One of the biggest problems with the bell siphons is to get them to start and stop properly. Many people will build a bed and put their siphon in it while there is no media and get it to work. Then once the media is added it will magically stop working because the water level raises much faster even though the fill rate is still the same. Then as the roots start to fill in the bed it will continue to affect the rate the water level rises. Making it even more picky, the drain rate is even more difficult to deal with since the media and roots act like a sponge and as the bed gets nearly empty, the water that gets near the siphon really slows down and it make it difficult for the siphon to break. May times the siphon goes in to "limbo" where it starts to suck up a little air which slows down the siphon rate, the water level goes back up again, the siphon speeds up, then starts to suck air again and it becomes a vicious cycle. On my designs I added the cup on the button over the snorkel which eliminated that problem which acts as a "Schmitt trigger" (for those of you who are familiar with electronic terms!). So basically, make sure the siphon is capable of working at different flow rates. One design option, which would add a lot of complexity to the design, would be to make it modular so you could add maybe 20mm chunks in the neck area so that a user could stack the siphon to meet their own height requirements. Probably would be difficult to since you're dealing with sealing the center standpipe, the bell, and the snorkel. Maybe some kind of snap together with a silicone seal. I use Rustoleum clear enamel to seal my siphons...it soaks right into the layers and makes a great seal. Keep up the good work! 👍
Everything here is what you need to consider, lol. I was getting ready to write an essay about it and then, (bige)low and behold, Rob beat me to the punch. Hope all is well at your farm Rob. Love your videos.
What a collaboration, you and Rob I bought a 3d printer just to try your 3d parts. And this bell siphon will be the first on the list to try. Have a month to wait on the printer.
Go get em Hooch! Massive congrats for being able to live off your passion! Not something that everyone can say. So proud of all your growth since you started. Seeing your innovation and consideration of communities and their access is (sadly) not widespread. So glad I can support you on patreon in my own little way. Can't wait till I graduate and earn the big bucks so I can go up tiers!
Would it be possible to have the print file be adjustable? Maybe something like the user inputs total height of the syphon & the middle section is adjusted to accommodate the desired overall height...?
First off Kudos. The threaded nipple design is a great idea and a time saver for sure. Now the suggestion: * How about a 3D set of standardized nipple and thread sets in both metric and imperial? That way those of use doing 3D design work can work with a know set of usable and interchangeable threads. Doing so will make future designs more modular. Look forward to the plant cell effort.
Bell syphon can definitely be used to flood and drain a grow bed into the reservoir - essentially having the nitrate rich fluid before passing into an NFT or other float system
Hi Hoocho. Love the work you do experimenting and developing/tweaking various hydroponic grow methods. Kudos mate! Re sizes of Bell Siphons - most grows suited to flood and drain at depths where bell siphons become relevant (bigger than flood and drain table style) are going to need media depths of 300/400/500mm with media above the flood line of 50 to 100mm. Size of Bell Siphons therefore need to able to accommodate 200mm ad 250mm activations for >=300mm grow beds, 300mm and 350mm activations for >=400mm grow beds and, 400mm and 450mm activations for >=500mm growbeds. I am so looking forward to including a 3D printer in my next grow site expansion, you have inspired me! Outlet needs to be min 19mm, preferably 25mm diam - input 13mm needs min 19mm outlet; input 19mm needs min 25mm outlet. Input larger than 25mm would be insanity requiring a custom build🤪. How can the internals of this bell siphon be cleaned? just a thought. Keep up the great work.
actually i have used a 3d printed bell siphon for a couple years now. in a timer run flood drain for potatoes that worked remarkably well and i get great harvest. The roots lay across a support net the potatoes sit in a net cup ad the roots go down and are across the netting the system floods to that area just below the pot then drains. btw i used PETG with a .1 layer thickness and slightly slower print speed with fan speed reduced and have had no water impregnation through the surface of petg
Make the multi purpose bulk head at a 3/4 garden hose inner diamter to ba able to use a hose "Flat rubber o ring " to seal from thr inner tank side . This allows for a seal with out silicone and have access to cheap garden hose o rings .
i would love to get on that i can print for my grow beds that already have bulk heads installed in them. or a copy of your f360 file to edit myself. looks great fo far
What is the tested min and max flowrate to start and break the siphon? Is there enough hand clearance around the shroud to clear any roots ingress or obstruction? It's a good design but I'm so used to just using a 20mm poly riser cut in half with 32mm blue line as the expansion collar which can be slid up or down as height adjustable then 50mm PVC bell...breaks no problem without a snorkel. I have slide show of my Aquaponic system build you can see how I made my bell siphons.
Wonderful! I'd say, from the US, maybe 8, 10, and 12 inches for the siphon. Also, it would be lovely (and much more difficult, sorry) if it could be modified in some way to act as an *external* siphon to save bed space and keep the worst of the roots away. Not even sure how you'd do that...but you're far smarter than me about such things, so if you could figure it out, it would be marvelous.
Hi Hoocho. Have you tried TPU for the bell syphon? It is harder to print but super strong and flexible. My prints come out 100% air tight so you wouldn't need to spray them to stop air leaks. Because it's flexible you might have to experiment / modify your design. I do think it's worth a look. 🙂
