How to Build a DIY DWC Hydroponic System for home.

If you want to save yourself some money you can follow these steps to build a DIY DWC Hydroponic System. This is very easy and will give you a 8 pot Deep Water Culture system for growing all types of plants. These are also very commonly used for cloning plants by starting their roots from just a clipping of a mother plant.  This is the first and easiest way to get your feet wet with hydroponics.

Tools Needed:

  • Plastic container for reservoir
  • drill w/drill bit
  • jigsaw / or 3″ holesaw
  • marker “optional if you are using hole saw”
  • paint “only if container lets light get in”

Step 1Step 1.

Find a container with a good flat surface for netpots to sit nice and flush. Something like this from Target will only cost you about $5-$7. The top being flat is key to having netpots that fit nicely.

You can skip this step if your container is already colored and not transparent. If you purchased a clear one like me, then you have to paint it. The plastic being very flexible and very smooth is not ideal for holding paint, so next time I do this I will keep hunting for a container that is already painted. I used a paint that was designed to stick to plastic. This makes the paint less likely to flake off.

This step we are going to mark and cut holes for the netpots. I used a marker and drew an outline around the netpots on the bottom of the lid to give me a guide as to where to cut my holes. Space them out as far as you can and only add one hole every couple of inches or more. Too many netpots will make your garden a little crowded. Then drill a starter hole in the center of each of the circles you just drew.

I recommend a 3″ hole saw for making the holes, but they are not cheap so you can also use a jigsaw to cut out the holes on the lines for the netpots. Try to stay on the inside of the line to provide your netpots a lip to hold onto. You don’t want the netpots falling inside the container because your hole is too large. After drilling your holes you should have a container that is almost ready to start growing.

Now you want to drill a small hole in the side to fit your air hose for your air stone. These air stones can be found for a couple of dollars at your local pet store, or I have some linked in my web store if you search under miscellaneous items. Here is my Hydroponic system with 2 air stones installed. You can use a grommet on this if you like, but it is not necessary.

Now all you have to do from here is set up your nutrient solution and hook up the air pump and you are ready to grow. You can see in this picture the 3″ netpots are in the container and it is ready to go. This total build should cost you about $7 for the container, and another $0.50 for each netpot. Air stones are only about $5-$8 each and the tubing is another couple of dollars depending on where you buy it.   Good luck, and if you have any questions or comments, please let me know.
