Cocodtw equal rings ffs do it for me

I got 1000lph pump.
going to a 19mm feed tube. (2m)
Which tees off to 5 sites fed by 13mm drip rings.

I csnt get equal preassure? Last few dont get as much. First 2 sites grt half litre and other 3 under quarter

No wheres open so hard to go buy atm... What can i do to equal preassure?

I got 50meyers of white 19mm feed tube and 50m of 13m fred tube lol
Im in a 2.4x1.2m tent 5 planta coco dtw

A manifold needs to be built. Water will always take the path of least resistance. You need to run the 19 the full length needed to reach each site. From there, if you're teeing off to them or using a cross, this is where it needs to reduce to 13. Everything needs to be equal.
When you're building it, always keep in your mind that the water needs to be able to fill a manifold first that is larger than the branches going to your sites. Water will want to fill the most open and easiest to flow through areas first. Once it's done that, and pressure builds in that space, then will it decide to start flowing through smaller avenues.

Sobrunning a pipe 19 down the middle teeingto 13 to rings isnt classed as a manifold?
When i do this the first few pots feed. More than the others at end

Airwalker again i love you haha. But confused.

So running a 19mm dowj the middle teed to 13mm rings isnt a manifold?

Im lost to doing this u shud see the octopus o made in my room im laying in the corner curled up crying haha feel like chainsawing the entire grow to. Its atm lol i think im going bald.

I have 5 plants il drop a pic all the disnaces are totaly different. There under a scrogg snd fixed 2 week in flower

Let me just first forewarn you, those 1" return lines are going to royally screw you one day.. your plants aren't large enough yet, but they will be. Come mid flower, root zones will explode and most likely plug 1, 2 , or maybe all of them enough to where your feeding from the pump will just keep filling while nothing drains. Disaster.

Get adjustable valves on each line and adjust down so pressure is up.
Or cap them with smaller outlet so pressure is up.

What do you mean gona screw me? Whats gona block? Oh i get ya nah wil be fine thete away from the pot i csn insoect them daily
That in pic is plants in 20l airpots. Risen 3inch on iws trays and sat in saucers which are plumbed to 19mm pipe which drains to a bucket in the middle.

When i feed to 10% runoff it drains to the tray and when tray gets full it pumps out to a dump bucket i empty.

Just having to hand feed atm. 2 litre in mornin 2 litre at night.

Ive built a manifold with 13mm pipe and i am drilling tight holes.
I have 6mm feed line i am pushing into the holes tightly so the rubber keeps them sealed.

These 6mm feed lines go to my 8mm drip rings

Gona test soon.. Will this work better like u said airealker? Made it big enough so thst all feed lones can be equal.
Its 50cmx140cm 13mm pipe
13mmtees joined with 19mm pipe.
5x 8mm halos 9 holes 2mm
Halos join via 6mm feedline
Complete circuit 2 fill directions

erm....

ummmm.....

that dripring isn't going to water your pot evenly.....

do you know what a TEE is?

Using what i got man allbthe shops are shut.
My cooltube was orderd 3 week ago
And a shit ton of tees elbows etc
Also my halos are in post 2 weeks on amazon prime
And my system was a dtw rhizo system 400 quid but god knows where that is sobi did airpots and dtw as best i could

Course i know what a tee is but ive seen peeps doing a line of emitters line flow and curls dripping so i dont see any problem.

I ran out of black pipe so im using this pvc water pipe dya know howlong it took to heat and bend to circles i csnt evem feelvmy fingers.
Non the less it works but preassures low so think il upgrade to my 2000lph that will pressureise it
Otherwise all dripping equal


Some hos are horse shoenshaped anyway so why it mstter?

might work ok with enough pressure....
i also understand that the distribution manifold is your major concern.

if you have enough pvc laying around, make your manifold loop back to itself. with a tee, lol.
that will provide equal pressure to all pot sites, at least.

I have there all off a circuit fed from the middle
They work just low preassure eg they run 6 of the 9 holes and i csn control stoo start raising them n lowering them. So not enoigh preassure yet

One central pumping point (manifold)...then all feed lines running from the manifold should all be the exact length and have the exact # of fittings, elbows, emitters etc...your flow rates to each will be relatively equal. Otherwise, as mentioned I would incorporate valves that will allow you to adjust the flow of feed to each emitter (ring) separately. Good luck.

My personal experience is when the plants are young, it is nice to hand feed around the rim of the pot. Once roots are established, it doesn't matter how it's distributed on the top of the pot. The water will saturate the whole pot. I use a 1/4" feed line to each pot, no emitter with frequent light dose feedings. I'm in fabric pots with a 14" diameter in 100% coco outdoors for what it's worth.
