How to Make the Best Raised Bed Irrigation System Even Better


[music]
Alright! This is John Kohler with growingyourgreens.com, today we have another exciting episode for
you, and for those of you that have paid attention to my YouTube channel and have been subscribers
for a while, you guys know that I actually installed the Aquajet system and we can see
I’ve kind of partially dug up part of this set up for the last summer growing season.
Had some amazing growing results, its done very well, and I recommended it to many people
actually, because if you get the kinks worked out, it works great, you know. That being
said, there are some bugs, and be sure to check my past videos that talk about this,
so I’ll put the links down below if you want to see the Aquajet saga. And this is
the latest update. So now it’s past the summer season, pulled up my pepper plants
out of this bed a while back, for those of you guys that remember, this is the bed that
was the experimental bed, I tried to do a single Aquajet system right down the middle
of the bed to see if it would spray out two feet or more specifically in this specific
bed, 22 inches each way, and based on the testing it actually was not able to perform.
It didn’t spray out 22 inches, probably sprayed out a good 12 or so inches, maybe
12 to 14 inches I’m guessing, because my plants on the very ends, some of them made
it, but some of them did not. So this is not a good thing, I was not happy, so what happened
was I kind of knew this was experiment and I’d actually plumbed in some piping to basically
come up here and here to basically make a racetrack design, which I’m glad I did that,
I always like to plan ahead because digging all this up would have been a pain in the
arse. And so then we got this put in, and you know it actually worked fairly well, the
only challenge I had is because of the depth of the pipe, it would actually make these
holes that I would have to continually fill, which was another pain the arse. So now that
the growing season’s done my plants are out, I’ve dug this up so I can actually
pull out the center pipe because I couldn’t do that during the growing season because
I’d disturb too many roots, and we’re basically going to cap this center one off
and just leave the two outside ones to form the racetrack, but I wanted to show you guys
and basically let you guys know as I have recommended the Aquajet to many of you guys
up to this point and it does work, I did get better than ever growing results ever, and
I do want to admit that I am an early adopter, there is a reason why I can’t recommend
it anymore, and we’ll go over to the other bed to share with you guys that in a second,
but the first thing is I wanted to show you guys this, so the depth. I mean this is probably
one of the most critical things, one component of one of the most critical things when installing
the Aquajet is to get the depth correct, right? On a drip irrigation you lay it above your
soil, the water flows down, and on the Aquajet, the high pressure goes out and the water [inaudible]
up, now we have a thing on Earth called gravity, and while water does [inaudible] up, if you
spill water and you use a towel to soak it up, the water literally [inaudible] up into
that paper towel like up, like oil wicks up through wicks to get burned and all this,
that’s kind of like a [inaudible]. And the water comes out and some of the water falls
because gravity, but then some of it will [inaudible] up, and this depends on your soil.
Now specifically I’m talking about a raised bed with looser soil, not a compacted turf
application. In turf applications it’s different, you know, they bury the Aquajet at six inches,
so in my bed here, when this was originally installed, this main unit was installed and
I put a board across the top so I can see where the top is, it’s basically dug into
a depth of five inches deep. Now this I feel was a little bit too deep, then they came
in and they installed this one, and this one was the racetrack design, and this now is
actually at just about three inches, maybe two and five fifteenths sixteenths, but just
about three inches. And this in my opinion is too high, because now I get to see the
piping even if I fill my raised beds to the top you see some piping, which I don’t like
to see that. And also it makes these holes that I’ve got to continually fill that haven’t
gone away. So I think the optimal height would be right in the middle, you know like Goldilocks
and the three bears, porridge was too hot, too cold and “oh just right.” So I think
if you dig a trench like four inches deep, and then you lay the Aquajet in the bottom
of the four inch trench, because this was five, this was three, it would be about right
here, I think that would be just right. And if you do that I think the Aquajet’s going
to work amazing, except for the next thing that I’m going to show you, and the big
reason why I can’t actually recommend it to any of you guys out there right now at
this point in time for raised bed garden installations. Alright so as you guys can see this is one
of my long beds, this is the bed that we originally put a racetrack design in, and as you guys
can see, I’ve kind of just dug out the soil above it so you can kind of see it like sunk
in into the dirt there, and this probably comes down to the reason why I can’t recommend
the Aquajet at this time, although this is subject to change if they get it corrected.
I mean I want to admit that I was an early adopter, just like if you buy a computer and
it’s got Windows XP maybe I’m dating myself there, has a lot of bugs and crashes a lot
but they came out with what, Windows Vista, Windows 7, Windows 8, are they up to Windows
9 yet, does it still crash? But I was an early adopter and so problems will come up, and
I think the beauty of a company is if problems do come up, they fix it. I mean I got this
little health meter watch thing right, and it had big issues with it, software wasn’t
working and all this stuff, and the company apologized, gave everybody an extra free year
on their subscription, and they’re fixing the issues and taking care of it. I mean this
is super-critical, because nowadays it’s all about customer service, and this wouldn’t
have came up if this didn’t happen to me, because I am going to be planting out some
