  • The first thing I want to do is plot my holes for the net pots onto the system.

  • This system in particular is going to have six holes so I am going to go ahead

  • and cut those out right now with my 3 inch hole saw.

  • All right, so we now have all of our holes cut. All right, so the next thing I am going

  • to do is I want to lay out my pattern that I am going to be using.

  • So I will just grab all my fittings.

  • I got some t-joints and some 90° and I just want to layout where I want to have

  • everything sort of set. So the 90° are going to be on the edges,

  • all right.

  • The two joints --

  • All right, so what I have laid out here is sort of my pattern.

  • Now the 90° is going to create sort of the rectangle around the edge with like

  • the t-joints in the middle are going to connect up to create a center piece

  • and then this middle t-joint is actually going to point downwards and that is going to

  • connect to the reservoir pup in the bottom

  • and then I am going to use these two joints on the either side to create the lays.

  • So the next thing I want to do is cut the pipe for length so for this I am going to

  • use this pipe cutting tool that you can pick up at any home depot or whatever.

  • It cost about 10 bucks and I am going to use the length of the pipe so what I want

  • to do is measure out the length of the pipe that I am going to need for each of

  • the fittings.

  • Okay, so I am just about finished cutting up all my pieces, but what I want to do

  • before I move along is I want to dry fit everything and make sure it fits.

  • So all you have to do is just place all the pieces together.

  • I am going to go ahead and markup our final piece.

  • Get ready to mark your final piece.

  • What you want to make sure you do when you are doing your marking is you want to have

  • about a half a centimeter inside to about half a centimeter on the inside here as

  • well so let's go ahead and mark that there.

  • Right, so I am going to show you how the clamp works, but just basically pull the

  • clamp apart to reveal the blade and then find your mark and then you want to place

  • the blade right on to the mark by just compressing it and once it has got a grip

  • then all you got to do is just how to use it like scissors, right.

  • So you can get this last piece in.

  • That is going to take a little bit of wiggle always on the last pieces which

  • is a little harder.

  • So you get to see. We have our last bit of thing.

  • Now you can see one of the things that I have done is that I have made it slightly

  • smaller than the actual lid of the container. The reason for this is most buckets

  • actually get smaller on the inside so you want to make sure that it is going to go

  • in and out easily, yet that it is still going to provide coverage to all of your

  • net pots.

  • Now what I bought is these micro-spray heads. They give the 360° spray and what we are

  • going to do right now is mark out along the pipe where we want to drill the holes

  • for the spray heads.

  • So if we look at where our holes are for the net pots, we want to make sure that we

  • have equal coverage kind of everywhere so having one that right on top of the net

  • pot might not necessarily be good because as the roots grow down, they are going to

  • grow down and cover these so you want to make sure that they are sort offset, all right.

  • The other thing that you can do as well

  • is you can have different angles to have different coverage.

  • So what I am going to do in this case is I am going to put my marks with a Sharpie

  • wherever we think we want to have a spray that.

  • So I want one that coverage in between these two holes so I put a mark there.

  • I want to have coverage in between these two holes so put a mark there.

  • Here we are going to have coverage in between these two holes.

  • Then, we are also going to have coverage in between these two holes on this side

  • and between these two holes in this side.

  • We are going to make sure we have coverage here, okay and going along here

  • we are going to have coverage here,

  • coverage here and then we want to make sure that we do have some coverage on the

  • edges so we are going to put one here, here, here and there.

  • And that should give us a fairly even coverage, what we are looking to do

  • is just blanket for plants completely.

  • You could add a few extras if you want but like I said basically what we are

  • looking to do is make sure that they are not directly underneath the root system

  • otherwise the roots are just going to clog up and make these unusable anyways.

  • So you want to try to keep them away from the root system, but still with very good coverage.

  • In fact, I do think that we even have better coverage if I did add an additional

  • one here and additional one here as well

  • and this would provide a 360 to sort of all 4 pots.

  • So we are going to get a lot of coverage with this so let's go ahead and drill out

  • these wholes.

  • All right, now I know that the threading on these micro hoses are 532's so I am

  • gong to use my drill bit that matches that and what I am going to do is drill out

  • each one of these holes, but I want to be a little bit slow at it and make sure I

  • only go through the first layer.

  • I leave the system put together just to kind of provide me some support and you

  • want to make sure that you get somewhat bit on you don't want to be too cockeyed right.

  • So you just go through

  • and that is the last hole.

  • The next thing I want to do is I have a tap.

  • This is going to put the threading on that is the same thread as what is on this

  • bit here, okay.

  • So and that is going to create a 10/32 tap hole, and what I like to do for this

  • is I like to turn my drill to its lowest setting.

  • You can see how it is quite a bit slower

  • and we are going to be gently tap the whole and then reverse out and now you can

  • see we have a nice thread.

  • Just like that so I will go ahead and finish the rest of them.

  • All right so now that I have all my holes tapped what I want to do is address the legs.

  • So what we want to make sure is that when this sits inside the bucket that the spray

  • heads are going to evenly spray just slightly below the bottoms of each of the

  • net pots.

  • So in order to do this I will just take a net pot and kind of place it just slightly

  • below the edge of our container.

  • This matches the top of the bucket

  • and then I am going to measure up from the bottom and I can see from this that the

  • net pot bottom here is just at 9 inches from the top.

