Irrigation Controller How-to

Hello Everyone.

I been working on a irrigation controller setup. I have now setup 2x and now ready to build mine and show you how it is done. This may get kinda complicated so please let me know if you have any questions.

This all based on "Hunter style" valves. You see this used for landscaping and yards.

But you do not see for indoor hydroponics often. Why? Because you need some way to control the pump Got it worked out.


why am I doing this?

Well usually you hook a pump up to a timer. And use that to control your irrigation/drip system.

Because most timers minimum setting is 60 seconds/1 minute.

Well this is too long and causes too much waste. Also doesnt work well for young plants (can get overwatered)

The other drawback is it cannot control multiple pumps and resevoirs.

For example: I want to flush one time a week with water.
Or I want to do a flush feed flush method of feeding.

If you look at methods used by commercial greenhouses you will see the water feed water method being used.

This allows you to pre-treat the medium with water before adding food. Therefore reducing the chance of burning the roots.
There is less salt buildup in rockwool and coco therefore reducing the need for flushing.
The drip lines are kept cleaner.
This will also allow you to use organic based food.

You can also program the irrigation controller to do a feed feed feed flush or however you can designs

Ok enough with some of the pros.

Let show how this works and is setup.

I am showing you this to help you save money and to show how to put it together and track down the parts.

If you are only using one res, you can get all the parts at home depot!!

I want to automate feeding and flushing. That is why I am using the Dig 5006-!P irrigation controller.

Also has many features that kick ass and will make things easier.

Ok here is the plan for my setup. This helps you to see the trays, valves, res and irrigation lines. You would change for the number of res's and number of trays you have.

Example of Drip setup. (see pico's tutorial on how to build PVC drip manifolds)
I suggest creating them with the ability to come apart. Make for easier cleaning and transporting.

DIG 5006-IP Irrigation controller. This is a commercial unit. Took me a while to locate it. I originally tried to do this setup with a toro unit from home depot. It works but will only control one master valve. (will explain more about that later)

Model 5006-IP

Application:

* Greenhouses and nursery
* Irrigation, cooling and propagation

Watering Schedules:

Watering schedules can be set according to four different programs:
# Standard watering cycle: 7 day calender
# Cyclical watering cycle: intervals from 1 to 30 days
# Repeat watering cycle: intervals from 1 to 23 hours
# Repeat watering cycle: intervals from 1 to 60 minutes with option to operate in limited time of the day AM or PM
# Repeat watering cycle: from 1 minute to 5 minutes in 1 minute interval
# Repeat watering cycle: from 15 minutes to 45 minutes in 15 minutes interval

Features:

* Independent program start time, run time and day of the week for each valve
* Four button with an integrated liquid crystal display (LCD)
* Easy to read AM/PM clock
* Four start times per day, per valve for a maximum of 24 start times for all valves (irrigation mode)
* Automatic short circuit valve detection isolates the shorted valve and continues irrigation cycle
* Internal circuit board eliminates the need for fuses or a circuit breaker
* Start time stacking prevents hydraulic overload
* Watering durations from 1 second up to 12 hours in 1 second increments
* 7 day customized programming schedule or intervals from 1 to 30 days
* Rain delay up to 30 days with auto restart
* Large clear display for easy programming
* Can operate two valves at the same time
* Waiting mode for third and fourth valves
* Three modes: automatic, semi automatic and manual
* One 9v alkaline battery backup to retain program memory during a power outage
* Digital display, low battery indicator
* Master valve remote pump start circuit
* Default program: after prolonged power interruption each station will operate for 10 minutes
* Can be programed under backup battery power without AC power connection
* Can be used with a rain sensor

I am using 2 60 gallon res. I measured the distance between them in order to build a manifold that houses the valves. I also added a threaded junction so I could use lids on the resevoirs.
42585res.jpg

There is one master valve for each res, then a valve for each tray/manifold that gets waterered/fed.

Ok here is the 2 res with manifold pumps, ready for wiring
42585res_done.jpg


here is a pump start relay. Basically a box with a relay inside. this will allwos the irrigation controller to turn on your pond pumps.

This is where it becomes confusing if you were to try and but the parts at landscape store. Well know you know what to ask for now. If your a electrical whiz I am sure you could build this for cheaper.

42585pump_start.jpg


I took a extension cord and cut it in half. I then wired both ends into the pump start relay. The male end plugs into the wall. This supplies power to the relay. The female end comes out of the relay and that is where you attach your pond pumps. There is also a wire you will run to the irrigation controller. That is the white wire.
42585pump_start_done-thumb.jpg


Here is the wiring supplies I needed
42585wiring.jpg
.

Now one wire runs from each valve to the controller.

Then there is a master wire that completes the loop.

here is where the wires attach
42585dig.jpg


Now you program the controller, plug in the pumps.

Then hook up the lines from the valves to the manifolds.