of my winter crops here, and I’m not going to plant my crops in a bed where it’s not
going to perform and they’re not going to get proper water, right? Because now it would
basically be sentencing them to not living, which would not be good, then I wouldn’t
be eating, and then I wouldn’t be living. So I want to eat, and so I thought “Oh man,
I had that big problem with the Aquajet in my long bed, I made a video sharing why this
happened, the system was installed too deeply and it sunk down.” And in this bed, pretty
much the same thing happened. Number one, the system was installed improperly, and number
two, it sunk down over time. So what we’re going to do is we’re going to go ahead and
measure how much it sunk down, I don’t remember exactly how deep this was originally put in
at, I probably should have measured each one, but basically we’re going to go ahead and
dig this out a little bit to see the depth we’re at, alright I think my hand is underneath
there. And so we take our ruler here, go down, this was probably, at this point it’s sitting
at about five and a half inches deep, so this is one and a half inches too deep in my opinion,
especially for the lettuces and some of the other tender winter crops that maybe the root
doesn’t penetrate down as deep as say, tomatoes or peppers is what I grew in here over the
summer. And I did have to water in the peppers to get them established, but once the roots
went down, they found the water and everything did beautifully. Now the other thing you might
be thinking “John, how deep was it buried down at the other end?” So actually lets
go down there and share with you guys how deep it was installed at, installation depth,
because the pipe was installed at a certain level, it can actually flex up or flex down,
and at different points in the bed it may have wave, so it may be deeper or more shallow
at different points in the bed, so let’s go down and see the original adjustment where
it was cut and installed at. Alright so now we’re at the side of the
bed where basically the pipes come up and then the Aquajet ties into it, now we’re
going to check the depth on this one, and we’re going to go ahead and take this guy,
put it right over the top so we kind of know the top of the bed. I mean this is probably
the most critical measurement when installing the Aquajet is have it at the right depth.
And so it looks like the pipe in this one is approximately six and a half inches deep,
so this is two and a half inches deep, in my opinion it should be about a four inch
trench, this is six and a half inch trench, quite deep, once again over to this side,
once again actually it’s right at six and a half inches. So this is definitely too deep,
I’m going to have to go in there, clip it, raise it up, and do all this kind of stuff,
but then the problem still arises that even if I get it at the right depth, right, because
my soil basically compacts and is some compost, it breaks down over time and it will sink,
actually. And due to this, this will continually drop down and drop down, and become lower
and lower over time like this end is always going to stay stable, but the other end is
going to end up flopping down over time. So what needs to happen in my opinion so that
I can recommend this again and be a happy Aquajet customer because I want success for
me and not having to dig up my bed every time to tweak in and raise it up and all this kind
of stuff, I want the Aquajet company to come out with a standoff, basically a piece to
hold the Aquajet and to mount it on a piece of rebar tubing so that it remains stable.
So the easiest thing to do for a situation like this is you’re going to get a piece
of rebar, this is just a stake here, and you can just have that set down, and then what
you’re going to do is you’re going to just take the Aquajet here, and basically
a standoff could just have a little U that goes on top of the rebar that basically just
holds it in place and holds it steady, or you could have a side mount that actually
clips on and then basically caps over the top to hold it like this. I mean these are
just two easy ways that this solution can be fixed, I mean the watering in the Aquajet
is amazing, it aerates the soil which is amazing, but it sinks down over time and gives me headaches
right? Like during planting and having to dig things up, I don’t know about you guys,
but one of the things as I get more wise in my older years is that I just don’t want
headaches in life, I want everything easy I don’t want to dig things up every season,
I don’t want to think about it, I just want it to work properly, and yes I’ll give you
that, my drip irrigation system it does give me some headaches also, and I do believe that
if the Aquajet company came out with this standoff piece, this system would be damn
near perfect and be able to save you water, allow you to have better plant growth, and
just work amazingly overall. And so I do hope that I have a future episode with the owner
of the Aquajet company helping me out installing the standoffs in my beds so that this is no
longer an issue, and all my plants can continue to thrive, but more importantly all you guys
out there watching, your plants can continue to thrive as well with the Aquajet system.
So that’s why I can’t recommend it at this time, although it does work properly
there can be long-term issues with it sinking down, not being at the right level, and then
your plants not getting watered and losing your plants’ lives, and that’s no fun,
I’ve lost at least four dozen plants when I originally installed it when it was a the
wrong height, and even after trying to replant when it was at the wrong height after raising
it up because it continued to sink down, lost a few more plants and things did not grow
optimally. So yeah I hope this situation gets resolved by the manufacturer real soon, hope
I’m able to have an update video and when I am I’ll put a link down below this video
so you guys can see the update and know that once again I will be able to recommend the
Aquajet system to all you guys out there. Hope you guys enjoyed this episode, I’ve
got to get back to fixing this stuff and planting out my lettuce, once again my name is John
Kohler with growingyourgreens.com, we’ll see you next time and until then remember,
keep on growing. [music]

