I have an 8 bucket Waterfarm......
    the water in the res  always gets stagnant from not going anywhere.
  the drip heads only take the water from the buckets.
  If you could make it so the water from the res is pumped into the buckets it would work better than mine :thumbup:
  also make sure you have a known female and clone it and put the clones into the hydro system.  I put seedlings in mine and like 5 turned out to be males.
  But yeah I have been thinking about giving it a go again with it.

I would never put a seed in a system, only known females. In response to the first part of your post...

The res pump pumps water to the controller, then the controller lets the water freely move to the 12 buckets using gravity. Once that is over the controller pumps the water back into the res pulling the water out of the 12 buckets.

Updated with pictures. Buckets should be here tomorrow.

In the mean time become familiar with this. It is the schematic for the controller.

Got the rest of the parts tonight and the timer came Friday. Buckets will be here tomorrow for sure.

Hope your ready.


Edit: I hooked all the female connectors and jumper wire to all the parts except the float switches because they still need to be put through the 90 elbow then through the bucket (controller).

I also destroyed my project enclosure trying to drill it. I knew this would happen so its not a problem (Im not good with a drill.) Im going to be getting a new one tomorrow and drawing circles what I want cut out and taking it to an amish guy down the road (He is very good with a drill).

Also... the float switches I got arent 1/2" threads. Because of this I have to think of a way to secure them into the 1/2" elbow making them water proof. I was thinking of filling the elbow with silicon but everytime I mess with that stuff I ruin at least 3 pairs of socks, some shirts and a sheet. We'll see what happens

Well I glued the float switches to the 90s tonight.


I wrapped 2 rubberband hair ties around the threads. I then put gorilla glue on them and pushed it into the 90. The rubberbands helped to hold it in place while the glue settled.

After about 20 mins of holding the float switch in the 90, I filled the opposit end with gorilla glue and let it dry. Now I have a really really strong hold that should be water proof.

*Careful when using gorilla glue. I got it on my hands thinking it was like super glue... its worse. Water does NOT wash it off, only paint thinner. Gorilla glue also expands so use sparingly.

Tonight I drilled the holes for all the buckets and connected everything to make sure it all fits well. It ended up taking forever however since I wanted to do this a few days ago and I couldnt wait long enough for the drill to charge. I did this all in about 10 mins bursts.

I looked again today for a 13/16 spade but but couldnt find one. I asked a friend of mine and we looked in his garage. We couldnt find the one but I looked on the floor to the right and there was a rusty one with a broken tip. I picked it up and lucky me... 13/16 :smile: I had to predrill all the big buckets first since the tip was shot.

First I made a template for the 3.2 gal buckets.


Then I placed it on the bottom of the buckets and drilled. Im not sure what size bit it was. but it fit nicely in the template.


Then I drilled the big buckets that hold the 3.2 gal buckets and added the grommet.


Cut 9 pieces of hose 18" each


Hooked it up. (The hose needs to be on the T more, but I just hooked it up to see if it fit right. Also, push the T in just until it pokes through the other side on the grommet.)

I realize today that I do not have a black bucket to use as the controller. I found a white one however...

Here is a birds eye view of the controller.


You will want to drill your holes exactly like I have.

These holes are 1.5" apart from one another and 1" from the bottom. These 3 lines are whats used to hook your controller to the 12 pots


Directly opposite of that, is the reservoir water in and reservoir water return. The bottom line is 1" from the bottom and I placed the top one in the center of the top two ribs.



Now inbetween the first set we drilled and the second set but more towards the second... Drill for the float switch.

The bottom left hole is 3 1/2" from the bottom. The bottom right hole is 3 3/4" from the bottom and 2" to the side of the first hole.

The top two holes are placed directly above the others. You will want to drill your top holes AT LEAST 4" from the top since the float switch + 90 = 3" and you want a minimum of 1" at the top where the water wont go.


You will want to place the bottom switches facing down and the top switches facing up.



Wiring comming soon :smile:

Ok well tonight I was eager to start the controller box. I started by measuring the outlet and the timer. Both were the size that I didnt have bits for. So I drilled smaller and used a file to file the holes bigger....

A perfect fit :wink:


I temporarily have wire holding the timer in until I can get some screws.



Here is the inside. I should have just enough room for all the wires and the 2 relays.


I also drilled 2 holes on the bottom. One for the electrical cord and one for the controller buckets float switches to go through. Ive decided to do that rather then attatch the controller box to the actual bucket. That way its more accessible.

I also realized I dont have any wire since I used it all hooking the shit up for fun before I got the box. Ill have to go get some. I think Im going to go with 22 guage since that what size the float switch wire is.

From here feed your float switch wires through the other hole in the bottom of the box.



High Level-High refers to the top switches, highest switch.
High Level-Low refers to the top switches, lowest switch.
Low Level-High refers to the bottom switches, highest switch.
Low Level-Low refers to the bottom switches, lowest switch.


