Build your own hydroponics system with pvc pipes in 6 simple steps.

First step: installing PVC pipes

To hold the netcups, the system’s first step is to drill holes in the pvc pipes. A straightforward hole drill can be used for this. Since most netcups are conical, their upper diameter is larger than their lower diameter.

This is a necessary prerequisite so that the netcup can be submerged in the pvc pipe to a large extent without falling into it by drilling holes that hold the netcup in place. Of course, you need to find netcups that are the proper size for your pipe.

The netcup should hang in the pipe completely without having too much space between the cup’s bottom and the pipe. Remember that later, at least during the initial weeks of growth, you want your netcup to get wet from the water flow.

The water level can be lowered later. For our previous system, we used netcups totaling 68 mm (2.7 in) high for a 90 mm diameter pvc pipe (3.5 in) The distance between the cups is another crucial consideration.

In order for plants to grow properly, there needs to be space between them. Additionally, the kind of plant affects this. You might need more space between short, broad plants than you would if you were planting long plants.

Before you plan your holes, measure the space that will be left after the muffle is on. This is crucial if you are going to drill the holes and measure the distances because you need to close the pipe at its ends and the muffle requires space.

These measurements were taken using our previous system:

  • For a 90mm (3.5 in) diameter pvc pipe
  • We used netcups with a height of 65mm (2.7 in)
  • And put 7 cups on 1 meter (39 in) of pipe
  • we planned with plants not needing too much space, and would rather make less netcups per 1 meter than 7.

The lids or muffles for the PVC pipe are usually glued on and need to dry for about 24 hours before being applied. Of course you need to bring the pipe fitting lids. Make sure the glue is both water-resistant and hygienic for drinking water.

Even though drinking water won’t be your source of nutrients, you still intend to consume your harvest. Of course, the pvc pipes themselves are the same.

Drilling the inflow and outflow holes for the hoses is also necessary to complete the pvc pipes. The outflow hole is on the bottom of the pipe, and the inflow hole is where the holes for the netcups are.

Make sure the outflow hole precisely fits the used hose; otherwise, you must seal the connection between the pipe and hose in order to prevent the loss of nutrient solution. It is also very helpful if you are able to adjust the height at which the hose extends into the pipe.

This can be used later to change the water level in the pipe. As a safety measure to prevent flooding the pipe and the potential loss of nutrient solution, the first inflow from the pump to the first pvc pipe in our system is a smaller hose than all the pipe connecting hoses. Because you might want to adjust the precise height of the hoses within the pipe in the future, your hole should accommodate the correct size of the hoses you are using.

Pro Tip: If you can purchase white pipes, you should do so. If you are unable to do so, we advise painting your pipes white. The majority of pipes are black, which can accelerate heating up all the roots and potentially harm them. This keeps the interiors cool.

Step 2: Create the System’s Structure

You should begin with the overall framework of your system after you have finished with the pipes. In our illustration, we suggest creating a ladder-like rack that is simple to construct, can be leaned against a wall, and has both a vertical and horizontal spacing.

Build a Wooden Pipe Rack in Step 2.1

There are numerous possible builds. Use a structure that resembles a ladder, like the one that has been suggested, and lean it against a wall. Alternatively, you could construct a free-standing pyramid with pipes on either side to provide more room for growth. Every structure you can think of has the following characteristics:

1. The separation of the pipes

Because your plants need room to expand, you should leave some space between the horizontal and vertical pipes. You can build your system vertically, which already gives you a lot more space than a typical farming or gardening method.

However, the type of hydroponics system we are constructing here can also be easily spread both horizontally and vertically. In our illustration, we use mostly vertical spacing between the plants and a small amount of horizontal spacing thanks to the ladder shape.

Of course, the kind of plants you want to grow ultimately determines this. Do you want to grow salad that stays small or tomatoes that grow tall?

2. Construct the framework to withstand weight.

The system will contain pvc pipes that will house the plant, the roots, the growth medium, and water.

Depending on the plants, the growth medium, the length of the pipe, and other factors, it can all become quite heavy. This might be the heaviest if there is still water in the pipe. Therefore, design your structure to bear those loads.

Additionally, you want to scale later, so design a rack that accommodates scaling as well as the additional loads. You should first ask yourself how many pipes you want to start with as well as how many you want to add later.

3. The lowest point must be the reservoir.

It’s crucial that the reservoir is lower than the lowest pipe in your system in order to create a natural water outflow back into the reservoir.

Therefore, if you can’t dig in the reservoir in the ground, you can’t start your first pipe at ground level. Additionally, your structure needs to account for any future reservoir scaling plans.