    Thanks John!  Good and honest evaluation.  I personally did not like having pvc pipe material in my soil being too afraid to hit it while planting and moving in new compost etc.  I have been using automatic soak-er hoses left on the surface. Doing compost tea this year.  Amazing results already!  Thanks for the Joshua videos!

    I think maybe when doing the racetrack design you could just put 1 feed pipe at each end. Basically have a T shape instead of a U shape. that way the horizontal part would hold the Aquajet at the proper height on each end. As for the center I would just dig it out and put in a brick or two to keep them at proper height. 
    Expecting the company to build a support is probably a little much considering every single raised bed is going to be completely different. My beds just went in this year and Im doing all drippers. We will see how it works this season.

    I've also used the system for many years. Both for annuals in raised beds and with fruit trees and cane fruit in long stretches. Besides the issues you mentioned, I've also consistently had problems with the spray holes plugging up. Monitoring for dry spots and then digging down to unplug them is a real pain. It seems to be bacterial and algae buildup. I've not removed the system, but have been switching back to drip for raised beds and drip stakes as I detect issues with the non-annuals to avoid disturbing the roots. I love the concept, but the execution is not there yet.

    Yes i gave up on earthmister after wasting $500. Never worked as stated. Too many variables that are difficult to adjusr, imagine if you don't have a custom soil mix like John. The wickability of the soil to draw up (or down) moisture will be critical in determining the height of the irrigation. Imagine trying to plant seeds and ensure appropriate moisture when placed at the recommended 6 in depth (it was then).

    After trying all different types, including the earthmister, what is the best solution I have found? The Mittleider Irrigation method, it's inexpensive and you have total control over how much irrigation is done.

