don't some fishing weights (lead) have plastic coatings? or plasti-dip them?

Yea I've contemplated just spraying plasti-dip on washers, and even read its safe for aquariums. However, I haven't seen anything that says it won't react to nutrients/salts/additives, etc.. I'm not 100% sure it won't leach because of that.

I got some, but I also got a big bag of this: https://instamorph.com/

I hear that some krylon fusion spray paints work fine in salt water aquariums too. No flaking after years and years. I know if would flake off metal though, getting moved around and rubbing the bottom.

even stainless and titanium leach crap out into water. nothing is safe except a nice river rock. lol

DWC? RIU's given me more jargon and terminology than I ever thot possible.
Here's a link on DWC, that gave me a primer on what it is:
I hope I didn't highjack the thread or anything here.

Heh, while we're talking DWC, the OP will want air pump + air stones.

What are the guidelines for setting those up?

cut your hose lengths the same, feed them through holes drilled under the lids hook your airstones to the ends in the buckets and the other ends to your air pump. Not much to it. Use black tubing to keep light fromfeeding through into your res

DUTCH PASSION KILLED IT ...With this write up...but there are some MINOR THINGS That ONLY Experience Can Convey.
The Images Are Spot On...for DWC @ 600w+
That Is Why I was So comfortable Growing under a 432w T5...

My actual bud Structure was Just BIG Enough to Grow MEGA CHunky "Smalls"...
Nugs where the size of a Quarter.... not Golf Ball Size Nuggz...Just Larger Than DIME size LED Nuggz.
A 1000W or The AT600 gives Me 10" x 10" Fan Leafs...

I had to drop My Plant Count to 4 in a 4x4 Tent...VS 8 buckets with T5,s OR 16 in a SOG Grow Style
I can Pull 6 - 9,,,In SOG Style with The AT600...

This Is How Roots Express In SWC...
You have to TOP FEED Thru 10" Net Pots Of Coco Powder...IF YOU DO IT WRONG ...The Coco FALLS RIGHT THRU The NET
Do it RIGHT an THe COCO will produce Ultra Fine Root Hairs That can GIVE you Super Soil Advantages In DWC


I actually found This Pic...Im doing too Much lol

Air Pump
45 L for 2 buckets
70 L for 4 buckets
I started with the shitty Auqa Air with the dail up power knob
I moved to (4) 45L pump & never looked back
Then 70L

The right AIR STONE will give you Champagne Quality bubbles that pop OFF the Waters Surface Like SPRITE

Here You can See....The Nitrogen Starved EmDog...It has NO Air Line...Its all COCO top fed --but It was recuse cloned
I burn The Fuck Out Of It with a POWDER Feed...Had to clip & root quick.
If You Follow The Air Line...You can see Bodhi's Pura Vida RE-Vegging ...Its Roots JUST Hit Water

Great description!

If I understand, that's a 70LPM pump for 4 buckets that are…5 gallons each? I've got 28 gallons of nutes which is about 50% more than 20 gallons so I need about 70 +50% ≈ 100 LPM?

Its tough to fit (4) 70L pumps in a 4x4 tent...with 16 buckets, air lines, & a power strip...Plus (2) 8 bulb T5 Fixtures
You need to keep the AIR LINES equal in Length to prevent Uneven Air flow to Your Air Stones....
THEN, You Have to Stream Line Clones @ 14/10 Light Cycles ...Until The Roots Break The 10" net pot Bottoms...
Then Lolli PoP to 4 Main Nodes & FLIP to 12/12 or 11/13...
Each bucket is about 1ft ...so 4 buckets in a row @ 4 rows...
Each Clone Should put out 2oz MAX...
I prune Hard AF...to avoid canopy issues.
REZ Change is a PITA but 2 lbs. in a 4x4 is GOLD. (Was Gold...Its not even cool to pull that type of WT. any more)
You need to know The Strain Inside Out before You Try IT...To Eliminate Fumbling With Feed issues.
IF I was going to do it AGAIN, I would aim for 16 different clones in the SOG Style


Also, You CAN take a small piece of tube hose & insert IT into the Air Pumps "Intake"...That will SILENCE the fucking Heavy Duty BUZZING.
That shit gets loud & its on 24/7.

You can put Your ear to the apt. door & its just straight MECHANICAL Buzzing.
for 90 days.

Yeah the whole pump thing goes over my head a little. I'd just get 2 pumps with 8 points on it, job done. What's the quietest air pump you all have experience with. I was looking at the linear air pumps. They work in a different way to the regular hailea pumps

Dude you are a legend I was wondering why my bubbles are uneaven

This Is My Current Setup...2020
I wanted to run Straight COCO...for The 1st time...


This was 10 Days After Rooting...
I was freaking out...The AT600 is a beast.
Santa Cruz Blue Dream & Animal Cookies Circa '09
You can see the 100ft & the Air stone...I transplanted back to DWC 3-4 days later...



This Is 2 Days Later...I knew that DWC & The AT600 would BALLOON these cuts into Almost Light DEP size plants
There is NO WAY to finish 6 buckets in a 4x4 with this type of output...
My housemates Raided This Grow Before I could Flower. $750 in clones...Trashed.


