.e. it is both nature and nurture.

Identical twins developing differently over time...

What is particularly relevant is that these 'switches', once 'switched', can be passed on in their 'switched' mode to future generations sexually.

It shouldn't be surprising that a genetic switch would remain 'switched' through cuts.

In this next bit: I'm operating out of my brains, without documented support here, but it may be based on something I read/studied in some life or another, but since plants can be stressed/flowered/tortured/over-underfed/influenced in distinctive locations, clone taking technique (i.e. which material is being harvested for the clone) can influence epigenic changes--that is, taking cuts from sections of the plant might be transferring weakness.

I've read (DJ forum) that taking cuts off of mutant sections of his plants do not always translate into fully mutant plants... that some displayed the same mix of normal and mutant characters, but this is both non-informative and well outside my personal experience...

In a thread I did read on this forum (something krunch? was participating in, if anyone wants to advance search it) it was suggested that taking repeated generational cuttings from the best part of a 'compromised' plant might reverse the drift... i.e. reversing the environmental conditions that may have 'stressed' the plant into the 'switched' mode might also 'reverse' the 'switches'... by steadily taking well developed, well fed, healthy growing tips exposed to premium light.

Speculation: Taking generations of cuts off of 'clean up' material might induce the overall lack of vigor we see in so may older cuts as the material we 'clean' is virtually by definition the weakest part of the plant. I say this as many people have reported having plants run many years without drift or loss of vigor. So... it seems plausible to me that clone material selection influences the epigenic qualities of the lineage-material.

Or some particular lineage-material might be more susceptible to 'undesirable' epigenic drift situations.

It has been speculated that this drift was the source of the cheese cut out of the (Skunk 2?) lineage.

But this is just shit coming out of my head through my fingers to the interweb.

I Really AM UNQualifieD to BE USING These words.

This is a better article:

http://blogs.scientificamerican.com...sniff-humans-and-dogs-sometimes-sniff-humans/

It talks about us excreting stuff that is food for certain types of bacteria that eat it and themselves create the stink odor.

I was immediately struck the relationship between microbes and root exudates in bio-dynamic organic grows... and my tendency to sniff soil and composts to asses it health... and understanding how to change the compost if it smells off to inspire a different category of microbes...

And then I just read about sniffing other peoples pits and asses and that alone was more than sufficient to amuse me.

I believe that gel-like substance clogging your 1/8" line is a type of beneficial bacteria. When I was running bio-buckets, the beneficial slime would clog airstones and screens. All it takes is moving water and a crevice where the bacteria can take hold. You could kill off the slime with hydrogen peroxide, but that will sterilize the reservoirs and may hurt yield. A better solution would be to switch to 1/2" lines to the control bucket. A larger diameter tube should improve the fluid exchange between the control bucket and the individual reservoirs.

My first rig was a DWC bubbler with a control bucket. I thought that the fact that all the buckets were connected at the bottom to the control would keep pH and EC fairly uniform among the buckets. Instead there was little migration of the nute solution between the buckets and a wide variation in pH and EC. What I ended up doing was to grab the control bucket and lifting it repeatedly to pump the solution to and from the control. The improved fluid exchange immediately balanced the buckets.

disciple, did you drill the valves? and use 1/4" id tubing? mine have never done that although i do get a little "hydro slime".

are you adding anything other than jack's and calcium nitrate? are you using ro water.

another thing is that higher temperatures can cause a higher level of bacterial growth. mine are in full contact with the slab, which stays pretty cool. my res temps are low to mid 70's.

i think the 1/2" id line would totally solve all problems with clogging.

All hose is 1/2" Hydrofarm brand. The fittings for the home runs are 1/2" ebb and flow fittings.

Hey Gregor, I really like your setup. Thinking of doing that very thing myself. Where did you get the hose manifold and also where did you get the 1/2" barbed female hose connectors that screw on to it? I can't find them around here and haven't seen them for sale on-line. What size pump? Thanks, man.

[gregor_mendel]

Thanks SH

Manifold
I actually got mine from a local hardware store.

The 3/4" female hose thread by 1/2" barb I bought from a local hydro store.
I haven't seen them before or since, but I will go and ask this weekend who they get them from.

The pump is 633 gallons per hour.