    Soil compaction as you said is the inescapable failure point for this system. The surface distance from the piping will always be in flux requiring constant upkeep by the gardener. As great as the jet idea is, it will likely never be practical.

    Upon your past videos, I had made a large purchase with AquaJet. I followed your past concerns with the level of the AquaJet up and down in your long single run. The owner I thought had assisted you with it's correction? I will be installing the AquaJet this Fall and thank you for your concerns of maintaining 4 inches for raised beds. I am sure AquaJet will have a solution as this is definitely the best water system out there as your crop as shown; especially your peppers. I understand that the top level of the soil will sink/compact throughout the year whereupon the gardener should only have to add more to maintain the 4 inches. Looking forward to the next video on this topic.

    I have the AQUAJET installed in two of my raised beds for over a year now.  I have not had any of the issues you are experiencing. I have had nothing but success.  I will continue to use and recommend the AQUAJET.  This product is kickass!!

    I would like to see more tests on minimum water usage.  You live in a drought.  How can people grow their food without using a lot of water?  Drip is a start definitely, but I think mulch is needed to retain moisture.  How often is it necessary to water and get healthy plants?   Grey water use?  Minimum land usage?  As far as I can tell, raised beds cause higher evaporation rates and warmer soil temperatures.  I currently use about 3 gallons of water a day and I live in Wisconsin where there is plenty of water, but as a population, what we are doing is completely unsustainable.

    Well it was a good idea but it makes sense that it sank because of the pressure of the water.  With nothing to hold the soil together the water pressure would percolate the soil while watering. Quite honestly that is too much pressure for loose soil you are going to have problems of erosion every time you turn it on

    Put a few boards in run from ledge to ledge.  Use wire attached to the board to the pipe of fixed length.  More boards across the more stable…with minimal loss of space.

    Thanks for the very timely update, John. I was just starting to consider the Aquajet system for my own raised beds, based upon your earlier video. I see the issue you've raised and think your proposed solution would prove an easy fix. Not wanting to wait too long for a factory solution, I think using a length of rebar with a "U" shaped piece of rod welded to it to hold the pipe secured with a tie wire will suffice for me. Just my thoughts. Thanks for sharing.

    Mulch like crazy and watch your worm population go up, while massively reducing water consumption. Technology is cool, but sometimes things are best kept simply for a reason. With that being said, if you BALLIN' then by all means, throw some money at it and see what happens. I like the exercise of watering my plants…I figure by eating healthy and exercising (a little) while maintaining my food, I'm not going to have to waste TONS of time (and less importantly, money) in the Cancer unit or Cardiac unit, etc. HEALTH is WEALTH peeps!!!!

    Yeah, I'm moving away from in-ground irrigation totally – I like the concept (water saving etc) but the maintenance of these systems is just too much. Even risers or drip irrigation can be problematic with clogging or poor coverage so it's about finding a way that suits the grower/gardener that is effective but not time consuming or overly expensive. It also depends on how big your vegetable garden is and the type of beds. I'm strongly considering going back to automated overhead watering (even with some obvious negatives) I think the pros outweigh the cons for a large food garden.

    your stand off idea will work. How about thinking of laying a horizontal bar attached through holes drilled in your cement blocks at the desired height to hold the lines up. That seems to me a good way to build a grid that would support the watering system. the holes could weep out some soil but some thing could be used to plug that. If maintain depth in a raise bed is the only downfall it may be worth a try. or just attach it with a cable tie to your stand off those things are like duct tape in the many uses and you can get one that release for multiple uses or adjustments. You can get to work'

    Jon, Thank you for thoughts… but did you ever call Rob to see he would repair/fix this problem??
    Now in your defense, when I watched the install videos of your system, I was thinking at that time, that saddle supports were need every 3-4 feet to keep the pipe level when that awesome dirt of yours de-composes.
    I have had some communication with Rob about his product and he is a nice guy.
    And he did admit he one of his videos, that his helper did the install.
    I also watched one of his videos and realized that his is not a plumber, I commented with a suggestion and he said that he would take my advise…… He invented a good product, but installing it are two different things.
    Answer me this.   How good were you twenty years ago with gardening ??