(havent finished watching the video) you could make the shrouds inner diameter compatible with ordinary plumbing pipe (the diameter of pipe that rob uses for example) and put a lip. So the pipe could just slide into the shroud (as it normally would with couplings between two pipes) and then you can have a bottom that has fiddly bits and a lid that has a fiddly bits and the user can find and cut the pipe into the length they need. That maybe requires different kinds of Inner diameter shrouds, also I guess people will have different kinds of media so the size of the holes in the shroud might also be needed to taken into consideration. Good luck and thank you for your effort.
i cant think of anyone else to ask (which means you are kind of the authority on this planet) this.. of all the kinds of hydroponics youve done which would you say is the best for growing weed? im thinking dwc, but aeroponics and fogponics both seem like they could be really effective provided you could get proper net cups to support a full grown plant. as for this video.. watch out for clear coat, i do lots of models (mostly bandai but also knock offs) and theres some combinations of clear coat and different kinds of plastic that make the material VERY brittle. nothing worse than sinking over 100 hours in to a model building, scribing, modifying, painting, getting all the decals put on, and then clear coating only to have a piece break when you go to pose it to put it on the shelf.
Hi there, thank you for brilliant content. I would like to see a Bell Siphon that floods to a height of 20cm and fits a 20mm PVC pipe as outlet. Loving your content here is South Africa
wow i stoped the video early, love your videos, keep your in hydroponics, aquaponics is way more simple, you don;t need a 3d printer, wow what do i say, keep it simple... dont cross the line with 3d printers.. ibc can be converter to grow all mediums without a 3d printer
Given that the neck of the siphon is pretty much exactly the same the whole way up and down, and it's just the base and the head of the siphon that have any complexity, why not just make it have a riser-fitting? That way a single print can be adjustable and you just use silicon to seal the joins?
Maybe try 100% infill? The printing process itself introduces micro cracks to the surface. It's very difficult for a raw print to be water tight. I'd suggest to look for a proper coating and treat the parts afterwards. In low temperature environments you can use bees wax. In any case, thank you for all of this work. We need more people experimenting and solving these kinds of problems 💖🫂
interesting love it! Would love to test on my new 300x300x340 bed. New to printing myself but long time into aquaponics and hydro. Could you not skip the paint and put them in a container over a bed of acetone since after maybe 1 hour it will make the layer lines vanish tho to long can start melting the print. look into methods of making print look like resin since the fumes mold the external it may just seal so only a idea :) Ps with Simplify3d i can just change it to suit size before print anyway to run deeper beds or in mini systems. Great Job!
Well done hoocho, but is that siphon draining quick enough? You are going to have to test it in a chop and flip bed which has way more water than a bucket
Great job on the siphon! Making one is not an easy endeavor, I have been working on one for years at this point haha Have your tried your siphon in a bigger container? I think that if you have a bigger reservoir, you will need to have a pump minimum flow rate. if you are planning on making this available to people, I think that some will face this issue and therefore it would be a good idea to inform them about a potential minimum pump flow rate requirement :)
crazy I designed a bulkhead fitting almost the same like 3 days ago but it takes an o-ring instead of the silicone and I used a 13mm hose ridge instead of a quick connect, great minds! I am interested to know how you designed the quick connect section, is it part of fusion360 or did you come up with it yourself
Hey Hoocho, I've been looking for a 3d print design that allows you to connect a 2inch and/or 3inch pvc pipe to a container, similar to the bulkheads sold by current culture (For a RDWC system using 2 or 3 inch pvc pipes). If you can make such a design I will support your Patreon 🤣
1:05 Buddy, you're a boy, make a big noise Playing in the street, gonna be a big man someday You got mud on your face, you big disgrace Kicking your can all over the place, singin' We will, we will rock you We will, we will rock you
for the bell sipion just be careful with the spray I don't know much about what you've used but its important its food safe and non toxic to fish, some types of fish are very sensitive to sealants.
If you are asking people to offer free help to develop other versions, will you be posting the 3d files for free? (Many people doing hydroponics are doing so to save money to afford drugs for the disabled, it's not an luxury technology.)
3D printing IS a luxury technology however. If someone can afford a 3D printer they can afford a Patreon subscription. The money that I make on Patreon funds R&D of new designs. I offer them to patrons for $3 USD. For access to all the designs. It's a good deal.
I see your still making videos for your 3d printer boys ..... Do you honestly think that you have120k people want to see another video about 3d printing . Probably why your videos have so few views compared to most you tubers of a similar subscription base. I dont care how many Patreon you have with printers ... most of us cant be bothered even watching your videos

OMG. This is why I need an Ender 3 S1 Pro. Great job. 🤗🤗🤗
7:45 😮
But on a serious note, so excited to see you working with Plants In Jars on plant tissue culturing. And your bulkhead fitting is brilliant
Make the multi purpose bulk head at a 3/4 garden hose inner diamter to ba able to use a hose "Flat rubber o ring " to seal from thr inner tank side . This allows for a seal with out silicone and have access to cheap garden hose o rings .
For the quick disconnect bulkhead fitting, why not use TPU filament and make a washer to seal it instead of silicone?
Or use an o-ring
TPU sucks up water like a sponge
Great video as always.
Love this video.
Yes!!
i would love to get on that i can print for my grow beds that already have bulk heads installed in them. or a copy of your f360 file to edit myself. looks great fo far

Can U make one to fit the commercially available bato buckets ?
HOOCH! what type of quick connect hose fittings do you use? do they break or leak or seem to hold up over time?

any updates on the hooch bucket becoming available to buy?
Want one
Would work great for a flood and drain system
