Absorbers Bell Syphon Grow

Hello all ,
my name is Absorber or Abe for short .
I have a custom designed grow with proven results .
It uses a 3d printed bell syphon to flood and drain the four 15ltr buckets in each tent , i have two 4ft² tents with 1ft clone/mother section on the end making the tent sizes 4ft x 5ft in total each.
I run 1000w phlizon lights @480w tops ,i have a 3d printed light lifter to raise and lower the light as its to difficult with a scrog net and tent full of plants .
I have a 2 zone controller for the tents and a common 250mm extraction fan and carbon filter fitted under the floor and you can see the 3d printed purple Y piece with 3d printed electric shutters controlling air flow from each tent via a humidity sensor . The fan runs at half speed when 1 tent calls for fan ( regardless of which tent) and ramps up to full speed when second tent calls for fan .
I run cyco nutrients and calmag
Thats it no boosters or anyting else apart from ph buffers .
I have a chiller on the resevoir.
Ive just converted the second tent to a bell syphon settup as it out performed the SIP pots i had in there as a comparison .

Warning some potty language in video's

Like your style, Abe, pulling up a chair. What ya got growing there?

Ill have to look closer on the setup before i can get my head around it and start my incessant questions, lol. Very interesting. Ive done non weed sips and loved it.

Nothing currently in there but im going to take some cuttings off this Green Crack from Canuk seeds and they will go in if they make it .
The white pipe you can see on the top of the resevoir has the bell syphon in it it has pipes on the side connected to the buckets .
Any questions you may have fire away:cool:

More like a flood and drain in buckets without a timer on pump

So it floods and and empties, net pot and then free hanging roots? So roots get water /air/water/air constantly? Am i getting this right?

Thats rather knarly! Only thing that would worry me is roots in the drain.

Yes the whole bucket fills and empties continuosly and water fills from top .
And yes at about mid grow i can see the drainage slows so i pull roots back from drain pipes ,its not hard to do and only has to be done once but im working on a solutuon for that ,that will be to come in future post :cool:

"What ya got growing there?"

That was obi wan kush from canuk seeds next to can and cherry pie in foreground to the right .
I had green crack ,acapulco gold ,obi wan kush and cherry pie in that tent last grow.

Dont know those, so no real point of reference.

How long does it take between one "flush" and another approximately? Edit: answered in the video


Im pretty sure that if i made that system id try to work in some water vortexing or something. Im a born believer in all things weird and freaky - or at least i have a need to see things for myself, do my own research.
Vortexed water has been suggested to be special, differently structured with some pretty weird properties. There is much woo and bullshit about this out there but seems to be some support- the airlift vortex is supposed to be the highest water O2 saturation of any method. I just know i wouldnt be able to stop myself from going all in on magnets and shit if i had situation where id constantly drain water from my buckets, lol.

The results i got from this tent last time where really good and i couldnt get to the back to do much training because of scrog net and only being able to access the tent from one side ,so i could have harvested more but i have no complaints it far exceded my expectations i ended up with the biggest densest buds i had ever grown. This whole grow style was my experiment from things i had learnt over my 30+ years of growing .
And i tried to reduce consumables and keep it simple but also doing what the plants like .
The second run will be the confirmation

I think any system which supports frequent frequent watering cycles, which also creates an intake of air in the rootzone, is going to work great. It solves the dissolved oxygen problem, with having to cool your res, in order to provide oxygen for the roots. I mean why would one go thru that hassle in order to create a very low level of O2 in the water, when the air is full of it? Youve done it very elegantly with no media, and low power pump. Dutch buckets does it in the opposite way, with timered high power pump that floods the bucket and then the pump stops and lets the water return to the res, keeping a little bit in a mini res on the bottom.

Theres another system which is based on similar ideas of frequent watering of media: the PPK by Delta9/greyfader on icmag.
Top watered media, taking advantage of some very clever hydrodynamic effects to remove excessive water retention from the media. Ive sort of validated some of it by by doing some tests on the tailpipe designed pots: changing the shape of the pot made our coco retain only 2/3 of the water of a standard pot and thats still very tweakable to get even less. Im not looking to set that up for a while but i hope to do another test soon: using these modified pots i wanna add 50% media while maintaining same watering schedule, as a first try out. Bigger roots, bigger fruits. But im dependant on my growbuddy giving me a go ahead, hes the final decider and often instinctively in the no camp of all that i try to do; its been our dynamic for a long time even though anything ive been able to push thru has always been beneficial.

Its all fun and games you sound like a fellow tinkerer and inventor when are you getting a 3d printer for prototyping;):D

Its not as high up on my list as some custom led strips im in looking at making, spectrometer and thc tester but its there.
I know @cobshopgrow is another 3d printing diy crack, cobby have a look at this one: I honestly think its hydro with not chiller, no aeration and only a small basic pump.

Edit: i need to get back into the computer related stuff of tinkering, i keep on meaning to learn more of home assistant, esp32 and raspi but i still cant find a good place were to start. Ive just settled into the idea that it will magically come one day or ill just find that perfect place where to start where it takes you directly to the stuff i need. I got a programming background but that was over 20 years ago.

Doesnt help that i dont have access to the grow unless i do a 90min trip. Hard to program automation when i cant actually see it work.

3d printing is there somewhere but not a first priority. But yes, with some ready designs i could get it printed at one of the makers clubs in town.

Github has lots of projects people have done ,im a sparky by trade and i have dabled with arduino a bit and writen some basic codes to achieve what i needed , i have other projects over my coding skill set sitting on the shelf .
One day