    Dude are you seriously bashing the aquajet over a couple of dead plants, by what I could see by looking at some of your past videos you had a straight jungle back there.  I am a custom steel fabricator and if things are not going the way I visioned I fix it simple as that, but to cry to all your viewers that you no longer recommend this product because of a elevation problem in my opinion is wrong. I personally am running two aquajet systems and not one complaint yet.

    PVC systems are antiquated and problematic and difficult to make changes to. PVC also degrades quickly and leaches chemicals into the water and soil…

    Most sub irrigation planters for larger plants, such as raised beds built with pond liner and drain tubes, dutch buckets or rain gutter grow systems, wicks water from around a foot deep. Some less and some even more.

    I use kind of a rain gutter system myself, and my water level is a foot below soil level and easily wicks all the way up. So only six inches really shouldn't be a problem for you, unless your soil have vary bad wicking properties.

    Perhaps you could try adding coir or peat moss to your soil in order to make it wick better?

    So …. irrespective of this irrigation system, was your soil too heavy and compacted, versus a loose soil, or that your irrigation water pressure was too low, … that eveyrthing wasnt up to snuff for what the irrigation system could not perform to its highest potential.

    is your system less than ideal, versus that of the aqua jet ?

    I have been watching John for awhile now. Love the vids, a lot of great info. Unfortunately when gardening gets to this point it gets a bit crazy. My grandparents gardened without all of this technology and did fine. Now today it's not good enough to have a 3 ft tall broccoli plant we have to find a way to grow a 15 ft plant. Johns garden is already awesome, how much more would a person need? All of this technology takes the fun out of gardening. The organic nature of gardening is lost on all of these gadgets. Drip irrigation works well enough and I live in Phoenix. I grow all kinds of vegetables and do well even with the heat. Keep it simple, immitate nature as much as possible and enjoy yourself.

    I feel in love with the concept of this system. I brought right in to it when they were called Earth Mister. Man talk about problems, I kept getting all the wrong parts. shorted parts. It was the biggest pain to work with these guys. They didnt service after they sold. They sold me fittings that leaked, I had been shipped two different types and all the black ones leaked. Once I finally got it installed it did not work anything like they promised me and I had to go upgrade my pump because they told me it would work for a long run but never tested it themselves. I think they changed their name just to avoid all the people like me who got screwed. Not only do these pipes move, they started to crack after the second year. I am in south FL and it has NEVER frozen here. I also used the tree spikes only to find my fruit trees are doing really bad. Well they have NO roots! Roots are only around the spikes and you need 3x what they tell you to use. I put 3 tree spikes on each tree and not enough water was being delivered. When I pulled up a dead tree only to see NO deep roots and only small roots around the spikes. The water never sprayed far enough or delivered enough water. The owen just hid from me. I wish I could send all this junk right back to him. After my mulch biodegraded I found HUGE pot holes everywhere this pipe was run. ITS A JUNK system. I recently found out, this is an OLD concept that this company picked up after a patent expired. I found reports of field test where Orange trees blew over because they didn't have the correct root system due to this type of watering. I think his name is Rob, I told him this system could only work if you wrapped a box around your plants, Then when he changed his name to Aqua Jet … what do you know he started selling kits for raised beds to box it right in. Uummm,, well at least he does listen to his customers some what. LoL I have to run the system so much it never really did save any water. I still had to push 100 gallons a week to my bananas. Then it got worse because the water didn't make it anywhere I had to UP the watering to keep up with the plants. Drip and Micro sprinkler are the best still.

