damn, that was fast. speed of light. in some foreign countries i've been to, when you are sitting in a line of cars and the light changes to green everybody instantly leans on their horns. i mean so fast that you know that they are poised, ready to go, inches from the button.

Thx for humoring me, IF.

I do like the idea of the pulse feed, as adding some kind of reservoir and automation is the next step I'd like to take, since it furthers my lazy tendencies, and there are cheap 9 outlet manifolds that would squeeze right into my existing set-up somewhat easily. Would I be accomplishing the same concept as a PPK if I added a pulse feed to the top of all of my little pots, and put a capilary mat in their drainage pan (which would sit above, and drain into the reservoir)? In the original/traditional PPK the wick seems to dip into the reservoir, where as a mat sitting in a drainage pan would only serve to draw the excess water out of the medium, rather than back up into the medium....but the original design was also depending on the wick doing the feeding, rather than the pulse, so would the mat solution be as effective? I'm a brokeass, in addition to being motivationally challenged, so the idea of re-using,and/or adjusting my current set-up to jam into the margins of the PPK idea is appealing, aside from just the fear of backstepping.

yes, this would work if you take a piece of the same capillary mat cut to fit and shoved or installed (doesn't "installed" sound more exact than "shoved" even though it may not be?) into the medium about 2" with enough hanging out to insure full contact with the capillary mat. this would positively drain the pwt after each pulse. the capillary adjustment for moisture content is the ability to raise or lower the tray the capillary mat is in contact with.

drawbacks are that you are going to have to do something about controlling algae and there is some thinking that needs to be done about how you would feed the system as the trough for the mat end has to be movable up and down plus maintain the same water level all the time.

compounded by two way flow requirements. a simultaneous pulse onto a group of plants is going to produce a volume of flow downward into the mat that is going to travel back into the trough, which needs to maintain a set level.

maybe a piece of rain gutter with an overflow at the needed level returning to the reservoir and a small continuously operating pump providing just enough flow to maintain the level in the trough or gutter.

the reservoir container could be fed by float valve from an elevated volume tank sized for whatever time frame you need.

for me a better way to approach this is from space limitations, if you have any.

"pulse watering, hand watering, drain to waste, float valve controlled, sub irrigated, what esle? self levitated..."


how did you know? we have a leak, people! goddamnit IF, i told you to at least slide wheels under it or something so people would think it was being supported.

actually, we are involved with it on this level because we are nerds. you don't have to know, understand, or even care about how or why it works, if you don't feel like it.

there is virtually no learning curve if directions are followed. we can take a wino from behind the bus station and turn him into a zen master horticultural guru in about five minutes. which tells you a lot about self-styled horticultural guru zen master's.

yeah, i've thought about writing and marketing a book but stopped when i realized it would only be a pamphlet. with cartoons, of course.

we are trying to simplify and speed up construction. and i think that people building new should just go ahead and use the 1/2" grommet and hose system that has proven to be so reliable in hydro apps over the years.

i use tire valves because i'm a cheap scottish bastard who likes cheap shit. oh boy! a bag of 50 valves for only 12 bucks! then i'll spend 100 man hours of labor on them to make them work.

there are three distinct steps that you can take to ease into this. each step will grow a plant fine and the components are retained at the next level. i'll try to start putting something up on that later today

cheap too!

Unfortunately, I have tons of space restrictions: I'm in a 28"x15"x60" cabinet, and trying to maintain some stealth as well, so I try to stay within the confines of the cab. Currently I've got a pair of 14"x14"X3" trays, which each have 9 2-liter bottles acting as pots (I take pride in ghetto DIY/re-purposing), and I just dump water into the trays for feeding, with top-flushes to waste every couple weeks. The trays are on shelving that can be moved up and down, with some space below, which is where I was thinking of stashing a small reservoir, but it's pretty tight underneath...maybe 28"x15"x12".

Thanks for another great breakdown, though. As I figured, it's probably not as simple as I was trying to make it, and magically re-configuring what I've got, in the space available, is probably a near impossibility. A pair of 5 gallon buckets would fit well in the space, which is probably what I'll start working from at some point, but as I said earlier, I think it's the hiccups associated with the switch SoG to vegging/growing larger plants that spooks me at this point, more than the PPK design/experimenting, which I would consider fun.

that's really tight and i personally have zero experience in an area that size. i think you need to talk to our resident cabinet ppk expert, the most patient grower i have ever heard of, Oldone, if we can get him this time of year. he's probably out on the edge of the ice with his harpoon spearing baby seals.