  • So I want to keep this again slightly below that 9 inch mark.

  • To accomplish that I also want to take into account how much pipe will be back

  • into this position.

  • So that is about a centimeter and a half-ish, right so if we had that for a 9

  • inch mark so it is about 8-1/2 inches.

  • So basically if I place 8-1/2 inches inside the bucket we are going to end up

  • just at that, just slightly below that 9 inch mark.

  • So now what we want to do is cut some 8-1/2 inch long pieces.

  • So what I will do is I will measure out 8-1/2 inches, place my mark and start cutting.

  • We are going to need four for this.

  • And we got our four legs.

  • All right so we got our four legs and what I want to do at this point is try to fit

  • those legs. So I will fit flip the unit over and we

  • are just going to turn each of our t-joints and we go ahead and place our

  • legs just like that.

  • Now the one thing you want to keep in mind is this entire system is going to have

  • water pressure running throughout. So unless we cap off the legs, then we

  • will actually have water shooting out of it and just become like a rocket take of

  • so just get your simple end caps and we will go ahead and cap off the legs.

  • All right, now that the legs are all capped off we can take the unit and fit it

  • in to our pail to make sure everything fits good.

  • You can see how we got a nice strong sturdy support so we can go ahead and get

  • ready to actually start cementing these. Basically, what you want to do is just

  • coat the edge with the solvent and then twist it into your fitting and then any

  • grips you can just clean up.

  • I usually suggest that you start with your easiest fittings first and then just move

  • on to the hardest fittings next.

  • So the thing I want to do now is fit this intake valve onto the bottom there.

  • You could do that much in the same way.

  • Just get a little of our cement and place it on like so and just press until firm.

  • And now we will be able to attach the hose to the bottom here.

  • At this point, you want to just let everything dry up.

  • It doesn't take long to set but I usually like to give it a good 24 hours to dry.

  • And now you can see that we have all the spray that is put into place, so all we

  • have to do right now is just go ahead and let this dry and then we can work on the

  • rest of it probably tomorrow.

  • One thing that you can do in the meantime though is you will notice that I have

  • started right now to sort of color this in with sharpie and black.

  • I think it is a really good idea just how to keep the light out.

  • If you have the ability to go outside and just spray paint the lid black I would

  • definitely suggest it, but if you get a big enough Sharpie you can see that it

  • is not going to take you all that long to get this painted black on the lid so for me I

  • am just going to go ahead and use a Sharpie to get the top black and you can

  • go ahead and do whatever you want.

  • All right we are back on day two and everything is nicely dry as you can see I

  • have all my emitters plugged in and now we are ready to deal with the actual feed

  • system for the pump.

  • So in order to do that much like my last project I did we are going to want to make

  • it notch in the bucket for our cable

  • and now we can have the cable just right inside blush with the top of the bucket.

  • So that takes care of our cable.

  • So I bought one of these half inch adapters and they just screw it right into

  • the top just like so and then I also have this half inch flexible tubing so what

  • happens is you just press fit right on to the system there and then we will just go

  • ahead and cut it to the length that we need to press fit it on to that side there

  • so put it in the system and go ahead and mark it right here.

  • Get a cutting tool and as you can see we just press fit it and to the system like so.

  • So now we have a good seal for the pump.

  • All right, so let's place it into our system and that looks about good there

  • and basically what we want to do now is find our water levels so this will be the

  • amount of nutrient that we need and the idea here is we don't need the nutrient to

  • come up very far, what we do have to be aware of is if you look at the side of the

  • pump here you can see that there is an intake and this is where the water

  • is going to come in through and go up to the top of the pump.

  • We want to make sure that the water doesn't drop below this level otherwise

  • you have potential of burning out your motor on the pump.

  • So when we set our water levels for the bucket we are going to want to make sure

  • that we haven't probably to about this level here, so just twice the amount of

  • water that is needed to cover this. That way when the spray had spray up we

  • will be able to drop the levels to a certain point.

  • All right so as you can see I have my fill line here.

  • This is a 25 meters.

  • If I was using this as deep water culture I would have to fill it up to 44 liters to

  • be able to get the same results so ultimately quite a bit of savings there.

  • So now that we have our system pretty much ready to go one thing I do want to

  • know is the fact that we do have a contained system meaning that reservoir

  • and the spray emitters are all in the same bucket.

  • That means that as the roots get longer and start growing down the task of

  • spraying theirs, they are going to start sitting in this water and it is going to

  • act like a deep water culture system.

  • So in order to prevent the roots from getting rots in that area, we are going to

  • still go with the same technique that we used in my previous model of the deepwater

  • culture and that is using one of these air stones inside there to make sure that we

  • keep enough oxygen.

  • So I am just going to be using one of these 12 inch air stones and that will go

  • right down inside of the system and what I have done is just simply drill the whole

  • at the top so that we can feed the air tube inside, all right and basically the

  • other thing I have done is made sure that all my cables are sort of in the same

  • corner so if I want to push that off to the side then I know that everything

  • is kind of coming out of the same spot.

  • But that being said let's go ahead and see this baby work.

  • Now for the moment of truth...

  • you got it spray everywhere without the lid on as you can see we have a working system.

The first thing I want to do is plot my holes for the net pots onto the system.