    Holding PVC up with stands as the ground settles creates tension points, that can break pipe, this system would work best in an established bed with minimum settling. Pipe company's can not really fix this issue. it is a problem with all underground utilities. It is the same reason they rock and compact under sewer pipe to prevent this exact issue.

    Being a Pipe Layer myself, I would think with a newly filled bed your going to be dealing with this problem for years to come. Stands will work but not without a risk.

    My question is do you turn the soil in your raised bed and if you do, what is the trick with the pipes buried underground?  I have raised bed and I do it the old fashion way, with a pitch fork.  I tried a tiller but it's way too big for the beds.  I am now wondering how on earth am I gonna do it when I'm 70 yrs old other than hire the local kids.

    There's no way I'd install something like this in the first place. You recommend rubber hoses to avoid heavy metals and other problems with regular garden hose, and then you bury PVC in your soil next to the plants' roots. It doesn't last, for one thing, and it seems inconsistent with the former recommendation.

    Mulch and drip. Hugel beds. More mulch. And more mulch.

    I love your garden, and your enthusiasm. I don't even mind the product pushing much. However, I'm not sure why I spent $100 on the rock powders when I'm sitting on a dolomite shelf here in north central Texas. And I've never had much need for raised beds here on the farm.

    Thanks for the update John, we just started working on trenching for an irrigation system last weekend. I've been following the Aqua Jet saga and despite the trials am still interested in giving this a shot in at least one of our raised beds this year – the way things are going out here in California we'll be facing similar conditions to yours pretty soon (!) – and some sort of sub-soil watering solution seems like the most responsible thing to do. Based upon what you've shown us I'm thinking about how I would support the tubing now which is better than thinking about it after all the dirt's in and the plants are planted. Thanks again for all your efforts, experimentation and great tips! -Matt

    It seems to me that every plant in your garden is from transplants – is it possible to direct seed in your bed using the AquaJet or how would you plant and grow a crop like carrots – without the water jets destroying the growing roots

    Don't know if this was thought of… didn't read extensively through the comments… how about, every 4-5 feet, cut the PVC and put in a tee. Then run a vertical piece of PVC down to the bottom and put an end cap on it?  Cheaper than rebar and would make for an easy fix. Just my opinion.

    Do you think if I space the piping closer together, keep it at 4", that I could run it off of a tensiometer (Irrometer MLT with electronic gauge interface)? Or should I be watering it on a set schedule like twice a day?

    any system of watering that requires it to be at an exact depth to work is not working, and should never be used. Also shooting water through the soil at high pressure to make under ground tunnels, which will fall in, disturbing the surface condition, only to be bored out again (hopefully) next time it turns back on is also a big X.  

    Any system that works on the premise of needing high pressure at 100's of locations is doomed. The amount of pressure needed at the head of such a system is going to way higher then any home has.

    Any under ground watering system will need to have a sock on it to prevent soil from clogging the holes. This in turn rules out this high pressure system. Talk to anyone that has ever had to dig up around there basement to replace the weeping tiles because they had the old weeping tiles that did not have socks on them because its clogged up now.

    The company put out some rebarb standoffs , would you recommend this over all products NOW…..??
     We will be buying land and setting up permaculture as well as raised beds again…but in Tx we really do need a solution. One thing high pressured water would cause tunneling…does this do that?

    If you no longer recommend this system why on earth do you still have the 40-minute video still up to view. I'm SO GLAD I didn't waste my time watching that whole thing before finding this update.

    John, why not place bricks stacked to the correct height with say a flag stone for foot pressure at the bottom of the bed for your stand-offs.

    Also, this water system can really work for a variety of plants if it was deeper by a couple of inches and the pressure hole were angled upward.

    Make it work! It will be be great!

    DO NOT use PVC for your garden folks!!!!!! Especially if you're growing organic. PVC is not food grade and is loaded with toxic chemicals (phthalates) that leach into the soil and get absorbed throughout your plants. Use HDPE / Polyethylene / NSF PW instead. A common brand is PolyFlex.