style of growing, large plants, small plants, plant numbers, horizontal or vertical lighting are not relevant to the principles being used here.

those grommets will leak before your ingenious tire valve-latex will. but they probably wont leak :)

we can also do thru-hull (aka flood&drain) fittings. the hole is drilled out, the threaded end is pushed thru and then the nut is tightened down over the gasket. I use silicone on them as well. BUT SO MUCH WORK!!!

the 1/2" line is really cool b/c the flow is speedy. but the installation sucks. I've got to use a hair dryer to get the hose to seat over the barbs properly. and 1/2" line (at least mine) is way more rigid...

whereas:

the tire valves are so quick to install. drill a hole and snap it in. done. if u have the right size latex tubing it is just pushed on with ease. thats it and it doesn't leak. plus it's more pliable so u can move PPKs around easier

on a new build out I'd maybe consider going 1/2" if I only had, say, (5) PPKs.

the tire valves are the industrial, multi-plant, long term use solution. you build it once and never f**k with it again.

¨Therefore, aliens! No, that's a different show. Therefore, predictable results.¨

but who gave us the ability to predict the results?
ALIENS! Tonight the new episode was about Da Vinchi btw

So I´ve been thinking about automation again,
Home depot has a $7 GE plug-in digital timer, should be capable of 20 on/off cycles with each lasting 1 minute. In Anti´s thread, Bobble? suggests using a t-fitting and in-line valve before the manifold to adjust the amount of water being delivered during that 1min cycle. This should mix the reservoir up a bit too. Still unsure about what size pump to order, probably a 396gph for around $30.

So lets say you got 20 clones in beer cups, SOG, DTW. Could you somehow deliver equal amounts of water while the inline valve is being adjusted? Looking to get ~100ml a cycle from each 1/4¨ hose. Maybe using -something- like a cap/plug on the end of the tubing where a smaller hole can be drilled and easily cleaned/unclogged? Can´t decide whether or not to have pressure in the manifold/tubing, or use the pump to fill up another bucket/reservoir with the tubing going into the bottom. Then just adjust the in-line valve so a ~gallon gets pumped in, and allow gravity to do the rest (within the next minute~s).

Would probably only feed during the day, with a 1min on/10min pause for lateral movement/1min on pattern every 2-3 hrs.

The in-line valve would have to go on the manifold side with a pump that size

just get a wide, low rubbermaid. actually buy (2). install a tailpipe (or 2) in the top. fill w/media. multi-plant in the same container. done.

Good advice, disciple. This is one of the first methods I gave some thought to, with the catch being that all the rubbermaids/totes I can find that fit my footprint are too small, and will result in me losing a couple of plants from each side, and centralizing my plants in the middle of my cab....which would be fine in a horizontal setup, but I've got a vertical, bare bulb, and that's the opposite of how I want the plants situated.

That is some tech most often associated with Heath Robinson... but DHF, D9, and our Bobble generation are all aware of it...

slops, I drew you a picture. I took a picture of it. Maybe I'll post. But mPPKs are wicked easy. In your space. One trip to home depot/ace/wallmart and you'z done.

it would be better though if I could deliver that 100ml ASAP from a simple 1/4" vinyl drip tube, more of a pulse, like how its currently being dumped from a cup. So any guesses on how fast this stream would flow when minimal pressures are involved, Im thinking it will only take 5-10 secs to get that amount? So this would typically require a much more costly timer, but Im already using the cheap GE model for the lighting. This is when the lost ancient alien technology would help.

I do have an idea to get that short duration of flow evenly across the multiple tubes using gravity, while being stuck with that 1 min runtime. The pump would be in a 20gal trash can leading to a 5 gal bucket/manifold located ~1ft above on a shelf. The T-fitting+valve would still be used to divert the majority of the water. The 20 -1/4" tubes, each 5ft long, would enter the bucket at the same height-about 3/4 the way up (just drill, angle cut +pull = sealed well enough?). Another 1/4¨tube near the bottom so it can fully drain each time, but it might require another valve/larger pipe here for adjustments. The pump will turn on for 1min each time, and if I can adjust the diverter valve slightly (and it doesnt change position over time), the water will only cover the feed tubes during the last 5-10 secs. Any chance this will work?

EDIT - cant decide whether to go with vinyl or poly 1/4"tubing? poly seems safer/stable, but stiffer so it might not bend/seal as well

dam surface tension/air bubbles may be an issue after a quick test with air-line. Bubbles stayed in the line after the bucket fully drained and it took a second or two after refilling to ´push´ them out. The line does seem to fully drain when both ends have angle cuts and the height difference is more than 1ft though

All my connections are made with black latex tubing.
Tire valve-latex-polytube

The manifold has tubing-latex-tubing.

