Growing with hydroponics doesn’t have to be expensive nor do you need a huge grow room to take advantage of some of the automation and advantages to build your own marijuana hydroponic system. The DIY hydro systems below range from beginner to advance, hopefully, you find one that will work for you.
Here is a selection of the best homemade hydroponics plans anybody can build. These plans include beginner, intermediate, and advanced setups.
PVC NFT Hydroponics System
Large 4 inch PVC pipes can be used to create your homemade hydroponics system. In this plan, the plants are placed in cups which are arranged in holders drilled into the pipes.
The system is watered using a reservoir and pump. This is a closed system, with the water circulating between the pipes and the reservoir.
This plan is ideal for growing a lot of small plants within a small area. The basic system can house anywhere from 20-40 plants.
This system can be placed indoors or outdoors. If indoors, grow lights are of course essential.
The hydroponics method used in this plant is called NFT. It is an excellent plan for growing plants like tomatoes.
DIY Aeroponics Grow Box
This DIY plan is a very flexible system that can be moved around quite a lot. It can be made with any sized storage tub or bin. It should have a lid.
The system uses PVC pipes, a submersible pump, and irrigation sprinkler heads to deliver nutrients and water to the plants.
The plants are housed in net cups filled with some growing medium. The lid of the box will house these net cups.
Frame Hydroponic System
The frame hydroponic plan is very similar to the PVC hydroponic system. It uses the same NFT-based principles to feed nutrients and water to the plants.
The difference here is the increased verticality. By adding new layers of PVC pipes at different heights, you can grow more plants in the same space.
The amount of tubing required will increase, as will the complexity of the pumping system.
This particular plan houses the PVC pipes on a wooden rack frame. You can grow herbs and plants like strawberries and tomatoes with this system.
Deep Water Culture (DWC) Hydroponics
If you want to grow stuff like tomatoes and lettuce indoors, this system is ideal. It is best to use a dark plastic storage tote is perfect as the primary nutrient solution container.
Depending on the size of the box, anywhere from two to eight plants can be grown in this system.
The only other components required are an air stone, hoses to pump in oxygen into the nutrient solution.
The plants can be placed in net pots, underneath LED grow lights.
Recirculating Deep Water Culture Hydro System
Recirculating deep water culture systems are becoming more and more popular amongst the growers that we know. They offer not only tremendous yields but once you have your system dialed in, it is fairly maintenance free.
If you decide to build your own Recirculating DWC hydro system, understand that it is best to ‘dry run’ your system for a full 24 hours to ensure there are no leaks and to ensure that you have rinsed away any residue or materials that may be in the system after construction.

Drip Water Hydroponics
Drip systems can be simple or complex, depending on your requirements and budget.
In a passive system, you can forego the pumps and use gravity to bring the nutrient solution to the plants. This will call for some creative placement of the garden and reservoir.
Or you can just use a submersible pump and a network of thin tubing to deliver the nutrient solution is small amounts to the plants.
A growing medium is usually preferred for drip systems. Popular options include coir and perlite-vermiculite.

This is another largely inexpensive homemade system that uses a storage tray or tote to house the entire grow operation.
The ebb-flow system involves growing plants in a medium and flooding the medium with nutrient solution for a few minutes at set intervals. It is also called a flood-drain system.
This system will need a pump as well as a timer for automated operation.
These are only a few examples of some really solid hydroponics systems that you can build yourself. DIY hydroponics are fun to build and sometimes, they can be much cheaper to build than purchasing a pre-fab system from your local hydroponics store.