This Is The T5 growth...It looks like any LED on the market Today...
2 - 8 bulb T5s run 864w Vs Most LEDs run 250-400w...2014


This was the real kicker...AKA The birth of BURPLE
I never had My previous plants do this...Even With perfect Ph/Ppm/Ec
That was my 2ft T5 with various nano meters & 10K kelvin...inside a kloner...2013\2014
Today, if I switched Back to T5...I would use Nano Meters, Kelvin, & UV ABC's in 1 fixture.
That was PRIVATE R & D for My Grow Trade Secrets
I THINK it will blow the current LED market OUT of The Water.
DONT TELL ANYBODY!!
If I didnt have the AT600...I would be using 1600w of T5 power

Bro I started with a 3x3 tent...a Shiny NEW CO2 Tank...& 1 bucket.
I didnt know WTF I was doing...
I didnt even have Nutrients..

I have FAILED so much that its INSANE
Its so easy to grow awesome frosty plants These days because People Like Ed Rosenthal & Soma & Dj Short & TomHill have all Paved The way.
Adam Dunn, DnA, Arjan & Franco, ...Karma, Bodhi, Top Dawg
The people I look up to...Are ALL Breeders. or High Profile Testers.
Most of My Mentors are Cannabis Millionaires Now...

At My Peak??? I had 5 tents...5 lights...CO2...1 cloner...A/C & Dehumidifier with 2- 800cfm fans 40+ seed packs
I was seed making & pheno hunting in the same room...
I was having 1 on 1 convo's with actual Breeders...
I had forum friends that had clones by the scores
Most of My Peers are now running 100 plant ...500 plant Metrc Intergrated Mega Grows

I Fucking Burned for this shit Bro...
Now, this whole legal thing...the culture vultures...the BOOF...The Flooded Market...The DANK...The Genetic Soup of HYPER POLY Hybrids
When This Shit Is Legal & everybody has a pound ,,,
I still want to know that I can rely on GOOD people to SAY, HEY RAINBOW GLITTER CANDYLAND #2 (the coloring book CUT),,,is FAF!!! Bro!!
FAF?? Yeah FIRE AS FUCK!!!!

IF anybody REALLY ask...Im just feeding The Streets Right Now.
I Hang Out on a Local Dealer Corner ...buying Weed from The Dope Boys.
I float around My WHOLE city buying Weed On Purpose...Just to see who is Holding & Who Isnt.
I dont even Give a Fuck...I smoke Out ErryBody...
Get Robbed at Gun Point & still be smoking
I travel State to State running thru dispo's & laughing at FuFu
I was in Denver making direct sales for fun...I dont even HUSTLE anymore.
Digi Scale Wah?? Baggies...wha?

Im Going To OKC...
I think OK. is going to be a CLONE Hub.
It Seems Crazy...but I think RANDOM Heirlooms Are going to start Showing Up there
Colorado Is DEAD on Clones
Cali is a Library of Clones
Portland Might Be Clone Central
NY is So DENSE with People....We might see some SPARKS come out of Their Clone Game...NEW UNDERGROUND FIRE. Maybe...
TX is never going Legal...Fuck It.

~Im out

Bubbles uneven because Air stones are crap. Your lucky to get 1 good one out of 4. Its usually the inside wasn't drilled properly ( I think, unless they are cast), with half the pores blocked up from the manufacturing. However they make them, it's not a very good process IMO, and that goes for most brands I've tried.

I don't grow in the house often, but when I do, I have a whole fleet of smaller aquarium pumps, that are virtually noiseless. The cheap walmart kind or whatever. One for each plant site. Its just as cheap to buy multiple smaller air pumps than one or 2 larger ones too.

Outside in my grow trailer rooms though, I use bigger air pumps. I can still hear them in the driveway when I walk past, and even a sheriff one time, lol. Noisy things they are.. No way I will put up with that noise if I grew inside. Not even the large dual diaphragm style pumps that claim to make little noise.

Putting your stones on a looped manifold will help. Having the air come in from both sides will equalize the pressure towards the farthest ones down the line. You don't need to run as much tubing that way either, although just making them the same length will work, you'll have a ton of tubing to deal with. Or you can adjust flow by adding little valves for each stone. Little 1/4 valves are cheaper than running full lengths of tubing to each stone i'm sure.

Better yet, skip all that BS, and get a used medical grade oxygen concentrator of the marketplace, and pump in pure oxygen to a venturi fitting into the feed lines, lol.







Or, drop a HHO on demand fuel cell down in the res, and split the water back into hydrogen and pure oxygen. (I tried and its weak, but fun to play with!)





JK, leave the crazy experiments up to me

Yahoo medical grade air I'd be inhaling it myself. I need a quiet pump. I'm doing it in a shed that's beside a sidewalk, it's also damn quiet here, you'd hear a pin drop especially in the evening when people walk dogs. I'll shop around I know the air curtain things definitely bring humming down alot

check out an aquarium website. get a linear pump. pricey but silent.

These are on sale for $10 a piece on the pet store sites. I would get 8 of them, instead of one big noisy pump.