In the future I could imagine some aero nerd will have a pressurized tank with a solenoid to the top feed of every bucket with some specific timed interval of so many ml release all powered off a 12v deep cycle battery.

was worried vinyl might offgas indoors, chose this poly tubing instead

Netafirm WHITE (PE) Tubing 0.16¨ID $7 for 100ft
Reflective white tubing is completely opaque to prevent algae growth, solid white for long term durabilty (not coated or layered white) producing COOLER water temperatures

Some parts of the tubing wont be shaded, and although they shouldnt have any water left in them between cycles, when less bacteria growth was mentioned - I couldnt say no. Pump wont arrive for a week though

Nutrients don`t accumulate in the rootzones JB , they accumulate in the plants when made to transpire/sweat at increased levels and that`s where burnt tips and all sorts of over juicin tells are seen with imbalances and lockouts sure to occur sooner than later, but.......

Just ta make yas feel better about what God gave me free in Hell with 80-90% RH 24/7/365 , and why after dialin my environment made my monocropped bitches hoon since forever , .........Go google "Vapor Pressure Deficit"........then...

You`ll see why not necessarily "slowin transpiration" with 70 % RH till end of stretch makes for that "Circadian Rythm" for the plants ta suck juice and sweat it out for optimal nutrient uptake and dialed shit ftw IME......

Gotta try it my way Bro......Guaranteed it`ll make yas happy......and....for the record........Texas Kid was always a stubborn old head like most of us old farts , cuz we were all self taught and learned shit the hard way cuz nobody ever did this shit before us , but .....

He did a thread at the farm way back runnin elevated humidity and ambient temp levels that Krusty had preached for almost a decade and ......

Hands down TK testified his yields jumped to almost double JUST by runnin Krusty`s 70% RH till end of stretch and then as low as yas can get it below 50% till end of cycle with major air exchange to prevent airborn pathogens from takin a foothold.....so...


Onward and upward Anti.....get that cheapass humidifier and keep the damn mist away from the bare bulbs with the extra air movement....and....dial them lights on/off temps
, and this might`ve fallen between the cracks but RH ALWAYS increases lights off and don`t mean Dick in environment dialage.....

It`s the light`s on levels that make the bitches hoon , and it`s harder to keep RH levels from soaring lights off without increased airflow and or runnin de-huey`s if needed , bet on it....

Lights off RH levels is what causes powdery mildew and gray mold/budrot without proper air exchange or dehuey`s burnin up......

Krusty usedta run sulpher burners if any PM was noticed , but that`s some nasty shit and not many folks runnin 3+ lb plants anymore.....so...

Good luck...Freds.........

Jbones... The intensity of the artificial light produced by lamps can be equal to the intensity of the sun, or more or less intense... It depends on how determined u are to dial your environment. The intensity of the sun at noon at the equator is 10k foot candles. 5k fc is the most that can be used for photosynthesis. Put your plants in the 3-5kfc, no closer... Cause then ur just waisting light.

As far as humidity is concerned.... Water is the key to life. The higher the temperature goes the higher the humidity needs to be. Humidity should stay about 10% below the temperature farenheight. i.e. 75F and 65% RH. 85F and 75% RH

This is from Antis thread stickied in the vert section.
Just wanted to share because I also have had great results with increased humidiy.
A solid 33% increase in yield.

VPD... I'm just getting it down.. 77F / 70%RH.. a weener. See Urban Garden Magazine, here: http://urbangardenmagazine.com/2010/07/plantworks-part-1-humidity-and-vapor-pressure-deficit/ , not that teh PPK didn have something to do with a great yield (for me) 2 >SSSDH = 12z/each, dry, 1 >SSSDH = 6oz dry and one F13= 6oz dry.. I'm amazed at this total, 34oz dry, 4 plants, 600w to 1200w hps (2x600w, stacked, naked. but a clone of that SSSDH that produced only 6oz, is enormous and will probably run the same 12zs or more.in a friends grow.. sameysamey F13..

here are some piccs of the tail pieces from them, the F13 was the dark wick, the sssdh was the other discolored wick and the two clean/cler ones produced the 12z/ea. when first taken out of the pot (top bucket) it was bright purple, now dark purple.. I have no clue why. all 4 tail piece had what looked like a giant dreadloc in it (roots andmedia). all else was the same.. I will say that the F13 smells/tastes nothing like it did previously but still killer. Any ideas?
