I am running 2 gph woodpeckers with 4 ways so each 3 gallon pot receives 2 angled drippersBottom feed reservoir will make things much easier. No need for pumps from each res. Also cheaper to use air for water column mixing in the res.
What kind of emmiters are you running and is there a pressure requirement? as it can make a difference in what I'm thinking.
Do you have height to take advantage of a gravity fed system with solenoids? Only ask casue would be cheap to setup and eliminate issue with pump failure.
What are you running as a control system?
Have you calculated the GPH needs, head pressure, accounted for the water hammering that usually accompanies these setups?
Have a diagram of the layout and where you plan to put your equipment?
Correct bottom feed tank use the weight of the water to supply the pump so if you have adequate sized pipe for the gph no need for a pump from the tanks...I am running 2 gph woodpeckers with 4 ways so each 3 gallon pot receives 2 angled drippers@ .5gph each dripper.
I run 10x 3 gallon pots in a 4x8 tray, they are some hearty plants.
I don’t think I can run a gravity system bc I need to plumb over two doors and then down to each tray.
I have not yet accounted for water hammer yet as I didn’t know if the setup would work and if so then where I would put (water hammer prevention). I was gonna run 1 Hydrawise sprinkler controller 24 zone. But wasn’t sure if that would better than doing 4 Hydrawise 6 zone controllers. Or really how to wire everything properly.
Each reservoir containing different feeds etc.
So if I drill holes and put outlets in the bottom of my reservoirs of each feed then plumb them into the main inlet of the DAB pump I don’t need the other pumps to feed the DAB pump?
Correct bottom feed tank use the weight of the water to supply the pump so if you have adequate sized pipe for the gph no need for a pump from the tanks...
so water hammer can be delt with in a few ways. Cheapest to save on placing arrestors or other solutions in the system would be a delay for the solenoid to close after the power to the pump is cut. Like 1-2sec. That will allow pressure to drop before the solenoid closes and eliminate water hammering. Food for thought.
Sounds like a low pressure system so running the feed line from a manifold to each tray from above will provide a couple of benefits. Meaning pumped up to the ceiling and then down to the tray.
You can eliminate most of the nutrient solution that remains in the lines with some planning using vaccum relief valves at the highest point if not using any form of pressure regulation at the tray manifolds.
So all tanks to the first manifold with a solenoid on the lines from res and then the pump and another manifold after the pump with solenoids to each feed line.Yes it is a low pressure system. In total to give you a better perspective there is 15 total trays in the flower room. I have 5 zones each housing 3 trays each zone. so 5x3=15 .
My dilemma is that not all trays have the same feed schedule as we run each zone perpetually so supply is consistent. I'm trying to figure out how I can run separate feeds to each tray if needed. ie; some strains take longer or shorter than others. So in other words if I had 1 zone with 3 trays running all same strain , it would be different then running 3 separate strains with 3 separate feeding schedules in 1 zone , not to mention still having to plumb the rest of that subline to the rest of the other zones with trays that are receiving that same feed.
Each tray should have a manifold? What would it consist of?
Ideally I want the DAB pump to work with whatever feed is scheduled at the time and push feed to all the zones that need that particular feed #1,2,3, etc and open the trays solenoids to feed each tray.
I know it can be done I feel maybe a checkvalve before each tray manifold ( solenoid etc) to allow water in but if the solenoid door is closed it wont feed that particular one tray and bypass it then moments later after subline is drained out by delay
when the proper feed # is being sent down the subline to that same tray's zone it opens then feeding that tray with its correct feed # and would follow through until the cycle of scheduled feeding is over with....
I can envision it in my mind that this sort of works...but sadly i dont know how it could if it were to be possible.
It may have to do with how the pumps in each feed are wired or timed differently with the hydrawise sprinkler controller im going to purchase.
Just wiring 4 different feed pumps to a common wire to feed the zones doesnt seem possible or if it was that there would need to be some sort of delay trigger to signal each feeds pump to turn off before another feeds pump turns on. 3 flower feeds, 1 veg feed.
I believe a filter should be installed before each feed line leaves the reservoir, and I dont have any ideas for pressure regulation as of yet. Open to any...and all..lol...
Thank you all for your support and assistance in the matter at hand. It greatly aids individuals like myself to achieve goals that are innovative or difficult yet still helps other enthusiasts and community followers to overcome common obstacles that are hindered by lack of knowledge and experiences. Thank you for sharing your trials and errors, and the extra brain power it takes to solve fun puzzles like this.

So all tanks to the first manifold with a solenoid on the lines from res and then the pump and another manifold after the pump with solenoids to each feed line.
So 4 solenoids (1 for each tank just before the input manifold)
Then 5 solenoids ( 1 for each zone after pump and output manifold)
When say zone 2 calls it opens the res solenoid and the corresponding solenoid for the zone and energizes the pump
If this fits the bill then you will put a water hammer arrestor between the pump and output manifold or have the pump shut off 1-2 seconds before the solenoid closes.
If this makes sense can go from there with the rest.
No problem man.You are the man! I believe this has substance! We're working with grease now!
So I believe this will work with just the 1 hydrawise 24 zone sprinkler controller.
I can charge each feed line with the pumps going toward input manifold and having a single plumbed pipe go back into same feed so the water has somewhere to go when the solenoid is not open just recirculates back into feed reservoir. And all 4 pumps can be on relay box timer or separate timers all together.
The water hammer arrestors should go after the first input manifold and after the output manifold. Even though you say turning DAB pump off prior to solenoids closing so pressure in the lines can dissipate? I can time this through hydrawise sprinkler controller?
Would I need a backflow preventer in this application ?
I believe its the wiring of the solenoids after theyve reached the desired zone is whats going to be the biggest puzzle for me. Making sure each one of the trays solenoids are opening and closing to desired feed.
:Aquaman: ty again for all your feedback!
Man you all gonna laugh but I have a tiny ass phone and am crayon doodling skill challenged.what 90? The elbow at the top of the output line up at the top of the wall (basically almost to the roof?) and then down and out to the zones? And that would imply having a manifold after that to each zone of my 5 flower zones and the 6th being the veg line with all the same feed and no need for extra solenoids I believe just the one at the end of the output manifold. I can ball valve zones of the veg so it wont be irrigated. What kind of vacuum relief seal were you talking about? THIS>>> 1" Vacuum Relief Valve?