I used barbed fitting to run flexible line to the trays. The ultimate would be to run the 3/4" piping as close as you can get.

I used 1800 GPH pumps, I prefer the 2400 for the distance I am going from res to trays. That really sprays out the water from the drippers and provides even saturation.

Ready to run!

I am in the middle of some things. Will take some more pics to show the whole thing in action. (and the lines all plumbed up)

Whew that was some work, going to take a break and then see what to add.

More info on valves.

The Home depot model of irrigation controller is the TORO ECXTRA. it has expandable zones and can be programmed on your computer.

It starts at 39.99 for the 4 zone models. Where the DIg retails for around 80 and will probably have to order.

Basically in irrigation terminology each valve is a zone.

I have 2 master valves then 4 zones.

I am not a irrigation expert so excuse me if I mis-quote. Just trying to share.


Hope this makes sense?

Any questions?

-Peace

Wow...now that's impressive! You can go away for as long as your resevoirs will last.

When you suggest creating the PVC manifold with the ability to come apart, you mean without the PVC glue? The pressure from the pumps does not cause any leaks?

Can't wait to see the rest of the picks

Thanks, Glad it make sense. I am trying to seperate each system of the grow room to make it more reliable.

If you have Float Valves on the res and auto ph/dosing then you could have automation.

I have a float valve on my water res. The food res then gets filled up 1x a week. (Since I have to add nutes ph etc)

I then can spend my time lollypopping, cleaning, taking care of moms etc. And have a life once in a while!!

Yes, I mean without any glue on the fittings. I was able to make new manifold with minimal glue.

There are fittings that have a o-ring if they did leak. (I didnt use em they were more expensive)

I used telfon tape and works great.

They even make plugs that screw in. That way you have a expandable customizable manifold. (That you can also take apart and clean)

another manifold TiP.

I designed my new manifold to sit right in the ridge of the Tray. Then I drilled holed and used zip ties to hold it in place. V1 manifolds sat on top of trays.

I also designed it to accomodate 24 12 8 or 6 containers.
You want everything same length for even flow

Pics of manifold v2.

Screw in ends. (only part that is glued is the center pipe to the threaded fittings)

Love it and I love the pic with the bong in the back ground ... Id like to do that ...At the moment I have the same size tank feeding to a 50 liter resivour and have a small pump on a auto timmer I can go away and not look at mine for 2 weeks with out a problem and know that my watering is all done and on time

Looks solid, Yukino. I have an irrigation controller in my garage that controlls six zones around the house. I ran one of the zones into my room, so I water with that (manual on/off, as my controller is a toro, minimum 1 min on) and feed by hand. How does it accomodate different sized pots? Maybe thats why you don't glue the manifold together, so you can add/subtract length of the cpvc?

Your setup looks boss though...thanks for posting the how-to. Next run, when I narrow it down to one or two strains I may try something like this. :joint:

Thanks. Good idea to use one of your outdoor zones. Too bad it cant feed too :)


yes different sized pots are fine. As long as you have even drip lines it will work fine. (I use a strong pump 1800GPH, if you use a weaker pump may be an issue with flow being uneven.)

I didnt glue the pvc together because then I have built a big manifold.

Then It is more difficult to clean or take apart.

Main reason, but then I can easily change the center section if I change tray or plant #'s

Cool watering system. Nice design!
Rain Bird makes a real nice Commercial unit (not found at lows or hd but can be found on fleabay in the 100 to 300 range or commercial irrigation warehouses) capable of running in seconds or running a total time broken down into cycle/soak sessions. To make it run in seconds you would set it to run 1 minute then tell it to water at say 25% so you water for 15 seconds or 25% of a minute, 10% would be 6 seconds. Same for 12hr or 18hr light cycles. Set to water for 6hrs at 200% so it will run the light for 12hrs. For co2 I cycle/soak, I inject for a total 6hrs on in 15min on and 15min off sessions so it last a total of 12hrs. I use them to control lights and timed co2 everyday and a watering system when I have to go out of town. The clocks are digital with battery backup so even if the power goes out the start times always stay the same.
Stay safe when mixing water and electricity.

Peace

Great Thread - Great resource!

Great Thread - Great resource!

Thank You!!!

I have been searching for this thread!!!

I have been playing around with 24v irrigation solenoids and an Orbit 6 station sprinkler controller (Lowes). The flexibility is great and for my needs it is pretty stealth enhancing as I have a "secret" area that I try to keep closed and the sprinkler system helps me do that. Monitoring is so easy these days with cameras and temp/humidity units accessability.

I also have used an ART-DNe timer for the nute tanks and it is awsome!!!!



!!!!The ART-DNe is NOT cheap!!! (~$80 ea)

The really cool thing with irrigation controllers is the different stations and flexibility of programing. Not to mention the great price and availability . (compared to anything hydro specific)


Great thanks for starting this needed thread !!!
