i don't Goop my screens at all. they are held in place by the media. easier to clean both buckets and screens that way and/or just replace the used screen w/new.

depends on how many ppk's ur dealing with.

for the tail pipe, D9 advised to just cut a 4x4 square (roughly) and pop it down the pipe w/media.

I still zip tie the screen to the outside bottom of the tailpiece, it works fine.


I tried it and it has worked since. what i do is fit the side screen first then place the square over the hole for the tail pipe. I put a bit of media in the center of the square screen and then push it down the pipe. that way I know I have media from the end of the tail pipe to the top and so my wicking action will be great.

I did have a tricky time getting the top of the screen to be close enough to the side of the bucket so that media (turface/perlite) didn't run down between the screen and the bucket and out of the holes.

I do not have the patience to accomplish this task.. tack down one side the other pulls away, move it to the bottom of the bucket the other side moves up.

It was easier with the media wet b/c it packed down more and held the screen in place.

u can either clean the screen or use fresh screen next time.

I'm hopeing that I wont have to screw with the screen any longer.

I just loaded some ppk's a couple of days ago. this time I just kind of made the screen wide enough to fit from top to bottom inside the bucket. SUPER EASY now and no hassle. Speedy fast too!

I didnt give this idea any thought but a good idea. I'll go this way if the 1.5" squares dont work as expected. Thanks for the ideas.

Alright.

Everyone reading:

Not for this thread, but I think that for the next fifty-two hours, when you see something decent on this site, you should take the time to acknowledge it with a 'Brilliant' reply.

Thanks everyone for your continued refinement of this system. This long-time lurker of ICMag is finally close to putting it to use.

I need to get my posts up to 50, though, so that I can post pix. I need to follow IF's instructions, and go post in all the "Brilliant" threads…

Hey fellow PPK'ers ! So my room is up and running nicely, but my pH is running high for some reason. My first "batch" of solution I attributed this to rookie errors...letting some of my coco dry out, which I hear raises pH, as well as on occasion letting a bucket or 2 of my RO to sit overnight, which was drastically raising it as well. However, now that I just recently emptied and changed the reservoirs, starting with fresh solution, it is still running high....Right now my black box is at 6.0, the control box within the black box is at 5.5, and my individual reservoirs are between 6.3-6.4, and I know the girls could be happier. Has anyone had this issue while running coco before? I'm using Atami coco, 3:1 perlite, RO water, and Jack's/CalNit 3:2 @ 600ppm. Anyone have any thoughts? This makes me think it has something to do with the coco, because my other numbers seem to be spot on with delta...

 

[ImaginaryFriend]

Jack's/CalNit 3:2

By volume, weight, or EC?

I run it 1:1 by volume... But running it at 1.2 EC always kept my bulk reservoir closer to 5.8 ish... (I presume your 600ppm is at a .5 conversion.)

Are you pulsing?

IF, thanks for the reply. I'm using 3:2 by volume, like delta said he is running. I know that's the ratio he uses, I'm assuming that is by volume delta? And I am pulsing, every 90 minutes, around 40 ounces per unit.

Hummmm...

What makes you think your plants are grumpy?

Can you post pics?

Strains?

Etc.

Knowledge is power.

Be careful how you share it.

But if you share it, someone here will help you solve the problem.

(Media? BTW, 6.2-6.4 isn't crazy far outside of anything... well within the nute availability spectrum.)

EDIT:

letting some of my coco dry out

A 40 oz pulse every 90 minutes should preclude this possibility.

Unless:

3:1 perlite

makes this possible, but that seems unlikely. But perlite will allow a media to dry faster. So.... there's a million things I'm speculating on right now... If you can clean pics from personal data, etc, and have a secure location to upload, pictures would make a world of difference.

Hey IF thanks again. Currently I'm running an OG cut, as well as Blue Dream. The Dream look quite healthy, but the OG seems to be a little stressed. The leaves are fairly droopy and not relaxed, with an occasional curl and twist. My brother is a long time grower and agrees it could be looking better. Since we came to that conclusion, I changed the reservoirs 2 days ago, and the newer growth does seem to show signs of a minor rebound. I was surprised that the pH was decently higher than when I put my fresh batch in 2 days ago, but still a tiny improvement from about 6.5 to 6.3.

The drying out of the coco was my fault, and occurred several weeks ago, to about half of the units. I essentially staggered my transplants, but filled all my buckets at once and put it all into the system. Silly, I know, but hey ya live and learn, and no major harm done (knock on wood). But I don't see why that would have anything to do with my new batch being fairly high as well...

About the pics...hmmm I'll have to read up on the process of doing so. Btw, I know OG is a tough, finicky strain. Not an ideal one for my first sizable run, but I'm a huge sucker for her. I just want to get things dialed in as much as I can before I flip the lights in about 2 weeks. Thanks so much again.

"I'm using 3:2 by volume"

this is the problem. volumes are 1/1, not 1/.67 or 3/2. equal volumes get you this ratio automatically, approximately.

i should have realized this sooner. i kept coming up at a loss to explain those ph figures.

do you have meters or are the ph test done with strips?

if you do not have a tds meter use a rounded 1/4 tsp of each per gal.

volume = equal amounts

weight = 1/66

ec or tds = 1/67

Hey Delta, cheers I am using the Combo pH pen, and have checked several times to make sure it is calibrated properly.

Ahhhh, ok, so equal parts volume, excellent. I'm glad we could pinpoint something, now lets just hope that's what it is

EDIT: Fucked up and crossed memories from a different thread:

So really, my question is what is your EC in your sub reservoirs/control?

(Could be something media related too... like running uncharged coco and it's picking up cations out of solution. If that's the case, running the system for a while with a 40oz pulse should self correct. You might need one more reservoir changout once the media is charged, and then it should be smooth sailing from there.)

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?

Congrats.

grown in 3.5 gallon round bucket PPKs or rectangular 3 gallon roughnecks?

I'm still in 2 gallon PPKs and perhaps too lazy to drill out and replace with 3.5 gallon buckets.

Thanks. they go in black/round, 3.5s'. Imay try the rough necks but I just went to 3.5s with only 1 row of 3/4 inch holes, instead of 'many' in rows, and less to screen... ha! I'm betting that each of 4, will put out 12z, or more, this time.

meter, 360ppm Jacks, then top to 600 with CN. Only use the TDS meter to mix with.. no ph readings. Veg thru bloom. This last run, I 'flushed' with straight RO for 2 weeks, I'm thinking I might have just lost weight.. taste is the same.. the shit make you say to yourself.. "I am, REALLY, high". TKS D9.

 

[Hossauce]

any chance he needs to feed heavier? when nutes get used up (or bind to coco?) pH rises.

maybe the confusion in the mixing meant the solution was a little light on nutes to begin with and then w/plant uptake the pH climbed?

or is my commentary redundant?

(like I noticed a difference going from top lit to one-side lit.... then from one-side lit to 4 sides of lighting.....)

Not redundant at all sir, I appreciate the feedback, and have thought potentially the same thing myself. Going to give it a day or 2 to hopefully see some results as is, and if not, I may consider doing so.

Also good to know that could be a possibility as well. Either way, I'm narrowing it down and am definitely on the right track. Sorry, I forgot to check the EC before I drained the system again this time, but will take note if I happen to see the ph rising again.

 

[high life 45]

I having some similar issues but the ph was low. Check out my thread and tell me what ya think. I hope these girls pull through.