Attach PVC Pipes to Rack in Step 2.2

You already have the pipes and the rack; all that is left to do is connect the pipes to the rack. Using pipe clamps, which you first attach to the rack and then the pipes to, is the simplest method.

There is only one thing to take into account when doing this: Since you want the water to flow down the entire system, attach the clamps so that the pipes are at an angle. Overall, the water should move down the system in a zick-zack fashion.

One factor determines the angle: Do you want a natural water flow only, or do you also want water to always be present in the pipes regardless of the flow?

If you want to combine the system with the idea of an ebb-flow system, you can raise the water level using the hoses, so you might not need that much angle at all. However, if you want your pump to run constantly, a flow is sufficient, so you should add more angle.

To maintain a constant water level inside the pipes, our advice is to have a slight angle and raise the hoses. In addition to preventing root burn damage on hot days, this also conserves energy because the pump doesn’t have to run constantly.

You can secure the pipes to the rack once you’ve decided on the system’s angle.

Setting Up The Reservoir in Step 3

after constructing the structure and the pipes. It’s time to discuss the reservoir itself at this point. One element that is essentially the same in many different hydroponics systems is the reservoir.

To stop algae growth, you need a container that blocks all light. It also needs to be big enough to hold enough water to keep the system running for a while. Finally, you need a submersible pump that can raise water to the height of the system’s entryway.

Your pump should have sufficient power to be able to pump a system up to a height of 2 meters.

We can now take care of all the system’s hoses after setting up the reservoir. To truly have flowing water and avoid standing water, create a zick-zack flow.

Water flow is crucial for your system because the splashes from water drops also introduce oxygen. As previously discussed, raise the hoses a little bit to maintain a constant water level in the pipes.

Now, as we already discussed in the preceding steps, it is strongly advised to use a thinner inflow hose when connecting the pump to the system itself than any of the out- or throughflow hoses. This acts as a natural overflow preventer. It might help in mitigating an overflow situation, but it does not guarantee one.

Fourth step: Plant the seedlings

The only thing left to do is add some plants to your system after it has been set up. The previous steps all need to be completed just once, but the subsequent steps may need to be repeated each season or whenever you add new plants to your system.

When to transplant seedlings is one of the most frequently asked questions, and there is really only one straightforward response: as soon as the seedling is transplanted, it needs to be able to access the nutrient solution in its new environment. It all comes down to the root length developed during the seedling phase, depending on how your system operates.

When should seedlings be transplanted?

As soon as the seedling’s root is long enough to pass through the growth medium and the netcup and reach the water, you can transplant it.

To transplant your seedlings, you will also need a growth medium and clay pebbles in addition to the seedling itself. You can use and experiment with a wide range of growth media, of course.

We had success with sponge because you can purchase them with a cut inside that makes it easier to wrap the medium around the roots of seedlings when they are being transplanted.

Additionally, you should avoid placing your plant too low in the netcup. If you run out of medium, you can fill the netcup with pebbles, which also absorb and store nutrient solution. You are prepared to insert the seedling into the pipes after combining the medium, clay pebbles, and netcup.

After relocating your seedlings, you can put the entire system together. As a result, you now have the structure, the pipes, the reservoir, as well as the seedlings.

Prepare the nutrient solution and the timer in step 5

It’s time to tend to your plants’ food needs right now. The two crucial metrics for a hydroponics system are pH and TDS, as we learned in a previous post.

Use the Hydroplanner, which assists you in deriving those values for your plants, to learn what values are appropriate for the plants in your system. If your system has been designed appropriately, you are aware of the values you should pursue.

Therefore, those values must now be reflected in your reservoir and contained nutrient solution. To achieve this, first use a pH meter to measure the pH of your solution and then adjust it using pH Down or pH Up to the desired level. Hydroponic fertilizer should then be used to set the appropriate TDS value.

Once your nutrient solution is complete, check the pH and TDS levels frequently. The growth of your plants depends on those values being in line with their preferences.

You now need to control the proper flow of the nutrient solution in your system in addition to managing the nutrient solution itself. The simplest method for accomplishing this is a timer that turns the pump on and off.

To avoid overflow, we advise brief intervals with brief pumping times. Larger roots from the plants will likely clog your hoses as they grow. Since it’s difficult to stop this, the water may still be able to pass through your system completely if you pump frequently for a short period of time.

Specifically stated, pumping for two minutes every twenty minutes might be a good place to start if you want to give your plants enough nutrients and avoid overflow and water loss. This also depends on how big your system is.

Let the hydroponic system run in step 6

Your system is now ready for use, and you can start growing a variety of different plants, vegetables, herbs, and fruits. Let the system operate while you conduct experiments using various plants, grow mediums, structures, pipes, and other factors. Start developing and learning. To increase yield and plant happiness, make regular checks of your vital signs.