Join your HLH and your HLL switches by connecting one wire from each with a female connector. Attatch a female connector to the other wire from the HLH switch. Then connect 2 pieces of wires with female connectors to the other wire from the HLL switch.


Join your LLH and your LLL switches by connecting one wire from each with a female connector. Attatch a female connector to the other wire from the LLH switch. Then connect 2 pieces of wires with female connectors to the other wire from the LLL switch.

From left to right: HLH HLL


Relay B spot #3. Relay B spot #7. Relay B spot #6. Relay B spot #5. Timer spot #3


From left to right: LLH LLL


Relay A spot #3. Relay A spot #7. Relay A spot #6. Relay A spot #5. Timer spot #4

Take the green wire from the power cord and the green wires from the outlets and wire nut them together.

Now you are here.


Take the black wire from the power cord and attatch one wire with a female connector. Attatch another female connector to the end of the wire.


Now connect thoes to Timer spot #1 and #5.

Take the white wire from the power cord and attatch 3 wires using 3 female connectors leave the last one without a female connector.


Connect thoes to Timer spot #2. Relay A spot #8. Relay B spot #8. Wire nut the one without a female end to the white wires on the outlets.

Now connect a female connector to each of the black wires on the outlets. Connect one to Relay A spot #4. and the other to Relay B spot #4

The controller is complete.

* I had to switch the female ends in the previous picture with these ones because the red ones had a too small of a hole and the wires kept comming out.


The end result.






*note When I ran the test earlier, it filled but did not drain. I rewired the controller box 3 times and screwed everything up. After ruining all of my nice covered female connectors, I rewired it and gave it another test.

It still didnt work.

I switched the floats around on the bottom float switches. Still didn't work right. Switched the floats around on the top switched. Now it worked but it was backwards. I then switched the outlets that I had the pumps plugged into. This finally corrected all the problems.

Explanation of whats happening.

Timer turns on
Power is now on pin 3 of timer..which is connected to pin 6 of Relay B
When the relay is on..6 & 4 make and the pump is powered..
Relay comes on because the High Low Level (HLL) switch also powered by the timer is made..(bucket is empty)..and powers pin 7(coil)
At the same time a holding circuit is created by timer power on pin 5 making with pin 3 through the (HLH) switch to the relay coil pin 7.
This means now you can open the HLL now because the HLH now has control of the relay and now powers pin 7

Water fills
Buckets fill untill it trips the HLH. Contacts open and pin 7 loses power. The relay shuts off, and pump stops filling
(Here is why two switches) now say the water level drops a bit and timer is still on.
the pump would surge on and off each time the HLH bobbed just a little.
With this circuit, for the pump to come back on, the water has to drop below the HLL before the pump will come back on.
This spacing between the two switches creates a hysteresis
The HLH can bob all it wants, it has no power once the relay went off because 3 & 5 opened. The HLL has to start the holding circuit again to get HLH power.
If you have ever used a large power tool or machinery that has a separate "Start" & "Stop" buttons..it's the same thing.
Once you hit "stop" it won't start again no matter how many times you push "stop" and vice-verse. Start starts, Stop stops
Basically the HLL is the Start Button, HLH is the stop.

Timer turns off
Power now on pin 4 of timer. Switches LLH & LLL are made because they are upside down and floating (away from the C clip) Bucket is full
Relay A turns on, 6 & 4 make drain pump power, and 3 & 5 make
and same holding circuit created on Relay A as on B. LLH is the start, LLL is the Stop.

Bucket is empty
Now power will remain on the Drain circuit as long as the timer is off.
So if the buckets are slow to drain and fills the control bucket till it reaches the LLH trip point again..the drain pump will cycle back on
and run till the LLL shuts it off again. Automatically keeping the system drained.

:thumbup:


I've been working on this since around 1PM and now its 7AM. I will run a few more tests when I wake up. Ive having a drain/fill problem. Nothing major, I think its due to the hose I got. It's not flexible at all and I think thats creating a kink in the systems ability to fill and drain evenly.
Oh yeah...I got water everywhere too. If your system isn't working... FLIP YOUR FLOATS FIRST! haha

I had to use a 76 gallon res instead of a 55 gallon. The 76 gallons holds just the right amount.

Both the reservoir pump and the controller pump hoses need to have a small hole put in them and the small 90° barbs inserted. Do this on the hoses right before the leave the reservoir.

* This is so the hoses do not syphon the water out of the reservoir and controller.

Well the system is working. I know now why 3.2 gallon in a 3.2 gallon should be used instead of a 3.2 in a 5 gallon. The water in the 3.2 gallon bucket only came up about 2". I dont know if this will be sufficient for getting the roots wet. I suppose if you use an aero cloner and have long roots to start then you will be ok.


Well, I guess I'll be making an areoponics cloner.... pictorial comming soon. :thumbup:
