Fertilise your garden with a hose and a Venturi Siphon

** Update ** I have just release an updated video to this one: • Fertilise your garden ...
I use a Venturi Siphon to water my raised beds. This allows me to mix in my liquid fertiliser with the tap water coming out of my hose pipe. This is a video to show you how I do it
You can buy the siphon kit on Amazon: geni.us/venturi...
Or ebay in the UK: goo.gl/x6Ab4Z
Or internationally you can get it off Banggood (a little cheaper too, but takes a couple of weeks to get to you): goo.gl/9RBReb
Don't forget that you need the connectors for the ends of the siphon to connect to your tap system too: geni.us/hozeloc...

I tried using this principle today on a baseball field. I used various fittings from the hardware store… utter failure 😣. Now I know what to do! Thank You for the video!!!

[@TheAnswerworld-et6ze]

Very helpful, thank you. God bless you and your family

[@gonnahavemesomefun]

Any ideas how to calculate the volume of fertiliser to put in the bottle when using a Venturi? I have a fertiliser that suggests 15ml in 5ltrs of water, how does this translate to a sprinkler coming from mains water? Thanks for a great video introducing me to the Venturi 👍

[@wanda04g]

Thank you!! All the other set ups seem so complicated, thanks for the simplicity!

[@ChilliChump]

Its a pleasure. It really is an easy way to do it!

[@Leblueskee]

If you were to have a hand sprayer at the end essentially stopping the flow would it push water back into the chemical jug?

[@ChilliChump]

Yeah, too much back pressure

[@gekarekides]

Thanks a lot. Very simple explanation.

[@120ohm]

Wait, them three beds were going to take "ages" to fertilize with a watering can??????

[@USMC-Sniper-0137]

That would be great for a 55 gallon drum

[@waltraudterheide3300]

Hi i got a question. If got the same but not wat to work. In the side connection with the small suck hose there is a little spring a ball and a plastic flat ring in it. Can you tell me in what seqence this must come in there? Is it first the ball then the spring and then the ring? Or must it be in a different way?? Or did i lose parts?? Thanks in advance from Germany Friendly regards André

[@DouglasDeVries]

Where can I buy such a venturi siphon in South Africa?

[@cannerbernerd1836]

Seaweed/kelp lasts longer if you keep it in the fridge and use all you mix in one go.

[@kootenayboy]

Just to point out the obvious, when using seaweed your mix raito doesn't even have to be close to accurate but if you're using a salt fertilizer like 20-20-20 etc you will need to be dead on and not use the time to empty the bottle method because that has a lot of variables like pressure and flow rate of your garden hose etc. It would have been nice to see more on how you came to your end calculations on the ratio and mix etc

[@ChilliChump]

You are absolutely right, best to be careful on ratios on some fertilisers. I got to my ratios by running the tap through the Venturi into a large water container. Once the Venturi siphon emptied the smaller mix bottle I measure how much water had gone through the system into the big container and calculated the ratio. You are right though I should have showed my method on camera to help people out. When I originally did the video it was just to show the concept, and it is always tough when making these videos to figure out how much detail people want to see! Thank you for your comment!

[@Tom-Ato]

Def a good point to bring up when it comes to dilution ratios for tank/pump sprayers and foliar feeding; however, I'd say that this video highlights a delivery method (regardless of total water usage) for a *finite fertilizer solution across a known area-- hence the oscillating sprinkler adjusted for garden plot coverage. This would be similar to fertilizer recommendations given in Pounds per Square Foot. Plus, I sure hope anyone spraying fertilizers at 20-20-20 should already know exactly what they're doing instead of relying on online videos, blogs, and pinterest.

[@elliottdebell7783]

Do you think this would work if I just want to syphon air into the line like a bubbler to oxygenate the water

[@ChilliChump]

I am not sure if that would work with this particular one. But I have seen something similar that does what you need (introducing air)

[@barnabus06]

I have the same kit, got it after seeing your video. But it does not 'pull' anything from the bottle (which does have a little air hole) Anywhere I can get info on how to make it work eg shorten the suction pipe, pressure requirements etc?

[@ChilliChump]

+Nigel Mackay I had to fiddle with it a bit. Try change the pressure from the tap (open and close the tap). Make sure the adjustable bit on the siphon is fully opened. One you see it sucjibg the liquid, you can close the tap on the siphon off to where you want it. I found that when you use the siphon with low pressure or with the tap on the siphon closed too much then there are bubbles at the Venturi siphon part that stop the flow from happening. Took me a couple times before I "got" what it was doing

[@RAMKUMAR-mb3hc]

I tried , before to start lift the siphon allow water flow through the siphon from inlet, that way air would be removed . Then just dip it. It worked for me. To let the water flow through the siphon I had a ball valve in the outlet which I close for a while until I remove the air inside

[@prosafety6255]

I have that same siphon but when I connect it to a sprinkler nothing come out of the siphon. Help please.

[@ChilliChump]

You need to equalise the pressure. Too much back-pressure from the sprinkler will cause the siphon to fail.

[@edwardfernandez7516]

Hi Chillichump,thank you for your reply,how would one set up the system after Venturi device to avoid too much back pressure?a regular garden hose nozzle or gun would be a possible problem?i'm almost ready to order this device and my hoses are 5/8 with 3/4 standard conection to the house bib(Bib flow 9 gpm,wand or gun in hand now is about 6 gpm).should i buy a 1" Venturi,that's also where i'm confused.what's the brand of the one you have?

[@pippo8843]

hello nice video ... I bought the same thing but it doesn't work. I have a drip implant and it doesn't work. while if I leave it without the implant it goes. because ? thank you very much

[@ChilliChump]

If you restrict the flow of the output with things like a dripper, then this will not work. It requires decent flow

[@pippo8843]

@ChilliChump thanks for the answer ... i have a doubt .. the drip system does not generate pressure? the water does not return? maybe that's why it doesn't work?

[@LoFox]

I appreciate the content and really like your accent? Are you South African?

Ma usá na bottiglia trasparente?no? Dal tubo trasparente me sembra proprio che non passa niente sai com'è

[@franchosis]

Hey Chillichump, do you ever have problems with a venturi syphon not syphoning for some reason? Do you feel it mixes properly and efficiently? I am looking at adding this in line to my irrigation system right after the booster pump but also before the valve manifold so that I can fertigate my lawn & plant beds through the irrigation system. Would you think that this would be the best/ most efficient delivery system?

[@ChilliChump]

I think a Venturi system could work for you...but not this specific one. You would need a much bigger system, more flow. The problem you will have is the pressure...too much or too little pressure can cause this to be unreliable

[@leehawkins1533]

Cannot get this to work for me, The only way i can get it to suck is if i have an open end on my hose

[@ChilliChump]

You need to balance the pressure. If you have too much back-pressure coming from whatever you connect at the end (sprinkler etc.) then the siphon won't work. So play with the flow rate.

[@rayellery7596]

WHERE DO YOU GET THE TELLOW FITTINGS THAT SCREW ONTO THE INJECTOR SO JOIN THE HOSE PIPE

[@ChilliChump]

Ray, I have it linked in the description of this video...along with everything else: geni.us/hozelocktapconnect

[@pypypy4228]

Does it maintain the same ratio of fertiliser/water irrespectively to water flow rate?

[@ChilliChump]

In my testing yes....unless you are going to extremes (i.e. too high, too low)

[@RAMKUMAR-mb3hc]

Thanks. I have the siphon working. But when I attach the outlet to a sprinkler, water back flow through the siphon. How to prevent this

[@ChilliChump]

Hi Ram, when you say backflow....how do you mean? Is water going into your fertiliser resovoir?

[@RAMKUMAR-mb3hc]

Chillichump Thanks for reply. Yes you put it right. Siphon works the reverse way, water getting into the fertilizer reservoir. When I attach the outlet to a hose pipe, everything works fine - meaning siphon successfully suck the liquid fertilizer, mixes with water and deliver via the hose pipe in the outlet. But the moment I connect the hose end to a impact sprinkler, water back flows via siphon. Meaning water comes out via siphon. So the siphon works the reverse way. I guess when we attach a sprinkler, a pressure would be generated at the hose end which may cause the water to back flow and come out via siphon. I wonder how it works for you.

[@ChilliChump]

Might be a silly question, but are you sure you have it pointing the right direction?

[@RAMKUMAR-mb3hc]

Chillichump Yes 😀

[@ChilliChump]

Ah....ok I just read your second comment again. I think the pressure is too high on the sprinkler end, and the water has nowhere else to go except into the siphon part. Have you tried turning the tap down a bit so there is less pressure buildup at the sprinkler end? I just tried with my setup and if I have the tap on fully open then I get the same issue.

[@edwardfernandez7516]

Hi Chillichump,can I use a hose longer than 50' with this device?? (actually my hose is a 5/8 or 3/4 diameter and is 78' long, with a high flow garden hose gun at the end,)will it work? some kind of siphons systems are limited to 50' hose length from after the device to the nozzle or gun.

[@ChilliChump]

The length of the hose doesn't really matter...what does matter is how much back pressure there is after the Venturi device. It is a balancing act to get it right.

[@Tara-sf7uu]

Im not sure if the issue is that I also have a dial type timer on my hose, but my venturi has been a freakin nightmare! Instead of drawing out the fertilizer mix, it backflows into the fert bucket.

[@ChilliChump]

Hi Tara, may be a silly question...but are you sure you have the venturi going the right direction? There should be an arrow on the device to show the flow direction.

[@Tara-sf7uu]

@@ChilliChump yes, I thought the same thing and double checked the flow direction, and it was correct. It stumps me, lol. Im new to the injection systems so im not sure what else it could be

[@ChilliChump]

@@Tara-sf7uu try reduce the pressure from the tap and see if that makes a difference

Thank You

[@mouradbensalah9995]

thanks to yo i need a same video in frenshe langage please

[@adzza83]

I bought this exact syphon, and try as I might just cannot get it working properly. It sucks through fertilizer for about 3 seconds then just stops and doesn't pass anymore. Any ideas? If I disconnect the outlet side of the syphon while water is passing I get covered in seasol so I know it works but the second I reconnect the outlet it just slows and stops :(

[@ChilliChump]

Hi Adam, have you had a play with different pressure levels? When I first started experimenting with this I had to get the pressure just right. It is a bit of a Goldilocks situation.

[@adzza83]

Chillichump I’ll have a play. I assumed fully open would definitely work?

[@ChilliChump]

I found I needed to start off slow, then ramp it up. It helps if your fertiliser is dark coloured because you can see when it starts to pull through.

[@MrToupsClassroom]

@@ChilliChump I like Goldilocks

[@gordonjchambers]

Thanks for the post, I've been looking for something like this for ages. I'm a bit confused by the sizes quoted by various retailers on e-bay though. I have a standard 13mm hozelock hose with standard connectors which appear to me to have a 25mm or 1" thread. The retailers seem to be offering these with connecters with a diameter of either 20, 32 or 50mm - none of which would appear to be correct. Here's and example listing: bit.ly/2KcXhTX. Which size do I need or are none of these correct?

[@ChilliChump]

Hi Gordon. If you get the 20mm one, and also a pair of these hozelock connectors: amzn.to/2Iy989q then you should be set

[@gordonjchambers]

Thanks! Ordering now...

[@onyee8024]

what size venturi siphon did you use? and what is the size of your hose?

[@ChilliChump]

My hose is a standard 13mm hose, and the siphon is also a 13mm (0.5 inch).

[@onyee8024]

Thank you for your response. i was asking because i attempted the same set up - and was unable to get the siphon to actually siphon when hooked up to the sprinkler. When the hose at the end is just open with no sprinkler/nozzle then the venturi siphon will siphon upfrom my bucket. It seems that any restriction at the end of the hose prevents the siphoning effect. Ill mess around with it some more in case i messed something up.

[@ChilliChump]

There is nothing that you have messed up. I also had to play with the pressure a little bit from the tap end. If there is too much pressure pushing back from the sprinkler end, then it doesn't work well.
